2012/02/11 | 463 | 1,935 | <issue_start>username_0: One of the things I hate about Android is the folder organization. Each app creates its own folder, usually in the root of the SD card. When I'm trying to find something, I have to search it through long lists of app-specific folders.
Is it possible to reorganize these? For example, this is how I would like my SD card to look like:
* Android: OS specific data
* AppData: Application specific data. This is where every app puts its settings and data, not where they want
* Documents
* Downloads
* Pictures
* Music
* Video etc.
So in other words, can I restrict where apps put their data?<issue_comment>username_1: The fact is that Android is open enough for every dev to do whatever they want. There are some specific places certain stuff goes like the media folder and the .android\_secure folder, as an example. The good news is that you can do a lot of cleaning up yourself by just browsing in there but be careful you don't delete data files and db's for apps still installed.

You can go and delete what ever you want on the sdcard, but it may be data for an application. If you move it, the application will think it has been deleted or doesn't exist, and it will just create the data in the same place again.
Google recommends applications use the /sdcard/Android/data/ folder, but if the application has permissions to write to the sdcard, they can write where ever they want on it. Some applications were created before the recommendations, others may not know the recommendation, and others may not care for what ever reason.
The "standard" is the following for non-application specific data:
Music/
Podcasts/
Ringtones/
Alarms/
Notifications/
Pictures/
Movies/
Download/
and then application specific is:
`Android/data/`

I have downloaded a virtual guitar of size 2.6 MB, but when I went to uninstall this app, then I was shocked to seeing that only 230 KB were freed.
My question is, where are th remaining 2.3 MB? I've searched the phone and SD card but couldn't find out it where it went. It also looks like I've been lost some internal space on the phone.<issue_comment>username_1: I know it sounds smart-ass, but you may need to be a full restart to make the reclaimed space visible again.
Upvotes: 0 <issue_comment>username_2: It could be a cache issue. You could try downloading Astro File Manager and open it. Then go to File Manager > Pref > Cache from there click on Other Internal Caches. beyond that you will probably need to do a factory restore to retrieve all your memory.

Upvotes: 1 <issue_comment>username_3: I think that maybe the remaining 2.3 MB was data in the app. Your phone may say 'deleting this app will also delete all this data' or likewise, but sometimes it doesn't delete the data. So, if you recorded 2.3 MB of songs, this is probably hiding in your device or SD card (if applicable).
I hope this works for you!

2012/02/12 | 527 | 2,002 | <issue_start>username_0: I have been searching for how to properly upgrade to new sdcard, and I did as this posts suggests. [How to upgrade / swap SD card without losing data and installed apps?](https://android.stackexchange.com/questions/15049/upgrade-sd-card).
But when inserting the new sd card several apps (not all) are missing. I had about 80 apps installed, could that explain why I am having this problem, while no other seem to have it?
Could it be, that there are two partitions on the original sd card, one being used for apps when internal memory is full; and I have then only copied the part not in the 'simple' partition?
Using Gingerbread (2.3.3).<issue_comment>username_1: I found out that all the apps missing have an .asec file in the .android\_secure folder on the sd card, however the .android\_secure folder itself is there.
On Linux I wrote:
```
cp sdbackup/* /media/disk -r
```
It copies all folders, and their content, recursively. Except for the hidden folders in sdbackup, e.g.:
```
sdbackup/.android_secure
sdbackup/.doubleTwist
```
Hidden folders in the hierarchy are copied however.
So now I managed by subsequently copying each hidden folder:
```
cp sdbackup/* /media/disk -r
cp sdbackup/.android_secure* /media/disk -r
cp sdbackup/.astro* /media/disk -r
etc
```
And now everything is fine.

To determine allocation unit size on Windows, go to the command prompt, go to the drive letter that the new meida card is on, and type CHKDSK. Allocation unit size will be displayed near the bottom of the results.
To format, in Windows Explorer right click on the drive letter of the new card and then click on Format. It should be obvious from there. The quick format option worked for me.
As for copying files, I had no problem with hidden files. Straight copy worked for me.

2012/02/13 | 938 | 3,859 | <issue_start>username_0: If my phone is lost or stolen, can I remotely and permanently brick my phone. This way, not only is my data secure, but the resale value of the phone plummets to zero.
Tangential question: can apps like Lookout or Prey be disabled by phone thieves?<issue_comment>username_1: It's certainly possible to remote-brick a phone. In fact, you might be able to use [Tasker](https://market.android.com/details?id=net.dinglisch.android.taskerm) in conjunction with [Mobile Odin](https://market.android.com/details?id=eu.chainfire.mobileodin.pro) or similar to remotely softbrick a Samsung device by flashing bad firmware after a text message, or something. Of course these devices are also easy to unbrick; to brick them more permanently you'd need to flash a bad bootloader. Chainfire has said that Mobile Odin can but won't flash bootloaders, so perhaps it could just be modified.
Bad bootloaders can be fixed sometimes if you have the appropriate hardware, but I doubt any petty thief would have it. Most won't be able to fix a softbrick either.
Any app can be disabled, pretty easily too if you know what you're doing.
Importantly, though, I wouldn't do this. All it does is guarantee that you can't get the phone back (you can't track it anymore) or that if you get it back, it won't work. You should just install tracking software instead. Remote bricking won't deter a thief who doesn't know about it, and while I see the revenge aspect it's not as good as catching them!

Both of those will be able to wipe the device but not disable it completely. IF you are on Verizon the phone cannot be activated on another line without it being released from your account. I'm pretty sure that is not the case with GSM phones - they just need to stick a new sim in the phone.
However, both Lookout and Prey will be able to tell you the location of your phone. I believe Prey will also be able to tell you additional information that might help you determine the identity of the thief which you can then pass on to the authorities. They aren't always inclined to act on the information but every little bit helps.

Is there a reason why automatic updates do not work?
Additionally it would be good to know if there was a way to schedule updating of apps or somehow to update a few at one time because updating many/most apps after accessing internet after a long period of time just bogs down system.<issue_comment>username_1: I have seen problems when I don't have WiFi on for a while. Some updates are marked as WiFi-only due to the large size, even if you have turned off "Update over Wi-Fi only" in the Market settings (which I assume you have unchecked).
I think there may be other quirks with the Market app. For example, if you are in airplane mode but have WiFi on, the Market may think you're offline and refuse to work.
It may (or may not) help to switch between having auto-update on globally (in Market settings) vs. having it off but enabling auto-update for individual apps.
BTW I just enable auto-update for apps that I trust and know I won't read the update log for before accepting the update.

In `Settings->CyanogenMod Settings->Input` you can set the long-press behavior of the home and menu buttons, and completely change the behavior of the search button.
What I've typically done is set the search key (or long-pressing the search key) to open up the voice search app. You could substitute the voice dialer or anything else you wanted if you set it up this way, with the trade-off being that you lose the default search functionality (in my case it's okay because I never use the search button).

Download the [drivers from here](http://forum.xda-developers.com/showthread.php?t=1472026) (at the bottom) and install those drivers on the system.
To install the drivers:
1. connect your phone to your pc with USB debugging mode enabled.
2. Windows will not be able to install drivers on its own. So, go to 'Device Manager'. Under 'Other Devices', you will have your phone's name, Spice Mi-350n/Fly IQ260.
3. Right click and select 'Update Driver Software...' and select 'Browse my computer for driver software' and browse to the location where you extracted the drivers and click 'Next'.

Actually the vendor ID in "/etc/udev/rules.d/51-android.rules" was wrong. As I couldn't find the Spice in the Android's developer site.
Executing command `lsusb` gave me the correct vendor id....
```
$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 003: ID 046d:c31d Logitech, Inc.
Bus 001 Device 004: ID 046d:c05a Logitech, Inc. Optical Mouse M90
Bus 002 Device 004: ID 2006:0c03 (-->2006 is the vendor id for Spice MI 350)
```
Now My /etc/udev/rules.d/51-android.rules file looks like:-
SUBSYSTEM=="usb", ATTR{idVendor}=="2006", MODE="0666" GROUP="plugdev"
Now after restarting adb services... i.e.
```
su
$ adb kill-server
$ adb start-server
$ adb devices
```
The output is :-
```
List of devices attached

Now when I launch application from eclipse ide it automatically identifies the device....

Here is the solution that worked perfectly with me:
the problem lies in the DHCP settings of the ADSL router.
FOLLOW THESE STEPS TO SOLVE THIS PROBLEM.......
1. Login to your router and go to DHCP settings (for belkin its 192.168.2.1) and find the item called *leasing time*. The default values of the *leasing time* is usually *Forever* -- and there is a bug with Android
2. All you have to do is to change the value of the *Leasing time* from *forever* to any other long value (depends on the routers options). Here I changed the value from *forever* to *2 weeks* -- and since then I didn't have a single WIFI disconnect.

Basically, I'm interested in SIM unlocking my Huawei U8180, and would like to know if CyanogenMod will unlock the device.<issue_comment>username_1: CyanogenMod - in a vanilla or official build - will not typically contain a bootloader. On many devices there is really no good way to even overwrite the bootloader because it is on protected memory (the bootloader is "locked") and cannot be overwritten. It installs a boot image and a system image (i.e. writes to the `/boot` and `/system` partitions). I've heard that some builds will also come with a recovery image, but I have never seen one that did this.
Unlocking your SIM is unrelated to your firmware, and CM will not perform a SIM unlock for you. [CyanogenMod's wiki itself states](http://wiki.cyanogenmod.com/wiki/What_is_CyanogenMod):

I would further assume that the bootloader on your device does not have any kind of bearing on the SIM lock. HTC allows bootloaders to be unlocked on certain devices, and [their website specifically states](http://htcdev.com/bootloader):

I would guess this is likely similar on other devices, though I'm not specifically familiar with Huawei's hardware or software.

The bootloader doesn't really have anything to do with the SIM lock usually. I don't know of an Android-specific way to unlock this phone, which means you'll probably need to use a paid service, which are generally pretty sketchy. A quick Google shows that some people have had success with [this tool](http://www.dc-unlocker.com/forum/showthread.php?t=4946).

There are a few that support sending video files though.<issue_comment>username_1: **No** there is no federated XMPP Client for Android that supports video calling. Federated because there many proprietary XMPP Clients that do so, but they work only within their own network.
The reason because there is no such XMPP client is pretty simple: Jingle (the XEP which is used for XMPP video calling), is pretty new and most XMPP libraries don't support it yet. This is especially true for the most relevant XMPP library [Smack](http://www.igniterealtime.org/projects/smack/) (relevant because it's a Java library). Smack has some Jingle components, but the development on them stopped years ago and they don't seem up to date.
**Update:** Jingle development in Smack gained some traction in the last months.

* Jitsi - Already covered in another answer, but app is still in aplha.
* [Cisco Jabber for Android](https://play.google.com/store/apps/details?id=com.cisco.im&hl=en) - Never tried this, but appears to support XMPP, though its not FOSS. Also not sure whether it supports federation or is just a walled garden like a zillion other messengers.
* imo instant messenger (Android & iOS).
* Conversations, an open source XMPP (formerly known as Jabber) client for Android 4.0+ smart phones.

