2012/08/09 | 578 | 1,944 | <issue_start>username_0: My Samsung Galaxy SII used to mount normally as a USB drive in Ubuntu until the 4.0.3 upgrade. Now the only two options are:
* connect as Media Device (MTP)
* connect as Camera (PTP)
neither of the above works properly with Ubuntu 12.04 so I could browse and manage files on the phone and the SD card.
Does Android 4.1 not support the device to be mounted as USB drive anymore?? I tried turning on USB Debugging in developer options but no difference...<issue_comment>username_1: UMS ([USB Mass Storage](http://en.wikipedia.org/wiki/USB_mass_storage_device_class)) was replaced by MTP somewhere with, at latest, ICS. Some kernels still may contain for UMS, but most won't anymore. So here are your options:
* Check the market for Apps which can enable UMS again (I heard mentioned a few who *should* be able doing so, including [AL Mass Storage Manager](https://play.google.com/store/apps/details?id=labs.antu.hw.storage), [USB Mass Storage Watcher](https://play.google.com/store/apps/details?id=com.skidmrk.umswatcher), and [Usb Host Controller](https://play.google.com/store/apps/details?id=hu.sztupy.android.usbhostcontroller) -- but no guarantees whatsoever, as I didn't try any due to lack of ICS devices
* install the mtp packages on Ubuntu (`apt-get install mtp-tools`)
Some helpful information on the second point:

2012/08/09 | 726 | 2,745 | <issue_start>username_0: I have rooted several Samsung devices and the underlying "goal" so to speak seems to be to get the `su` binary in `/system/xbin`and install *Superuser.apk*.
My question is why does one have to jump through all of these hoops to root the phone (install custom recovery and flash pre-rooted ROM or exploit the current installation)? Couldn't one just download a precompiled su, move it to the SD card, and run it via adb? The thing that seems to make a ROM "pre-rooted" is that it has Superuser and the su binary in their respective system paths. I don't see why it is so important that it is ran from `/system/xbin`.<issue_comment>username_1: The su binary needs both the execution and the setuid permission bit set. The first is needed that the file can be executed and the second is that it automatically runs with the file owner's rights (set user id, or setuid. In this case the owner is root. Read more [here](http://en.wikipedia.org/wiki/Setuid)).
Files on the external storage don't have the executable and setuid permission bits set and it cannot be granted without root rights. Note also that the SD card is mounted with the 'noexec' flag to prevent execution generally to boot:
```
shell@android:/sdcard $ ./su
/system/bin/sh: ./su: can't execute: Permission denied
126|shell@android:/sdcard $ chmod 4755 su
Unable to chmod su: Operation not permitted
10|shell@android:/sdcard $ mount | grep /mnt/sdcard
/dev/block/mmcblk0p1 /mnt/sdcard vfat [...],noexec,[...]
```
That's basically why you can't just copy `su` onto the SD card and then run it to grant yourself root.
Upvotes: 5 <issue_comment>username_2: Rooting involves exploiting the weakness depending on the android version, hence "*jump through all of the hoops to root the phone*"
Its a chicken-and-egg!
In order to exploit root, you need a unsecured adb daemon (i.e. the capability to remount `/system`) on the handset, and in order to have an unsecured adb, you need root! AND also, you need a unlocked bootloader.
Have a look at one [exploit](https://github.com/revolutionary/zergRush) called **zergRush** found on github; the function of interest is called `do_fault()` where an attempt is made to "break" the stack-frame of the `vold`'s daemon by connecting to the pipe owned by it, and cause it to crash by over-writing the stack pointer to point to a copied version of the shell `boomsh` which then runs from `/data/local/tmp`.
After reading the source, you will now realize, why copying the `su` binary is not enough to have the handset "rooted" and why hoops must be jumped through. And also, as the executable bit on the file-system level for the SDcard is blocked, so no go there - that is there for obvious reasons! :)

Is there any way to disable it?<issue_comment>username_1: You can go to settings-> applications and choose "all" tab to see the list of all apps and services. Scroll down to the end and choose voice search, which brings you an option to stop the service.
If your device is rooted, you can go one more step ahead and even uninstall the voice search app. In that case, you may need to have app like Link2SD.

Are they part of the android OS or something lower level than that? If I were to delete everything in these partitions will I brick the phone even after a complete factory restore from "Download mode"? If these are not in fact android partitions why do some ROMs flash them? What is the difference between `/firmware` and `/efs` and are these flashed with most ROMS?
I've been googling the partition structure of my device and these things are not clear. Please help me clear them up :)<issue_comment>username_1: According to this [linky](http://www.jayceooi.com/2011/11/19/how-to-backup-restore-samsung-galaxy-s2-efs/) here this is what it has to say

After reading the above linky, it would be prudent to make a backup of that partition otherwise well and truly hosed! :)
As for `/firmware` I am guessing that is where the original stock firmware goes into when updating via the official route a lá Kies.

I tried Picasa 3.9, but it would always freeze and I would have to force quit Picasa.
I tried Windows 7's photo software (Windows Live Photo Gallery), but it would export every photo, including cached websites.

2012/08/10 | 1,355 | 4,928 | <issue_start>username_0: I recently bought an Android tablet with a keyboard, and would like to use it to take notes of conferences, lectures, meetings etc. On a Windows or Linux notebook, I would use the excellent [LyX](http://www.lyx.org) system for this. LyX basically allows you to write structured text without worrying about the layout, saying "this is a #3 heading" or "this should be emphasized" instead of "this should be bold and a larger size". LyX then allows you to export your text as PDF, DOC, ODF, LaTeX and so on.
I am looking for an App that allows a similar approach to writing for Android. What I already tested:
* [Writer](https://play.google.com/store/apps/details?id=com.jamesmc.writer) is almost what I'm searching, a minimalist text editor that understands Markdown and saves its document as plain text on the Android device (no network necessary). I'd like a few more formatting options and an export feature, though.
* [Write:Tablet](https://market.android.com/details?id=uk.amimetic.journal.honeycomb) doesn't seem to have many structuring features
* Most "office" packages like Polaris Office do not offer format templates, but restrict the user to bold / italic / font size types of formatting
* Google Docs needs a constant net connection
So, I'm aware that this is a very small niche I am looking for here, and such an app would probably not make sense on phones, but is there another interesting tool for structured text creation?<issue_comment>username_1: Thanks for introducing Lyx, pretty impressive open source app.
There are two products from [Verbosus](https://www.verbosus.com/). I understood that Lyx is a Latex based tool and hence producing this link.
I am not confident enough whether suggested Latex editor will be equivalent to Lyx, but just trying to help.

* [NoteLynX Pro Outliner](https://play.google.com/store/apps/details?id=com.astrodean.notelynxpro): Hierarchical organization of notes, customizable CSS, lots of formatting options, hyperlinks and more, XML export
* [Wikilin](https://play.google.com/store/apps/details?id=com.mosharu.wikilin): As the name suggest, a wiki-style editor. Cross-platform, different formatting options
* [Ema Personal Wiki](https://play.google.com/store/apps/details?id=com.janwillemboer.ema): Another wiki-style editor with dropbox support, also a Windows version available
* [WikiMind note](https://play.google.com/store/apps/details?id=com.sweetrain.wikimind): Again wiki-style editor, cross-document links, macro support, encryption support
There are also several LaTeX editors on the market, but to me they looked rather complicated. From your question I take it you prefer something like wiki-style -- but feel free to offer a more detailed description of what you are looking for.

* [Write: Tablet Notepad/Journal](https://play.google.com/store/apps/details?id=uk.amimetic.journal.honeycomb)
To find the best application for your needs, first make clear the most important features, such as Dropbox sync or support of a specific Markdown dialect - for instance information about the latter is hard to find from the official app description. For this reason I cannot recommend one app (shopping recommendations should not be given at this place anyway).

Not only can you use the markdown syntax, it also allows you to write math equations(<https://www.youtube.com/watch?v=YfOnOXirIOs>) in a similar way to Lyx, so you can write your Math Homework on the go.

This one has a lot of built in image sites (like national geographic, nasa, ...):
<https://play.google.com/store/apps/details?id=com.dngames.picofday>
It looks like a normal wallpaper and is battery friendly.
The only problem I see is that most of the built in sources update once per day not every few hours, but you can define your own source of images.
You can also try searching for other similar solutions. I think the livewallpaper way is the best beacuse it has a lot less issues with lockscreens (you just choose the live wallpaper as the lockscreen wallpaper and it should leave the normal background intact.

I have a contact image that is no longer in my gallery but it is one of my contact's avatar. I remember taking the photo and making it the avatar. I've went into my Google Contacts via the web but it is not there. The contact does not have a facebook or any other type of account. So it must be somewhere on the phone.
I have a Droid X with Gingerbread.<issue_comment>username_1: The contacts is actually an app, hence as other Android apps store it's data, this app also stores in a SQLite database.

You should download program from Google Play called "Save Contact photo" then you will see all your contacts there and you can share those contact photos via Bluetooth(should have another phone for that!). And then you can see that photo in another phone's gallery, so you can easily transfer it via Facebook or Whatsapp.

Whenever I get a new phone, I simply transfer/copy the contents of my 'pics for Contacts' folder, which is located in my Internal Storage folder, via Bluetooth to the new phone.
A SIMPLIER WAY of course would be to just start saving your Contacts in your Google account under your main account. This way, any contact, together with its contact photo, will be saved in Google Cloud. You stated that this does not seem to work for you. Everytimre I buy a new phone and connect it to my main Google account during initial phone setup, my Contacts and their pics transfer onto my new phone without a problem.

2012/08/10 | 2,587 | 11,526 | <issue_start>username_0: Isn't Android a common kernel that is used across all devices? For example, CentOS will install on Dell, HP, and a variety of other hardware. Sure there are different modules, but it's still CentOS nonetheless.
What is the reason why CyanogenMod is always "broken"? I always hear in forums they are working on porting this driver or that driver. If they used the same kernel, wouldn't the drivers just work with it? I also see a million different types of kernels for different devices.<issue_comment>username_1: Well.... drivers and the kernel are not exactly the same.
Drivers are what control the cell antenna, wifi, bluetooth, etc. These are proprietary drivers because the manufacturer has to create a way (the drivers) to talk to their hardware.
The kernel is an intermediary level between the OS/application and the actual drivers (or cpu or memory or any other hardware). It is what allows your OS/apps to interface with these hardware components.
All of the millions of kernels you see are really not that much different from each other. Typically a programmer/modder will take the existing kernel and "tweak" it to try and get a difference performance out of it. You can essentially say that they are only adjusting (for the most part) the "configuration" of the kernel. In the Android world, these modders are primarily looking at: over or underclocking the CPU clock (important for either saving battery life or trying to run most process intensive applications such as video game emulators or video playback), or they are looking at under-volting (to save battery life by running your CPU outside of its original set parameters... which varies in effect person to person because no two CPUs are made 100% exactly the same).
Upvotes: 2 <issue_comment>username_2: Kernels vary from manufacturer to manufacturer. A lot of those kernels come from the pure stock kernel line of sources found on CAF, what these manufacturers do is take those stock sources, modify them to suit based on the board/chipset used, also, implement their own drivers.
Take a good look around you, there's variations of touchscreens, variations of wifi chipsets, not to mention, accelerometer, sensors, batteries, compass, sound, graphics.
Taking one kernel source from for example HTC will not work on a Samsung, and vice versa.
The manufacturers are free to cherry-pick or out-source various bits that get incorporated into the circuit board. There is no hard or fast rules involved. Hence the lot of hacking/modifications to get the kernel to work properly.
You must not ever, compare to desktop Linux distribution kernels in which it has PCI, PCI-Express, SATA, VGA, SVGA, USB, Ethernet as they are a totally different ball-park game. The major differences with CentOS and with Android's Linux Kernel is this - **ALL** drivers are compiled either as modules or built-in, hence any Linux distribution will simply "work out of the box". Again, with desktop Linux distributions - you have one architecture - x86 hence one Linux kernel from say a Dell PC, can work out of the box on a Lenovo **provided** that the bog-standard drivers are compiled.
Don't forget, in the Android world, there's variations of the kernel built for specific ARM chipsets, such as ARMv6, ARMv7, there's TEGRA, there's EXYNOS, and they are binary incompatible with one another. Hence if a kernel is compiled for TEGRA, forget it, it will not work on ARMv7!
The reason some kernels on Android appear to be "broken" is down to the manufacturer. Some (Zte is one very good example) release a butchered source that may compile from source but fails to boot due to a missing driver that is not covered by the GPLv2 or GPLv3 licence. That's the problem, hence some hackers have to go scouring around github looking for some clues; some manufacturers, if not all, do comply. The current incarnation of Zte's source is purportedly to be 2.6.35.7, but in reality its actually 2.6.32.9 source base with a lot of modifications thus does not represent the true kernel source for 172.16.31.10!
This is where the manufacturers have to release their respective sources, not just out of being compliant with GPLv2 or later, but rather, for the community to be able to mod it, such as adding overclocking capabilities.
Hence there's hacking involved behind the scenes and a lot of messing about with drivers trying to get it to work, and its not easy to debug either.. Some drivers may be cross-licensed, **BUT** cannot be distributed depending on the clause and conditions as negotiated.
Thankfully, that's all changed now with kernel 3.x.x. line of sources, as Android drivers are now integrated into the mainstream sources. But there's a gotcha!
Try porting a 3.x.x. kernel to an existing handset that is about 12-18 months old; Not a snowball's chance in hell would it work, that's because, of the differing factors, the 3.x.x sources is vastly different to the 2.6.x source and would take a lot of hacking to get it working - I should know, have tried porting 2.6.38.6 source for the Zte Blade and failed.
Likewise, the latest kernel release 3.0.1 - when working on the ics4blade project over on Modaco, have made numerous attempts to port it but that's down to the simple fact that Zte made a very bad mess of the source which rendered porting nigh on impossible.
Upvotes: 6 [selected_answer]<issue_comment>username_3: The reason is because Android's Linux kernel are generally not compiled on Android itself, instead it had to be cross compiled from another computer. This causes various issues, because the device configuration are not available on compile time, and it is not feasible to compile a generic kernel with all drivers due to space limitation (whereas most desktop distros simply had all drivers compiled into modules loaded from an initramfs). Therefore developers had to figure out which drivers to package for each particular device. Not only that, each drivers generally have a dozen or so of compile time options to toggle various driver features, and manufacturers usually do not release their official configuration (the worst offenders don't even open source their drivers, or didn't keep upstream's copy of the drivers up to date). Because manufacturer's don't release their configurations, often the slightly different configuration that the developer uses will expose subtle bugs that doesn't exist with manufacturer's configuration.
Driver programming is much more difficult than application programming, as there is no kernel that shield you from the fickle hardware that have a specific real-time timing requirements and the such, and this means even having a different performance characteristic may cause the driver to miss some hard real time events from the hardware; these misses may surface as either bugs or performance issues.
Another issue is binary incompatibility. There are two cause of binary incompatibility, first is CPU type, which has been covered by username_2 well, but the other issue which is more relevant to porting is the ABI incompatibility (application binary interface). If manufacturers don't open source their drivers, then developers had to use the compiled module from a stock ROM. This raises various ABI incompatibility issues, since the driver modules itself have specific expectations about, for example, struct layout and function calling parameters, and when the kernel is compiled, it does not have the header file to describe the ABI at the time the driver is compiled, so developers had to reverse engineer the driver to create a header file or the header files in the source tree might have been modified heavily since the driver is compiled and developers had to revert those modifications to make the kernel compatible again with the driver's ABI. Unlike compiling from source, compiling for binary driver will not trigger compilation error due to function parameter mismatch or struct incompatibility, it will simply just crash your device while it's running, and debugging these issues are very difficult. In the PC world, we're familiar with the mess that nVidia and ATi left us, due to their insistence on releasing binary only drivers, imagine having that mess for all drivers, imagine the "fun" it creates.
PC hardware are also generally better standardized than mobile hardware, most PCs don't need drivers for vibrators, accelerometer, gyroscope, 3G radio, proximity sensor, NFC, etc. Even on devices that have 3G, it usually connects to the hardware using standardized connections like PCMCIA or PCI-E.
Upvotes: 3 <issue_comment>username_4: The PC architecture is built around commodity parts because it started out as clones of a specific product, the IBM PC, that were specifically designed to be compatible with it, and therefore with each other. Generally speaking, you could take a program or peripheral device from one PC-compatible and put it into another, and expect it to work. That ability is useful enough that people have continued to demand it even as the technology evolved. You can put a PCI Express card in any modern PC just like you could put an ISA card in any PC clone back then.
Smartphones have no such history. They're designed as monolithic products, a complete system consisting of hardware and software that "just works" as-is. There's no expectation that people will take parts out of one phone and put them into another, so engineers don't have to take interoperability into account when they design their products.
Even within the Linux kernel source tree, there's [a lot of fragmentation in the drivers for ARM platforms](https://lwn.net/Articles/439314/). Since phones are usually designed behind closed doors, engineering teams at different companies often end up doing duplicate work, designing basically the same hardware as their competitors and then writing their own drivers for their own design. Once they're done and the product is released, they go straight to working on the next one; it's not worth their time to go back and refactor the drivers for past products or merge them with competitors' drivers. The result is a plethora of one-off drivers for devices that are similar but not quite the same.
In addition, smartphones are usually based on [SOC](https://en.wikipedia.org/wiki/System_on_a_chip)s that have specialized hardware integrated together with the processor. For some of this, it can be more than a matter of whether to load or not load a certain driver; the kernel as a whole may need to be built with special configuration options for running on one SOC, which are incompatible with the special options needed to run on another SOC.
Upvotes: 4 <issue_comment>username_5: Phones and other embedded do not have a BIOS to provide abstraction between the hardware and OS as a result the OS is compiled for the hardware it is deployed to. Even devices using the same chip set can can be configured in different ways (using alternate comms buses etc.) \the result is that the kernel has to be compiled accordingly. As there is no expectation of changes in hardware there is no hardware detection performed. Kernel boots faster and is smaller as a result - this is a standard principle of an embedded OS
Upvotes: 2 <issue_comment>username_6: CentOS installs on different hardware, but,
1. It's all PCs which vary less than phones,
2. A Ubuntu kernel, Debian kernel, and Elementary kernel are all different kernel sources.
As for your second point, see the answer(s) posted earlier.

I have this kind of firm url, `https://www.google.com/a/cpanel/firm.com`. I want to have an IMAP -email account on Android. How can I do it?
I am using the app `"My email"` by which things do not work. If I use the native Gmail -app, things work out of the box. As for the `"My email"` -software (that gathers all emails, not just Gmails, under one mailbox), I selected
```
imap
Email: <EMAIL>
```
**Incoming**
```
Username: myName
Imap Server: imap.gmail.com
Port: 993
Security SSL
```
**Outgoing**
```
SMTP server: smtp.gmail.com
Port: 465
Security: SSL
Require sign-in: yes
Use the same settings as the incoming server: yes
```
Pressing `Next` fires `"Username or password incorrect"` with `"s@gmail@firmA@g"` while `"Unable to open connection to server"` with the latter. So how can set up the Google Apps Gmail on Android?<issue_comment>username_1: You need to enable IMAP on your account.