```
Scenario:
4 rooted android phones in CyanogenMod (2-Nexus One, 2-Galaxy S2; consider A,B,C,D).
Kernel version 2.3.3 in all the phones
Portable wi-fi hot spot enabled in all the phones.
```
I wrote an application to find the RSSI values of available wireless signals. But as the phones(A,B,C,D) are using wi-fi hot spot, the normal wifi does not turn on. Either wi-fi hot spot can be on, or normal wi-fi can be on.
i.e. If each phone(A,B, C and D) have a wifi hotspot created(AH, BH, CH, DH), then I am not able to use my application, as normal wifi connection needs to be turned on to find the wireless networks.
So I want the phones to scan available wireless networks with portable wi-fi hot spot enabled. Is there a way to do this.?<issue_comment>username_1: What you probably want is your phone work as adhoc and as an AP at the same time I guess it's called bridging
<http://compnetworking.about.com/cs/wirelessproducts/f/apbridgingmode.htm>
I don't think that at first android phones support the adhoc mode at all yet.
<https://stackoverflow.com/questions/1932150/can-android-do-peer-to-peer-ad-hoc-networking>
The bridging is only possible for normal wifi routers not for android phones. Routers also support WDS <http://en.wikipedia.org/wiki/Wireless_distribution_system>
There's no such thing as WDS for android phones yet AFAK.

The answer is basically no. It's theoretically possible, at least with some Wi-Fi chips, but the software needed is fairly involved. Some Android phones do support ad-hoc mode, but bridging is the problem as Sergey indicates. I don't know of anything that's been ported to / written for Android to do this, since it would probably involve altering proprietary drivers (pretty hard without the source code).

2012/02/16 | 628 | 2,597 | <issue_start>username_0: I am very concerned with security of my Google account in case I lose the phone (as in: lose it, have it stolen/robbed, etc.). Right now it seems that whoever grabs my phone will also have full access to mail, calendar etc.
I would be perfectly happy to sync manually and/or have a password prompt every time I try to sync, but I don't see this option.
How can I protect my account? Is screen lock any good? How hard is it to bypass it?
The phone is HTC Desire should it matter.<issue_comment>username_1: Instead of entering a password every time you sync or access your mails - which will also be more insecure, because you enter the password often and in public - think about a **good screen lock** (PIN or Password) and a **[remote wipe solution.](https://android.stackexchange.com/questions/12608/is-there-a-way-to-block-access-to-or-wipe-my-google-data-for-a-lost-stolen-phone)**
Changing your Google account password is always a good idea in case of a stolen Android device. According to <NAME> comment, the device will stay logged in for ~hour and then request a password.
Upvotes: 4 <issue_comment>username_2: In addition to what username_1 says, and I think this is a superior solution:
**Use application-specific passwords**
The idea here is that you can create an application-specific password for any non web-based application that needs your Google credentials (think Android phones, mail clients, IM clients, etc.) You create a credential for each purpose and use this instead of your Google password -- this doesn't require special cooperation by third-party application developers. You can keep track of all issued application-specific passwords, and revoke them on a case-by-case basis if necessary. So if your phone is stolen, you can easily revoke access to your Google account and the attacker will no longer be able to log in as you. Please note that some applications might leave behind contact lists and offline email which will still be on the device even if it's not associated with a valid Google account. You'll need a remote wipe application for this purpose.
You can find this on your [Google Account settings page](https://www.google.com/settings/). Look for authorizing applications and sites, and take it from there. See also [this video from Google](http://www.youtube.com/watch?v=zMabEyrtPRg&t=2m13s) about 2-step authorization and application-specific passwords.
While at it, enable 2-step authorization using your Android device for an extra layer of security when you log in from an unknown computer/device.

I've looked, and I haven't been able to find either an executable or instructions to compile emacs for Android.
I know CyanogenMod has some Unix commands, but I haven't found a list or whether it includes Emacs. I don't want to flash my phone without knowing.
I've seen [many](https://www.emacswiki.org/emacs/EmacsOnAndroid) pages on running Emacs on "Android" via installing Ubuntu. I don't mean running Emacs on "Android" hardware, I mean running Emacs on the Android operating system.
I'm also aware I can use an app to SSH to a Unix box, and that there are online Emacs emulators. Again, not what I'm looking for.
I'm looking for the standard command-line GNU Emacs, and I'm aware I'll need to use a terminal emulator app to run it, as well as a Bluetooth keyboard to do anything useful. I'm not looking for a GUI app, though that would be better than nothing.
I'll accept either a link to a binary or instructions to compile it.<issue_comment>username_1: From what I understand, it is not possible (at the time of writing this), since almost all the dependencies that are required for Emacs to run do not exist on the Android system. Then, even if you got all the dependencies to compile for ARM and Android kernel, it would take longer to start up Emacs than it would to SSH into another machine that has Emacs available.
If you want to try, you can look at [this site](https://web.archive.org/web/20100907032843/http://www.bensin.org:80/haxor/android_native/) which explains what you need to do to compile Linux binaries for Android devices.

2012/02/16 | 1,424 | 5,543 | <issue_start>username_0: I don't know if this is standard ICS behavior or if it's due to my Cyanogenmod based ROM, but every time I open the soft keyboard by clicking on a text box/area a notification appears in the notification drawer that says "Select input method." I don't mind seeing this notification one time, but I'm already using the input method I want and I'd like to disable the notification.
Is this standard behavior for Ice Cream Sandwich? Can it be disabled?<issue_comment>username_1: This is a standard 'feature' of ICS. Aside from the notification, changing input methods can be accomplished through the "language and input" section of the phone menu. If you disable and uninstall all keyboards except for one, so there is nothing else to switch to, the notification may disappear.

2012/02/18 | 566 | 2,436 | <issue_start>username_0: While using my Galaxy Nexus at night in the dark, I started experiencing issues where the screen would flash for a moment to what felt like full brightness when I tap on certain buttons. It seems inconsistent, but frequent. I've had it happen when pressing the back button in various apps, or switching to different apps in the application switcher. It's bright enough to say that it kind of hurts my eyes.
It also seems like certain screens get locked into full brightness. One example is the main timeline screen of the official Twitter app.
I have Automatic Brightness turned off, and the brightness slider at the lowest setting.
Any ideas as to what causes this? Is there some setting I'm missing?<issue_comment>username_1: Strange, i have never heard of something like that, it must be an app which are causing it... Anything you have installed recently? I would try and remove some of the recent installed apps, and see if that works, or make a reset of the phone..

Even when the brightness is at its lowest value, the screen is still bright enough during night to disturb others and hurt my own eyes when reading for long time. This app enables me to reduce the brightness even further the lowest limit. Though this does not neither help you to automatically adjust the brightness nor solve the random sudden increase of brightness.

>

I have about 8 gigs of music stored within Google Music, and I recently got sick of streaming (and risking data charges), so I painstakingly allowed it to be stored offline. So my fresh 16 gig SD card now only had 8 gigs left. Then, I flashed a new rom, thinking that all my music would still be there cached (or however it works), but I was wrong. When I click "show offline tracks only" within the Google Music app, it shows nothing, yet my SD card still only has 8 gigs of space left.
So, my question is, where are these offline tracks stored on my SD card so I can go in and delete them, to free up space so I can back them all up again?
Thanks!
And also, why won't the app recognize that there is offline music stored on my SD card after a new rom is flashed? I figured that data would be untouched across roms.<issue_comment>username_1: Your songs should get saved to `/sdcard/Android/data/com.google.android.music/cache/music`.
The reason they don't appear when you install a new ROM is because the folder they're stored in contains a `.nomedia` file, which excludes it from the media scanner. Google Music is able to keep track of them because it puts entries into its database (which is at `/data/data/com.google.android.music/databases/music.db`) which point to the file. Specifically, anything in the `MUSIC` table with a `LocalCopyType` value of 200 is a song on Google's servers which you've downloaded so it will be "available offline". This disappears if you wipe your `/data` partition when flashing a new ROM. If you have a `sqlite3` binary on your device you can use the following to get a list of all songs that are available offline:
```
# sqlite3 /data/data/com.google.android.music/databases/music.db
sqlite> select * from music where localcopytype = 200;
```
If you want to have your music stored locally across ROM installs, the easiest thing to do is just to create a folder at the root of your SD card named `Music` (or similar) and put the files in it. The media scanner will pick it up that way. Alternatively, you can try removing the `.nomedia` file from the Google Music cache folder. That should allow it be scanned, too, but I don't know if Google Music will try to re-create the file on subsequent launches of the app.
Upvotes: 4 [selected_answer]<issue_comment>username_2: Depending on your device and app version it might also be `/data/data/com.google.android.music/files/music/`.

But also there isn't a way to browse the data files on ios or access the file system. Unless you are rooted, I don't think you have access to where the data files are stored on android either. Either way, you are sort of stuck.
The game data is stored locally on the devices, not on a remote server. They should store it on a server, especially now that the game is available to play on both Google+ and Facebook as well as the mobile devices.
Upvotes: 3 <issue_comment>username_2: I found [this](http://forum.xda-developers.com/showthread.php?t=1353754) thread on xda-developers. If you have jail broken iPhone and rooted Android phone, you can transfer your progress.
Basically you have to copy two files, highscores.lua and settings.lua from /private/var/mobile/Applications/(very long string)/Documents from iPhone and replace them on Android phone in /data/data/com.rovio.angrybirds/files/. You also have to fix permission and make sure you've completed at least 1 level in Android phone before replacing the two files.
If you trust yourself you can also use programs like [Angry birds unlock all level](https://market.android.com/details?id=com.pommedeterresautee.angrybirdsunlock) in Android and unlock only up to the level you've completed in iPhone. But you won't have exact score and hidden star collections. So though little troublesome the earlier way might be what you want.

The TV is a relatively recent Sony Bravia that sadly appears not to support DLNA. I gather the Galaxy Note doesn't support HDMI - so are there any other options?<issue_comment>username_1: Samsung lists the [HDMI Smart Adapter](http://www.samsung.com/us/mobile/cell-phones-accessories/EIA2UHUNBEGSTA) on their website as being compatible with the Galaxy Note.
Upvotes: 2 <issue_comment>username_2: Nowadays there is a plethora of methods to connect a smartphone to a SmartTV.
The following methods can be used:
**Option 1 – Using HDTV Adapter**
This is the certainly most preferred method, considering the fact that Samsung has dropped support for MHL wired cables (from Note 5, if not mistaken- however MHL is a cheaper method for older devices).
Usage
1. Connect one end of a universal HDMI cable into the HDTV Adapter.
2. Connect the other end to the HDMI port on your TV. If your TV has multiple HDMI ports you may use any of the ports. Ensure your TV input settings have the right HDMI port selected. See your TV owner's manual to get more information. (On most TVs you can select HDMI input by pressing the Source button on your remote control and then selecting HDMI 1 or HDMI 2 from the on-screen menu).
Note: Universal HDMI cables are sold separately.
3. Connect your Travel Charger to the HDTV Adapter.
4. Connect your Travel Charger to an approved power source.
5. Connect the HDTV Adapter connector into the Power/Accessory Interface port on your device. This is the same port you normally use to connect your Travel Charger. The TV screen will instantly display what is on your device Home screen.
*Note: most digital rights management-protected content cannot be displayed using the HDTV Adapter. Please ensure the HDTV is compatible with viewing videos or other media stored on your phone using the HDTV Adapter. Refer to your TV owner's manual for correct HDMI settings. Your HDTV may not display an image when connecting the HDTV Adapter to a desktop dock.*

**Option 2 – Miracast**
This option allows you to mirror any screen on your device wirelessly.
1.If you do not have a smart TV that supports Miracast, purchase one of the following items, and connect it to an available HDMI port on your TV.
* [Amazon Fire TV box or TV Stick](http://rads.stackoverflow.com/amzn/click/B00U3FPN4U)
* [Roku 4, 3, or Streaming Stick](http://rads.stackoverflow.com/amzn/click/B015YF5YIS)
* Miracast Video Adapter
* Samsung Smart TV with Miracast support
* Any other device that supports Miracast and connects to your TV
Usage
**Requirements**
* An Android phone that is compatible with the Miracast Technology and
most android versions from 4.2 and above are Miracast or Wireless
Display enabled.
* TV compatible with the Miracast Technology and yes, most of the
latest Television arrives with a Miracast enabled.
Firstly, turn on your TV and change or leave the display to “input mode”
Now, with your Android phone, goto Settings >> Display >> Cast screen
Select “Enable Wireless Display”
Wait for it to search and detect the TV Miracast screen, which when detected, it will show it on your phone’s cast screen.
When it has displayed the TV Miracast on your phone is to select it and your android device screen will then start displaying on your TV screen

TVs, monitors and projectors that support the standard HD resolution have at least one special HDMI port which also provides power; all you need to do is pick up a microUSB to HDMI (passive MHL) cable and plug it in. ( i.e from android phone to TV)
- You can plug the MHL/HDMI cable directly to ports and start enjoying movies without need to copy them with a flash stick.

This method is a cheap, convinient for older devices
---
**Option 4** -**DLNA** (with wired or wireless LAN)
Uses a similar method to miracast, but has slightly different requirements;
* Android DLNA app ( choose one from playstore)
* The TV is already DLNA enabled.
**Steps**
1. Connect your TV(and/or) Android device to a same WLAN network. Under Network settings on TV choose automatic setup, however if it can't detect other devices then use static IP address.
2. Configure your DLNA server ( Android) and select the files/movies and enable sharing.
3. For example my setup looks like this:
[](https://i.stack.imgur.com/q1aa0.jpg)
DLNA android (click image for larger variant)
*Android DLNA media server*
4. After sharing, just go to your TV and select DLNA and you should see your shared movies (Ethernet connection is faster than WLAN connection)
*Remarks: These methods are not just restricted to samsung devices only, but in my opinion any android device with supported technologies*

2012/02/20 | 918 | 3,631 | <issue_start>username_0: I would like to lock my phone with a pin for additional security. Also, I try to minimize my phone usage in the car, but in the event that I do need to call someone, I would like to be able to do so without having to enter a pin. I would like to do this by automated means if possible.
I see two possible directions, but there could be others
1. Use some third-party lockscreen app that supports pin/password/pattern while containing shortcuts to a few apps. I've seen lockscreens that have shortcuts to certain apps, but they don't provide a pin lock.
2. Have a Car Home app that automatically launches when I plug in the headphones. [Car Widget](https://market.android.com/details?id=com.anod.car.home.pro&hl=en) launches on headphone plugin, but it provides access to other screens as well, which I don't want. It has to be headphones though, I don't have a car dock or bluetooth or even a car power cable.<issue_comment>username_1: There are apps available that allow you to distinguish between **locking** your phone and it **idling out**.
For example, it is a good security practice to have your phone **lock** whenever you hit the lock button, but understandable that you don't want it locking 10 seconds after you place it on the passenger seat. You can have the screen **timeout** after 20 seconds, but wait 120 seconds (or more, if you prefer) before it auto-**locks**.
I know that [Juice Defender](https://market.android.com/details?id=com.latedroid.juicedefender&hl=en) provides such options.
----------------------------------------------------------------------------------------------------------------------------
Some apps (such as the music app) have the ability of adding 'widgets' to your lock screen. This is even more apparent on custom ROMS (such as [CyanogenMod](http://wiki.cyanogenmod.com/)), which allow apps to respond to 'gestures' on the lockscreen.
Upvotes: 1 [selected_answer]<issue_comment>username_2: There are programs like Tasker, and llama that can automate things like that for you. But the problem here is how to tell those program that you are inside your car. If the conditions were like time of day, location or battery percentage you could easily use those programs to accomplish such task.
In programs like Tasker and Llama, you can create task so that your lock screen will be disabled when you plug in headphone. But the problem here is, if anyone, anywhere plugs in the headphone your lock screen will get disabled.
Also Sony recently release [NFC tag](http://www.psfk.com/2012/01/sony-nfc-tags.html).
http://www.psfk.com/2012/01/sony-nfc-tags.html">
Maybe you can have one such device in your car and provided that you have NFC in your phone you can just tag it and the lock screen will be disabled. And maybe tag it again before leaving the car to enable the lock screen again.
Upvotes: 2 <issue_comment>username_3: It appears that the way to do this is to use a Car Home/Dashboard type application, such as [Samsung Home](https://play.google.com/store/apps/details?id=com.samsung.att.carhome&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5zYW1zdW5nLmF0dC5jYXJob21lIl0.). When I start this app and don't press the power button - allowing the screen to go off by itself - the pin lock is not activated and I can access any of the functionality on the home screen. This is probably true for other Car Home apps as well.
This isn't completely automated, but I am leery of any automated solution, as it would allow anyone to bypass the lock screen (a possible exception would be car home apps that activate upon a bluetooth connection).

2012/02/20 | 769 | 3,226 | <issue_start>username_0: According to Google, there are some [57 languages/dialects](http://developer.android.com/sdk/android-4.0.3.html#locs) that are officially supported by stock Android. Of course, since Android is open source, there is nothing to stop a device manufacturer, or cell service provider, or even end user from adding support for new languages/dialects.
Now, just because it is possible, that doesn't mean that it has been done, or at least that it has been done on a scale large enough to make an impact. For example, I would likely not spend my time translating my app for a language that 5 people have manually added to their own devices, however if a manufacturer of devices has decided to add support for an additional language that is now in the hands of some thousands of users, that may be a useful translation to make even though it is not officially supported by the AOSP.
So, is there any way to find this out? Or if not officially, is there any anecdotal evidence out there that this type of thing is going on?<issue_comment>username_1: Well, it doesn't *really* answer my question, but upon further reflection, and without any good information available, we have decided to stick to only the officially supported locale list and to just be careful about how we translate for those locales. For example, we will provide two sets of Spanish translations, ES and US, and will be careful to make the US translations appropriate for the wider Latin American Spanish-speaking audience, rather than being US-specific.
Upvotes: 0 <issue_comment>username_2: From prior experience in building AOSP before, the language strings for all aspects of the system, are stored in xml file, found in the AOSP source *framework/base/core/res/res*. Inside that directory in the source, there's *values-XXX/strings.xml* and *values-XXX/do-not-translate.xml*, where XXX is the ISO country code based on the standard guidelines. This gets built and generated into framework-res.apk found in the ROM's live system under */system/framework*.