I will say that I prefer FTP'ing to my Android using [Filezilla](http://filezilla-project.org/) and [Software Data Cable](https://play.google.com/store/apps/details?id=com.lyy.softdatacable&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5seXkuc29mdGRhdGFjYWJsZSJd).

I add someone friend and I get her phone no. and email id in my smartphone (provided her privacy settings permit it). It also syncs photos and missing data with existing Google and local contacts.
I have tried FriendCaster's contact sync. It sucks because of Facebook's privacy policy. Facebook doesn't share phone nos. and email addresses of friends to any app.
So, all apps which login using oAuth have problems with contact sync (correct me if I am wrong). I don't have problem sharing fb password to an app if it can do pure Facebook contact sync. Is there an app?<issue_comment>username_1: Sure you can remove the official Facebook app in fact I also uninstalled it by resetting to factory setting and wipe user data.

Extremely frustrated at this point. I don't think calling t-mobile can help because the phone was AT&T. Samsung probably wouldn't help either because I bought it on ebay.

1. Kill a list of custom apps loaded from a file
2. Run one custom app loaded from the same file
3. When that app is closed, restore killed apps
If that's not possible, then could it be split into two scripts, one that kills all the custom apps and launch one custom app, the other to restart the custom apps?
All of this is on a rooted phone.
Thanks.<issue_comment>username_1: You can use an [Tasker](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm) to kill apps when you launch your game. And you are also able to do the opposite, when your game gets closed, Tasker can initialize other apps.
You may use the trial version to test this, but I believe that better results can only be achieved with root.
Tasker

[Tasker by Crafty Apps](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm) available from Google Play Store (4,49€)