On an existing ROM, its possible to 'sort of' add translations into it by decompiling it but the effort would not be worth it as the XML data is compiled and "*gets lost in translation*". I say 'sort of' very loosely, as either the outcome would be it may work or it may not work, but the effort would be big and possibly break existing core Android functionality.
You can most certainly add a language add-on for the keyboards but that's about it.
From the aspect of developers, where localization is concerned, the principle is pretty much the same as in the AOSP source. So if the developer wants to add in French language support, he/she can simply create a *values-fr/strings.xml* and shove in there, the french translations and so on. Of course, there will be variants such as Canadian French, Swiss French, for example. So their files, would be *values-fr-rCA/strings.xml*, *values-fr-rCH* to cite the example.
This is where CM has the most languages support and are in a state-of-flux due to users spotting mis-translations etc.
Only Google provides the core languages - such as Italian, French, German, Spanish, English (both US/UK) to name but a few.

I know how to WiFi tether but it is a huge battery hog. Is there a mini-USB version of the Galaxy Tab cable? If so, can it be used to tether?<issue_comment>username_1: There is a bit tricky method suggested by one of the XDA members. Rooting is required.
1. Download & install a Terminal Emulator on your Android tablet.
2. Run the Emulator & enter the following commands:
```
dhcpcd usb1
setprop net.dns1 8.8.8.8
```
The Android phone from which the internet connection is to be sourced must be connected via a USB cable, and then enable USB tethering on that phone.
Now you can access the internet on your Android tablet using your Android phone as a USB modem!
Upvotes: 2 <issue_comment>username_2: Yes! First, attach an OTG cable to your tablet. Then, attach a MicroUSB and connect both devices. Now download one of the numerous apps which make tethering possible and you're done!
If your devices support Bluetooth tethering, you can use it. It doesn't consume too beach battery also. :)
P.S. isn't creating a WiFi hotspot a better idea?
Upvotes: 1 <issue_comment>username_3: I did it by connecting an ethernet dongle to each device and an e-cable to the dongles. I imagine it would use less power than wireless, and I can place the hotspot device away for the best reception.

2012/02/20 | 1,835 | 6,088 | <issue_start>username_0: I am interested in learning how to write to (and if possible, read from) a rooted Android device's clipboard.
I hope to do so using ADB over USB and I am not interested in installing any apps to help me do this, as this is something I plan on rarely doing.
Any suggestions or help guiding me in the right direction would be greatly appreciated.<issue_comment>username_1: Yes, you actually can do this. It's kind of kludgy looking when you inspect the clipboard, but it works just fine.
First off, you can inspect the current clipboard contents with `service call clipboard 1` from an adb shell (or, without shelling in first, `adb shell service call clipboard 1`). It may start out initially blank after a reboot, for example:
```
# service call clipboard 1
Result: Parcel(
0x00000000: 00000000 00000001 00000000 00000000 '................'
0x00000010: 00000000 00000000 '........ ')
#
```
You can put text into the clipboard using `service call clipboard 2`, which basically takes 3 parameters - two ints and the string you want to put on the clipboard:
```
# service call clipboard 2 i32 1 i32 0 s16 "Hi there"
Result: Parcel(00000000 '....')
```
To be honest, I'm not sure what the first two parameters are. [One answer on Stack Overflow](https://stackoverflow.com/a/7582441/390989) has suggested the first int is "number of items in the parcel" (one in this case) and that the second is the length of the string. However, I've used 0 for the second parameter and it works fine, and I can't find any documentation that matches up with this particular function...so take that for what it's worth.
In any case, it's basically creating a Parcel object with 3 fields, then passing it into the clipboard. The clipboard then unpacks the Parcel and sets the string value passed in as the clipboard's contents. You can see this when you go to retrieve the value afterwards:
```
# service call clipboard 1
Result: Parcel(
0x00000000: 00000000 00000001 00000000 00000008 '................'
0x00000010: 00690048 00740020 00650068 00650072 'H.i. .t.h.e.r.e.'
0x00000020: 00000000 00000000 '........ ')
#
```
Similarly, if you long-press on a text entry field and hit "Paste" after doing this, you will get the text that was set via the `call service clipboard 2` line above (and it will look completely normal).
(The above examples come from my HTC EVO, running CyanogenMod 7)

I.e. you will need an app to get clipboard access (read and write) from adb-shell. I use [clipper from majido on github](https://github.com/majido/clipper). The apk is hosted as well, so no need to compile it yourself. When installed you can can comunicate to it using broadcast commands (the app will tell you the exact commands). App does not require root.
Upvotes: 2 <issue_comment>username_4: Here's an improved version of the script by username_2 above. As with that
script, it does not write to the clipboard, but sends input to the
currently focused input field, which is often what you want anyway.
This script is improved to escape special characters to prevent
confusing the Android shell with them. This should allow any string to
be sent unchanged. To prevent the `read` command from interpreting a
(trailing) backslash, I added -r there.
This was tested using the following list of special characters:
```
./adb-send-string ' \`~!@#$%^&*()-_=+[{]}|;:",<.>/?'\'
```
Here's the script:
```
#!/bin/bash
# Send text to android device using adb, emulating keyboard input.
# Based on a script from https://android.stackexchange.com/a/105881/223695
# extended to support special characters
if [[ "$1" != "" ]]
then
TEXT="$1"
else
read -s -r -p "Enter text you want to insert: " TEXT
fi
escape() {
# Encapsulate the string in $'', which enables interpretation of
# \xnn escapes in the string. This is not POSIX-sh, but an extension
# documented by bash and also supported by the Android sh.
echo -n "$'"
# Process each character in $1 one by one
for (( i=0 ; i<${#1}; i++ )); do
# Extract the i'th character
C="${1:$i:1}"
if [ "$C" = ' ' ]; then
# Encode spaces as %s, which is needed for Android's
# "input text" command below 6.0 Marshmellow
# See https://stackoverflow.com/documentation/android/9408/adb-shell/3958/send-text-key-pressed-and-touch-events-to-android-device-via-adb
echo -n '%s'
else
# Encode everything else as \xnn, to prevent them from being
# interpreted by the Android shell
printf '\\x%02x' "'$C"
fi
done
# Terminate the $''
echo -n "'"
}
ESCAPED_TEXT=`escape "$TEXT"`
adb shell input text "$ESCAPED_TEXT"
```

2012/02/20 | 1,052 | 3,355 | <issue_start>username_0: I'm using [GLaDOS kernel](http://rootzwiki.com/topic/14685-19-feb-glados-v115/) which includes the NFS modules (and I'm using the [Codename Android ICS 4.0.3 ROM](http://codenameandroid.com/)) on a GSM Galaxy Nexus. I'm trying to connect to my NFSv4 server (Ubuntu 11.10). My other clients (e.g., Ubuntu 11.04 laptop) can connect over the same LAN network, but my Galaxy Nexus will not connect.
In the Android terminal ([BTEP](http://www.magicandroidapps.com/wiki/index.php?title=Better_Terminal_Emulator_Pro)), in su mode, I'm entering these commands:
```
insmod sunrpc.ko
insmod lockd.ko
insmod nfs.ko
```
lsmod shows the modules loaded:
```
nfs 104232 0 - Live 0xbf036000
lockd 42336 1 nfs, Live 0xbf028000
sunrpc 150792 3 nfs,lockd, Live 0xbf000000
```
My mount command (In the terminal, in su mode) is:
```
mount -t nfs4 nfserver:/shared1 /sdcard/nfs/shared1
```
The error is "no such device". (See edit below - I have a new error now.) It returns immediately, so I'm fairly certain this is entirely a client side error. It is probably not even trying to contact the server.
[Usually](https://help.ubuntu.com/community/SettingUpNFSHowTo) the "no such device" error means that the nfs kernel module is not loaded. However, in my case, it is indeed loaded, as shown above. Can anyone help?
**EDIT**: so now I believe that the BusyBox mount command does not support NFSv4. Unfortunately, my server only supports NFSv4. So I borrowed a NAS device which supports NFS v3 and set that up.
Now the error is "invalid argument". In fact, the BusyBox mount command gives the same "invalid argument" error on all mounts using either "-t nfs" or "-t cifs". That leads me to conclude (based on quote below) that there is a version mismatch between BusyBox and my Linux kernel.
* busybox: 1.19.3-Stericson
* linux: 3.0.8-GLaDOS-V1-15
My conclusion is supported by this [link](http://forum.soft32.com/linux2/Busybox-NFS-mount-problem-ftopict17647.html) where he says:
```
This is how I interpret it.
kernel is newer - recompile mount command (i.e. busybox etc)
Make sure that it uses the headers from the kernel it will run with.
```
Finally, trying a regular NFS v3 server (the NAS device) with Mount Manager does not succeed with either NFS or CIFS. But AndSMB will connect to the NAS using CIFS.<issue_comment>username_1: I can tell you that is is Not the `mount` command, it is the nfs.ko module that probably doesn't support NFS4.
When you call `mount -t nfs ...` the mount command is going to look for the filesystem type of nfs. If it doesn't find it, then you get the `no such device` error. If it does find it, it basically hands off the "mount" to the module.
For the mount manager issue, if you do not have a cifs module, cifs will not work with mount manager. AndSMB uses its own cifs/samaba implementation, and that is fine, but in order to accomplish something that allows any application to access the mounted share, it has to be cifs.ko module. I have to do some more looking in to the nfs issue you are still having.

2012/02/21 | 658 | 2,316 | <issue_start>username_0: I have a **rooted** ZTE Blade with a fast 8 Gbyte SD card (it's **fast** enough, and **partitioned** to 6G + 2G) running on **CM7**, and I'm using [LINK2SD](https://market.android.com/details?id=com.buak.Link2SD), but I'm not perfectly happy with it. Altough, LINK2SD is far better than APP2SD I've used before, and all the apps are now linked to SD card, but somehow, I'm just getting *low on internal space*. I've read somewhere that private data is what remains on the internal storage. How can I kick everything out of that internal storage?
* Can I use [DATA2SD](https://market.android.com/details?id=rappsd.v1) and LINK2SD together?
* What about [Simple2Ext](https://market.android.com/details?id=ru.krikun.s2e)?
Also, I've read that Titanium Backup can install stock app updates to the System partition. (That one thing I haven't done yet, my System partition on internal storage is "too big", I should repartition it.)
Is there a solution for this?<issue_comment>username_1: It's the data that's eating up most of the space, at least on my Lenovo P780. The good news is that the latest version of Link2SD allows you to also move data files to the memory card. The bad news is that if you were already using Link2SD with a second partition formatted as FAT32, then you'll need to reformat that partition to a non-FAT file system (ext2, ext3, ext4, or f2fs). In summary, here's what you'll need to do:
1. Remove all symlinks created by Link2SD. You may need to uninstall some apps if you're running low on internal memory.
2. Use a partition manager to format the second partition on the memory card as Ext2, Ext3, or Ext4.
3. Update Link2SD to the latest version and create the links again.
Upvotes: 0 <issue_comment>username_2: If you are using the Pro Version of Link2SD, then you will be able to move everything of the APP(Apk,Dex,Lib,Data and Cache) onto the second partition of the SD card.And thus you won't be using any internal memory. My Phone has 157mb internal memory and I have apps that would have allredy filled it installed on my phone without losing space.

2012/02/21 | 643 | 2,696 | <issue_start>username_0: The two ways I see to secure an Android phone is through a PIN lock screen or through an app lock program (Password is too inconvenient and pattern is insecure for [various reasons](https://android.stackexchange.com/questions/18763/just-how-secure-is-a-pattern-lock)). The lock screen has the advantage of keeping someone from the phone altogether, but an app lock program can allow me to use basic functionality while locking the apps that I choose such as Email or Package Installer.
Is one option easier to hack/bypass than another? Let's assume that the App Lock program has a helper app that prevents it from being killed (although how well such an app works is worthy of being discussed in an answer - point being it takes a little more work than simply going to task manager and killing it).
I am primarily concerned about data on the phone.
I know that ultimately I cannot rely on either method to secure the phone indefinitely, but to only secure it long enough for me take various actions such as remote wipe, change Google password, Exchange password, etc...
I'm running Gingerbread 2.3.6. For what it's worth it is rooted and has ClockWordMod recovery.<issue_comment>username_1: I would use lock screen... It is easy to use bruteforce on any apps which are using a pin code, it is harden with the lock screen, but not impossible.. So don't carry very important documents on your phone...
Upvotes: 1 <issue_comment>username_2: You could always Encrypt your device.
Depending on what phone you are using will determine the method or even availablity of this function.
It takes time though and you should do it with about 80-90% battery.
Also, I beleive the fact that your phone is rooted, makes it less secure - assuming the thief/person who picked up your phone (assuming that it was to be lost).
As long as they can access the internal/external storage, they can bypass this.
Upvotes: 2 <issue_comment>username_3: The app locker gives you more access, and is working against the system rather than with it. Almost by definition, it's much less secure.
An app locker might keep out the casual user, but not anyone who knows what they're doing. Unless it blocks new apps by default, sideloading would be a problem. Depending on the device that may be enough to root it (if you're not already) and then they can more or less bypass/remove anything on the device. adb access is a risk in both cases but the ability to interact with the device may provide some other options.
I agree with username_2 that encryption is the way to go. Using a lock screen plus an app locker is better than using only one of them, as well.

If you're running ICS, go to settings-developer options instead.
Now when you connect your phone via USB, it will show up as a mass storage device and you can directly copy files to/from the mass storage (and SD card if you have one).
Try placing the certificate in the root directory of your SD card and then import it.

They all show upd now with "Android Logo" icon and not the icon of the program. T-Mobile TV is installed on a ROM, so the icon for that is fine, but take an app "Movies", the icon for that is corrupt and instead of icon of this program, I have a little "android logo" icon. How do I restore all of messed up icons?
Reboot does not help. I tried SD card mount/unmount with no luck<issue_comment>username_1: If you move an app to/from the sdcard, and you have icons on the home screen, you need to remove and re-add the icon to the home screen. when I have done this, I thought the icons removed themselves from the home screen automatically.
When you move it to/from the sdcard, it is a lot like uninstalling the application (without removing the user data) and re-installing it again in the new location.

I have to edit the url with `https://` to load the webpage. Some pages work but most of them just won't load.<issue_comment>username_1: Your issue ain't related with Browser APP, it's a Network configuration regarding the proxy settings.
As you can read from your phone's user manual on page 63:
>
> Proxy settings are used by Browser but may not be used by other apps.

---
Since you've mentioned that only "Browser" gets affected, and that all of them work fine under 3G, this leaves us with an WiFi settings issue:
1. Touch the "Settings" icon;
2. Touch "Wireless & networks" > "Wi-Fi";
3. Touch & hold your network in the list of Wi-Fi networks;
4. Touch "Modify network" in the dialog that opens;
5. Select "Show advanced option";
6. touch "None" under Proxy Settings, then touch "Manual" in the
menu that opens.
7. Clear the proxy box, make sure nothing stays there.
8. Touch Save.
Open the browser and give it a try. You should now be able to navigate without problems either with `http` and `https`.

After I take a picture and then go to add it on foursquare or facebook from picture gallery, the last couple pictures taken aren't there. Sometimes the last 20 pictures taken aren't there or an entire directory of pictures isn't showing up. A lot of times it takes a long time to load the picture thumbnails and directories.
Is there a way to refresh or fix the Picture Gallery or is there a better 3rd party picture gallery that you can recommend?
Should I reformat or replace my micro SD card to make it work faster?
Thanks in advance! :)<issue_comment>username_1: Sounds like the contents of your SD Card have not been scanned since taking the photos. Try the [SDrescan](https://market.android.com/details?id=com.bero.sdrescan) app from Market. This should help in such situations.
Alternatively, you can manually un-mount the SD Card (via `Menu -> Settings -> Storage -> Unmount SD Card`) and re-mount it again. This should trigger the media scanner to refresh the card's contents.

Upvotes: 2 <issue_comment>username_3: I get the same issue with my G2, so I doubt this is a bad SD card.
Another way to force a rescan is to delete the thumbnail folder. I'll use an app like Astro, and navigate to /mnt/sdcard/DCIM. Delete the .thumbnails folder there and the next time you open the Picture Gallery, it will regenerate the thumbnails, including the missing pictures. That said, I think I'll give SDrescan a try next time this happens to me.

The messages still exist, the history is there, but only listed with phone numbers and not my contacts. I have pulled the battery, I have pulled the sim card and battery together and I have restarted the phone. Nothing seems to work. I beleive the contacts are in the phone because under my history some names appear but not all of them. How do I trace /data/data/com.android.providers.contacts/databases/contacts.db to see if my contacts exist at all. Where do I start?<issue_comment>username_1: Maybe your contacts have been swallowed by your google account and are no longer phone-only contacts. If that is the case you can get your contacts back in the "Display Options" inside your contacts/phone app. Just choose to display google contacts and see if they're there.
And, to open a .db file (an sqlite database) you need the proper software ([maybe a market app?](https://market.android.com/search?q=sqlite&c=apps)), some of them are free and easy to use, but I warn you, contacts.db is ugly as hell.

2012/02/23 | 1,199 | 3,830 | <issue_start>username_0: I'd like to know the max cpu speed for the processor on an Android system at runtime. I've seen at least a couple different techniques that result in the current cpu clockrate, but not the max.
Root privileges should not be required.<issue_comment>username_1: After digging through the source that roxan mentioned a bit, it looks like the following in /proc can tell you what cpu speeds are available and how much time has been spent in each:
`/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state`
However, it does give some other states that aren't appropriate. For example, on my Samsung Vibrant, I get:
```
1400000 0
1300000 0
1200000 0
1000000 214141
800000 40092
400000 25273
200000 6159308
100000 389
```
But the chip's standard clock is 1 GHz. So it looks like it should be fairly trivial to find the highest listed speed that has a non-zero time to it.
For my purposes, this should be very adequate.
**Edit:** I've observed that sometimes the order in which the frequencies is listed can vary, so you'll want to iterate through the whole list and find the fastest (as opposed to stopping at the first non-zero).
**More Edit:** Here's a function that works for me:
```
/**
* Get max cpu rate.
*
* This works by examining the list of CPU frequencies in the pseudo file
* "/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state" and how much time has been spent
* in each. It finds the highest non-zero time and assumes that is the maximum frequency (note
* that sometimes frequencies higher than that which was designed can be reported.) So it is not
* impossible that this method will return an incorrect CPU frequency.
*
* Also note that (obviously) this will not reflect different CPU cores with different
* maximum speeds.
*
* @return cpu frequency in MHz
*/
public static int getMaxCPUFreqMHz() {
int maxFreq = -1;
try {
RandomAccessFile reader = new RandomAccessFile( "/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state", "r" );
boolean done = false;
while ( ! done ) {
String line = reader.readLine();
if ( null == line ) {
done = true;
break;
}
String[] splits = line.split( "\\s+" );
assert ( splits.length == 2 );
int timeInState = Integer.parseInt( splits[1] );
if ( timeInState > 0 ) {
int freq = Integer.parseInt( splits[0] ) / 1000;
if ( freq > maxFreq ) {
maxFreq = freq;
}
}
}
} catch ( IOException ex ) {
ex.printStackTrace();
}
return maxFreq;
}

Clearing the cache, history, form data and everything else doesn't do it. Resetting the browser to default settings doesn't do it. The website (served from the local network) doesn't show up in Website settings either.
The only thing that does work is deleting ALL data from the phone by resetting it to factory defaults.
Is there an easier option, and how come this isn't done as part of clearing cache which should "clear locally cached content and databases"?<issue_comment>username_1: Try: `Settings` → `Applications` → `Manage Applications` → Select `Browser` ("`All apps`" tab) → `Clear Data`. This would delete all the data belonging to the app. Quite like a factory reset, but just for that app.
Be careful while using this. Make sure you select the correct application (Its called '`Browser`' some phones and '`Internet`' on some) in the `All apps` list.

2012/02/23 | 745 | 3,090 | <issue_start>username_0: I brought a new Samsung Galaxy Y inbuilt with Android 2.3.5 some month ago and sold it recently. But after selling I noticed that in that Android I left my email ID (email ID that is used to log in to android for the first time).
I don't worry about the my email ID as I have changed its password but **Can I locate my android device with that email?** or by any other way? on any Google Maps like service?<issue_comment>username_1: No, you would need an application like "[Where's My Droid](https://market.android.com/details?id=com.alienmanfc6.wheresmyandroid&hl=en)" installed on the device and know the phone number for the device.
If you sold the device, the new owner probably did a factory reset on the device so your information is no longer associated to the device.
In the future, before you sell your device, you should go in and do a factory reset so you are not giving the device away with any of your information.
I want to add my opinion on these apps that claim to help you find your device (including "Where's My Droid") if it is lost or stolen. They are great if you lost your phone in your house (or somewhere "safe") but if you lost it at like a bar or if someone actually stole it, chances are you will not even be able to use this software. A factory reset can be done on any device rather quickly, which would remove your "locating software" and remove any "tie" that your accounts may have to the device. Also, they require the device be ON, so if someone does steal your phone, all they have to do is turn it off, and when they have a chance, do a factory reset. My best advice I can give you is to remember that these are ~$600 devices (what you will pay off contract, or for a replacement) so treat it like it is a ~$600 device and don't leave it laying around. I am not saying that I would ever take someones phone or anything, but I could have the device factory reset by the time I got to the door to leave. It is as easy as `Menu -> Settings -> Privacy -> Factory Data Reset`.
Upvotes: 4 [selected_answer]<issue_comment>username_2: As username_1 already pointed out, the new owner probably did a factory reset when they bought the device. However, it is indeed possible to locate it if it is still connected to the account, with an application such as Lookout's [Plan B](https://market.android.com/details?id=com.lookout.labs.planb). According to its description, it can be downloaded from the Android Market online directly to the device (if still connected to your Google account) and would upon installation send an email to your email address.
**DISCLAIMER:** I do not in any way, shape or form actually encourage you to do something like this, and though I assuming you asked this as a hypothetical question, I can't understate that this is ethically wrong to do, and possibly also illegal in some areas without the owner's consent.

If you specify your question a little bit it might be easier to answer. You can both erase files and format partitions straight from the terminal. You remove files with `rm`, for safe deletions there's also `shred`. If binaries are not on your phone, you should be able to just install them to `/bin/` or `/usr/bin/`
Formatting in Linux can be done for example with the `fdisk` command, some more info on that [here](http://www.ehow.com/how_1000631_hard-drive-linux.html), or as always you can do `man fdisk` (probably not on the phone terminal though as manuals might not be included).

2012/02/24 | 473 | 1,737 | <issue_start>username_0: I've installed a malicious app that is posting ads over my notification bar, but can't find it. I know the java package name for it: `com.letang.game103.en` using the command: `adb shell dumpsys notification`.
As you see the name of the app is not obvious from the package name. I want to find which app it is, that uses this package name. I also want to report them to Android Market, after leaving a nice feedback for them there!
I've looked at different dumpsys commands:
```
adb shell dumpsys [something]
```
But so far wasn't able to get apps based on their package names.
Is there any way to do this?<issue_comment>username_1: The easiest way, without using any specialized tools is just to visit that app's page in the Play Store (website, not app).
All apps in the Play Store have their package name as part of their URL, so you can just take your package name and prefix it with `https://play.google.com/details?id=` to get
<https://play.google.com/store/apps/details?id=com.stackexchange.marvin>
where `com.stackexchange.marvin` is the package name which will take you to the page for Stack Exchange Android app.