Whenever you want to play your game, just launch Fast Reboot and then launch your game. It will free up some extra RAM without interfering with anything critical, and it is much easier than a script.
Don't worry about restarting the apps, because as t0mm said, they will almost immediately restart themselves. (You can launch Fast Reboot twice to see this)
This solution will solve your needs without having to pay for Tasker.
Although, I *do* recommend that app- it can do anything.

```
pm enable package_name
```
and
```
pm disable package_name
```
then you should restart some application services like whatsapp in order to restart checking automatically (Not sure if they will automatically restart services since package has been disabled) to do that you can use `am` command, but not sure what where will be the best arguments. You can use the `logcat` command, to debug what intents are being launched.
If you only kill the application it automatically will restart few seconds.
In SManager, at this moment it is not possible execute script after app has finished. But it could be a new feature.
You also should kill SManager in the las line of the script.
```
killall os.tools.scriptmanager

2012/08/12 | 3,201 | 11,535 | <issue_start>username_0: I spent almost entire day looking for decent apps for maps (decent = free, up to date, being open-source is a plus).
I ended up with TrekBuddy, **GoPenS**, **RMaps**, Maverick, OruxMaps (the emphasized ones look the best, in my opinion).
However, now I have another problem -- how to prepare maps for those apps (please help me with one, and hopefully I will manage the rest) for off-line usage?
I would like to go on a ride, pick up the phone somewhere in the forest and see on the map where I am. For now it works only with internet connection, but without it I have a huge-scale map and after zoom-in blank space or "loading" icon.
In short -- **QUESTION** -- how to feed phone/apps with maps, so I could zoom-in/out map freely when I am in the wild (offline)?
*I would like avoid tricks like relying on caching -- so "solution" to scan interesting region with all possible scales and in such case acquire off-line version of the map is a no-go!*
**Clarification:** I am not looking for another app (however thank you for the hints/links), I am looking for **maps** (data). I want to get map from on-line version (which are automatically downloaded) to off-line one.<issue_comment>username_1: Thanks to your clarification I assume it is OK when you can acquire the map data from within the app. In this case I'd suggest you take a look at [Locus Maps](https://play.google.com/store/apps/details?id=menion.android.locus), which is an excellent solution. It has already a lot of map sources built-in -- and if that's not enough for you, the [Map Tweak Addon](https://play.google.com/store/apps/details?id=com.mjk.locusmaptweak) offers additional sources.
Additional ressources on Locus Maps include:
* [an English Howto](http://forum.asamm.cz/viewtopic.php?f=21&t=891)
* a [blog on maps use](http://androgeoid.com/2011/03/locus-a-gps-mapping-application-part-ii-maps/) in/with Locus Maps (including some map sources listing)
* a manual/howto on [how to convert your own KML/KMZ sources](http://forum.locusmap.eu/viewtopic.php?f=21&t=891) to be used with Locus completely offline
I could name even more ressources -- and will do, if you wish.

They provide a 10-mile radius of map cache, and since you can point to different locations and cache them, you can virtually cache the entire world.
1. Open Google Maps App;
2. After the map loads, press the menu button and select "Settings";
3. From the "Settings" panel, select "labs" and enable the "Precache Map Area" option.
4. Return to map view, navigate to the area you want to save for offline use;
5. Once loaded, click on it to open the detailed view and select the option "Precache map area".
Repeat this process as many times as you would like to cache all the desired areas.

**Vector Maps versus Bitmap, Pre-rendered, Tiled Maps**
Here's the difference: Caching Google Maps or any other pre-rendered maps stores dozens to thousands tiles of (bitmap) images on your device. Even though these are compressed, they take up gigabytes of storage, especially if you're in to storing maps for a full country.
Also, bitmap images are just that: Images. Mapping, and especially navigation applications cannot interpret what's displayed on the image. So they don't know about the nearest gas station, bus stop, what river you're on paddling, etc.
A vector map is in some special data format. To be displayed it has to be rendered which means an image must be calculated out of the raw data first. So the biggest drawback is that applications using those might be more cpu intensive. However, depending on the quality and contained features of the vector map, and the quality and features of the application, you can query the map for navigation by car, by foot, by boot, by bike. You can get info about nearest restaurants, or the nearest letterbox.
Another main advantage of vector maps is its much smaller size compared to bitmap data. While a pre-rendered map tile image may contain some greenish and varying pixel data to represent a wooded area which is linear proportional to the covered area, the same vector map may just say "wooded area" and store the coordinates of the boundary.
Another advantage thus is that the application decides how to render said wooded area and thus the user has some influence on how she likes maps to look like. You might be able to tell your mapping application to switch to a red/blue/black color scheme during the night without having to download a second set of bitmap tiles. It's just recalculated on the fly upon changing some settings, and does not take up any additional memory.
The amount of storage, and the available feature set is restricted by the data contained in the vector map. So depending on your needs, and those of your applications, some may want to have the full open street map data, while some get by with just a basic set.
Also, with vector maps and their small amount of storage, and their ability to customize their rendering inside applications, there's no need to use any additional application on your desktop to prepare the maps. Download files, and off you go. While in theory, this works, in practice the original data files of the OpenStreetMap project have to be converted into a syntactically different format. See below.
Coming back to howtos and applications, I'm still a beginner on android. Here's what I use today.
[Open Street Map](http://www.openstreetmap.org/) is a project to provide full featured vector maps for free. Like Wikipedia, the map data can be improved by users, and this happens all the time.
**Mapsforge Vector Maps**
Pre assembled vector maps of open street map can be found courtesy of the [mapsforge project](http://code.google.com/p/mapsforge/), at <http://download.mapsforge.org/maps/>
**Using original Open Street Map files**
The above mapsforge files can be used as-is, and are thus the most convenient solution. However, if you'd like to start from the [original Open Street Map files](http://wiki.openstreetmap.org/wiki/Planet.osm#Downloading) you can follow [this guide](http://wiki.openstreetmap.org/wiki/Locus) to convert the original files from the [PBF format](http://wiki.openstreetmap.org/wiki/PBF_Format) to the map format using [Osmosis](http://wiki.openstreetmap.org/wiki/Osmosis). A typical command line example would be:
```
osmosis --read-pbf "hungary.osm.pbf" --mapfile-writer file="hungary.osm.map"
```
**Locus**
As a mapping application you can use [Locus Free](https://play.google.com/store/apps/details?id=menion.android.locus&hl=en). Download and install.
Download any of the vector maps file and store it on your phone in the folder `/mnt/sdcard/Locus/MapsVector/_themes/`. Personally, I download the maps on my desktop pc, store them in a folder which I share via Samba on Linux, or share on a Windows machine. Then I use any android filemanager ([Ghost Commander](https://play.google.com/store/apps/details?id=com.ghostsq.commander&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5naG9zdHNxLmNvbW1hbmRlciJd) with [Samba plugin](https://play.google.com/store/apps/details?id=com.ghostsq.commander.samba&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLmdob3N0c3EuY29tbWFuZGVyLnNhbWJhIl0.), [ES File Explorer File Manager](https://play.google.com/store/apps/details?id=com.estrongs.android.pop&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5lc3Ryb25ncy5hbmRyb2lkLnBvcCJd)) on my phone to copy the files from the shared location to the Android device's Locus mapping folder.
**OruxMaps**
You can also use the [OruxMaps](https://play.google.com/store/apps/details?id=com.orux.oruxmaps&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5vcnV4Lm9ydXhtYXBzIl0.) app. Unfortunately I have not yet found a way to use both applications without having to store the map data twice. ([SD Cards do not support symbolic links](https://superuser.com/questions/216332/is-there-anything-like-a-link-or-shared-mount-point-for-fat32-folders-in-linux-a/377737#377737). If you've got the data on internal memory you could use them, and store the maps only once). You can use again your preferred filemanager on android to copy the `*.map` files from the aforementioned Locus folder to the folder where OruxMaps stores its map files. By default this is `/mnt/sdcard/oruxmaps/mapfiles`
Switch to the new map:
1. Click the upper right hand "map" icon
2. Click "new map" in the pop up menu
3. Click "offline" in the upper right hand side
4. Choose any of the \*.map map files
Note that in OruxMaps you can navigate through subfolders. So if you like you can use your filemanager to organize maps in subfolders. Hint: You could fully copy the mapsforge data into your OruxMaps map folder, and never worry anymore :-)
Note also that if you have the OruxMaps app open while you are copying new map files into it's data folder, then you may have to click on "reset map sources" in the "new map" dialogue to ensure it rereads the map folder for new files.
Here's [a howto on those two applications for theming your maps maps](http://www.openandromaps.org/en/manual). As mentioned before, depending on the app, you may influence the way the vector maps are rendered. This includes color settings as well as which data is to be included in the display and which is not.

Is here any way to make android only automatically connect to my wifi without forgetting the other's password? It is long and impossible to memorize so forgetting the network is a huge pain.

* [Wifi QR Code Generator](https://play.google.com/store/apps/details?id=com.madeng.wifiqr)
* [WiFi QR Share](https://play.google.com/store/apps/details?id=com.sudomakemeanapp.wifiqr)
you can generate a QR Code of your friend's Wifi connection, print it, laminate it (for protection), and put it into your wallet. Now, whenever you want to use that Wifi network, take out the QR-Code, scan it with [Barcode Scanner](https://play.google.com/store/apps/details?id=com.google.zxing.client.android) -- and get connected. For a "log-out" simply disconnect, and *remove* the network from your list (to keep your device from autoconnecting).
Not quite elegant -- but it saves you from typing the long password everytime. Side-Effect: Print out the QR multiple times, and give it to your friend's for other guests. Do the same for your own Wifi. Now you never have to tell your passwords: To permit your guests to connect, somply show them the QR-Code to scan (and have them delete the network from their devices when they leave, as Android stores Wifi-passwords unencrypted).

Now, whenever you want to use that Wifi network, take out the QR-Code, scan it with [Barcode Scanner](https://play.google.com/store/apps/details?id=com.google.zxing.client.android) -- and get connected. For a "log-out" simply disconnect, and *remove* the network from your list (to keep your device from autoconnecting).
Not quite elegant -- but it saves you from typing the long password everytime. Side-Effect: Print out the QR multiple times, and give it to your friend's for other guests. Do the same for your own Wifi. Now you never have to tell your passwords: To permit your guests to connect, somply show them the QR-Code to scan (and have them delete the network from their devices when they leave, as Android stores Wifi-passwords unencrypted).

BUT there is a handy little app that lets you create widgets that let you switch your networks with a single tap. So when you realize you are connected to your friend's network, simply press the button on your homescreen and you will be connected to your own network again.
You can find the app here: [Wifi Manager](https://play.google.com/store/apps/details?id=org.kman.WifiManager).

The settings will be save in regular text and they'll easy to read and figure out.
If you have a [Root explorer](https://play.google.com/store/search?q=root%20explorer&c=apps&docType=1&sp=CAFiDwoNcm9vdCBleHBsb3JlcnoCGACKAQIIAQ%3D%3D%3AS%3AANO1ljIucBM&hl=en) like ES file or any other you can find it by looking here → `/data/misc/wifi/wpa_supplicant.conf`
Note : *Also there are some apps that let you do this if you don't want to try and find the file yourself*

1. Use [tubemate](http://m.tubemate.net/). With this app you can browse YouTube and download the video just like you would download from websites like keepvid.com.
2. *The latest version of YouTube allows the videos that you opened or YouTube thinks you'll watch or have added to watch later queue to be downloaded in background so that you can watch it later. Read [here](http://mashable.com/2012/06/27/youtube-android-offline/).* -**> The preload option is no longer available in the official youtube app since version 5.6, see google support note [here](https://support.google.com/youtube/answer/4629400?hl=en)**
>
> For the first time, YouTube will start downloading videos it thinks you might want to watch, whenever you’re plugged in and on Wi-fi.
>
>
> That’s great news for commuters, for example, who can now watch videos when outside their mobile coverage zone (or without paying for costly video downloads over 3G).
>
>
> YouTube, careful to draw a distinction between this and total downloading of its vids (which breaks its terms of service), is careful to point out that you’ll still need to be online for the first second when you press play.

Upvotes: 3 <issue_comment>username_2: I used to use Tubemate. It has many options, one of which is the ability to download the audio part alone so that you can also just listen to the video rather than watch it.
I later implemented a YouTube downloader script in my [browser app](http://www.vsubhash.com/article.asp?id=126&info=Subhash_Browser_Feed_Reader_app). It has a flaw though - new videos loaded in the same page will not update the download link.
With the desktop browser disguise option and [a Greasemonkey script](https://vsubhash.wordpress.com/2015/09/18/download-any-youtube-anywhere-2016-user-js-for-opera-12-x-firefox-and-android/), it might be possible to make it work in a mobile device as well.

2012/08/13 | 1,099 | 4,094 | <issue_start>username_0: On my HTC One-X the Camera app can take videos or photos. When recording video you can turn the flash on to provide some illumination.
Is there a way of doing this while in the camera mode when composing a shot?
The other night I was in the garden in the pitch black trying to take some photos of some nocturnal animals. When in camera mode the viewfinder is also pitch black which made it very difficult to line up the photo. I ended up having to record a video, turn on the flash for some light and then take photos while the video was recording.
This is not ideal, and so I wondered if there is any way to get the flash to provide light while aiming the camera for a normal photo.<issue_comment>username_1: Yahoos settings for android:

I'd like to confirm that the phone is real, how do I prove it? I had the chance to play with the operating system and it is like my Galaxy S, but with a larger screen. I cannot "open" or connect to laptop, but I can play with it.<issue_comment>username_1: Gadgets in Thailand are way cheaper than anywhere else but, there's a small heads-up - more than likely, it will have a CSC code for Thailand, Asia, so the updates on that would be somewhat, slower than the rest of the region zones.
Having said that, you can flash it with a different regional CSC code. So go for it, when the first Samsung Galaxy Tab 7" (P1010T with Wifi only) came out, it was on sale there in Thailand - a mate of mine was there, and got it for me - 200 euros - it was a steal, it would have been about 450euros to buy in the EU.

5. enter your passcode.
6. click whichever security setting you used before.

Open Settings and then navigate to `More` and then `Security` and tap `Clear Credentials`. After that you can navigate to `My Device` and then `Lock Screen` where you can change the screen lock to whatever you desire.
I'm not sure what other credentials it clears besides the screen lock but I haven't found anything so far.
I've tested this on a Samsung Galaxy S4 running Android 5.0.1. The exact locations and names of different settings may be located in different places depending on your device.

2012/08/13 | 964 | 3,500 | <issue_start>username_0: I own a Motorola Milestone 2, also called A953 (apparently this is different from the Droid 2 Global). It used to have Android 2.3 with Motoblur middleware. It was bought independently from any phone carrier (so it was not bought from Verizon for instance). I rooted it, installed ROM Manager, [Droid 2 Global Recovery Bootstrap](http://market.android.com/details?id=com.koushikdutta.droid2.bootstrap) and ClockworkMod Recovery. From ROM Manager, I could successfully reboot my phone into Recovery mode, allowing me to back-up my data for instance. Until this stage everything went fine.
What lead to my problem : I also wiped the cache and installed CyanogenMod 7.2 and the Google apps from ZIP files and from the Recovery Mode interface. But now my phone is broken. When it now boots, it shows the stylised M logo, but then switches to an entire black screen. The phone is still on so I have to pull the battery to shut it down.
I would like to reboot into Recovery Mode but this doesn't work : I am never able to see the Recovery Mode logo (a warning sign with a little android). How should I do it ?
What I have tried : I tried to boot while holding the Power and the 'X' button, as adviced on different forums. This still leads to the black screen. At this state, pressing the Search hardware button does nothing. Holding the Power and the Volume Up button has no more effect.
I am able to enter Bootloader Mode by holding Power and Up Arrow.
I also tried to use a live CD from [here](http://www.droidforums.net/forum/droid-2-global-hacks/170060-tool-ezsbf-d2g.html#post1726853) with ezSBF, but I get errors in the process and then my phone reboots in Bootloader mode and shows the following error:
```
Critical Error:
FEBE 0047
```
After that I still cannot get to Recovery Mode.<issue_comment>username_1: Power up while holding the X and when you see the yellow exclamation mark after the Moto Logo, hold Vol Up+Down. That should get you to the Recovery Screen.

1. Download the best SBF file from [here](http://sbf.droid-developers.org/). Among those corresponding to your geographical region and carrier, choose the most recent one.
2. Flash it to the phone by using either "[sbf\_flash](http://blog.opticaldelusion.org/search/label/sbf_flash)" if you are on Ubuntu, OSX or another Linux, or by using "RSD Lite" if you are on Microsoft Windows.
The result is that the phone is unbricked. Among other things, I now can go back to Recovery Mode.

[Here](http://wiki.cyanogenmod.com/wiki/Terminology) is an explanation of commonly used terminology (fastboot, adb…).
There are some differences between manufacturers/brands:
* Google: very easy, with standard tools (adb, fastboot)
* Sony: rather easy, all standard tools + special tool (flashtool by androxyde), locked bootloader that needs an unlock code from website (not possible for all branded phones)
* Motorola: rather hard to mod, locked bootloaders
* Samsung: rather easy, unlocked bootloaders (except for some branded phones)

My battery last long for 12- 16 hours only. I know there are lots of application which continually running and fetching data from internet.
I have both options available, in my office i have Wi-Fi and i also has 2G plan in my sim account, both give me desire speed.<issue_comment>username_1: The generic perception is that networking via Wi-Fi cause less drain on your device's battery than connecting with 3G.
During the data transfer, if you use both connections to perform the same download, you will find that Wi-Fi is more efficient since it transfers stuff faster than 3G, thus leading to less consumption of your battery.
Rare exceptions may prove otherwise, but 3G faster and with stronger signal than Wi-Fi is a grandpa's fairytale ;)
One important thing to account for, is the network coverage:
If you stay a large amount of time within a limit coverage area, either for 3G or WiFi, disable the one who's suffering from low coverage. Your device will constantly be searching for available network, and that's just energy wasted on fruitless searches.
Being this usually the cause for complain on the battery life.

When it comes to big downloads etc, WiFi is more efficient. Reason: Due to slow speed, 2G will continue to drain battery for 2 hours when WiFi quits downloading within 5 minutes.

2012/08/14 | 2,106 | 7,697 | <issue_start>username_0: Summary
=======
I have been having problems accessing the K9 log messages using aLogcat, see below for more details. What I would like to know is:
* Why are no log messages from K9 appearing in the aLogcat log viewer?
* Does anyone have any suggestions as to how I can see the full text of the errors which are occurring when trying to sync my K9 folders?
* Could something have changed in Jelly Bean which lead K9's logging to stop working?
* Since there seem to be remarkably few messages being shown by aLogcat in general, has something has changed in Jelly Bean which could mean that it is no longer able to access all messages?
Detail
======
I have recently been having connection problems with K9. My folders fail to sync and the folder list ends up full of socket errors (`libcore.io.ErrnoException:`) or ssl errors (`javex.net.ssl.SSLException:`) etc. where the *last checked time* should be. I get different messages depending on which problem is occurring at the time, but I can't see the full text of the error message, so it's difficult to guess what the cause might be.
Thinking that the log files might contain more information, I followed the instructions at [Recording a debug log](https://github.com/k9mail/k-9/wiki/LoggingErrors), enabled debug logging in K9, installed [aLogcat](https://play.google.com/store/apps/details?id=org.jtb.alogcat) and tried to look at the logs. Sadly, whichever log buffer I select (*Main*, *Events* or *Radio*), there appear to be no messages from K9.
If I add the suggested `(k9|AndroidRuntime)` regex filter then I see nothing in *any* of the logs. If I remove it then *Main* contains mostly garbage collection messages, *Events* seem to contain mostly messages from aLogcat itself and I haven't seen a log message in *Radio* yet.
If it makes any difference, I'm using a Nexus 7, but I would have thought that logging would have been to a standard location which wouldn't change between android versions.<issue_comment>username_1: I've seen this behaviour in K9 when my mail server updated it's SSL certificates. The fix was to long-press the account, select `Account settings -> Fetching mail -> Incoming server` and just hit `Next` through the pages to confirm your settings until you get the popup about the certificate (this might not appear if everything is OK with the certificate, mine had a wrong vhost). Confirm the certificate and just go through the rest of the settings and you account should start to work.

It seems that there is no way to see these log messages **on the device** without **root access**, but if you do have root access, there are a couple of options, either **grant the required permissions** to *aLogcat* or consider using a horrible hackTM to view them directly.
View the log files on your PC or workstation via `adb`
------------------------------------------------------
If you can connect your Android device to a PC or workstation, then you can access the logs via the `adb` command.
To do this on Windows, first you will need to install the [Android SDK](http://developer.android.com/sdk/index.html) (which will require the [Java SE SDK](http://www.oracle.com/technetwork/java/javase/downloads/index.html)) and add the `android-sdk\tools` and `android-sdk\platform-tools` to [the system path](http://www.java.com/en/download/help/path.xml). Then enable USB debugging on your Nexus 7, plug it in via USB, and install the *Android Composite ADB Interface* from `android-sdk\extras\google\usb_driver` (I had to force Windows XP to look here, it wouldn't find the drivers on it's own).
For details of how to get `adb` up and running without the full Android SDK install, or on Mac or Linux machines, see [Izzy's excellent answer](https://android.stackexchange.com/a/42475/4229) to
[Is there a minimal installation of ADB?](https://android.stackexchange.com/q/42474/4229)
Then you can open a shell (i.e. a `cmd` window) and run the command:
```
adb logcat k9:V *:S AndroidRuntime:E
```
* I have confirmed that this works on my non-rooted Nexus 7.
Grant permissions to *aLogcat*
------------------------------
If you have **root access**, you could consider granting the `READ_LOGS` permission to *aLogcat*, as suggested in this post [aLogcat/CatLog/Lumberjack not working? Do this ...](http://forum.xda-developers.com/showthread.php?t=1793465) on the [xda-developers forum](http://forum.xda-developers.com):
```
pm grant android.permission.READ\_LOGS
```
To grant this permission to `alogcat` or `alogcat.donate`, you would use one of the following commands, depending on whether you are running the donate version or not:
```
pm grant org.jtb.alogcat.donate android.permission.READ_LOGS
pm grant org.jtb.alogcat android.permission.READ_LOGS
```
According to one post on *android-developers* and the [ticket](http://code.google.com/p/android/issues/detail?id=34785), the permission grant survives reboot and update, but not uninstall/reinstall.
Sadly since this requires root access, whether I run this on the device or on my PC (prefixed by `adb shell`) I just get the error:
```
Neither user 12345 nor current process has android.permission.GRANT_REVOKE_PERMISSION
```
* I cannot confirm that this works, since my Nexus 7 has not been rooted.
Consider using a horrible hackTM
--------------------------------
If you have **root access**, you could consider making `logcat` **setuid root** and running logcat from the device shell, as suggested in [this answer](https://android.stackexchange.com/a/28864/4229) to my [How can I access android log files on my Nexus 7 without root access?](https://android.stackexchange.com/q/28857/4229)question:
```
chmod 04755 /system/bin/logcat
logcat k9:V *:S AndroidRuntime:E
```
* Again, I cannot confirm that this works and I would probably only use it as a **last resort**, given the security implications.

This appears to be a change in Jelly Bean which affects all applications which may try to read the log files.
Apparently [READ\_LOGS permission is not granted to 3rd party applications in Jelly Bean](https://groups.google.com/forum/?fromgroups#!topic/android-developers/6U4A5irWang). Since this link seems to be unreliable:

My suspicion is that *aLogcat* is only seeing messages generated by itself and it's vm.

Anyway, I've recently updated it to Jellybean, but I realised that I didn't have something that was showing in the article - [the toggles they showed in the Notification bar (in the right hand image)](http://1.androidauthority.com/wp-content/uploads/2012/06/statusbar.jpeg).
Are these provided in the standard ROM, by an app, or in a custom ROM? I can't seem to find them.<issue_comment>username_1: The notification toggles are not part of standard Android OS (ICS, Jelly Bean, etc.) Some 3rd-party apps give this feature, although they are usually not very stable. Custom ROMs like CyanogenMod and AOKP provide this functionality as part of system settings.
Upvotes: 2 <issue_comment>username_2: These toggles aren't part of Android. Third party ROMs like CyanogenMod and MIUI, and certain skins that Hardware manufacturers put on Android include that.
If you want to have this functionality on a Nexus running stock Android you might want to try these two applications, I have used them both, and they are quite stable and useful.

Is there a way I can get it to not upload videos from my phone (or have it ignore things in a certain directory on my phone)?<issue_comment>username_1: I don't think there is any way to stop the Google Plus from auto uploading video if you have instant upload turn on.
The work around I can think off is to use a file manager like "Astro" to move all your video file from /DCIM/Camera folder to a different folder in your sdcard. I believe Google Plus will ignore the folder outside of /DCIM/
EDIT: Re-read your post, looks like you were uploading video from your PC to your phone which you probably just placing those under some folder in sdcard.
You can try this app [StudioKUMA .nomedia Manager](https://play.google.com/store/apps/details?id=com.studiokuma.nomedia) and set the folder that contains video with .nomedia and perhaps the entire folder will be ignore by Google+

What you should actually do is to repair the phone, it costs a certain amount, but at least you get the problem fixed by professionals and can take preventive measures to prevent this from happening again.
1. To repair, you can use [Nexus S Power Button Repair](http://mobiletechvideos.mybigcommerce.com/nexus-s-power-button-repair/) or other near you.
2. As a preventive measure, to avoid degrading the power button, you can use an app to lock/unlock the phone. With it, you'll give less use to your power button, and in turn it may last longer.
Even if it gets broken again, with an app, you still have alternative methods of controlling your phone (lock/unlock).

What you could do is turn the screen brightness down all the way, and then use an app like [Screen Filter](https://play.google.com/store/apps/details?id=com.haxor&hl=en "Screen Filter") to make the screen even darker. At it's minimum setting, this will almost have the effect of turning the screen off, while letting everything still run.

2012/08/15 | 750 | 2,855 | <issue_start>username_0: I'm trying to install the google-adb-drivers.zip file ([obtained here](http://dottech.org/downloads/google-adb-drivers.zip)) on a Windows 7 64-bit system. The phone is the Nexus S 9020T. USB connectivity works correctly for file transfer mode. When I enable debugging, I expect to see "Nexus" appear under "Other Devices" in Device Manager, but it doesn't. After checking USB Debugging under "Developer Options" in the phone, the computer makes the USB disconnected sound.
I was able to load the drivers on a different Windows 7 32-bit system, but that's not the system I want to use.
Why is the debugging port not being recognized on the 64 bit system?
I saw the [other post](https://android.stackexchange.com/questions/16336/google-nexus-s-usb-drivers-for-windows-7-64bit) with a link to download the SDK, but I also would like to avoid installing the entire SDK unless absolutely necessary.<issue_comment>username_1: You should get the proper USB driver via the SDK Manager (which is the the tool you will run when installing the SDK).
The first step in installing the SDK, is starting the 'SDK Manager", and downloading an Android API package (ie. the code to develop for a specific API)
In the list of options, is an 'Extras' section - that contains the official USB driver for Android developer devices (of which the Nexus S is one). Download that driver for best results.
You won't need to install the whole SDK using this method, but will need to start down that path, in order to get the proper driver.
Good Luck.

Might be worth a shot to try that instead.
The alternative is to try this other USB download from the same site [here](http://developer.android.com/sdk/win-usb.html).
The final [linky](http://www.androidsim.net/2009/08/how-to-1-how-to-install-usb-driver-on.html) to an alternative site to get this to work can be found here which comes with a edited minimal SDK download purely to get the drivers to work.
If not, then why not temporarily download the whole SDK (*have no choice here and is totally unavoidable*) and just extract the USB drivers from there and wipe the SDK instead, and if you do, be sure to make a backup copy of the USB drivers! :)
Upvotes: 1 <issue_comment>username_3: Download the proper SDK API for Nexus and more-over you have to download the proper driver, if you have already installed the driver please uninstall it and then reinstall the driver, then it will work fine as I faced the same problem a couple of months ago.

2012/08/16 | 1,285 | 4,964 | <issue_start>username_0: I have a Samsung Galaxy S2 and my friend has an iPhone.
I have downloaded and installed the Norton Anti Virus app. I am at a loss to understand why iOS seemingly does not need protection as such. A smartphone, I have been told, is no less than a computer (even better, faster etc.), so need to be safeguarded.
Or is there another reason why iOS has no AntiVirus apps while Android does?<issue_comment>username_1: This has some reasons, let's try to sum them up:
* Android has an open app market model (there's the more or less curated Play store but you can install apps from other locations (3rd party markets or self built/downloaded))
* Android may also not need AntiVirus apps (most problems come from pirated rogue apps with added *value* piggybacked)
* iOS has a strictly curated app store and you're not allowed to bypass it (unless you don't jailbreak your device but Apple so far ignores the existence of jailbroken devices)
* Apple doesn't allow AntiVirus apps into their app store (they don't grant the necessary privileges to 3rd party apps and ignore the existence of jailbroken devices)
* AntiVirus vendors want to create a market for mobile AntiVirus solutions
* Apple denies existence/possibility of malware for their platforms as long as it's [possible](http://www.itproportal.com/2012/06/26/apple-removes-no-pc-viruses-claim-from-its-mac-os-x-website/) (for PR reasons)
To sum it up: Android is more open than iOS and lets AntiVirus vendors jump in while Apple denies them access to their app store.
Upvotes: 4 [selected_answer]<issue_comment>username_2: The entire philosophy of the two competing "App markets" are different.
The Android Market, known as **Google Play**, allows any submitted application. Apps aren't *really* checked or pre-screened, they're simply submitted, and anyone can download them. Any kind of app can be submitted to the Play store, even one that hooks into the core operating system.
This is a double-edged sword, as a developer can write a malicious app, one that steals your data, disables your phone, and other nasty things. Usually, only when enough people complain will Google take notice and remove an app.
While Google *does* take some measures to protect its users, the protections applied are automated, and apps sometimes do slip through. *(See [Bouncer](http://googlemobile.blogspot.de/2012/02/android-and-security.html). Stats show that it has been somewhat successful).*
---
Apps submitted to the **iOS App Store** have to go through a strict vetting process. Apple hires testing teams. They will manually inspect your app, to make sure it does what it says, without bugs, doesn't use private or secret functions on the iOS device, and so on. Apps are run in a *sand box* and cannot make any major changes to the way the device works. Since all apps are pre-screened before they are posted on the App Store, there is almost no chance of an application being malicious (virus, data stealing, etc).
---
As for whether or not you actually *need* an anti-virus app, well, [this question](https://android.stackexchange.com/questions/341/is-an-antivirus-really-needed-for-android) may help answer that. Personally, I don't think viruses are a massive threat yet, and, although they may be later, I don't think it's worth the potential performance hit. Besides, [Bouncer](http://googlemobile.blogspot.de/2012/02/android-and-security.html) can help with most malware.
I'd be more worried about data-stealing apps, especially if the app holding sensitive data isn't sufficiently protected. [Last year, Skype wasn't encrypting its contacts database](http://www.androidpolice.com/2011/04/14/exclusive-vulnerability-in-skype-for-android-is-exposing-your-name-phone-number-chat-logs-and-a-lot-more/), and malicious apps were able to simply read the data. This has, since, been patched.

Each iOS app is lives in a Sandobox and can't access other apps and services. iOS apps can't run forever in a background instead they are hibernated to ensure good battery life. Also if you use passcode your data is encrypted. iOS built with security in mind and doesn't need antivirus.
There's innovative iOS mechanisms (Extensions, Action Sheet) which allows apps to work together and share data. This features are safe from viruses because:
* Each interaction activated by the user, not OS.
* This mechanisms are also sandboxed.
Each antivirus truly acts like a virus, it just works on your side and because viruses is not possible with iOS, antivirus also can't exist there.
Android works like PC where any process can run indefinitely and can access any part of the File System / OS. Android is improving encryption but even the latest Android version [4 years behind from iOS.](https://blog.cryptographyengineering.com/2016/11/24/android-n-encryption/)

My home wifi and the phone's 3G networks are with different providers. Obviously, my phone switches to the home wifi network automatically when I am at home.
My question: Is it possible for my 3G network provider to see/track my wifi usage and bill me accordingly (as if I am using the 3G network) because everything goes through the phone that is on their network?
I am new to smart phones so please bear with me. My monthly 3G data download allowance is only 150 MB but my home wifi came with 5 GB.<issue_comment>username_1: Of course not. Your WiFi will go through your WiFi chip to AP and to some other ISP. There is no connection with 3G just like you can use WiFi even without SIM.
But your carrier can(though highly unlikely) use some tracking program to track you and find what you are doing. Even if they do, the WiFi usage won't be counted as 3G.
One advice I'd like to give you is sometimes you think you're on WiFi but due to many reasons you might not be connected to WiFi and you might be browsing over 3G. So just keep an eye for that.

To be sure you are using only WiFi connection, you should specifically turn off the mobile data connection (in that case you will have no connection if you lose the WiFi connection, instead of switching automatically to mobile data connection without you noticing.)
There are [plenty of widgets out there](https://play.google.com/store/search?q=mobile%20data%20widget&c=apps) that can make it more convenient to turn on/off your data connection.

This was quite clear in Gingerbread and older versions of Android, which removed the mobile data icon from the status bar when Wi-Fi was in use. From Honeycomb onward, the mobile data icon may remain on screen when Wi-Fi is active.
If your carrier/handset manufacturer hasn't customized the firmware *too* much, then (on ICS and later) the active data network will be blue, while the inactive data network will be white. (I don't have one handy, but I believe on the S2 they always appear in white, which is confusing. Still, Wi-Fi overrides mobile data.)

I referred to [Where is the background image saved?](https://android.stackexchange.com/questions/18450/where-is-the-background-image-saved), but my `/data/data/com.android.settings/files` folder is empty (I do have my file browser showing hidden files). It was confirmed in that question that ICS stored it in that location, but did Jellybean move it to a different place?<issue_comment>username_1: The wallpaper was in
```
data/data/com.android.settings/files/
```
on previous versions of Android. However it appears that it was moved as part of the multi-user preparations. The current location is
```
data/system/users/0/
```
The file is conveniently called wallpaper and it is a png file.

2012/08/16 | 423 | 1,593 | <issue_start>username_0: I have a Samsung Galaxy Ace with its official CyanogenMod nightly build. And suddenly, it doesn't "see" my pictures, videos or music files. They don't show:
1. while selecting a notification/ring tone & default music player,
2. while viewing pictures in QuickPic or the default gallery, and
3. on Go Launcher Ex's videos and music finder feature.
However, ES File Explorer, the default File Manager, and PowerAmp clearly show the said types of files. I've done a NANDROID backup, wiped the partitions then restored the backup, still no go.<issue_comment>username_1: Ah, cripes. I don't know what on Earth put this `.nomedia` file on the root of my SD card. Problem fixed.

I then renamed the folders back to "DCIM" and "Music". It took 48 hours of online searches, learning about the 'emulated' folder etc - but this was the simple solution. I guess it reindexes the folders and makes them be found again by the appropriate apps.
Hope this helps.

2012/08/16 | 1,208 | 4,599 | <issue_start>username_0: Is there some way to get a lock screen whose PIN pad changes number layouts every time it's used? It seems like a very basic way to thwart smudge attacks and yet my (broken?) google-fu can't find any implementations.
I'm using 2.3 Gingerbread, would prefer solutions not involving rooting/flashing new ROMs if possible.<issue_comment>username_1: That is a very interesting question. I am not sure if this can be done, to scramble the keypad's number layout every-time on unlock to force you to slow down.
You've pointed out the weakness in the security - smudges on the touchscreen; the only thing that I can think of is this - wipe down the screen each time... now you may get funny looks from others, akin to taking off the glasses each time and wiping it cleanly to "see" again if you get my drift.
I would not be surprised if there's a soft keyboard layout that appears at random intervals but I suspect its never thought of as it would drive users batty especially when texting.
The lock-screen's pin mechanism is in-built and to override that mechanism requires going down the unofficial programming interface that does not have the approval from Google's Android development aspect. Almost bordering on using malware techniques to achieve it.
The other thing I can think of is to use a screen protector, in that way, the smudges will show on it but not on the actual touchscreen. Despite saying that, one could theoretically sprinkle a bit of powder on the screen and gently brush it away to see where the fingerprint is on but that's going OTT on the other hand, that is, if you watch too much NCIS... :)
My suggestion - in the case of pattern unlock, do not allow "Use Visible Pattern" or "Use tactile feedback" under Settings > Location & security settings, to minimize breach.
But however, your question is a worthy +1 from me from a security viewpoint.
**Edit:**
Just an afterthought after exchange on chat, it is quite possible in theory, to use a custom keyboard that is tied specifically to password input, the ones that shows an asterisk in place, and just randomize the keyboard layout with letters, numbers re-positioned at random intervals but that could have an adverse side effect, as in "darn it, now I have to be extra careful to, not to go too fast!" or "darn it, one thing to do - uninstall it as tis annoying!"

Looks like this was [raised as an enhancement request](http://code.google.com/p/android/issues/detail?id=10496) two years ago, if that means anything. I found two apps that seek to address your concern:
* [Whisper Systems](http://whispersys.com/screenlock.html) has a different method of working around smudge issues by asking users to wipe over the smudges they just created.
* [Number Track Lock](https://play.google.com/store/apps/details?id=jp.jmon.matrixlockscreen&hl=en) advertises the exact functionality you're looking for. This is a paid app that has mediocre reviews, so proceed at your own risk.
Neither of these to me are a perfect solution. I'd love to see this built into Android - perhaps you can find a ROM with something like this baked in?

I just switched to a 16GB Samsung Galaxy J3 (much pricier than my trusty K7), and it doesn't have a randomized PIN.
I checked online, and the LG V10 and LG Lancet have it, too. Maybe it's just an LG innovation.

2012/08/16 | 1,131 | 4,581 | <issue_start>username_0: I have a Samsung Galaxy S2 that has some problems with the GPS:
If I use internet my navigation works but when I turn the 3G off, GPS does not work.
Do I need internet/3G to use GPS?<issue_comment>username_1: In short: GPS works without an active connection, it's completely passive.
GPS has however an addon feature called A-GPS (assisted GPS) which speeds up the startup (*time to first fix*) considerably. It basically warms up the receiver with GPS status data such as time, coarse location and most of all GPS satellite orbit location data (ephemeris data download). Everything of this is also included in the GPS signal but a cold start needs longer if the receiver needs to fetch it itself. With A-GPS this data is downloaded from the internet and fed to the receiver.
Note: The A-GPS data is good for some days but deteriorates over time until the phone needs longer to (once!) cold start again (or a internet re-download is necessary). You can trigger a manual redownload with some apps, for example [GPS status](https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2).

GPS itself does not require Internet connectivity. However, many navigation apps (e.g. Google Maps or Waze) require an active connection in order to access map data on-the-fly, compute directions, look up traffic details, search for points of interest, etc.
There are other (usually paid) apps that don't require Internet connectivity for navigation because they provide this data as a separate download. Directions, turn-by-turn navigation, POIs, etc. can then be accessed from data that is stored on SD Card, while the device is offline.
In both cases GPS is only used to place your current position on the map.
Upvotes: 3 <issue_comment>username_3: Basic Concepts
--------------
You are confusing two different concepts: "GPS" and "Navigation", that are used for two distinct scenarios on your device.
GPS is used to pin-point your location in the globe. Navigation is used to plan and track your movements from point A to point B.
While Navigation may depend on 3G or Wi-Fi to access the internet and retrieve maps and other information as to graphically present your location in relation to the designated route, GPS doesn't use the Internet, it works communicating directly with antennas and in turn with satellites to ascertain you global position.
Phone Settings
--------------
There are two phone settings regarding GPS, one is the GPS on/off toggle, the other one is the A-GPS ([Assisted GPS](http://en.wikipedia.org/wiki/Assisted_GPS)), that actually relies on Internet Connectivity as to provide faster and some times more accurate results:
* Tap your device "menu" button;
* Tap "Settings";
* Tap "Location & Security":
+ "Use GPS satellites" - When locating, accurate to street level:
Tap to apply the green tick as to have the regular GPS method available.
+ "Use Quick GPS" - Use server to assist GPS (check to improve GPS performance):
If the GPS option is active, you can tap to activate this option, improving GPS accuracy, but keep in mind that this only works with a data plan, as it uses network resources to assist ascertaining your Geolocation.
Navigate offline
----------------
If you need navigation capabilities while offline, you can use an app that relies on maps downloaded to your phone. Personally I'm happy with [Navfree: Free GPS Navigation](https://play.google.com/store/apps/details?id=com.navfree.android.OSM.ALL) by Navmii available from Google Play Store. I've downloaded some maps, for Portugal, around 90Mb, but afterwards I'm fully capable of navigating without any internet connection.

2012/08/17 | 1,013 | 4,138 | <issue_start>username_0: As far as I understand it, it is a big system file that apparently controls a big part of the phone. I am interested because I wanted to do some themeing and so far I had edited SystemUI.apk, but if I ever ran into any problems (and being a beginner that was bound to happen) nothing seemed to happen other than the fact that I lost my notification bar.
Problem is, I have heard of some people who touched framework-res.apk and they wound up not being able to even boot their phone. I decided before carelessly poking around with something that could potentially soft brick my phone, I would like to learn a bit more about it.
So what exactly is framework-res.apk? What is it used for? What does it control? Where do we visually see its use? What could potentially happen to my phone should something go amiss with framework-res? Anything else I should know before poking my nose where it shouldn't be?<issue_comment>username_1: `Framework-res.apk` basically contains the elements of the Graphical User Interface for the phone. This file is available at `/system/framework/framework-res.apk`.
Poking in this file would mean changing the complete look and feel of your device. Since it is the main element of your screen, replacing it directly by pushing it through ADB would lead to soft-brick. Therefore, this apk should carefully be modified and replaced using the recovery module of the phone.
Check this link for details on the same: [Modifying the framework-res.apk (Theming the UI)](http://www.apad.tv/apadforum/entry.php?199-Modifying-the-framework-res.apk-%28theming-the-user-interface%29)
Upvotes: 3 <issue_comment>username_2: From my coding experience, I can say the following as my understanding:
If you are familiar with application development terminologies, this framework-res.apk is just a resource library. Continuing with that assumption, other modules, libraries depend on this file to get images, sound etc. For example the boot animation sound is embedded in this file. Every resource will generally be given an identifier through with the other modules load and they will just assume or take it for granted that such resource will be available in this file.
Generally there will be a manifest file which will index all the resources (images, sounds etc) against its identifier. The code segments that maps the resources against its identifier and that fetches the requested resource will be compiled against one platform/version/library and hence tweaking and recompiling if not done carefully will make the framework-res.apk incompatible with its consuming modules. Depending on how things are implemented, you would get away with an error, but developers can't expect to verify everything and they have to take certain things for granted (like presence of a resource as it is they who had planted it). Hence usually the consuming module freezes and hence the whole phone appears to be frozen as system modules as well depends on this apk.