Install App Manager from [F-Droid](https://f-droid.org/en/packages/io.github.muntashirakon.AppManager/). Launch it, start searching your package name using the search/lens icon and your app would show up.

superuser still exists on my phone
1. how do I get my linked apps to become visible and usable?
2. my Android Market has the (killing me) "starting download" forever (and I don't have GTalk, Google Talk that I was told I need to resolve this.) I've tried both wifi and SIM data connection
I've tried clearing market cache+data and nothing
I can't access my memory card because I can't download link2sd and I cant use the Market.
I want my phone to show my linked apps and for the market to work
If you need more info please don't hesitate to ask...<issue_comment>username_1: Are you running a custom ROM on your Xperia x10 mini? If you are missing the Google Talk app, this means that factory rest deleted some of the Google apps required for Market to work properly. I would suggest finding the appropriate GApps package for the ROM you are running and re-flashing it.
Upvotes: 1 <issue_comment>username_2: What i done is i found a programme called "Android injector" which installs .apk files from your pc to your android. Downloaded and installed the google apps and that sorted the market problem out. but i ddnt get to keep my old apps after i got link to sd it was blank. oh well....
Upvotes: 0 <issue_comment>username_3: Sounds like the factory reset removed the changes that link2sd made. but if you now moved apps that are system apps (like talk) they are now "gone". I am not 100% sure how link2sd works, if it uses an ext3 partition on the sdcard or what exactly it does. But it sounds like it really botched up your system.
Your best bet at this point it to [find the Stock ROM](http://forum.xda-developers.com/showpost.php?p=9067949&postcount=1) and reflash the device back to the original stock setup.
For future reference, a factory reset does not return the device to "stock setup", it deletes all the user data off the device, as if it has never been used. It does not add any system apps or reset their "state". If you make those kinds of changes, a factory reset does not fix them.

2012/02/25 | 439 | 1,757 | <issue_start>username_0: I just upgraded my samsung galaxy SL to gingerbread 2.3.6
After that, everytime my data packet is automatically activated all the time.
I switch off my mobile network data and lock my phone, and then switch it on again/unlock, the network data are automatically enabled.
I ve noticed, that when i un-tick/deactivate "use packet data", lock my phone with power/lock button and then unlock it, this option is ticked again (= data are enabled).
Please advise.<issue_comment>username_1: Maybe a factory reset will solve the problem, or if your phone is rooted and you have a custom recovery, then clear the Dalvik cache.
Upvotes: 0 <issue_comment>username_2: Install [CatLog](https://play.google.com/store/apps/details?id=com.nolanlawson.logcat) to check what's happening at the time of unlocking. Without logs, its hard to tell how to fix it.
Factory reset is the last option (not applicable if your firmware is broken).
If factory reset is unable to fix it or you don't want to do factory reset, install third-party apps which could turn off data by renaming APN. I'd recommend [Widgetsoid](https://play.google.com/store/apps/details?id=com.jim2) for it. After installing it, add `Data Toggle` widget on homescreen & choose `APN Renaming` as data toggle method from its settings. The bug can't by-pass it, for sure.
Upvotes: 1 <issue_comment>username_3: I had same issue I think. When you power off in gingerbread you get a power off popup confirmation screen. one of the other options shown will reset packet data. if you hit that by accident it will restore the packet data connection. There is an alternative way to stop 3g rather than turning packet data off but its pretty permanent for the mobile network you use.

2012/02/26 | 973 | 3,609 | <issue_start>username_0: Android Market has just updated an app in my device. I liked the update, but its fully different from last version which was also my favorite. So, I want to keep last version too. I have last version's apk thanks to Titanium Backup. But, I can't install it without replacing current one (Android architecture sucks). Is there any way to do this? Hacks etc..
**Note:** I want to keep current version which must be connected with Market to receive future updates.<issue_comment>username_1: You can't do this. Each Android application has a package name, which effectively defines the Java/Dalvik namespace that its classes occupy. You cannot have two packages of the same name installed because it would create overlapping namespaces, which is why it always replaces the old one when you install a new one. The only way you could feasibly do this is if you were able to get the source for the app and change all of the package definitions.
Upvotes: 4 <issue_comment>username_2: You could try repackaging the application. I once installed some edited version of a game and the result was two games. If remember good, package names weren't the same.
Upvotes: 2 <issue_comment>username_3: It can be done, but not simple for the reasons [username_1](https://android.stackexchange.com/a/19937/13391) mentioned.
You need [apktool](https://ibotpeaches.github.io/Apktool/). Refer to [this](http://forum.xda-developers.com/showthread.php?t=707189) guide on how to use it. And [this](http://forum.xda-developers.com/showthread.php?t=997180) on signing the apk after you're done.
You need to modify the AndroidManifest.xml file. Find the line that looks like this:
```
manifest package="com.example.app"
```
and change it to something like:
```
"com.example.app.foo"
```
After you're finished, recompile then resign. To restore your data, try the following via adb:
```
adb rm /data/data/com.example.app.foo
adb push /data/data/com.example.app /data/data/com.example.app.foo
```
Where `com.example.app` is the package name of the original and `com.example.app.foo` is the modified.
There's always a slight chance that the app will break, or depending on the way the app is structured you may receive a dialog every time you change the screen prompting you to choose which app you want to launch, but it's definitely worth a try if you want it badly enough.
Of course, the two apps will not share the same settings and data.

-----------------------
**Method** : Change package name so that android will recognize it as a different app.
No APKtool, no adb, no super user skills needed.
**Tools required**
* PC with JAVA ( Windows, Linux, Mac ) ( JDK 8 prefered )
* [**ApkRename**](http://www.github.com/sjitech/ApkRename)
**Steps**
1. Backup/Download a copy of the desired app (`app.APK`)
2. Transfer to PC
3. On PC download JAVA and ApkRename
4. Change package name by providing, path to APK file and new package name, to ApkRename
5. Sign the APK using ApkSign
6. Transfer the new APK to phone and install it.
**NOTE:** In case any difficulty in signing the APK, use android APK editor app like `Advanced permission manager` and make any edit, press save & install. At this time they will sign the app.

This isn't a keyboard thing since I've tried swiftkey, android keyboard, Samsung keyboard, and swype.
It is an opera thing, since using default browser, the keyboard "enter" is replaced by a spyglass for search or a tick in a circle for "go" as expected.
I've not tried any other browsers.

A trick you may like with SO is to do this multiple times, then manage search engines, click on one of the SO 'engines', and modify it so that you can readily add e.g. `[android]` to your searches.

*I guess it isn't, or those application would be pretty stupid not to support it, but you never know.*<issue_comment>username_1: The only interactions presently supported by app widgets on the home screen are simple click events. So the answer to your question is no, drag & drop isn't available with widgets. The reason the native folders can do this is because they are just part of the launcher activity so can be programmed to do more complex things than the widgets can

You can also control the behavior of the folder after launching an app, such as whether or not the folder stays open.

It is a cheapy one with no official site...
Is there any settings option I could check to see the display resolution configurations?
Is there any other way for it?<issue_comment>username_1: You probably have a diagonal screen size, and a resolution. Use the Pythagorean Theorem on the resolution and divide the result by the screen size to get the DPI.
For example, my Vibrant is 4", 800x480. sqrt(8002 + 4802) / 4 = ~233 dpi.
Upvotes: 3 <issue_comment>username_2: Even a cheap tablet with no official specs normally mentions the screen resolution on the box, didn't yours?
If not, then you could visit a web page like <http://www.whatismyscreenresolution.com/> (there are many other similar websites out there) or install an app like [Android System Info](https://market.android.com/details?id=com.electricsheep.asi) that will tell you your resolution as well as your DPI.
The DPI is just a measurement of how many pixels there are on an inch of your screen, so if you know your screen resolution, you can measure the size of your screen and calculate the DPI from there to get the actual density.

As of the time that I am writing this, I believe that the Gmail picture and the Google+ picture are still separate from each other, but Google+ profile picture, IIRC, defaulted to this image.
I want to add that ICS added the "Me" Contact. From what I know, this contact is tied to your Google+ account, and no one has seem to find a way to edit the info without deleting the contact and re-adding it.

In any case, here's the steps I took that fixed it for me. I am running Jelly Bean, so it may be a little different for you.
>
> 1. Open the gmail app
> 2. Tap the gmail icon in the top left corner and take note of the capitalization of your email address on the top left
> 3. open an email that you sent
> 4. Tap on the place where your picture would be (it should be a picture of the first letter of your first name)
> 5. Tap on your profile picture in the popup to go to the contact details
> 6. Choose "Edit" from the setting dropdown in the top right corner (the 3 vertical dots)
> 7. Change your email address to all lower case (or maybe whatever showed up in step 2. If one doesn't work, try the other.)
> 8. Tap "Done" at the top left.
>

This fixed it inside my email. In order to also fix it in the email list, I had to also do the following.
>
> 1. Go to gmail's "App Info" page. (under Phone Settings -> Apps -> "All" tab for me)
> 2. Tap "Clear Data" once the numbers finish calculating (and ok on the warning popup)
> 3. Open the gmail app and wait for your emails to re-sync
> 4. Enjoy your face you handsome devil.

2012/02/27 | 1,665 | 6,332 | <issue_start>username_0: I know that one of the new features is [WiFi-direct](http://www.android.com/about/ice-cream-sandwich/) for ICS (noted at the very bottom of the page in the link). Is there a way to leverage this new feature to transmit files from one ICS device to another?
This would be useful because the WiFi speeds would be greater than bluetooth, and you wouldn't need to be connected to a WiFi network or create a hotspot.
The Samsung Galaxy S II apparently has this feature [built in](http://androidadvices.com/galaxy-s2-wifi-direct-feature-high-speed-data-transfer/) pre-ICS (go Samsung!). Is this same method available in ICS? Or is there an app for it?
**EDIT:** Because the galaxy nexus is made by Samsung, and is the only device out with ICS right now, I'm not sure if this "WiFi Direct" sharing (per the link and Ryan's answer below) is built in to ICS vanilla (Samsung did have WiFi Direct sharing pre-ICS, after all).
As such, I've added a vanilla tag, so I'm asking, **is in the vanilla source code to allow a way for users to share files using WiFi Direct? If not, is there an app for it in the market?** I want to know how to do this on all ICS phones, not necessarily just the galaxy nexus.<issue_comment>username_1: Android 4.0 introduces [WiFi Direct](http://en.wikipedia.org/wiki/Wi-Fi_Direct) in to the core of android. it basically creates an adhoc connection between one device and another using WiFi by creating what I guess could be considered an Access Point. You do not need a wifi access point to use WiFi Direct, and actually, if you are connected to wifi when turning on WiFi direct, it will disconnect you. You cannot be connected to both an Access Point and enable wifi direct.
The host device acts as an access point for other devices to connect to, then through other pieces of software, files and other data can be shared or streamed to the client device(s).
To use Wifi Direct, in `settings -> wireless & networks` you have to enable it. Then you should have an option to "share" via wifi. This works a lot like bluetooth sharing, where the other device has to be "ready to accept" your files. You will only be able to do wifi direct with devices that have explicit support for wifi direct. Android 4.0 is the the first version of the OS to have built in support for wifi direct. The Samsung Galaxy S II does have support for wifi direct as well. This was an added feature Samsung put in to their TouchWiz version of Android. While the settings for it are a little different then in Android 4.0, they basically work the same.
There are other devices, like some TVs by Sony, that also have wifi direct support.
Wifi Direct is not hardware specific, its part of the OS. If the device supports wifi then it supports this. It is part of the CORE OS in Android 4.0. Any device that has Wifi and is running ICS, this will work with. Some Samsung devices (I think only the Galaxy S 2) have support for wifi direct even though they are not running ICS. This is because Samsung added the support for it in to their version of Android.
While the Galaxy Nexus is manufactured by Samsung, it does not run the Samsung modified version of Android. It runs a completely "Google Experience" version of Android. The WiFi direct that exists on the Samsung Galaxy S II is different then the one built in to Android 4.0.
[Here](http://developer.android.com/guide/topics/wireless/wifip2p.html) is the android SDK docs that talks about support.
>
> Wi-Fi Direct allows Android 4.0 (API level 14) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi without an intermediate access point. Using these APIs, you can discover and connect to other devices when each device supports Wi-Fi Direct, then communicate over a speedy connection across distances much longer than a Bluetooth connection. This is useful for applications that share data among users, such as a multiplayer game or a photo sharing application.

Here is a screen shot (taken from [this video](http://www.youtube.com/watch?feature=player_detailpage&v=enEBelknmBQ#t=89s)) showing wifi direct setting available on a Nook Color running CM9. The video is at the location where it shows wifi direct working.
Here are 2 screenshots from my viewsonic g-tablet that is running ICS (this is not a CM9 Kang, it is vanilla AOSP android). The first shows the setting, the second shows that i turned it on.
To show that WiFi Direct is actually part of the core of android and not just CM9, here is the source code for the [WiFi direct settings](https://github.com/android/platform_packages_apps_settings/tree/master/src/com/android/settings/wifi/p2p). This is the github mirror of the AOSP. You can compare it to [CM9 source](https://github.com/CyanogenMod/android_packages_apps_Settings/tree/ics/src/com/android/settings/wifi/p2p) too.
Upvotes: 6 [selected_answer]<issue_comment>username_2: There is a reference to the feature in the source code, but with a different name: WifiP2P.