2012/08/17 | 938 | 3,472 | <issue_start>username_0: Usually, the guides for getting root or re-installing the OS on an Android device (I have a Samsung Galaxy S, which I'm mostly inetersted about) tell to flash the device from another computer through the USB cable.
Is it in principle possible to perform such modifications without using the USB cable (and another computer)?
Perhaps, by putting a file with the other version of the kernel/OS soemwhere on the device, and booting it in a special mode?
Imaginne the situation: I took the Samsung Galaxy S (and a laptop), but no USB cables, and went away from the civilization. Now it turns out that to use some of the apps I would like to use (like SSH server frontends for Android) I
* either have to re-install the Android OS (because they want a newer version; so I'd use CyanogenMod or Replicant because there are no offical upgrades from Samsung)
* or have root (because they don't want to work without root).
Can this be done without a USB cable?
* (Of course, there is another good solution in this situation: take the source code of those apps, and fix them so that they will work for me, re-compile and install them.)
(AFAIU, after I have full (root) access to the device, I can re-install the OS without a cable and another computer: for example, I have another device that was supposed to work under Android -- Toshiba AC100, but after I installed Ubuntu 12.04 on it by flashing the device, I must be able to re-install the kernel from inside the OS -- there is a "flash-kernel" utility in Ubuntu.)<issue_comment>username_1: I guess there must be a backdoor for this because I've read in a news article that it will be possible to upgrade (officially) the OS on Samsung Galaxy without connecting it with a USB cable to another computer **by means of a new "Kies" app from Samsung**.
So, it's possible for an app (in this case, at least the Kies app) to re-install the OS. But this backdoor might be well-protected (requiring cryptographic signatures from Samsung perhaps -- just a guess).
And the article told that one should install the "Kies" app (if it is not present) through the "Samsung apps" app. (I haven't tested this myself because I have been using the device without a SIM-card, but the "Samsung app" app wants a SIM-card...)
So, it's possible to install an app that will be able to re-install the OS. But this backdoor might be well protected (perhaps, only an app from Samsung can do this).

Google is certainly able to do so, if you are using a Google Services enabled device (usually the ones with "by Google" on the back). But basically every hardware/software manufacturer, whose parts are placed within smartphone (or traditional mobile phone), is able to install backdoors in his products, which could by used third parties to manipulate the device. Either because they bought this access or because the manufacturer is forced to, for example by a (secret) government regulation.

Usually you will see visual feedback about the installation process, at least until it's running. But the notification about the new app stays in the notification bar. But no one can rule out that there is a silent install method too.

Android apps are able to activiate the microphone if they have the permission to to so. But if the app came with a silent install method, who knows if the permission for the microphone was also silently given?
And now, how can I protect my privacy?
--------------------------------------
As soon as you buy a piece of hardware/software without having the ability to verify the hardware and software components for surveillance backdoors, you are lost.
But there are alternatives. There have been attempts to create open source [hardware](http://en.wikipedia.org/wiki/Open-source_hardware) and software for smartphones. Therefore allowing you to review the components for unwanted modules. See for example [Opoenmoko](http://wiki.openmoko.org/wiki/Main_Page).

Thing is, no one really know for certain if they actually did, as the security world got "excited" about it and started to slam-back on the manufacturers - Apple, HTC, Samsung, Sony, to name but a few. And exposed the ruse behind it, all of a sudden that hype fed its way into the Android world, and guess what happened - an app appeared on the Google Play Store, [Carrier-IQ detector](https://play.google.com/store/apps/details?id=com.lookout.carrieriqdetector).
What I was emphasizing, is how the paranoia made its way into the norms of human emotions - yes, a lot of people were really mad and demanded to know - was there a breach of privacy?
By the way, if you look on the main Carrier-IQ site [here](http://www.carrieriq.com/), there's a ticker that states as of now, 147,918,175 handsets deployed.... (Ok, am not really sure if they are trolling us with that ticker but questionable as it was stated on the wikipedia that is "*deployed in over 150million devices*" heck it aint even there!!!)
Yes it is quite possible that there are back-doors available to do just that kind of thing, and is commonly associated with stock ROMs straight from the factory! Zte had one, and was reported a while ago and its publicly available on [pastebin](http://pastebin.com/wamYsqTV). For the sake of historical information, I'll quote it here in case it gets lost.

It does show one thing and one thing alone, Stock ROMs! All too often people can be naive in thinking that just because its "Stock ROM", it does its job.
Now, not to induce fear or paranoia into anyone, which I certainly would not wish to do so, it helps to have a cool collected thoughts about this.
The dose of reality will hit home, once you realize how, custom ROMs have a better advantage over stock ROMs, they are compiled from source code and is publicly available, such as CyanogenMod, AOSP, CAF, AOKP; rest assured, you will be equally better off with those ROMs in the long term.
**Why?** For the most part those custom ROMs would be rooted anyway, which will enable you as a user, to have a tight rein on the handset **in the way you want it**, not some fancy-schmancy stock skin on top of the ROM, such as HTC Sense, Samsung TouchWiz, Sony TimeScape etc. And if the developer of said ROM is trusted to be good, i.e. good community feedback, then yes you would be pretty safe.
What you can do to re-inforce the belief that a custom ROM is better than stock any day is this, knowing that the ROM is rooted, you can use Droidwall/Hi-Surfing, or another type of firewall, to block access to those "sneaky" apps like that. That will put in a level of assurance, but having said that, its not about justifying why having a rooted ROM in the first place, rather its, to empower yourself over the handset and use it in the way you want. If you don't like an app, uninstall it, if an app requires root - then so be it.
It does make you think and ponder for a bit in why carriers would rather have you to be stuck with a stock ROM, and a locked bootloader i.e. "rooting will void the warranty", "unlock the bootloader - you're on your own", but there's always two sides to the same coin, if anyone can get their hands on a handset, and unlock the bootloader, it will simply factory reset and wipe the data upon unlocking and reboot!
So you can see how, from a security viewpoint in what's going on and the decisions involved. I know, when I made a ROM for Zte Blade, I was trusting that the source does not have any malicious code, well, it was coming from AOSP source on google and yes, its rooted, and users feedback is good.
There's a lot of thought in what was said, and yes, that kind of thing can be blocked - If you want to be really secure - block the following under Droidwall here,
* Download Manager, Downloads, DRM protected content storage, Media Storage.
* Google Services Framework, Network Location, Google Calendar Sync, Google Contacts Sync.
* And finally, block the Linux kernel as well.
With those criteria selected, you will most certainly not be able to download remotely nor sync either. Also, pay attention to the permissions that is asked for by the app on Google Play store, be prudent and you will have nothing to fear.

Mobile providers can also do this as long as their Trojan app comes pre-installed with device. They can push and install an app to listen your voices.
How to block it?
* Root your device and hunt down all apps from mobile providers which could do such nasty things. Google can help. Either remove them from system or block their access to internet using Firewall (there're many firewall apps in Play Store).
* Flash a fresh new custom ROM like CyanogenMod etc.
Upvotes: 2 <issue_comment>username_4: Yes. CarrierIQ, Smithlogger, HTC Logger, and a couple of other things are installed onto the device by the carriers.
iPhones are stuck with CIQ, with nothing more than the mere delusion it isn't there or that they *can* get rid of it when, in fact, they *cannot*
However, you can get [this](http://androidsecuritytest.com/), which is more helpful if you're rooted, but even without root privileges, it can point you to the opt-out screen for any logging service that may be on your phone.
Furthermore, all this news talk about malware on Androids is crap.
You have to install said "malware" - but the "malware" barely even exists.
So long as you pay attention to what permissions each app you are installing has, you have no chance of anyone leveraging your phone to spy on you.

Yes! It is possible to remotely install apps on your Android phone without your consent. Most of the devices are vulnerable to attacks due to vulnerabilities found in core Android framework.
For an example, Stagefright vulnerability found back in 2015 July puts about 95% of all Android devices in danger. This vulnerability is activated when Android process a malformed multimedia files on the device. For an example an malformed image you receive as an MMS could trigger the Stagefright vulnerability

1. Do not click on any links received from people you don’t know.
2. Install a virus scanner and keep it up-to-date.
3. Do not leave your phone unattended. Always have a phone locked with a PIN or pattern

2012/08/17 | 380 | 1,462 | <issue_start>username_0: I have a Samsung Galaxy S with Android 2.2.
I have read that now there is a "Kies" app available from Samsung which would allow to upgrade the OS on the phone without connecting it with the USB cable to another computer.
That article said I have to install it through the "Samsung apps" app. So I started it, but it said it won't work without a SIM card.
But I intended to use only WiFi, I don't need the SIM card and the mobile connection.
Why this problem? Is it solvable (without a SIM card)?<issue_comment>username_1: There is probably no Kies app for Android, as @onik notes in the comments.
I was mistaken probably when I thought that there is one.
Upvotes: 1 <issue_comment>username_2: No, the Samsung apps market won't start without a SIM card, because the card is used to determine the country of the user.
There is an App called "Kies Air" which allows you to connect your device to the Kies App installed on your PC over WiFi. But I doubt that you are able to upgrade the OS this way. It's more meant for synchronization (calendar, email, ...) use.
IMHO you need a USB cable to update the SGS, either with Kies or [Odin](https://android.stackexchange.com/questions/tagged/odin)/[Heimdall](https://android.stackexchange.com/questions/tagged/heimdall).

I don't understand what this means. Which recovery to flash? How to do this? (With a USB cable, or it can be done by some manipulation with the phone alone, without connecting it to another computer?)<issue_comment>username_1: From the link you provided, you've problem to make ROM Manager work. Use this app. ROM Manager flashes the CWM recovery from within the app.
There's no need of another computer at all...
Upvotes: 2 <issue_comment>username_2: I have just a few hours ago flashed ClockworkMod Recovery on my Galaxy S in order to switch from stock ROM to [cyanogenmod](http://www.cyanogenmod.com/). Simply follow the instructions from the [official Samsung Galaxy S Full Update Guide.](http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S%3a_Full_Update_Guide)
The [relevant section about flashing recovery](http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S%3a_Full_Update_Guide#Installing_the_ClockworkMod_Recovery) contains the steps you need to follow. Make sure to read the Note at the end of the section if the first kernel doesn't work for you (it didn't work for me).
Upvotes: 2 <issue_comment>username_3: The general consensus is there's usually different partitions available:
* system
* data
* cache
* boot
* recovery
When a guide says to flash "partition" where partition is one of the above, then that implies transferring the contents destined for the partition. The mileage will vary depending on the handset/manufacturer as not all of them actually have implemented partitions like the above.
Usually it can be done with using the cable plugged in and using fastboot.
For example:
To flash a kernel onto the boot partition one can undertake it like this:
```
sudo fastboot flash boot boot_image_file.img
```
followed by:
```
sudo fastboot reboot
```
Likewise in the OP's case, its referring to the recovery partition.
```
sudo fastboot flash recovery recovery_image_file.img
```
I would be wary about using ROM Manager to do this for you without using a computer; Have got bitten by it, and found that it can sometimes, be incorrect with regards to using recovery i.e. ClockworkMod Recovery, it was so convinced that I had a very old version of CWM, when in reality, the latest was installed; end result, I messed up the recovery and threw away ROM Manager as I preferred to do it on the computer - less errors and that the human checking is in place.

2012/08/17 | 1,048 | 3,947 | <issue_start>username_0: I recently bought a 7" Android ICS tablet as a gift for a friend. Unfortunately it's not a Store supported device, so I can't download from the Store.
There are a number of sites that allow you to download APKs, but most of the apps I want to download aren't available on them. I have a 10" tablet that IS supported and has a large number of the apps I want to provide to my friend. Is there any way to get at the APKs on the 10" tablet (without rooting it) so I can copy them to, and install them on the 7" - using the provided app installer?<issue_comment>username_1: Try with a [file browser (Astro)](https://play.google.com/store/apps/details?id=com.metago.astro&hl=en) or something like that to browse on your tablet and then you'll find the apk's if you search good.
But it is not sure they will work correctly or possible to transport them. But you can always give it a try.

Upvotes: 4 [selected_answer]<issue_comment>username_3: Best choice for this is IMHO [AppMonster](https://play.google.com/store/apps/details?id=de.android_telefonie.appmanager), which backs up your `*.apk` files to sdcard. This version is free but somehow limited; the real power comes with its payed version, [AppMonster Pro Backup Restore](https://play.google.com/store/apps/details?id=com.think_android.appmanagerpro) (~EUR 3) -- which not only adds batch-mode for restore, but also automatically backs up all new installations/updates, while letting you define how many generations you want to keep and (at least this was on the roadmap) even "pin" a version you want to keep "forever".
An added plus is that it also shows whether an app has ad modules hooked in (e.g. AdMob), if it supports App2SD, or if it is already installed on SD:
  
For me, it is the ultimate tool for this goal -- saved my ass a couple of times, when some app-update introduced a bug, or ripped away a feature. The only thing I miss here is it cannot backup the apps' data -- but that's a thing impossible to all non-root apps (for this, I use mentioned [Titanium Backup](https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup) -- but that's not topic of this question, and thus just mentioned for completeness).
To sum up: *AppMonster* would solve your problem with getting the `*.apk` files to the sdcard for transfer -- and even offer you features you surely will use even after completing that job. Moreover, if you use the Pro version, the sdcard copy will be done automatically for you, saving you some manual work.

**How can I add and edit bookmarks within a PDF on Android?**<issue_comment>username_1: Direct editing of PDF content is something hard to achieve. As far as I know, the only solution for this is [Qoppa PDF Notes](https://play.google.com/store/apps/details?id=com.qoppa.activities.notes). However: bookmarks (create & edit) and annotations (also create & edit) are possible.
The best eBook-Reader on Android, also known as [Moon+ Reader Pro](https://play.google.com/store/apps/details?id=com.flyersoft.moonreaderp), supports this not only for PDF (Pro only!) -- but also for EPUB and other formats (Pro & Free). Another popular solution (PDF only) is [ezPDF](https://play.google.com/store/apps/details?id=udk.android.reader).
For more solutions, you might consult the Playstore, and check with the descriptions. The keywords are "bookmark" and "annotation".

If you are using Adobe reader, tap the screen and the tap the icon down on the lower right that looks like an open book.
Then, tap the "bookmarks" tab.
Press and hold on the bookmark you wish to edit. You will be given the option to edit the name of the bookmark.
To add a new bookmark:
Tap the screen when you are on the page you wish to bookmark.
Then, tap the bookmark icon on the top near the right. This icon is flat at the top and is more tall than it is long. The bottom of the icon is like a Chevron or upside down v.
To access your bookmarks:
Tap the screen and then tap the icon down on the lower right hand side that looks like an open book.
Then, tap the "bookmarks" tab.
Tap the desired bookmarked page or edited bookmark title to view.

Alternatively if you are using WPS:
tap the screen when viewing a pdf document and select the view tab on the bottom right of the screen.
Bookmarks are on the left (you may need to scroll down a bit). There is an add bookmark icon on the far left and there is a bookmarks icon that will list existing bookmarked pages that you can select.
The bookmark function in both of these viewers is a lifesaver when doing math homework to skip to the answers for odd numbered problems in the back or at the the end pages of the textbook file.

2. Tap the entry to chose/arrange tiles
3. if "WiFi Hotspot" isn't shown on a tile:
1. tap the `+` symbol
2. scroll to the end of the list
3. tap the corresponding entry to add (WiFi-Hostpot)
4. optionally: move the tile where you like to have it
Now, toggling the hotspot is as simple as
1. pull-down the notification bar *from the right corner* (this should immediately show Quick Settings)
2. if Quick Settings aren't shown (but your notification area is), tap the top-right corner to switch over
3. tap the hostpot tile
Some ROMs (such as CyanogenMod) even allow you to have the very same stuff "synced" to quick toggles placed on top of the notification area, for even easier access.

2012/08/17 | 1,407 | 5,615 | <issue_start>username_0: I have recently installed a custom ROM and cannot find the Play Store. It seems like all apps that belong to Google are missing.
**How can I install the Google Apps Package (Play Store, ...) on my Android device?**<issue_comment>username_1: Background
==========
Only Android devices that are licensed by the Open Handset Alliance contain the so called Google Apps. Usually people associate apps like Google Maps, Google Play Store, etc. with Android, but because of the open-source nature of Android, manufactures can sell Android devices without Google Apps and therefore avoid to pay the license fee.
Custom ROMs
-----------
At first cyanogenmod shipped its ROM with pre-installed Google Apps. In September 2009 the founder of Cyanogen received a cease and desist letter from Google, demanding that the Google Apps not be included in the team's ROMs, since the ROM could be ported to devices which are not licensed to have the Google Apps. In turn, that would bypass the requirement for the devices to be licensed. For a few days, development on the ROM ceased, there were outcries from Android users all over the Internet, and many bloggers suspected Google had just shot itself in the foot.
Eventually, an alternate method was found, whereby Google Apps are not included in the ROM proper but the Google Apps which came with a device would be backed up by the device's custom recovery or another app, and then re-installed onto the device once the new ROM was flashed. This would therefore "Google-ify" one's ROM.

How to install Google Apps?
===========================
Generally speaking:
First download the package corresponding to your version of android. Currently (november 2015), there are several "distributors" of Gapps available. Each typically offers a set of packages per android version, each package with more content. The apps in the packages range from a lite package with the basic apps (~100MB) to all of googles apps(200+MB). The applications themselves are untouched.
* If you don't want to or cannot root your device:
1. Flash the Gapps ([Google Apps Package](http://wiki.rootzwiki.com/Google_Apps)) zip package with a custom recovery.
You may first need to flash a custom recovery (like CWM or TWRP) using a PC tool such as Fastboot or Odin/Heimdall. This flashing in turn may require an unlocked bootloader on the phone.
* If root is not a problem: ([See if you can root the device](https://android.stackexchange.com/questions/1184/how-do-i-root-my-device))
Some stock recoveries will let you "update with adb". Just install adb, then adb command to install is:`adb sideload gapps.zip`--assuming the package is in the adb folder and is called gapps.zip
You may also install a custom recovery like in the unrooted case.
Root typically allows android apps to flash a new recovery (i.e. without a pc).
OR
Install a ROM with the Google Framework, if it exists for your device. Though many ROM developers have followed CyanogenMod's example of separating distribution.
If you flash a Gapps ROM, it may be possible to re-flash with another non-Gapps ROM afterwards while retaining the Gapps. This assumes the android versions are compatible.
Most users capable of flashing a ROM will be capable of flashing Gapps separately.

Upvotes: 3 <issue_comment>username_3: I wanted to add to this as there is no link to where to get the GApps. The newest group is Open Gapps. These do not work with EVERY custom ROM, but the vast majority (and those based on AOSP should work).
Open Gapps: <http://opengapps.org/>
This site is awesome because when loaded you get a basic UI with a couple selections that allows you to specify what you want (some packages have more google apps, others have less), they even have an option to include the Aroma Installer version which when flashed in TWRP or clockwork will actually bring up a menu system which you can tap to make selections of which apps and which settings you would like at the time of the install! Of course it is large as it includes everything, but it can be nice to be able to customize the gapps install as you are installing it (and yes it has the ability to save your selections for future installs at the end of the setup UI it will ask if you want to save your selections. If you do future installs it just opens the UI and you tap to load the saved file and done).
Open Gapps has help ?s all over and documentation on their site to help you with many questions.
Cyanogen MOD has their own version of Gapps (page lists gapps packs for every version of CM ROM from CM4+ on this page. Note that as of CM11 CM Roms can now flash Open Gapps.):
<https://wiki.cyanogenmod.org/w/Google_Apps>
(looks like as of CM13 they have stopped their custom Gapps zips and now fully use Open Gapps).
With these 2 links you should be good to flash GApps with just about any version of Android (I can not account for a severely custom job done by someone that may not work with Open and/or CM GApps, as we know what happens when we assume in the tech world!).

Is there any way to achieve this? My device is rooted.<issue_comment>username_1: Not without a rooted device (or uninstalling/freezing the other apps). If you have a rooted device, you can control each apps network access e.g. using a firewall app like [DroidWall](https://play.google.com/store/apps/details?id=com.googlecode.droidwall.free) or even a more complex security solution like [LBE Privacy Guard](https://play.google.com/store/apps/details?id=com.lbe.security.lite). Both would allow you to say which app(s) may access the network via Wifi and/or mobile network -- so you could even let them all work while connected to the free Wifi provided by the hotel.
If you are not rooted, but your device runs at least Android 4.x or higher, you could alternatively (temporarily) "freeze" (i.e. disable) all apps which should not use the internet.

What's wrong? Can someone help me out here?<issue_comment>username_1: An app must explicitly support App2SD, or you cannot move it to the card. There are several reasons why an app might not support it:
* using widgets (both mentioned apps seem to fall into this category. AK Notepad: "Pin notes to your home screen"; Any.DO: "You can even add our widget to your homescreen")
* running a service
As the sdcard would be unaccessible when connecting to a computer, both things would "crash" (as they could no longer access their data etc.). Of course there's always the possibility the developer simply didn't care -- in which case you should contact him and ask.
Upvotes: 4 [selected_answer]<issue_comment>username_2: There are some factors that may affect this:
1. An app must explicitly declare that it's preferable/possible to be installed on SD card.
>
> Beginning with API Level 8, you can allow your application to be installed on the external storage (for example, the device's SD card). This is an optional feature you can declare for your application with the `android:installLocation` manifest attribute. *If you do not declare this attribute, your application will be installed on the internal storage only **and it cannot be moved to the external storage***.
>
>
>
(Emphasis mine)
2. An app is set to compile using API 7 (Froyo) or lower, which doesn't support installing an app on SD card (even if it's installed on GingerBread or newer devices)
>
> *The ability for your application to install on the external storage is a feature available only on devices running API Level 8 (Android 2.2) or greater. **Existing applications that were built prior to API Level 8 will always install on the internal storage and cannot be moved to the external storage (even on devices with API Level 8)***. However, if your application is designed to support an API Level lower than 8, you can choose to support this feature for devices with API Level 8 or greater and still be compatible with devices using an API Level lower than 8.
>
>
>
(Emphasis mine)
The reasons why some apps are not preferable to be installed on SD card are as following:
>
> When the user enables USB mass storage to share files with their computer (or otherwise unmounts or removes the external storage), any application installed on the external storage and currently running is killed. The system effectively becomes unaware of the application until mass storage is disabled and the external storage is remounted on the device. Besides killing the application and making it unavailable to the user, this can break some types of applications in a more serious way. In order for your application to consistently behave as expected, you should not allow your application to be installed on the external storage if it uses any of the following features, due to the cited consequences when the external storage is unmounted:
>
>
> * Services
>
>
> Your running `Service` will be killed and will not be restarted when external storage is remounted. [...]
> * Alarm Services
>
>
> Your alarms registered with `AlarmManager` will be cancelled. [...]
> * Input Method Engines
>
>
> Your IME will be replaced by the default IME. [...]
> * Live Wallpapers
>
>
> Your running Live Wallpaper will be replaced by the default Live Wallpaper. [...]
> * App Widgets
>
>
> Your App Widget will be removed from the home screen. When external storage is remounted, your App Widget will not be available for the user to select until the system resets the home application (usually not until a system reboot).
> * Account Managers

>
> Your accounts created with `AccountManager` will disappear until external storage is remounted.
> * Sync Adapters

>
> Your `AbstractThreadedSyncAdapter` and all its sync functionality will not work until external storage is remounted.
> * Device Administrators

> Your `DeviceAdminReceiver` and all its admin capabilities will be disabled, which can have unforeseeable consequences for the device functionality, which may persist after external storage is remounted.

EDIT: Using this method requires root access on your phone and also needs your SD card to be formatted to have a second partition on it.

Scenario: I go into a coffeeshop, I fire up my droid, and it says it's on the webs. But as soon as I start surfing it bounces me to the establishment's wifi signon page. I agree, click the button, and (I'm assuming) it sticks the droid's MAC address in a table and lets my traffic through. If I return to said coffeeshop within 24hrs, I'm usually still there.
Problem: My droid is WiFi only, I have no cell contract. So If I walk in and forget to fire up the browser, I won't get any texts or calls.
Solution: Does anyone know of an app that would automate this process? The droid itself will hit the wireless network as soon as it comes within range, provided I've used it before. But then it'd be nice if it tried to fetch a webpage, got redirected, and responded automatically.
Alternative: If there is no such app, would you guys be interested in a free one if I took the time to cook one up?<issue_comment>username_1: There are several Hotspot apps around which can automate this. An example would be [WiFi Web Login](https://play.google.com/store/apps/details?id=com.androidyou.wifiloginnew). I didn't check this one (but used a similar some time ago): As soon as the Wifi comes in reach, your device should connect (provided you did it once manually). If the Hotspot app is running in background, it should pick up from there. You have to record the session once for this to work, it's like a macro-recorder.

I've noticed that when my Google Nexus One phone is showing ~20% of the battery, after using it for a minute or two it completely discharges to 0%. Everything started before two weeks or so. Before that phone was fine, but now if it's showing ~20% of battery, after a few minutes it turns off and when you turn it on, it shows that there are 0% left in a battery and turns off...

2012/08/17 | 818 | 3,205 | <issue_start>username_0: I am looking for typical per app/process resource usage information (CPU, Memory, etc.). This information is often useful to find and identify misbehaving apps.
**How can I monitor and visualize the current resource usage (CPU, Memory, etc.) caused by the running Apps?**<issue_comment>username_1: There are several ways to collect this type of information, I'll be speaking about two that I use on a daily basis as to oversee what's going on with my devices:
Terminal
--------
Using a terminal application, you are able to run Linux commands like `top` or `ps` that provide information about the currently running processes:
* [ps](http://manpages.ubuntu.com/manpages/lucid/man1/ps.1.html)
>
> ps (i.e., process status) displays information about a selection of the active processes.
>
>
>
* [top](http://manpages.ubuntu.com/manpages/lucid/man1/top.1.html)
>
> The top program provides a dynamic real-time view of a running system. It can display system summary information as well as a list of tasks currently being managed by the Linux kernel.
>
>
>
The terminal I most use is called [Android Terminal Emulator](https://play.google.com/store/apps/details?id=jackpal.androidterm) by Jack Palevich available from Google Play Store.
Application
-----------
There are [several applications](https://play.google.com/store/search?q=system%20information&c=apps) with the sole purpose of providing you with real-time information regarding the processes being executed, detailed information about apps and their system resources usage, system logs or system monitoring:
[Android System Info](https://play.google.com/store/apps/details?id=com.electricsheep.asi) by ElectricSheep available from Google Play Store.
This app presents information divided with 5 tabs:
* Dashboard
An overview of you device important information: battery usage; Internal Memory used/free; SDCard size and free space; RAM; etc.
* System
All system information is presented here: OS; Buildinfos; Battery; Memory; Telephony; Networks; Wifi; CPU; Screen; Sensors; Features; JavaProperties; and many more. Just tap over each one to unfold the detailed information.
* Tasks
Shows the total CPU load and CPU load/memory used for each process. You can tap a process to get more details about it; kill the process or switch to the process.
* Apps
List of all installed apps, providing means to stop or uninstall an app. If you tap over an app, you have several options like: launch; Manage; Uninstall; etc. Additionally, you are able to see all the useful information about the package itself and in relation to your system, including all permissions he uses.
* Logs
Provides you with your system logs. If you press "menu" the logs will be saved to your SD card.

2012/08/18 | 435 | 1,732 | <issue_start>username_0: Will the uninstalling of apps leave files in the root (Android's subsystem)?
When we uninstall some program on Windows, it leaves some files along the system, does it happen on Android too? If this happens, would it be be wise to access the root to erase this files and free some space?<issue_comment>username_1: Not in the internal filesystem, but it may leave files on the SD card.
Apps on Android are only able to write on two places within the filesystem
* `/data/data/`
* `/mnt/sdcard/` or `/sdcard`
The `/data/data/` directory gets deleted when you delete the app, so the only place where file cruft can be found is the SD card.
Upvotes: 3 <issue_comment>username_2: That depends, a lot of developers do not properly take care of their associated application's data and may leave them lying around. The Package Manager uninstalls the apps from `/data/data/..../` depending on the package name.
For example, Application MyFooBarApp whose package name is `org.foo.bar.app` then this would be the spot - `/data/data/org.foo.bar.app/` which would have the following:
```
/data/data/org.foo.bar.app/
|
+- databases/
|
+- lib/
|
+- shared_prefs/
|
+- cache/
|
+- files/
```
Those five sub-directories are standard placeholders for the apps to function. And Package Manager will only remove those files and sub-directories upon un-install of said application.
All too often, out of hindsight or bad code, the apps would not automatically clean up after themselves, such as placing temporary files on the `/sdcard` or heavens-forbid, in `/data/local/tmp` which incidentally, is the worst abuse of it as it is world writeable!

please help<issue_comment>username_1: The best you can do is power off the device completely, but do nothing for now, head over to [samfirmware](http://samfirmware.com) and download the appropriate ROM for your region.
Once you do that, refer to the instruction on using [Odin](https://android.stackexchange.com/questions/26869/what-is-the-basic-functionality-behind-the-odin-buttons-checkboxes/26872#26872).
You should have the PIT, and the MD5 file, and also the CSC file set up within Odin.
Then press and hold the VOLUME DOWN button, and then briefly press the POWER button, the device should go into download mode. From there Odin should detect the device, then start flashing as normal.
***Disclaimer:***
I am not responsible, please double check to make sure you have the right check-boxes ticked within Odin. If all else fails, refer to the XDA forum
***Another route:***
If you cannot get into Download mode, try the hard reset - that is, ensure the tablet is powered off completely, hold the VOLUME UP button, and then briefly press the POWER button, the device should hard reset itself.
And try the above again.

2012/08/18 | 596 | 2,397 | <issue_start>username_0: I can't go on to the Google Play Store! I do not know why. Last time I did, I tried to download 'HOM 2' which is a game, and cannot download it. It says "package invalid" and "phone storage is getting low". Then a while ago, I checked again, the Google Play Store and it says "Server Error retry".
I have already cleared the data and uninstalled updates..
Then switch off and on, the phone, but still Google Play Store still does not work!
Any advice would be appreciated.<issue_comment>username_1: Usually, when the APK states "*Package Invalid*", that means, ***either*** the package is corrupted or the application at the most, targets the version above the currently running Android on your handset, up to the latest and greatest version of Android, in other words, the minimum version of Android was probably raised above it.
*For example:*
An application that targets Android 4, Ice Cream Sandwich, if the minimum version is Gingerbread (Android 2.3.7), and the maximum version is Jellybean (Android 4.1), it is compatible from Gingerbread, Honeycomb, Ice Cream Sandwich and Jellybean.
If that was attempted to be installed on either Eclair (Android 2.1) or Froyo(Android 2.2) as in the case of the OP's question, you will get that message.
***TL:DR;*** the application is incompatible with the currently running version of Android.

The hosts file is at etc/hosts. If you are rooted, you can use root explorer. Go to the root directory and find the "etc" folder. Press the button on top to mount as read/write. Then find a file called "hosts" and delete it.
It should work instantly as it did for me. Hope that helps.

2012/08/18 | 553 | 2,184 | <issue_start>username_0: I have just received my 'new' HTC one V. The instructions clearly state to charge the phone up before first use, yet the the phone switched on and showed full charge straight away, before I had chance to charge it. My worry is that I have been sent a phone that someone else has had and I really want to be sure it is brand new to me.<issue_comment>username_1: It is not uncommon that rejected/refurbished phones find their way back to the market as "new" ones.
But in my (and at least Al Everett's) experience, batteries are almost always shipped with some charge. I wouldn't worry, as long as there are no other indicators that your device was pre-owned.
Upvotes: 4 <issue_comment>username_2: See [Wikipedia](http://en.wikipedia.org/wiki/Lithium-ion_battery#Disadvantages) on Lithium-Ion battery technology (especially sections "cell life" and "safety").
In short:
* Cell life is best at ~50% charged
* Safety requires the battery to be charged to above 3V (and below 4.2V)
* The best consumer experience would be to charge the battery to 100%
* The LiIon battery discharges itself during shipment/storage
* The battery's internal charging level detector may be incorrect and needs some cycles to self-adjust
As a trade off, it's charged to (my guess) 60% and then shipped. It's not full and may be even almost discharged when the customer gets it, thus tell them to charge it the first time. I guess the manual doesn't say it's **empty**, does it? It's the best tradeoff between cell life and the customer's first user experience with the device.
Upvotes: 3 <issue_comment>username_3: All batteries have some self-discharge so whatever their charge was initially they will discharge when sitting on the shelf. Also most batteries effectively "die" if they undergo very deep discharge. This is why all batteries are shipped charged - either fully or partially. So when you buy a battery (or a device) the battery will always be charged to some level which will depend on the manufacturing process and the time the battery spent on the shelf. This is why the battery level showing "full" chargealone is not a sign of the phone being not new.

2012/08/18 | 694 | 2,678 | <issue_start>username_0: I just upgraded Galaxy S2 (Epic 4G Touch) to Android 4.04. In the previous version, I could change the Default Silent Mode to Mute instead of Vibrate in the Sound settings. I believe this was under Vibrate settings; this could be changed to Never.
In this version, if I hold down the power button and choose Silent Mode it always goes to Vibrate mode instead of Mute. I can change the setting to Mute by going into the Sound settings, but it is much faster to hold down the power button (particularly when the phone is locked).
Any thoughts?<issue_comment>username_1: It's not possible using the power button long press for the Device Options menu in 4.0.4 on SG2. It always reverts back to "Vibrate" when changing Silent mode, albeit it is possible to press the volume down until it goes into vibrate, and then press volume down again. This takes a bit of time, though, and doesn't work unless you're past the screen lock. IMO, in a perfect world, this should only take one action.
**Conclusion**
Wait for a version update above 4.0.4 and hope they fix this BS. (Also, I friggin' hate people who think their phone is silent during meetings or seminars, and their phone just keeps buzzing and buzzing and buzzing. It's #\*@!ing Android trolling!)
**Hack**
The only hack I've found to make it work with the power button long press is going to Setting > Sound > Vibration intensity and setting ringtone vibration to zero. However, I'm pretty sure that turns off vibration globally, and you'll still see that annoying icon for "silence with vibration" when you use Silent mode trough the power button. :(
**Fastest way to mute**
Wipe off the screen lock. Flip down the curtain of the notificaions menu, then double tap the sound icon. That will bring you from sound to vibrate, and finally to mute. Or get a widget for muting.

Quick ways to go into silent mode (muting the phone):

* holding the power/lock button until a screen appears, then selecting silent mode (mute)

thanks,<issue_comment>username_1: It depends on the app in question. Handcent SMS / GoSMS have options for changing the LED colour. As an aside, there's also the ability to configure per-recipient tones, vibrate modes, notification icons and of course LED colours.
If you're looking for an all-in-one app to manage LED notifications for commonly used apps, give [Light Flow](https://play.google.com/store/apps/details?id=com.rageconsulting.android.lightflowlite) a try.

Upvotes: 2 <issue_comment>username_2: If you have a US Galaxy S3, all LED programs have issues with the colors (Handcent, GoSMS, etc) except LightFlow. If you select Green, it will be Blue, etc. LightFlow works flawlessly. The problme I have with LightFlow is the battery would drain faster with the app installed. I ran a test where I left the phone idle for 55 mins (no screen on, no led flashing, no gps, txt, phone..) and battery drainage was 8-10%. I uninstalled the app, and did the same test and battery drainage was only 4%. For now (until GoSMS supports LED for the US S3), I'm just using the built in S3 Led Notification option (under system settings). It works, you just can't change the colors.

Create a task once and it will execute automatically. Configure time and days of week when you want it to repeat. Morning, daytime, night, weekdays, weekends, you name it! Save battery by switching off unused functions when you don't need them.
***About Mobile Data***
Mobile data is available on all supported Android versions. I have tested it on Nexus One and Samsung Galaxy Nexus. However it may not work on some phone models, i.e. on HTC EVO 4G Mobile Data Off works, but On - doesn't.
I'm very sorry if this function doesn't work on your device, very often manufacturers block this and there's nothing i can do about it :(
Phone Schedule is a tool that allows you to create a list of tasks, which you want to automatically run at specific times. For example, you might want to switch your phone to silent mode when you go to bed, so you add a task, set time to 10pm, select desired days of week(say, Monday, Tuesday and Wednesday) and select action "Set silent mode". That's it! Your phone will automatically switch to silent mode at 10pm on every Monday, Tuesday and Wednesday.
Here's an example:
- Switch ringer off at night and switch it back on in the morning.
- Wake up to your favorite music by launching your internet radio app.
- Make your screen brighter during day time and keep it darker in the evening to save battery.
- Switch WiFi on when you get home and switch it off when you're off to work.
- Automatically turn off mobile data when you go to bed to save battery and turn it back on when you wake up
Phone Schedule is highly configurable, supports multiple tasks at one time, lets you specify days of week when you want specific tasks to run. If you want every task to trigger a notification in your phone's notification bar, you can easily enable notifications on the Settings page. Disabling notifications is just as easy ;) "Pause Tasks" function, use it when you have unexpected business meeting, so scheduled tasks won't execute during a timeout which you set.
Phone Schedule runs in background, so once you setup your tasks, you won't need to reschedule them manually, everything is done automatically.

My device is rooted with Ressurction Remix 2.6.1 with Siyah Kernel 3.2.7.2.<issue_comment>username_1: With [Tasker](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm) you are able to achieve this. The *Tasks* can be defined as e.g. *Wifi on* and there are different trigers for those Tasks. Amoung many others, *time* can be a trigger.

2012/08/19 | 388 | 1,435 | <issue_start>username_0: Someone suggested a pay-for app in another question and when I looked it up, it seemed it didn't have any trial version that has the feature for which I'd pay.
Now, I will not pay for something I have never seen working, even if it's only 4€ and so I was wondering whether I missed something or whether it's usual for pay-for apps to charge before you even can try it?
(This app, Moon+ Reader, does have a free version, but I'm specifically interested in a feature of the pay-for version, so the limited free version doesn't help.)
It seems like a very long time (maybe never) that I payed for any software on my desktop where there wasn't a demo of some sort to try out the key features you payed for.<issue_comment>username_1: You get 15 minutes trial of all paid apps listed in Play Store. Its Google's policy to refund money if you aren't satisfied but you'll have to claim refund within 15 minutes. After purchasing an app, just look for `Refund` button on app page in Play Store app.

2012/08/19 | 304 | 1,210 | <issue_start>username_0: I've got a new phone (Samsung galaxy SII) with Android 4 on it. I would like to be able to add Arabic support on it. Is there a simple way to do so ?
I'm a newbie with Android related subjects, so I'm not able to handle complicated processes.<issue_comment>username_1: ICS supports arabic, and you can add keyboard languages from the settings of the device
Upvotes: 2 <issue_comment>username_2: If you have android 4, Arabic is already supported. You need only to get to setting then language system wide and change it to Arabic or any other language. Unfortunately you can't have the option of Arabic with arabic-western numerals 123. They only have the stupid option: Arabic with hindy numerals.
Upvotes: 0 <issue_comment>username_3: Some of Samsung devices doesn't support Arabic even if it have ICS (Android 4), this usually happens if you ordered your device from outside (like from amazon), if you want to add Arabic, you'll have to flash a ROM that supports Arabic (like the official UAE ROM), if you bought the phone from an Arabic country, talk to the salesman.
For the keyboard just install any other keyboard from Google Play (e.g Go Keyboard, Swiftkey ...etc)

2012/08/20 | 713 | 2,787 | <issue_start>username_0: I have a rooted Nexus 7 Jelly Bean tablet and whenever I attempt to run an application from a terminal emulator app after chmod 777ing it and using the syntax ("./applicationName") it insists that I do not have permission to execute even though I granted my self superUser privs using ("su"). After that I did a little research and I learnt that if you copy the file to the (/data/local/temp/) directory you should be able to execute the application. So when I tried that it said that the file does not exist even though it shows up when listing the directory contents using ("ls")
I have no idea what steps to take, if it helps I am tried to run (scp) as a test but I wish to be able to run a custom compiled version of dns2tcp. I know I could have used better applications such as a hello world compiled natively onthe device but i couldnt get my hands on a C compiler for android such as gcc.
Thanks for any advice<issue_comment>username_1: Emulator app should be able to run another app from its own directory. That directory is called something like `/data/data/com.super.emulator`. Try giving the full path to the app you want in emulator.
If you want to get a compiler for Android, you can use [NDK](http://developer.android.com/tools/sdk/ndk/index.html). Easy to get, free to use.
Can't you also push your file to `/system/bin` via [adb](http://developer.android.com/tools/help/adb.html)? I don't know if you get that permission when you root your device. But if that's the case, it should make your life much easier.
Upvotes: 2 <issue_comment>username_2: try putting `sh` in front of your command, eg.:
```
sh ./scp
```
or
```
sh -c ./scp
```
Upvotes: 3 [selected_answer]<issue_comment>username_3: Most likely you can't run the program because of libraries on the device you ripped it from being missing from the device you copied it to.
Since your end goal is to compile a program and run it natively on the phone, might I suggest you use the [Android NDK](http://developer.android.com/tools/sdk/ndk/index.html)? The NDK documentation includes `STANDALONE-TOOLCHAIN.HTML` which explains how to cross-compile a native program to run on your Android device.
Upvotes: 1 <issue_comment>username_4: If you are rooted (I see you are), use the `su` command and then run your original script. If the problem is permissions, this should fix it. And if you are using a shell script, you can just add this line to it at the top. you might have to check your superSu settings (or whichever superuser app you have with root), and make sure your terminal emulator has root permissions.
If you are not rooted (or can't run as root for some reason), I suggest looking into how XBMC does it, as I believe it can run apps in user mode.
Good luck.

This might be one of the few legitimate uses for the Task Killer kinds of apps. Basically if you set the task killer to always terminate the "Camera" or "Gallery" apps, they should stop appearing in Android's recent apps list.\*

2012/08/20 | 1,060 | 3,716 | <issue_start>username_0: I have been following this guide to root my [Samsung Galaxy S](http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S%3a_Full_Update_Guide "Samsung Galaxy S: Full Update Guide @ CyanogenMod Wiki") smartphone. I've followed it to the letter, but after I load the new kernel to the phone, the phone gets stuck in a boot loop. The phone restarts after the kernel is loaded, it gets to the "Galaxy S" splashscreen, and then it goes off and restarts. Nothing else happens.