Wifi Direct itself is located in [com.example.android.wifidirect](http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android-apps/4.0.1_r1/com/example/android/wifidirect/), so I don't think it's necessarily included in vanilla OSs, this is just an example on how to use the Wifi P2P API. Someone with more experience in Android source may know better.

2012/02/27 | 1,777 | 6,949 | <issue_start>username_0: The recent apps list in Ice Cream Sandwich added the ability to swipe apps out of the list, thereby dismissing them permanently (and as far as I know this is a vanilla function, not a CM/custom ROM one). The documentation and platform highlights don't appear to cover the under-the-hood workings of this functionality, but I'm curious to know what the system is actually doing.
Further adding to my curiosity, I decided to do a quick test: I started up Music on a CM9 install, then backed out of it. I then checked the recent apps list and saw it was indeed there (and in the proper state, based on the thumbnail). I then went into `Settings->Applications` and force stopped the Music app, but it was still listed in the recent list, leading me to believe it's not connected to processes lingering in the background.
Realizing now that Music may have been a poor choice, I also tested with the USA Today app. This exhibited basically the same behavior, and it seemed like it was forced to "relaunch" after the force stop (which makes sense) though the thumbnail in the recent apps list didn't reflect this (cached, I'm guessing?).
So, what actually happens at the OS level when you swipe an app out of the recent list? Does it simply clear the app's data out of RAM and garbage collect it, destroying its saved state?<issue_comment>username_1: Swiping apps out of the recent apps list is vanilla, and yes, not well documented. This has been the topic of a decent amount of discussion on various Android forums... the consensus seems to be best described [here in some comments](http://www.reddit.com/r/Android/comments/mpevh/id_like_to_squash_this_growing_misconception/c32s7wv "here"): that the behavior is similar to but not exactly the same as closing an app -- in general (for apps that don't define explicit back button handling) it's the same thing as hitting back enough times from within an application that you exit out of it.
The link has some more details on the specifics, but overall you can think of it as quitting the application.
Specific to the Music app, I believe it starts a service, so while the task itself (the Music app/UI) may be closed, the service continues to run in the background so that your music doesn't suddenly stop just because the task got cleared out for memory management reasons. That may have affected what you saw.

If I read these correctly, there are specific handlers for selecting the apps but nothing special for swiping them except for `onDetachedFromWindow()`, which calls `com.android.View.onDetachedFromWindow()` which basically hides the element and clears it's data. This would hint to the fact that nothing special happens on swiping the app, which corresponds with username_1' answer, because since the list doesn't show the active app, the `onPause()` and other system calls that are done when "quitting" an application have already happened.

Just did a little testing with a little selfbuild app. You can test, too.
Heres my testing app: <https://bitbucket.org/username_399/lifecycletest> (download available, too. For those who cant build.)
In every Activity lifecycle method (<http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle>) print the app a log.
You can view it with adb logcat (install Android SDK, cd to platform-tools in cmd / shell and type `adb logcat`. Now you will see, everytime you do something like hit back or home button, the app prints the lifecycle method, mentioned above.)
Your question: If I swipe a app from the recent apps drawer, the `onDestroy` method will be called. It does nearly the same as the back button.
Hope I helped a bit. If there are questions, just ask.

So, it looks like the summary is that swiping an app out of the list will first kill all background processes for the app, then use `onTaskRemoved` to notify the app that the background task was removed. At that point it looks like it's up to the app to decide what happens, so I guess there technically **isn't** a hard-and-fast rule about what happens to the app beyond that point.
Upvotes: 6 <issue_comment>username_5: It closes the app, and its data that is stored in the RAM. Thus, giving you more RAM space so you can run other apps. However, background services are NOT automatically force closed as a result of closing the using app.

2012/02/27 | 345 | 1,409 | <issue_start>username_0: I use the amazon downloader to buy mp3s with my android device. My problem now is that I cannot change the download folder but want the files to be moved to my sdcard. I already found a cron tool to run scripts from time to time. All I need now is a shell script to move all folders (including subfolders and files) from
internalmemory\amazonmp3
to
sdcard\Music
to be honest my knowledge is just good enough to do a "mv" but not good enough to go through all subfolders. I also am not sure about the directory structure of android devices. (pathes to sdcard and so on)<issue_comment>username_1: If you use `mv` on a directory containing files and subdirectories, it will move all of them. But in this case you may not want to move the `amazonmp3` directory itself, so the command would be `mv internalmemory/amazonmp3/* /sdcard/music/`, assuming the internalmemory directory is correct.
The actual names for the internal memory and sd-card depend on the device, for example on my old Galaxy S they were `/sdcard` and `/sdcard/external_sd/`.
Upvotes: 3 [selected_answer]<issue_comment>username_2: Just an addition. "mv" does NOT work on Android because the internal memory and sdcard have different file systems. You have to copy the files and then delete the old ones.

2012/02/28 | 1,591 | 6,521 | <issue_start>username_0: **What I'm looking for:**
Is there a way to make the device claim to be a keyboard/HID when plugged into a USB port and "type in" the contents of the clipboard? More accurately; **What would it take to make it happen?**
**Motivating use case:**
I have a password keeper program on my phone but it's annoying to have to read the password off the device and try to type it into another computer.
**Background:**
I have an Android device that was built before MTP was supported for transferring file but, with recent upgrades, now supports it. Based on this, the USB class that it claims to be can't be hardware defined and must be defined in software.
IIRC, [this project](http://developer.android.com/guide/topics/usb/adk.html) has Android devices (with what I think is a stock kernel) talking as some USB class that was definitively not built in. This indicate to me that you *might* be able to control what USB classes it support without kernel work but I don't know for sure.
As for the Host side (i.e. the PC), I've never seen a PC, Mac or Linux box need special drives for keyboards, even for some rather esoteric devices that claim to be keyboards (bar-code scanners, credit card and smart card readers, etc.) so the generic drivers should be good enough for what I'm wanting.
All that argues that what I'm looking for can be done *from a hardware point of view*, but says very little about what software support exists and nothing about if there is an app for it.<issue_comment>username_1: At a minimum, this would require both software on the phone and on the PC. The 2 pieces of software would have to communicate with each other. Nothing like this, that I know of currently, exists.
And for the PC to think that the device is truly a keyboard, it would require a new driver that would tell the PC that the device is a keyboard, and how "to use it as a keyboard".
I am not saying that it is not possible, because just about anything is possible when it comes to things like this. What I am saying though, is that nothing like this exists, currently.
USB is both hardware and software, if it was software alone, then the same USB driver would work for all android devices on Windows, and this is not the case. USB mass-storage and MTP are handled by the drivers on the PC, not the device. What devices support both MTP and USB mass-storage and at the same time? I have found articles stating that devices can support UMS and MTP, but only support UMS if there is an external sdcard. You cannot mount the external sdcard with MTP and with UMS. MTP is for the internal storage. And I haven't read anything that can confirm or deny that you can use both at the same time.
You don't have to install drivers for keyboards, if they follow the "default" spec because windows already has the drivers for it. There are keyboards that come with their own drivers. As I said, it would be possible. I am not sure about how it would be done. It would, almost certainly, require a custom kernel at the very least for it to act like a keyboard and no additional drivers to be needed on the PC side.
Additionally, I agree with @username_2 that it is possible and I have already said that it is. The problem with a question asking if something is possible, does not ever solve the problem. It would be like me saying "is it possible for me to run ios applications natively on windows?". This is theoretically possible, but there is nothing that does this now and there is not something that a "normal user" (or even an advanced user) can do to make this happen. This site is geared for users, so saying you just need to write a modified kernel is not an answer that is going to benefit anyone. So the real answer to the question is no, because there is not a modified kernel out there.
Upvotes: 0 <issue_comment>username_2: Yes. This is definitely possible, requiring no modifications or drivers on the PC. As the OP mentions, the USB identification on the phone end is ultimately done in software (in this file <https://github.com/android/kernel_msm/blob/android-msm-2.6.35/drivers/usb/gadget/composite.c>), and it could be modified to identify itself as a standard USB keyboard.
This change would require a couple of things.
1. A modified kernel with a patched USB driver
2. An Android app that could talk to some interface exposed by the modified USB driver.
There is a paper that was published in 2010 titled [*Exploiting smart-phone USB connectivity for fun and profit*](https://dl.acm.org/doi/10.1145/1920261.1920314). It describes using a phone to brute-force desktop login screens. The method they used involved making the phone appear as a USB keyboard.

2012/02/28 | 2,113 | 7,069 | <issue_start>username_0: Is it possible to automatically power on the device once the charger is connected given that the device is initially turned off?<issue_comment>username_1: Kernel is loaded at a later stage in the [boot-up process](http://elinux.org/Android_Booting), so any modifications to it would not have any effect for when the device is powered off.
This functionality really depends on each device's hardware, most likely in the bootloader (more knowledgeable editors feel free to correct me.) For example, my Motorola Atrix 4G phone begins booting up when I connect a charger, while my Samsung Galaxy Tab does not - it displays the "Battery Charging" graphic and requires being powered on manually.
Upvotes: 0 <issue_comment>username_2: For some older Samsung devices, this can be accomplished through [NoMoarPowah!](http://forum.xda-developers.com/galaxy-s2/themes-apps/app-nomoarpowah-charging-screen-t1167608):

You need root and you probably don't want to do it unless you really know what you're doing, since I would expect this to modify important system files.

It looks like this has been removed from the Play Store, but you can probably find the APK hosted elsewhere. (I don't have a trusted link offhand.)
Upvotes: 2 <issue_comment>username_3: The battery charging graphic is displayed by `/system/bin/playlpm` file on Samsung devices.
If you are root, you can edit this file to:
```
#!/system/bin/sh
/system/bin/reboot
```
And be sure to add those permissions to the file:
```
chmod 0755 /system/bin/playlpm
chown root.shell /system/bin/playlpm
```
Your device will now boot when plugged

I used IET\_DEMO's answer, but replaced the file located at `/system/bin/battery_charging` with this code:
```
#!/system/bin/sh
/system/bin/reboot
```
Upvotes: 2 <issue_comment>username_5: So, there are many ways to do so. The most proper one, as always [supported](https://source.android.com/devices/bootloader/unlock-trusty#off-mode-charging) by Google (and more and more by others, e.g. [nvidia](https://www.nvidia.com/en-us/geforce/forums/legacy-products/12/249352/auto-power-on-android-when-the-charger-is-connecte/) from nougat) is this fastboot command
```
fastboot oem off-mode-charge 0
```
Otherwise, you can either hijack the charging binary (not guaranteed to be possible on all devices, but just requires root) or patch your ramdisk (theoretically universal, but will require an unlocked bootloader).
For the first solution, you'll have to find somewhere in your system partition (usually the *bin* folder) where the program in charge of the battery animation and all resides. [Some](https://stackoverflow.com/questions/32977502/auto-boot-from-offline-charging-when-charged-on-sony-xperia-or-disable-offline-c) [common](https://appdictive.dk/blog/android/how-to/2017/04/20/disabeling_offline_charge_on_android/) [names](https://forum.xda-developers.com/showthread.php?t=1187631&page=10):
* Motorola: `charge_only_mode`
* Mediatek: `kpoc_charger` or `ipod`
* Htc: `chargemon` or `zchgd`
* Samsung: `playlpm` or `lpm`
* Sony: `chargemon` or `battery_charging`
* Most(?) AOSP-based roms: `healthd`
Once found, you can just replace it with a script such as that above by IET\_DEMO.
Touching the kernel is instead something I don't feel like explaining and recommending if you don't know what you are doing.
Just for the records then, I'd just like to underline that offline charging exists because the boot process is fairly energy intensive, and especially on older phones without even fast charging the power draw from the system could be higher than that on the plug.
Upvotes: 2 <issue_comment>username_6: `fastboot oem off-mode-charge 0` is the genuine method if your device supports. It's Google's [recommended](https://source.android.com/devices/bootloader/unlock-trusty#off-mode-charging) method but not all OEMs/vendors implement the command in bootloader. Or on some devices it's reset on next reboot. If `off-mode-charge` is disabled, bootloader won't pass `androidboot.mode=charger` commandline parameter to kernel when charger is inserted, so device boots normally.
Otherwise when `ro.bootmode` property is set to `charger` on boot, `init` doesn't continue the [normal boot process](https://android.googlesource.com/platform/system/core/+/refs/tags/android-9.0.0_r1/init/init.cpp#738). Instead limited number of services are started and charging animation is displayed. So you can instruct `init` to reboot the device whenever charger mode is detected. Create a new `.rc` file or edit any existing one:
```
# /system/etc/init/off_mode_charge.rc
on charger
setprop sys.powerctl reboot,leaving-off-mode-charging
```
Or execute `reboot` binary:
```
on charger
exec - -- /system/bin/reboot leaving-off-mode-charging
```
But if SELinux is enforcing, stock policy may not let `init` execute `/system/bin/reboot`. So use Magisk's context (or whatever rooting solution you use):
```
on charger
exec u:r:magisk:s0 -- /system/bin/reboot
```
Don't forget to set permissions on `*.rc` file (`chown 0.0`, `chmod 0644`, `chcon u:object_r:system_file:s0`).
It's also possible to continue boot process instead of restarting the device by replacing `class_start charger` with `trigger late-init` in [`/init.rc`](https://android.googlesource.com/platform/system/core/+/refs/tags/android-9.0.0_r1/rootdir/init.rc#687) file:
```
on charger
#class_start charger
trigger late-init
```
Or by setting property [`sys.boot_from_charger_mode`](https://android.googlesource.com/platform/system/core/+/refs/tags/android-9.0.0_r1/rootdir/init.rc#262):
```
on charger
setprop sys.boot_from_charger_mode 1
```
* This method should work on all devices irrespective of OEM as it doesn't depend on vendor-specific charging binaries like `playlpm`, `battery_charging`, `chargeonlymode`, `zchgd`, `kpoc_charger` and so on.
* Also replacing binaries of important services like `healthd` - which take care of a lot of things related to battery, storage etc. - is not a good idea. In this case if the service runs both in `charger` and `normal` mode, device may get into bootloop.
* On non-System-as-Root devices it's not necessary to modify `/system` partition (e.g. if you don't want to break `dm-verity` for OTA updates to work). Simply unpack `boot.img` and edit `/init.rc` file in `ramdisk`.
* Though unnecessary, it's also possible to execute an `init.d` script from `.rc` file. For reference see [How to run an executable on boot?](https://android.stackexchange.com/a/213623/218526) and [How to power off when charger is removed?](https://android.stackexchange.com/a/214074/218526).