I have tried to get in to the recovery mode by holding the power, home and volume up button, and all this seems to do is hang the phone when it displays the same splashscreen. It does nothing else.
I'm really stuck, I've tried reloading the kernel several times since but nothing happens (I can get in to Download mode). I've also read on another forum that you can press the power button and the volume up and down buttons, but these don't do anything.
Many thanks for the help!<issue_comment>username_1: Edit
====
Honestly, I am not 100% sure that this was really a problem related to the kernel. I think that the "problem" could be also caused by the fact that pressing the home key in recovery mode results in a reboot. The correct way to select a recovery item is to press the power button.

9. A blue bar will come on the screen. After the flash is complete, the phone will reboot normally.
10. After the reboot, go to the Apps screen to check if the Superuser app is installed. If Superuser is installed, your phone is rooted.
To install Cyanogenmod, follow the following instructions:
1. Copy the rom to a folder in the sd card.
2. Copy the zImage file provided by Cyanogenmod into the Heimdall Suite directory.
3. Boot the phone into download mode.
4. Connect the phone to the computer.
5. Open Command Prompt.
6. Change the directory to Heimdall Suite and flash the kernel using the following command: `heimdall flash --kernel zImage`
7. The phone will reboot and go into a bootloop.
8. Turn off the phone by removing the battery.
9. Boot the phone into Recovery mode by holding `Volume Up` + `Home button` + `Power`.
10. Now flash the rom using the method mentioned [here](http://wiki.cyanogenmod.org/wiki/Samsung_Galaxy_S%3a_Full_Update_Guide)

However, since I won't to transfer file to and from PC/Mac, I prefer using PC/Mac to control which files I want to put/get. It is easier, quicker, and I don't have to fight with small device to properly check/uncheck files.
Basic settings like 'all files visible via BT' would be awesome.

Go to settings -> Apps -> Select "All" on apps tab -> Click menu and click sort by size.

It solved all my problem. Samsung told me to reset my device to factory firmware. I did not want to have to reinstall everything and now I know it will always happen after a while. Follow the procedure at that link and you might have to do it once or twice per year to keep it clean but you will not have to reset your device.

Recent versions of [Link2SD](http://www.link2sd.info/) can convert user apps to system apps and vice versa ([available on Google Play](https://play.google.com/store/apps/details?id=com.buak.Link2SD)).

The free version is limited to two profiles and "no security features".

In the context of software, the word "free" is ambiguous. Do you mean [*libre*, or *gratis*](https://en.wikipedia.org/wiki/Gratis_versus_libre), or both?
The following software packages ostensibly provide functionality that may make them adequate replacements for Titanium Backup Pro, depending on your use case. They are all *free software*. That is, they provide the [four freedoms](https://en.wikipedia.org/w/index.php?title=Free_software&oldid=730117990#Definition_and_the_Four_Freedoms).

Recent versions of [Link2SD](http://www.link2sd.info/) can convert user apps to system apps and vice versa ([available on Google Play](https://play.google.com/store/apps/details?id=com.buak.Link2SD)).
[SwitchMe](http://forum.xda-developers.com/showthread.php?p=21843503) offers a solution for switching among multiple user profiles ([available on Google Play](https://play.google.com/store/apps/details?id=fahrbot.apps.switchme)). The free version is limited to two profiles and "no security features".

In the context of software, the word "free" is ambiguous. Do you mean [*libre*, or *gratis*](https://en.wikipedia.org/wiki/Gratis_versus_libre), or both?
The following software packages ostensibly provide functionality that may make them adequate replacements for Titanium Backup Pro, depending on your use case. They are all *free software*. That is, they provide the [four freedoms](https://en.wikipedia.org/w/index.php?title=Free_software&oldid=730117990#Definition_and_the_Four_Freedoms).
* [Amaze](https://f-droid.org/repository/browse/?fdfilter=backup&fdid=com.amaze.filemanager) file manager;
* [oandbackup](https://f-droid.org/repository/browse/?fdid=dk.jens.backup);

2012/08/21 | 1,271 | 5,125 | <issue_start>username_0: To flash a Samsung Galaxy S (where do not have root access in the currently running OS, and with a stock recovery) with a new firmware (OS), I need to connect it with a USB cable to another computer and flash it from there.
There is a further problem if the other computer (which runs a GNU/Linux, Ubuntu) is ARM (it's a Toshiba AC100). So to flash a new OS onto the Samsung Galaxy S through the USB cable from the other computer, I'd need something like `heimdall` for ARM. It's not among the available [pre-built downloads for `heimdall`](https://github.com/Benjamin-Dobell/Heimdall/downloads). Perhaps, I will have to try to build it for ARM then...
Is obtaining heimdall for Linux on ARM possible?<issue_comment>username_1: ARM is currently not supported officially by heimdall.
You might have luck compiling it yourself:
<https://github.com/Benjamin-Dobell/Heimdall/>
My advice however:
Use a supported platform **once** (Win/Mac/Linux-x86/x64) and enjoy on-device updates from then on via ClockWorkMod recovery (CWM) or RomManager.
Reason: Heimdall is only needed to install a bootstrap CWM once. After that you use the regular CWM.
Here's the guide from cyanogenmod:
<http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide>
CyanogenMod releases for CM7/9/10 in various flavours (stable, release candidate, nightly build) can be found here (Galaxy S i9000):
<http://get.cm/?device=galaxysmtd>
Upvotes: 2 <issue_comment>username_2: Yep, you should be able to compile from source.
Here are the steps to install ClockworkMod with heimdall from GNU/Linux or Ubuntu or whatever (I tested it with Samsung Galaxy tab 2.0 7 P3110):
0. by following the steps below be prepared to lose your guarantee or brick your device. Also make backups of your personal data.
1. install Heimdall (and Heimdall-frontend) this software is a flash tool which copies firmware images to device's specific memory area. You can find several guides how to install this even from source. You don't need windows stuff such as odin or Kies or a fake software which contains the usb drivers because most probably the kerner drivers are preinstalled on your GNU / Linux OS.
dmesg
2. download the recovery image to your host computer from clockworkmod rommanager (I'm not allowed to post URL. This is www dot clockworkmod dot com slash rommanager). Find your device on the list and download some files from 3 columns. Currently there are 3 columns:
~ROMs / ClockworkMod : contains superuser.zip: copy to sim card or to device. This zip contains application which allows to execute android apps with root mode. It is not needed to backup/restore device partitions. superuser.zip can be installed in recovery mode. Default recovery of Samsung (stored in RECOVERY partition) does not install the zip due to error: signature verification failed. If you want to root your device you must install a custom recovery image. Backup of original firmware does not require this superuser hack.
~Download Recovery: this is a custom recovery partition: you can install zips or create backup or flash partitions. You can navigate between the menus with keys only - no touch : volume up and down and choose with power button. Copy this to your GNU/Linux host (this image will be written to device with Heimdall)
~Download Touch Recovery: this is a custom recovery image. You can navigate between the menus with keys or touch : volume up and down and choose with power button. Don't forget to scroll there are a lot of menuitems!
1. turn off the tablet (wait around 10 secs while screen goes black)
2. hold down the volume key which is next to the power button and hold down the power button. You may keep it pressed as long as you like: logo appears then device reboots. When logo appears release keys. Android system recovery <3e> loads. Choose wipe data/factory reset with volume then select with power button. Choose Yes -- delete all user data.
3. choose reboot system now and don't allow it to reboot: immediatelly hold down the power button and the volume key which is on the far side. Keep it pressed until warning appears. Connect tablet to GNU/Linux host with USB cable then press the volume button next to power button.
4. with root permission run command on GNU/Linux host and be prepared for executing next step immediately
sudo heimdall flash --RECOVERY recovery-clockwork-touch-6.0.2.7-p3110.img
5. when it completes it restarts the device: remove the cable and immediatelly boot into recovery mode: hold down the volume key which is next to the power button and hold down the power button: keep it pressed until logo is displayed on 2nd time then release them.
6. ClockworkMod Recovery loads... scroll down to see all the menuitems. You can create backup with "backup and restore" menu then "backup to external sdcard"
7. After all use last menuitem: +++Go Back+++ / reboot system now. "ROM may flash stock recovery on boot. Fix? : If you choose No then you can do the procedure again... / If you choose Yes then Samsung's recovery firmware gets overwritten by ClockworkMod Recovery.

2012/08/21 | 733 | 2,975 | <issue_start>username_0: In most cases where the keyboard is needed, it pops up automatically. However, I am trying to play Dungeon Crawl Stone Soup Webtiles on my tablet, and it does not bring up the keyboard. Is there any way to bring it up manually? I'm on a Nexus 7, running Jelly Bean. Ideally, there would be something that did not show up on the status bar, but sat in the notification drawer, and I could tap that to bring up the keyboard.
Actually, even better would be something that sat down in the bottom, next to the navigation controls, but I don't believe that's possible without modifying the framework.<issue_comment>username_1: As I see an alternative keyboard may solve your issue, and this seems to be an acceptable solution, *and* you even mention something you cannot find -- hereby I proudly present:
[Hacker's Keyboard](https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard)
Checking its [Guide](http://code.google.com/p/hackerskeyboard/), there's in fact a section suggesting such a feature:
>
> You can configure the gesture used for this in the keyboard's "Gesture and key actions" settings menu. If the swipe action is too hard to trigger, try binding the "close keyboard" action to the "Volume down" hardware key. This won't interfere with normal use of the volume button while the keyboard is closed.
>
>
>
Though this applies to "close": If there are gestures you can configure, it might as well be able to have one for "open". The [FAQ](http://code.google.com/p/hackerskeyboard/wiki/FrequentlyAskedQuestions) may reveal some more clues.
SaintWacko notes in the comments:
>
> To be able to open it anywhere, you go into the settings for the keyboard and check the box for 'permanent notification'. It will then keep an entry in the notifications which you can tap to bring up the keyboard at any point.
>
>
>
So this would be an alternative possibility -- the hook being it is hooked to this special keyboard.

Download the hackers keyboard, then go into settings and enable ''use permanent notification''. This puts the hackers keyboard logo at the top right of your screen next to the clock and settings button. Click on the settings bar or clock at the bottom right and press ''Show Hackers Keyboard''. It will popup for you in flash and other times when it doesn't do it automatically.

Upvotes: 2 <issue_comment>username_4: I used a combination of "Hacker Keyboard" and "Smart Status Bar". Both free, no root required.
I set "permanent notification" in the Hacker Keyboard settings. Now, all I have to do in my full screen game is swipe from the top of the screen to bring down the notification menu, and then I select Hacker Keyboard.
Simple as that now.

2012/08/22 | 3,709 | 12,705 | <issue_start>username_0: I want to learn a language or prepare for an exam with the help of my Android phone or tablet.
Are there any efficient and fun methods out there to do so?<issue_comment>username_1: [Flashcards](http://en.wikipedia.org/wiki/Flashcard) are a great way to study. I can recommend [Anki](http://ankisrs.net/) and [Ankidroid](https://play.google.com/store/apps/details?id=com.ichi2.anki) ([Google Code Project Page](http://code.google.com/p/ankidroid/wiki/Index)) for Android. It's fun to use and really efficient. There are even existing card decks from various topics that you can use to learn, extend with information and then share again to the community.
Upvotes: 3 <issue_comment>username_2: For learning a new language, [Pimsleur](http://en.wikipedia.org/wiki/Pimsleur_method) and [Rosetta Stone](http://en.wikipedia.org/wiki/Rosetta_Stone_%28software%29) approaches are considered to be widely accepted (can't avoid Weasel words).
I've used both in computer and I am glad to know that Rosetta Stone has an android app named [TOTALe](https://play.google.com/store/apps/details?id=com.rosettastone.mcp&hl=en) for this purpose.
While Pimsleur's approach involves listening to audio and referring PDFs, this approach can work out on any device.
Where as Rosetta Stone's approach is little bit interactive and can be done only through an application.
Upvotes: 2 <issue_comment>username_3: I could list up a bunch of stuff here now, but that would get quite long. So let's better organize it by groups:
Covering multiple topics
========================
First, of course, there are mentioned **Flashcard** apps (best-rated here are probably [Learn Easy](https://play.google.com/store/apps/details?id=eu.junghans.learneasy) and [AnyMemo](https://play.google.com/store/apps/details?id=org.liberty.android.fantastischmemo) -- a longer List can be found at my AndroidPIT overview [Vokabeln & FlashCards](http://www.androidpit.de/de/android/forum/thread/428510/) (Google Translate version [here](http://translate.google.com/translate?sl=auto&tl=en&u=http%3A%2F%2Fwww.androidpit.de%2Fde%2Fandroid%2Fforum%2Fthread%2F428510%2FUebersicht-Vokabeltrainer-Flashcards)).
These are not only restricted to languages, as mentioned AnyMemo shows[1](https://i.stack.imgur.com/DWrvd.png): being able to also use images, you can use it for everything -- think e.g. of images of molecules, electronic wiring examples, and others.
 
Languages
=========
Second, there are the "big **language guides**" -- again I can refer to an overview at AndroidPIT: [Sprachführer](http://www.androidpit.de/de/android/forum/thread/431685/) (and the Google Translate variant [here](http://translate.google.com/translate?sl=auto&tl=en&u=http%3A%2F%2Fwww.androidpit.de%2Fde%2Fandroid%2Fforum%2Fthread%2F431685%2FUebersicht-Sprachfuehrer)). Though this latter mainly addresses German native speakers, the end of the list has some generic hints.
 
While FlashCards & Co focus on learning words, the more complex language guides also cover grammar and complete phrases. I guess best is to use a combination. As for the FlashCards, any solution should do: they are mostly not language specific. Other with the language guides, where it lies in the nature of this type that it has to be specific at least to the target language you want to learn. Examples here include [French Class Demo](https://play.google.com/store/apps/details?id=com.ceardannan.languages.french.demo)[3](https://i.stack.imgur.com/JhfIa.jpg) and [Italian in a Month Free](https://play.google.com/store/apps/details?id=com.elky.likekids.itfree)[4](https://i.stack.imgur.com/WXipU.jpg).
A third category should not be forgotten to mention here: Get yourself a good **eBook Reader**, and add some books to it which are written in the language you want to learn. I recommend [Moon+ Reader](https://play.google.com/store/apps/details?id=com.flyersoft.moonreader)[5](https://i.stack.imgur.com/xBcn8.jpg) here, which already includes a huge Online Library list for multiple languages (which actually is sorted by languages even), so the reader immediately has some ressources at hand. Having trouble with some words while reading? Simply long-tap the word to open a dictionary -- either online translation, or an offline dictionary like [Fora](https://play.google.com/store/apps/details?id=com.ngc.fora) or [ColorDict](https://play.google.com/store/apps/details?id=com.socialnmobile.colordict)[6](https://i.stack.imgur.com/hvl0f.jpg), which both can deal with [StarDict](http://en.wikipedia.org/wiki/Stardict) files saved on the sd card. Being able to mark and even annotate with *Moon+ Reader* (see the picture[5](https://i.stack.imgur.com/xBcn8.jpg)), one could also use this app for other subjects/classes.
 
Number four now should be obvious: There's that Youtube app one could check some **language specific movie[clip]s** with. Or get some other movie player ([MoboPlayer](https://play.google.com/store/apps/details?id=com.clov4r.android.nil) probably being a good choice), plus some videos in the targeted language.
Guess number 5? Right: **Music**. There are plenty of music players around, and songs to pick. Repeating them over and over is baking some phrases to ones brains :) Beside this fact, there are also some audio books and language-learning audio files around.
Science
=======
So far on language-learning -- but your question was not restricted to that, as I just notice. So let's go for some more possibilities -- pointed out in the AP overview [Formelsammlungen & Referenzen](http://www.androidpit.de/de/android/forum/thread/428406/) (Google Translate: **[formulas & references](http://translate.google.com/translate?sl=auto&tl=en&u=http%3A%2F%2Fwww.androidpit.de%2Fde%2Fandroid%2Fforum%2Fthread%2F428406%2FUebersicht-Formeln-Nachschlagewerke-fuer-Schule-Studium-Chemie-Mathe-Physik)**). There are tons of references for chemistry, like e.g. the very famous [Merck PTE HD](https://play.google.com/store/apps/details?id=de.merck.pte) (periodic table)[7](https://i.stack.imgur.com/QJD5U.jpg), mathematics calculation helpers and references like e.g. [Mathematics](https://play.google.com/store/apps/details?id=de.daboapps.mathematics)[8](https://i.stack.imgur.com/Rgtf9.jpg), physics references, electronics, stuff for engineers... So learning is clearly not restricted to languages.
 
School Organizers
=================
Learning for school or study? Multiple subjects to cover, and courses to keep track of? This also can be covered using your Android smartphone or tablet. The AP overview dealing with this would be [Stundenpläne und Schul-Organizer](http://www.androidpit.de/de/android/forum/thread/442568/) (Google Translate: **[school organizers](http://translate.google.com/translate?sl=auto&tl=en&u=http%3A%2F%2Fwww.androidpit.de%2Fde%2Fandroid%2Fforum%2Fthread%2F442568%2FStundenplaene-und-Schul-Organizer)**). From simple timetables like [School Schedule](https://play.google.com/store/apps/details?id=com.schoolschedule)[9](https://i.stack.imgur.com/aj2a6.jpg) to just keep track of what subject is running when and where, to apps also keeping track of related tasks and even silence the device during classes (e.g. [My Class Schedule](https://play.google.com/store/apps/details?id=de.rakuun.MyClassSchedule.free) -- note the tiny numbered boxes on the blue items in the screenshot[10](https://i.stack.imgur.com/gWu0r.jpg), which indicate connected tasks), you can find many solutions.
 
Summary
=======
To sum up: There's a lot of stuff you can pre-load to your tablet -- and then use to learn on-the-go.
Upvotes: 6 [selected_answer]<issue_comment>username_4: Check with your local Public Library (talk to your librarian). Many offer research apps, or free access to language tools. My library gives me free access to Mango Languages for example. Unless they are very small they will likely have a ton of other resources educational and informative as well.
If you are in the US, you might look up semi-local libraries in the same state. Most libraries in the US will give cards to anyone in the same state. If the library has useful apps available for free, they'll likely also have a good web presence that will tell you what you need to do to access the apps (probably just have a library card) and what you need to do to get a library card.
Upvotes: 3 <issue_comment>username_5: Learning a language could be really fun if you could snap a photo of a word in your native language (I've only tested to translate from English -worked- and from Arabic -didn't work-) and find a translation quickly to another; for that I found [**Google Goggles**](https://play.google.com/store/apps/details?id=com.google.android.apps.unveil) ; a convenient solution that also doubles as a QR-code reader (requires Internet access). Google Goggles only makes out the words in the image taken, and thus you would need to also install a translator [**Google Translate**](https://play.google.com/store/apps/details?id=com.google.android.apps.translate&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5nb29nbGUuYW5kcm9pZC5hcHBzLnRyYW5zbGF0ZSJd) to direct your image's text to for translation (I presume it isn't narrowed down to only Google Translate, of that however I am unsure).
Also organizing to-do lists could be nicely done on tablets/phones. **Wunderlist** is my current choice to managing to-do lists, since it has both a chrome add-on (found [here](https://chrome.google.com/webstore/detail/fjliknjliaohjgjajlgolhijphojjdkc)) and a mobile app (here's the link to that on [Android](https://play.google.com/store/apps/details?id=com.wunderkinder.wunderlistandroid&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS53dW5kZXJraW5kZXIud3VuZGVybGlzdGFuZHJvaWQiXQ..)). It helps you categorize your to-do's through separate lists, prioritize to-dos (only 2 priorities: either important by clicking on a star, or normal priority), and easily view/add tasks for nearing times, such as "Today", "Tomorrow" and "Next 7 days". You need internet connection for syncing.
Of the most obvious features for a tablet (or phone) is to have any needed reading material on the go, and easily accessible. If however you're reading from your computer, it could be more convenient to have a remote to help you navigate through your documents/presentation slides; reading easily without having to reach out for the keyboard. Although this might seem as lethargic behavior, it could be used to the contrary of purposes; for example using a treadmill while flicking through presentation slides or perhaps rehearsing a presentation (where there would be someone assisting with the slide navigation) without the need to reach out to the keyboard/mouse. Such apps would need wireless connection (WiFi and/or bluetooth; I think it varies- I haven't tried out remote apps much). The remote app I've recently came across is [**Unified remote**](https://play.google.com/store/apps/details?id=com.Relmtech.Remote&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5SZWxtdGVjaC5SZW1vdGUiXQ..) for which you should need to download a server on your computer (it also has a portable version). I haven't quite tried out this remote (or others), so cannot give a review.
Hope this helps. Happy learning!

2012/08/22 | 909 | 3,609 | <issue_start>username_0: I'm trying to restore a new device with apps from my old device, but neither Android Market nor AppBrain seems to automatically bulk install them? When I use the Execute method in AppBrain it seems to only send me to manual install of all apps, which probably would take a long time since I use a number of apps.
Is there some way to make AppBrain bulk install a list in a batch or is it possible to move the apps from my old device to the new one?<issue_comment>username_1: You can install Titanium Backup in your old device and backup all "user installed" apps + data to SD card. In your device, put this SD card and install Titanium Backup again and restore "user installed" apps + data.
Though I have not tried this across devices, I had tried this with same device using different ROM. I had backed up from a stable ROM and whenever I install a new ROM I would use the above method to install all my apps with its data.
I had already asked [this](https://android.stackexchange.com/questions/27695/switch-roms-still-seamlessly-use-apps-and-its-data) question and it has been answered referring Titanium Backup.
Upvotes: -1 <issue_comment>username_2: I don't know of a way to do this. I recently bought a new phone, and to save myself the tedium of manually installing 40 odd apps, I went to the Google Play Store using a desktop browser. It will already have a list of apps you have installed under My Apps, so you can quickly spin through the list and install them - you don't need to wait for each app to install.
Upvotes: 4 <issue_comment>username_3: Assuming you've previously installed AppBrain and synced your device, you can do the following:
1. From Google Play Market download and install [AppBrain](https://play.google.com/store/apps/details?id=com.appspot.swisscodemonkeys.apps) and [Fast Web Installer](https://play.google.com/store/apps/details?id=com.appspot.swisscodemonkeys.apppusher) apps.
2. Open the Fast Web Installer and sign in with your Google account (same one you are using on Play Store).
3. Open the AppBrain app, and sign in with your AppBrain account.
4. Go to Preferences, and then use the "Enable Fast Web Install" option.
5. Under Menu go to "More lists..." option, select the previously synced list, tap the "Add all apps" button, and tap the back button.