2012/02/28 | 578 | 2,584 | <issue_start>username_0: I have a Samsung Galaxy S (AT&T Captivate) that is rooted. I have various ways to tweak the amount of free RAM the OS leaves on the phone. The default is 48 MB, but I was wondering if I could actually go lower without impacting phone performance. Are there guidelines posted anywhere, or that can be deduced based on knowledge of the Android platform? Or should I trust that the default settings are appropriate? I understand that when it comes to free RAM, more isn't necessarily better, but I understand that there is still a threshold that I don't want to dip below.
I'm running a 2.3.6 Gingerbread based ROM. For what it's worth, I'm running the Zeam launcher.<issue_comment>username_1: In the "linux world", what android is at its core, free RAM is wasted RAM. The system will attempt to use up as much RAM as needed. If more is needed, and there are applications that are no longer requiring the RAM it has allocated, the system will free up the RAM from that application an allocate it to the new application that needs it.
Having less RAM available will not necessarily affect the performance. What will affect it is if it frequently needs to free up RAM on the system for other applications. meaning if there a lot of running applications that are Active, and require the RAM, then you can see performance issues. This is because the the system needs to save the state of the application, free up the RAM and then allocate the freed RAM to a new application.
As for what a "low point" might be, I can't say. I have NEVER watched my available RAM, and never really experienced any performance issues because of RAM. for the record, I have the same device (but the T-Mobile version).
Upvotes: 4 [selected_answer]<issue_comment>username_2: How does RAM on Android work?
First, we need to understand a bit about how RAM works on Android. If you are familiar with Windows computers, you will understand that more and more RAM is usually better and having enough free RAM will be necessary for the system to function normally.
However, according to HowToGeek, with Android, it works a little differently. Android is based on the Linux kernel, an operating system operating under a completely different set of standards than a Windows PC. And when it comes to RAM, it's completely different from Windows: Free RAM is the amount of RAM that is wasted.
So, on Android, you do not need to clean up RAM for other applications to run. The process is automatic and very smooth. RAM is not something you need to think of on most Linux devices.

2012/02/29 | 650 | 2,380 | <issue_start>username_0: I'm a seasoned Linux veteran and recently bought a Samsung Galaxy S2 from T-Mobile. I've been feeling the tinkering bug, so I opted to download the source code from Samsung's site and start fiddling.
My problem is that I've already got ClockworkMod installed on my phone, so I don't want to odin flash a new kernel and thereby corrupt ClockworkMod, so I'm looking for details on how to create a proper ClockworkMod install package (generally/always a zip file?) so that I can test the newly compiled kernels.
My searching on google thus far has brought up naught. The ClockworkMod page seems to be pretty barren of documentation. Can anyone point me to some documentation on the install package creation process?<issue_comment>username_1: The required part of a kernel .zip file looks like this:
```
META-INF
com
google
android
update-binary
updater-script
```
You'll also want to have the kernel `zImage` file somewhere else, easiest if you just have it in the root of the archive.
`updater-script` contains the following at minimum (assumes `zImage` in the root):
```
assert(package_extract_file("zImage", "/tmp/zImage");
write_raw_image("/tmp/zImage", "/dev/block/mmcblk0p8");
delete("/tmp/zImage")
);
```
You can also do things like show a progress bar, print messages, wipe `/cache`, and so on.
You'll want to grab `update-binary` from another kernel package for the SGS2. One at random is attached to [this XDA post](http://forum.xda-developers.com/showthread.php?t=1263838).
I tested this method on my SGS Vibrant without issue, using a kernel from an Odin package and an `update-binary` from another Vibrant kernel .zip. Note that this is perfectly safe as long as you're writing to the correct partition -- for the Vibrant it was `bml17`, for the SGS2 it appears to be `mmcblk0p5` (based on the kernel from XDA I linked above) or `mmcblk0p8` if you're flashing an entire boot image (see comments below). You'll want to verify it for sure. Worst case your kernel doesn't work and you flash a known good one.

2012/02/29 | 878 | 3,354 | <issue_start>username_0: The battery usage screen has an indicator for "Signal strength" that, instead of being blue/black like WiFi, has many colors: green, gray, yellow. What's their meaning?<issue_comment>username_1: I assume that you mean on the graph you get if you go to **Settings** -> **About Phone** -> **Battery Use** and tap the graph at the top? I have a signal strength line there, under the battery level graph that has many colours in it that's labelled "Phone Signal" on my device.
[(full size)](https://i.stack.imgur.com/G029z.png)
The reason it's there is that your signal strength can have a big effect on your battery life. If you have a good, strong signal from a nearby phone mast then your phone will run it's antenna in a low-power mode, whereas when it has a bad, weak signal it will turn up its transmitter into a full-power mode to help ensure that your communication gets out. As an extreme example I know that if I forget to switch my phone into Airplane Mode before putting it in the metal lockers at my sports centre, then I often come back to only a quarter or less of battery charge left.
I can't find an official reference for what the colours mean, the feature was introduced in Gingerbread but the [official Gingerbread manual](http://support.google.com/mobile/bin/answer.py?hl=en&answer=182077) barely mentions the graph and that screen beyond telling you that it exists (p.48 of the 2.3.4 manual linked), from personal experience I know that Red is a bad/no signal, but other than green being a good signal, I don't know the significance of the other colours.
Some internet forum posters suggest these meanings for the signal strength graph, which seems to match up with what I see:
**Red** = No data signal (or possibly no signal at all)
**Grey** = No or minimal (2G/EDGE) data connection
**Olive Green** = 3G/4G connection with light data usage
**Bright Green** = 3G/4G heavy data usage (streaming media, etc)
**Yellow** = No consensus on what this means, but it only seems to show up as a very narrow sliver, and generally only when the connection seems to be changing state (eg from data network to wifi)
This seems to agree with what I see on my phone, that while wifi is on and connected to an access point (so any data should be going through wifi and not the phone network) I only have grey, olive or red in the signal strength, whilst when wifi is off I get the greens in addition.
There is also the indicator in the Android status bar that is normally green, but changes to yellow and then red when it is extremely low, the main battery usage graph follows these three colours with what looks like the same thresholds, but that one doesn't sound like what's confusing you.

2012/02/29 | 496 | 1,901 | <issue_start>username_0: I like to leave GPS enabled so that it's ready to go when I open Maps or certain other location based apps.
However, one app that I don't want to access GPS is Facebook. There is, as far as I can tell, no option within the Facebook app to prevent it from trying to access GPS whenever it starts.
Is there another app or setting I can use which will allow me to leave my GPS enabled, but block specific apps, like Facebook, from accessing it?
***Note:*** I took a look at [this question](https://android.stackexchange.com/questions/186/how-to-make-certain-apps-turn-on-gps-automatically), which suggested using [Tasker](https://market.android.com/details?id=net.dinglisch.android.taskerm&hl=en) to essentially *[whitelist](https://en.wikipedia.org/wiki/Whitelist)* certain apps.

The new permissions model in Marshmallow (Android 6.0) allows you to block specific applications from using location services (which includes GPS) without rooting.
Go to Settings->Apps->"Specific App Name"->Permissions. There is a toggle switch for "Location", which you can use to stop the specific app from using location services.

2012/02/29 | 545 | 2,174 | <issue_start>username_0: The stock contacts app of Android 2.3. *(and older versions)* had a filter that displays only contacts with a phone number, accessible under `Menu -> Display Options -> Only contacts with phones`.
This seems to be gone in android 4. The other display options moved to `Menu -> Settings`, but this one is missing. It's also not under `Menu -> Contacts to display`.
Does anybody know if this option still exists and where it is if thats the case?<issue_comment>username_1: In Ice Cream Sandwich, the old Contacts app was now replaced with the [People app](http://socialtimes.com/android-os-4-0-ice-cream-sandwich-people-app-social-api_b81768). This new app is meant to keep you connected with all of your contacts, not just people you call, and it does so in different ways then the old contacts app, by hooking in to social networks and things like that.
The option to only show contacts with a phone number is not an option in the new People app. But I agree that it should be there, especially when you are searching for a contact when you want to make a phone call.

2012/02/29 | 1,352 | 5,415 | <issue_start>username_0: If my Android device is stolen, will the person who ends up with it be able to get my data by plugging it into a PC and using some trick? Is there anything I can do to prevent this or make it harder?<issue_comment>username_1: In general computing, physical access to a device means all bets are off when it comes to security of data. A determined and knowledgeable thief is likely to either crack the protection, or at the very least copy the contents off the device to try and subvert encryption.
There are several security packages on the Market that can make this job a lot more difficult for the potential thief. These apps can remotely lock the device, wipe its data, and even attempt to "dial home" if the thief was careless enough to let it go online. This will deter most, but the very savvy ones.
Your best bet to safeguard sensitive data is to never have it on the mobile device in the first place. Banking apps that store your login credentials, entering credit card info into web forms on browser, etc. are all points of vulnerability.
In terms of damage control after the phone/tablet is stolen, it's always a good idea to have a list of accounts for apps that are installed, so that you can change the passwords asap. Email, social network apps, etc.
Upvotes: 2 <issue_comment>username_2: If you used full-disk encryption, then your data will be accessible until the device unmounted the encrypted disk (e.g. by rebooting) and discarded the decryption key. If you store your sensitive data in encrypted container, then your data will be accessible until the application closes the container and discarded the decryption key.
If you don't use any encryption, then your data is naked in the wild. Many thiefs are simply interested to sell the phone to make a quick buck and so will simply reformat the phone; but if the thief has a specific intent to steal your data (e.g. corporate espionage, identity thief, etc), then you can assume that they can read all your unencrypted data.
If your phone uses SD card (instead of internal memory), then getting to your data in the SD card is trivial. Getting data in internal memory took a little bit more effort, but is still relatively easy. A turned off device with full-disk-encryption is -- for all practical purpose -- a useless brick for your adversary.
Upvotes: 3 [selected_answer]<issue_comment>username_3: As the other answers already state: *physical access to a device means all bets are off when it comes to security of data* (from [username_1's answer](https://android.stackexchange.com/a/20087/16575)). As this is already made clear enough, I will focus on some counter-measures with my answer.
One thing to make it harder was already mentioned in [Lie's answer](https://android.stackexchange.com/a/20096/16575): encrypting the device will make it harder to access the data. But there are several more things. If you e.g. leave *USB Debugging* on, you make it *easier* for the thief to access your device, so it's a good precaution to keep that turned *off*.
Already named in several answers are several anti-thief apps available on the playstore. There's e.g. [Cerberus Anti-Theft](https://play.google.com/store/apps/details?id=com.lsdroid.cerberus) (one week free trial, then ~EUR 3) which gives you a lot of possibilities, remotely controlling your device to locate and track it, set off a loud alarm, record audio from the microphone, and even remotely wipe the phone (to destroy all stored data). Similar functionality is offered by [Android Lost](https://play.google.com/store/apps/details?id=com.androidlost) (available for free -- also see the video on that app's playstore page). Both are even using a "stealth-mode", so a thief can not easily find and uninstall them. A good thing about *Android Lost* is you even can remotely install and activate it if your phone already is lost -- as long it is still online and connected to your Google account.
Summary
-------
So in short and summed up: Yes, a thief can get access to your data -- but there are means of making this at least very hard, or even limit the time frame he has for his "bad deed". Several things to consider on this background:
* Don't store sensitive data on your mobile device in the first place, if you can avoid it. What's not there cannot be taken.
* Chose secure apps which are proven to encrypt sensitive data (and not store it plain-text). See e.g. viaForensic's [appWatchdog](https://viaforensics.com/appwatchdog) (viaForensics is a forensic company which also keeps an eye on mobile security. <NAME>'s book *Android Forensics and mobile security* gives a good insight on this topic)
* Don't leave *USB Debugging* always turned on in your device
* Consider device encryption
* Consider using an anti-theft app such as e.g. *Cerberus* or *Android Lost* (there are several more with good ratings) which also uses a *stealth mode* and thus is not easily found and uninstalled. In conjunction with this: Act fast and wise if your device is lost (e.g. first try to locate it before doing a wipe: it might very well be you simply forgot it on the kitchen table)
* Also don't forget the "obvious stuff": Don't leave your Andy alone on the pub table while going to toilet, for example :) It's harder to steal it from clothes you're wearing then when lying around or being stored in a jacket hanging on the warderobe.