6. Tap the "Execute" button, and after reviewing the permissions tap the "Install" button. This should download and install apps in batch, without having to confirm each one separately.
You can also create lists of apps via AppBrain's site, and these lists should show up in the app.

How to mass-install apps with the Play Store:
1. Open the Play Store
2. Go to My Apps
3. Go to All
4. Keep your finger pressed on an app that has not been installed yet for a second or so.
5. Now the play store goes into selection mode, you can simply select all the apps you want and press the "Install" button at the top when you
re done.

On each device:
1. Open Google Play Store
2. Tap your profile icon
3. Tap Manage apps & device
4. Under "Share apps" select Send or receive
5. Approve the location permission dialog
6. Select apps and confirm the pairing code.
On both the sending and receiving side there's a button to select-all.

2012/08/22 | 682 | 2,581 | <issue_start>username_0: My HTC One V (on 4.0 ICS) seems to be continuously downloading something even when it's inactive, and it's using the battery abnormally fast.
My data usage graph:
[](https://i.stack.imgur.com/MTbSZ.png)
(click to enlarge)
On the first picture, the brown line is for the "Android OS" element, which as you can see is responsible for at least 60% of the data consumption. I don't know what Android is downloading, but it does it continuously and it has a big effect on my battery's life. When I disable mobile data, the battery usage line becomes flat (see second picture). How can I check what exactly "Android OS" is doing? And how can I disable this activity?
Here is the battery usage graph. As you can see, the line became flat when I've disabled mobile data.

2012/08/22 | 454 | 1,717 | <issue_start>username_0: In the Google Play Store, when an app is too large in size, a "WiFi" tag is mentioned next to the app name. That way the user can know that the download is heavy.
At what application size does Android add the WiFi tag to apps ?<issue_comment>username_1: While there is some conflicting information, the limit at which the market adds the WiFi tag appears to be 25MB.
Upvotes: 2 <issue_comment>username_2: Good question. I believe the answer has been recently changing, because while I was initially under the same impression as username_1 (thinking the cutoff was 25 MB) I have been unable to find any Google documentation defining such a limit.
What I have found is that the [maximum APK (app) size](https://support.google.com/googleplay/android-developer/bin/answer.py?hl=en&answer=113469) is [50 MB](http://developer.android.com/distribute/googleplay/publish/preparing.html#size). Developers can also choose to use up to two [APK expansion files](https://support.google.com/googleplay/android-developer/bin/answer.py?hl=en&answer=2481797&topic=2365760&ctx=topic) to be downloaded along with with the app's APK, each of which [can be up to 2 GB](http://developer.android.com/guide/google/play/expansion-files.html). Even for these larger expansion files, though, I could find no mention of Wi-Fi only download restrictions (unless [explicitly required by the developer](http://developer.android.com/guide/google/play/expansion-files.html#Progress)). I remember seeing the Wi-Fi download flag you mention on some larger apps that I use personally, but today I've gone back to those same apps and don't see that flag.
As best I can tell this policy has changed.

2012/08/22 | 2,023 | 8,068 | <issue_start>username_0: As an owner of a Nexus One running Gingerbread, I'm continually fighting to keep free space in my phone's Internal Storage. Today, I noticed something odd.
The bottom of Andorid's "Manage applications" screen shows a bar graph that reports the phone's "Internal storage" (I have 29M free). When I click into an app, I can see storage for the "Application", and for the app's "Data". The application, in most cases, is stored on the SD Card. The application's "data" is stored on the phone (I presume).
What I'm finding is that I'm not seeing the whole picture of what is taking up Internal Storage. For example, I have 29M free in Internal Storage. The Angry Birds app, which is stored on the SD card, is 3.14M. It's Data is 4.0K. I then delete the Angry Birds (gasp!), and my free Internal Storage jumps up to 31M. So it looks like it's freed up 2M, when I only would have expected it to free up 4.0K. Any idea what's going on here?<issue_comment>username_1: This sounds like you are using Apps2SD or equivalent whereby, moving the app onto the SDCard, only a portion of the app is stored in the internal storage and the rest on the SDCard.
For verification, check your SDCard and see if the app's data is still there, this should be present in `/sdcard/Android/data/` followed by the package name of the installed application.
That is a normal mechanism of the Apps2SD.

1. **The Free space reported**
The free space reported at the end of the "Manage Applications" screen is rounded to MB, and it gives you a general free space estimation based on the moment you opened said screen, and it gets updated from time to time (by my tests about every minute).
I've mentioned "rounded" because if you access the "Storage Settings" panel, you'll get a clear picture regarding the free space available, down to KB.
2. **The App Allocation**
As already mentioned by username_1, an application may be entirely moved to the SDCard or leave a portion behind, this issue is more related with the development of the application itself and there's no standard rules to follow.
I've performed an exercise with "Angry Birds", and while the download mentioned 20MB, after installed it consumed 24MB. After moving it to the SDCard using the option for this end under "Manage Applications" screen, 1.85MB were left behind on the Internal Storage, plus 4KB of data.
3. **Temporary System Files from other applications or running services**
While I was writing this answer, the free space reported varied between 2MB, this tells us that the OS is constantly creating and freeing up space depending on the stuff running.
There may exist other factors that concern the ext4 File System specifications used by Gingerbread , but I don't believe they better account for the 2MB difference.
---
By the three points mentioned above, while performing an exercise with the application you've mentioned using a device with a stock Gingerbread ROM, I've managed to account for 2MB of difference, just like the space you've mentioned.
Determine Internal and External Space Occupied
==============================================
Following up on the comments, regarding a way to accurately know how much an app occupies on the device, and being able to view it by external or internal storage, the most accurate application I'm currently using is [SanDisk Memory Zone](https://play.google.com/store/apps/details?id=com.sandisk.mz) by SanDisk Corp. available for free from Google Play Store.
1. Open the application
2. Select the desired storage
3. Check the details about it
Upvotes: 3 [selected_answer]<issue_comment>username_3: Checking around, I just found a few useful apps which reveal where the storage goes.
For one, there's [DiskUsage](https://play.google.com/store/apps/details?id=com.google.android.diskusage). Though the screenshot[1](https://i.stack.imgur.com/xCMca.jpg) shows the sdcard here, the video on the apps playstore page makes clear it can be used on internal storage as well -- and even links to the apps page you usually find via *Menu -> Applications -> Manage Applications*. You can walk and zoom in/out each area, as the annotations on the screenshot show.
My second candidate is [Folder Size Chart](https://play.google.com/store/apps/details?id=com.ponpocostep.foldersizechart), which comes with a different design and, as seen in the screenshot[2](https://i.stack.imgur.com/l8hL6.jpg), can also deal with internal storage.
 
These two may definitly help to identify "storage hogs". There are many others found in the playstore which follow this concept, but most are limited to the sdcard or require root access.

I [asked a related question](https://android.stackexchange.com/questions/20202/multiple-force-closes) when I started experiencing apps force-closing due to a lack of partition space and later consolidated my understanding of the data partitions in an answer to a question about [False “low on space” (internal storage) warning on HTC Incredible](https://android.stackexchange.com/q/21300/11343):
>
> ...my app settings screen shows me what must be the `/data` usage (never close to full, numbers match `/data` size reported by DiskUsage) even though my apps are actually constrained by the much smaller `/data/data` (where I run out of room often)...
>

I found that the number reported as "Internal Storage" was reporting something entirely unhelpful and was, by all accounts, useless in helping me actually manage app storage. I concur with username_3 in his recommendation of [DiskUsage](https://play.google.com/store/apps/details?id=com.google.android.diskusage&hl=en), I found it very helpful especially when rooted (with root permissions it can display `/data/data` partition usage). [Using terminal emulator](https://android.stackexchange.com/a/20297/11343) to investigate usage was also helpful in diagnosing my problem. When you take a look at your `/data` and `/data/data` partitions, do you see the same discrepancies?
Upvotes: 2 <issue_comment>username_5: Many people have that kind of problem and I have the same one. Moving apps to SD card just delays a bit the problem because something else fills up the internal storage. I finally figured out and it works great.
I have a Galaxy Tab 7 but many android devices will experience that. The one called `/data` is actually not really just data but it is where Android install the application apk and some of the data related to it. If you force the apk to install on SD card, it will still use some of the `/data` space (small amount) for some data.
The problem I discovered is in `/data/tombstone`, you will find 10 files named `tombstone_0#`. These are constant/non-stop debugging info collected by android. These files build up over time. You don't need that for a normal user. Delete all of them. These 4 files were using 1.4GB of my 1.89GB internal tablet storage.
To do so, you will need to root your device. Yes, you must. And it won't explode don't worry, I've done it and many others too! Then get a program like "Root Explorer" to browse and delete the junk. It will request and be granted root privilege if you rooted your device before and you will be able to do whatever you want.
To root your device, just google "root android [my device model]" and you should find quickly how to root your device.
This problem is a design flaw. When there is a low internal storage, Android should start a background task to clean up that junk.

Will I lose root?<issue_comment>username_1: Generically speaking, if you've only rooted the device and haven't actually installed another ROM, you should be able to apply the OTA update, but you will lose root because of it. You can always root again.
This is mentioned on several forum threads:
* XDA-Developers Thread: [Root and OTA updates](http://forum.xda-developers.com/showthread.php?t=1334777)
* androidforums Thread: [Rooted GNex - What will I lose if I OTA update](http://androidforums.com/international-gsm-galaxy-nexus-all-things-root/492142-rooted-gnex-what-will-i-lose-if-i-ota-update.html)
As one can see by the posts on each one of the above threads, there's a device agnostic consensus. Users report that OTA updates are possible on rooted devices, but root is always lost.
The reason behind this is that updates essentially replace or add system files, and the permissions on these files that the rooting process has changed to give you root access, are changed to the ones that come with the update, that don't allow root access.
Upvotes: 1 <issue_comment>username_2: You can also try using an app such as [Voodoo OTA Rootkeeper](https://play.google.com/store/apps/details?id=org.projectvoodoo.otarootkeeper) to protect your root. On supported phones, it can preserve root through an OTA update. It must be installed and set up *before* you apply the OTA update.

2012/08/22 | 641 | 2,413 | <issue_start>username_0: I would like to take an installed app, including its data, from a rooted Android device and produce from it an APK suitable for installing on a non-rooted Android device.
Is this possible?
*Edit: Existing answers/comments seem to reinforce the idea that existing apps do not support embedding an app's data within an APK. Perhaps the more fundamental question is,**can** an APK embed files destined for* `/data/data/[appname]`*, or are they restricted to being self-contained when installed?*
Notes:
* I assumed that, if it were possible, this functionality would be built into an app such as Titanium Backup. Titanium Backup can back up app+data to a single file, but that file is not an APK and can only be restored by Titanium Backup itself - which is no help for me as the destination device is not rooted and so cannot run TB.
* Solutions that require use of the terminal on the phone or ADB are fine.
Thanks.<issue_comment>username_1: You can still get the APK of an app with applications like [ES File Explorer](https://play.google.com/store/apps/details?id=com.estrongs.android.pop&hl=fr), [AppMonster](https://play.google.com/store/apps/details?id=de.android_telefonie.appmanager&hl=fr) or [Titanium Backup](https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&feature=related_apps#?t=W251bGwsMSwxLDEwOSwiY29tLmtlcmFtaWRhcy5UaXRhbml1bUJhY2t1cCJd). But I don't know if they back up datas when the APK is built.
Upvotes: 1 <issue_comment>username_2: Having now read more about the APK file format, I think I can now safely answer my own question with "it's impossible".
An APK file does not contain a data structure which is "unpacked" on install like the packages used by, for example, most Linux distributions. Instead, an APK is simply a self-contained, rebadged JAR file that contains the application's bytecode, manifest and certificate and nothing else.
The contents of `/data/data/[appname]` are presumably created by the application code when it is first run (or at some future point), and there is no way of embedding such data into an APK so that the system automatically moves it to the correct destination at install time.

2012/08/23 | 370 | 1,450 | <issue_start>username_0: A friend of mine and I have the Samsung Galaxy Tab 10.1.
His tab is flashed with a custom kernel giving 1.2Ghz instead of the 1Ghz I have by default.
Using antutu benchmark, we saw what we expected, his device had a better score about 700 points.
My question is if his tab in comparison with mine will consume battery quicker.
On the other hand, having installed the CPU SPY and we saw that 1.2ghz and 1ghz are both used.
The second question is does the device make use of the speed needed (from 216 to 1200) depending on the effort?
If the device smartly uses the right cpu speed neede, does the 1.2ghz means a new better alternative for heavy tasks right?<issue_comment>username_1: Yes you're correct. Android will use CPU frequency as required including deep sleep to highest CPU frequency. If Android uses 1.2Ghz for high end task it will consume more battery but on the other hand will finish the task quicker than 1Ghz.
Many custom ROM also allows you to change this CPU scaling behavior by changing the governor. For eg: if you choose governor for high performance then Android will try to scale CPU to higher frequency.
Upvotes: 3 <issue_comment>username_2: A faster CPU does not always mean more power consumption. Tegra 3 for example has a special "battery safe" - core that is used in idle mode or when not much power is needed and will need less battery even though the main cores have more GHz.

We all know as to how to connect our android phone with our laptop so as to use our laptop's internet connection in our android phone.
But my question is how to be directly connected to internet on the laptop and connect my Samsung Galaxy Y mobile to it, so as to use the laptop's internet connection in the mobile.

Reason: Why I need to do that.
I Live in the country of India. MTS was the first country to launch 3G Plug-and-Play Modems in India. I have one of those. The device has a direct connection and does not requires insertion of a SIM card. I can connect it to my Laptop and use the internet service, but it is not possible to connect it to the mobile phone.
P.S: Fell free to migrate it to SuperUser if you guys think it belongs there.<issue_comment>username_1: Turn your laptop into a WiFi hotspot. See [Turn Your Windows 7 Laptop into a WiFi Hotspot with Connectify](http://www.howtogeek.com/howto/9739/turn-your-windows-7-laptop-into-a-wifi-hotspot-with-connectify/) as an example. In a GNU/Linux system, use `hostapd` for this purpose. (Actually, if you don't like the idea of writing a configuration file for `hostapd`, the popular NetworkManager tool also supports managing an AP now, but this is not available through its GUI tools; it requires a manual tweak in its configuration file for `mode=ap`. ">Reference in Russian.)
Then use WiFi from your mobile phone to connect to the laptop's WiFi.

2012/08/23 | 711 | 2,914 | <issue_start>username_0: Well, finally got my Nexus 7. Set up all the basics and hit a pretty big roadblock, the email account setup for IMAP simply won't work.
Just to clarify, I'm absolutely certain all the details I've put in are 100% correct, I've double-, triple-, quadruple- and so on-checked them. They are exactly the same as the settings I use on my iPhone, in Mail.app on my Mac and in Thunderbird on my laptop. All three of these devices are on the same network behind the same FreeBSD machine that does packet filtering, they are all on the same subnet and subject to the same packet filtering rules.
The IMAP(S) server is my own running on a Debian VPS and here's the kicker, when I check the logs all the other clients' connections are clearly visible but no connections from the Nexus 7 show up. The Nexus 7 has shown no other signs of network issues but whenever I try to setup an IMAP account I get `Couldn't open connection to server`thrown back at me immediately (no delay indicating some kind of timeout, immediate, right away, BAM!).
So, does anyone have suggestions on how I can fix this? I've tried googling but every forum post and blog post I've come across has been so obviously about other things (most of them along the lines of "I'm trying to my email what is server?" which means the answers aren't very helpful).
Edit: I've also tried a complete factory reset but I'm still getting the same error.
Edit2: I am able to telnet from the tablet to the IMAP server and when I do so everything that should get logged in `/var/log/mail.log` on the server gets logged there but when I attempt to setup an account in the settings and click Next I still don't see anything in the logs. I'm starting to have suspicions that this is either something strangely broken in the the IMAP client libraries or some kind of IPv6-related screwup (since the server is accessible through both IPv4 and IPv6).<issue_comment>username_1: Ok, I tried restarting the IMAP server with no luck and then I decided to try a second factory reset, not that I was expecting it to work but apparently something changed because suddenly it worked and I have no idea why. Ah, the magic of user-friendliness.

I realize there are several options for this, and I have tried many of them, but none seem to fulfill two crucial requirements:
1. It has to really act like a printer, which means it has to immediately display the pages when I hit PRINT with no other intervention from me, including no app launching.
2. It has to expose itself as a normal IP printer on the local network (connected via WiFi) and accept normal network print jobs. Not going over the "cloud" like so many printer apps.

But I do not know if the PC does recognize it or not as the tablet does not show up on the removable storage. I have tried several different things to get it to do so but none of them work.
One of the attempted things is to enable USB mass storage on the tablet. But when I try to do that it does not have a place for it in the Settings. Can anyone help me with this?<issue_comment>username_1: On Android 4.0+ devices, certain devices without a separate memory partition (i.e. separate sd card) don't have the **USB Mass Storage** option, rather Android now uses [**MTP (Media Transfer Protocol)**](http://en.wikipedia.org/wiki/Media_Transfer_Protocol) or [**PTP (Picture Transfer Protocol)**](http://en.wikipedia.org/wiki/Picture_Transfer_Protocol) to transfer files.
NOTE: If your device supports SD Cards, please make sure that an SD card is available in the device before connecting it to the PC.
To configure between MTP and PTP (and USB Mass Storage if an SD card is available): go to **Settings > Device > Storage > Menu > USB computer connection.**
To **transfer files to your device via MTP**, make sure it is in the MTP mode, then connect it to your computer via a USB cable.
On Windows: wait for Windows to install the necessary drivers, then your device will be available in My Computer. ([more info](https://support.google.com/android/bin/answer.py?hl=en&answer=1650161&topic=1650156&ctx=topic))
On Mac: You have to install the Android File Transfer software. Follow the steps on this [support page](https://support.google.com/android/bin/answer.py?hl=en&answer=1649773).

Can you open it?
You may need to try a couple of times,
When you do get it to open, run scandisk (right-click the drive, select properties, open Tools tab, select scandisk).
After scan and repair, defrag the SD Card.
This should fix any file errors, you should be good to go.
If the SD card wont open, maybe you need to try downloading the free Minitool Partition Wizard software. This should access the card and allow you to rescue data. (The Rescue My Files program is also good)
*Sigh* If all this fails, format the card and get a new life but this time subscribe to a free cloud backup system.

==========
Android has specific rules regarding the installation of applications and their physical location. It works like and hierarchical structure:
1. If the app has a specified location by the developer, this takes priority.
2. If it is not specified in the app, then the default install location is used.
Android has 3 identifiers for app storage location: that may be mentioned on the application manifest [android:installLocation](http://developer.android.com/guide/topics/manifest/manifest-element.html#install):
* "internalOnly":
>
> The application must be installed on the internal device storage only. If this is set, the application will never be installed on the external storage. If the internal storage is full, then the system will not install the application.
>
>
>
* "auto":
>
> The application may be installed on the external storage, but the system will install the application on the internal storage by default. If the internal storage is full, then the system will install it on the external storage.
>
>
>
* "preferExternal":
>
> The application prefers to be installed on the external storage (SD card). There is no guarantee that the system will honor this request. The application might be installed on internal storage if the external media is unavailable or full, or if the application uses the forward-locking mechanism (not supported on external storage).
>
>
>
Old applications may have no choice but to install on the internal storage, as per the [Google Documentation](http://developer.android.com/guide/topics/data/install-location.html#Compatiblity):
>
> The ability for your application to install on the external storage is a feature available only on devices running API Level 8 (Android 2.2) or greater. Existing applications that were built prior to API Level 8 will always install on the internal storage and cannot be moved to the external storage (even on devices with API Level 8).

What can I do?
==============
You can manage the installed applications and set their storage location, all from one place:
1. Tap "home" to return to your device home screen;
2. Tap your device "menu" button;
3. Depending on your device, you either have to:
* Tap "Manage apps";
* Tap "Settings" > "Applications" > "Manage applications".
4. Now access the third tab where it reads "USB Storage" or "On SD card" (again, varies with the device);
5. Here are listed all the applications that are allowed to be moved to your External Storage, tab over one to bring up more options about it;
6. When the application details panel opens, you have a button "Move to SD card", use it to move that application to your External Storage;
7. Press "back" to return to the list. If you've moved the app to the external memory, you will notice that a green tick is present on the right side on the list, to let you know that the application file is currently on your External Storage.
This is a safe guide to have your OS managing the applications and moving then from Internal Storage to External Storage without hacks or tricks. You can read all about it on the [Google Official Documentation](http://support.google.com/mobile/bin/answer.py?hl=en&answer=168609&topic=29771).

These include:
* apps using widgets (widgets could no longer update if the storage is gone)
* apps using services (these services would break then)
* apps providing sync adapters (these adapters would be inaccessible)
Most of these apps are not even able to be moved to sdcard, as their developers declared them "internalOnly" (see username_2's answer). But some developers forget about this, and so it might happen you move an app which you better had not -- and then wonder about above mentioned things breaking (most users notice this with widgets only). So better keep this in mind as well when moving apps to external storage.