It is assumed that the middle pin is for letting the phone know it's connected to the dock and launch the needed activities (enable Bluetooth, launch apps, etc.)
Upvotes: 3 [selected_answer]<issue_comment>username_2: Google Play Store says the pogo pins are 5V, digital audio and GND.
So I guess the middle pin is the digital audio and that the phone finds out it is connected to the dock because there is a 5V tension between 1st and 3rd pin.
Upvotes: 1 <issue_comment>username_3: This is an old question, but it's the first Google result for "galaxy nexus dock middle pogo" and I felt it deserved a complete answer for those who might look into it.
I've done a lot of dev work for the Galaxy Nexus, especially with the kernel.
The kernel has code for the pogo pins and is very much in charge of them: <https://android.googlesource.com/kernel/omap/+/android-omap-tuna-3.0-jb-mr2/arch/arm/mach-omap2/board-tuna-pogo.c>
As others have stated, the 1st pin is GND and the 3rd pin is 5V (1st pin being the one closest to the power button). However, there's more to this than just giving power *to* the phone: you can actually take power *from* the phone. This is how docks can function without being plugged in (such as the car dock, which would need some power to run the components responsible for audio output).
The 2nd pin is tricky and confusing to me, but I'll try my best to interpret the kernel's code to explain it; feel free to look at the code yourself as well!
The middle pin does appear to do SPDIF audio output, however it first is used to identify the dock that is attached.
It sends a wakeup pulse of 100ms, and then waits for the dock (or whatever somebody may be trying to build!) to respond (I believe the signalling level is 1.8V, but double check yourself if you're concerned):
The response given determines what is connected. It expects the response to be high --> low --> high --> low.
The length of the first high determines the type of dock: desk (50ms) or car (100ms).
Then the dock (or whatever it may be) goes low, and I *think* how long that low is determines if the phone can draw power from the dock (50ms) or if it needs to give power to the dock (100ms). If the phone is giving power to the dock, it should be like a USB host: 5V/500mA. If it's taking power from the dock, it'd be like connecting a regular charger to the device, so it could be anywhere between 5V/500mA and 5V/1A.
Then the dock goes high again, and this determines if SPDIF audio should be output through the middle pin (50ms) or if it shouldn't (100ms).
Finally it goes low again and the identification stuff is done. There will be a slight delay before it begins to output audio however.

2012/02/29 | 615 | 2,286 | <issue_start>username_0: Is there an adb command similar to "locate" or "grep" that would help me find a file on my Android device?
I'm curious about adb specifically, not a search app.
EDIT: "find" has been suggested, but on my ICS device:
```
hydrangea@turnsole:~$ adb shell find / -name *maps*
/system/bin/sh: find: not found
```
On my Gingerbread device it works, though. (Except I haven't rooted that device so it lacks permission.)
```
hydrangea@turnsole:~$ adb shell find / -name *maps*
find: permission denied
```<issue_comment>username_1: The find command works well in adb shell. The syntax is `find /path -name file_name`. For searching read only areas you will need root. If the find command is not available on your particular device, you might need to install BusyBox (search the Market.)
For example,
`adb shell find / -name *maps*`
will find all files that contain word "maps" across the entire file system.
Upvotes: 3 <issue_comment>username_2: "find" is a command line application which **might be** normally installed as:
1. a binary executable (most desktop machines)
or
2. something small doing many things where one of them is "find"
or
3. might be not available as phone manufacturers don't like users to have too much control over their phones
Most likely you have one branded (ex. samsung) ICS device - manufacturers want to have more control on the device than owner does.
Gain root there, then install busybox.
Device is most likely something called "/system/bin/toolbox" - you could execute "/system/bin/toolbox find" but it is likely to return "no such tool" since manufacturer intentionally removed it from the device.
It is however possible that your device has the feature within its bundled toolbox - but just not "symlinked"... if "/system/bin/toolbox find" would execute the feature then you might use "ln /system/bin/find toolbox" command (I might have messed the order of params). Before executing "ln ..." you must remount device in read-write mode (either by using "adb root" or "su;mount -o remount,rw /system"
Upvotes: 2 <issue_comment>username_3: `find` utility come with BusyBox or another 3rd parts.

Possible uses:
1. Playing games via LAN (e.g., Quake)
2. Allow computers to share files
3. Bonjour (Macs)
4. etc...
Is there any way to achieve this? Any apps out there that will set up a wireless network server?<issue_comment>username_1: I did a quick search for "server" on the Android marketplace, and most of the results seem to be basic file servers, web servers and FTP servers. These will help with sharing files, using your Android device to store the files, but probably not much else.
Here [is one that I found](https://market.android.com/details?id=com.sygem.android.shareme_free&feature=search_result) that supports [UPnP](http://en.wikipedia.org/wiki/Universal_Plug_and_Play) (Universal Plug n' Play), and DLNA (Digital Living Network Alliance), and is designed for images, video and music, and states that Xbox 360 and PS3 are supported, although it doesn't state that you can use it for games on those consoles, and the screenshots don't seem to have anything about games.
Now I'm assuming that nearly all of these apps will require a network to be in place, that is, all devices would be on Wi-Fi with your router (your homehub or whatever you use for all your devices to connect to the web, assuming you don't have a separate modem), so I don't think that these apps will make your Android like a Wi-Fi hotspot, just a server in the sense of a central machine that stores the data that others use. The actual data connections would be via the router, just all going to/from the Android.

Screens on most current mobile devices (resistive, capacitive) can only register touch events. You would need to modify the OS to treat a single tap as a mouse pointer, and double-tap as a "click". However other gestures like scrolling, pinch-to-zoom, etc. would most likely stop working with such a paradigm.
Also, most mobile versions of sites disable the fancy stuff like hover animations anyways, in order to load faster.
Upvotes: 1 <issue_comment>username_2: One way to trigger the hover on links is to long-press the link, wait for the menu to appear, and the press the back button to cancel the menu. This also works in some other browsers.
Note that this doesn't work on all links. Just tried on the example you mentioned, doesn't work, probably because there's a slight delay between the onMouseOver event and showing the menu. But on other pages, where it's a simple onMouseOver trigger this method works.

2012/03/02 | 719 | 3,110 | <issue_start>username_0: What does the `modify/delete USB storage contents` permission really mean? Does it grant access for the application to read, modify and write *all* the data on my USB storage? Maybe it is this only limited to a subset of that data (e.g. only data written by the application itself)? Or does it mean something else entirely?<issue_comment>username_1: Each application has a specific storage folder. But, some folders are public, like the Pictures, Music and Ringtones folders.
So, basically an application can write/delete files from a public folder and from it's own folder.
Take a look at this link for further details: <http://developer.android.com/guide/topics/data/data-storage.html#SavingSharedFiles>
Upvotes: 1 <issue_comment>username_2: If you are familiar with the concepts of read and write permissions on various PC platforms, that is pretty much the same as what is going on here. You are giving the application write access to your "external storage" Which could be an SD card, or some storage space that comes with your device.
That permission indicates that the application is able to create, modify, or delete any files that reside on the SD card (or the non-removable storage space that the the OS treats most like an SD card).
So it could download a file from online and manually save it to your SD card.
It could generate its own image, text, audio etc.. file and save it to your SD card.
It could delete any file on your SD card.
It could find a file that already exists on your SD (even one with nothing to do with the app) and make changes to it.
Upvotes: 4 [selected_answer]<issue_comment>username_3: It means that an application can read/write to the entire contents of your sdcard. Even if the application does not have this permission it will still be able to read from the contents of the sdcard. Giving it modify/write permissions will allow the application to create, edit, or delete files.
99.9% of the time this is so the application can do things like save data to the sdcard. For example this could be images from wallpaper app, or if the app is used to backup your sms messages for you, or even a podcast app needs to save the mp3 file to the sdcard.
There has been some "fuss" lately about ios having access to your pictures and other data on the device. You have to remember that these devices are not Phones, they are computers that make phone calls. It is no different if I install an application on Windows/Linux/OSX, the application will have access to every file on the system that I have access to.
If you don't trust an application to install it on your PC, you wouldn't install it. You should use the same thoughts with your Phone, but keep in mind that you may have even more personal information on the Phone then you would on your PC.

You should see something like "USB\VID\_2207&PID\_0010&MI\_01"
The numbers maybe different based on your device vendor id, for example my vendor id is "2207"
No open the adb\_usb.ini located on the folders below and add your device id in hex format
for example my device id is "2207" I'll put it there as "0x2207"
It is usually located in
1. XP: \Documents and Settings\.android\
2. Windows 7: \Users\.android\
3. Windows 8: I really dont know.
But if the folder doesnt exist try to create it by using cmd. And if the file adb\_usb.ini also doesnt exist you can create it using notepad and only pasting only your device id and save it on the .android folder.

2012/03/02 | 978 | 4,025 | <issue_start>username_0: I have some apps installed on my device and I want to perform a factory reset. Is there a simpler way to re-install my applications after the reset (with the least possible number of user interventions), without having to search them all in the Market and re-install them again one by one?
Rooting is not a problem.
Thank you in advance.<issue_comment>username_1: If you have a 4.x device, the automatic backup/restore found under `Settings -> Backup & reset -> Back up my data` and `Automatic restore` options work fine. It uses Google's own servers to save a list of apps installed on your phone. After a factory reset once you sign in with the same Google account, it gives you an option to restore those apps. Keep in mind that if the goal of factory reset is to change the default Google account, you'll need to first add that account to the phone, and change the `Backup account` to the secondary one you've just added.
On older Android versions the automatic backup/restore was not very reliable, but there are some 3rd-party apps in the Market that can help depending on what exactly your goal is. If you want to simply re-install apps, then [AppBrain](https://market.android.com/details?id=com.appspot.swisscodemonkeys.apps) along with [Fast Web Installer](https://market.android.com/details?id=com.appspot.swisscodemonkeys.apppusher) are great. AppBrain allows you to save the list of your installed apps to their online site, and after a factory reset you would only need to re-install these two apps, sign in, pick the list you created earlier, and it allows you to kick off a process that automatically installs the "missing" apps directly from Market.
If you also need to restore the settings and data associated with those apps, [Titanium backup](https://market.android.com/details?id=com.keramidas.TitaniumBackup) (rooting required) is a better choice. This app backs up all installed apps and their settings/data to your SD Card. After a factory reset you install Titanium from Market, and then do a restore. It can also backup/restore system apps and settings, which can help after a factory reset, but it's generally not recommended to do so, especially if you are planning to install a custom ROM.

I use that and the market goes and reinstalls all the apps I had installed. Sometimes it skips some here or there, for what ever reason, but for the most part it works well. The only problem is no data is restored with these apps. I also use [Titanium Backup](https://market.android.com/details?id=com.keramidas.TitaniumBackup) sometimes for this. The plus about Titanium Backup is that you can also restore the data, you know, so you don't have to redo all those levels in angry birds again.
The first option does not require root, but I don't know if you can change the setting after the initial setup. TB requires root.
Another option, but it is a bit manual and a little more work then the others, but you can go in to the market website and set them to install on the device.

If you see the same error, then follow the steps -
1. Menu > Settings > Personal > Accounts and sync > click on your google account (email)
2. click 'Remove account'. Don't worry, it's not deleting your physical account. Account related information is still saved in Google.
3. Launch Google Play Store again
4. When asked, use existing account to create the google account.
5. Provide your existing google account information (email & password)
6. try again to download

2012/03/02 | 1,060 | 4,086 | <issue_start>username_0: I have a Android tablet for which I want to do a factory reset, and then install some pre-defined applications.
This has to be carried out by someone who has *no computer experience and no Android experience at all*. All I get this person to do is connect the device to a computer by cable, and interact with a very simple interface with a couple of buttons.
All this has to be performed on a well known device and only for that model.
Is it possible to connect a device to a computer and with a couple clicks do all that?
If so, are there any suitable applications which do that already? Would it be necessary to create software for that?
Rooting is no problem.<issue_comment>username_1: Possible solutions, in descending order of idealism and difficulty:
* Create a custom ROM, with the apps you want on it, which you can flash onto these devices. [This question](https://stackoverflow.com/questions/6232620/getting-started-with-creating-custom-roms) is a good starting place for that.
* Write your own app, which automatically installs the other apps. The first answer to [this thread](https://stackoverflow.com/questions/2637957/automatic-install-of-apk) provides the code to install apps programmatically.
* The easiest solution, if it suits your needs, would to be to use [one](https://market.android.com/details?id=com.rhythm.hexise.inst) [of](https://market.android.com/details?id=org.brightapp.installer) [many](https://market.android.com/details?id=com.magmamobile.app.apkinstaller) "installer" apps. If you can drop the apps on the tablets after installing your stock ROM (ideally on an SD card), you could then install an "installer" app. Then either run it yourself, or instruct your users to run it and install the listed apps.
In any of these solutions, you will have to write the desktop computer application which has the few-button interface for users, which does the flashing and installing. Whether you do a custom ROM or a stock one, you will have to automate its install. [This thread](http://forum.xda-developers.com/showthread.php?t=1446054) has some help on automating ROM installation.
Upvotes: 2 [selected_answer]<issue_comment>username_2: I know it's a late answer -- but it does not need any "special app" to be written:
As to your apps installation: Put all the `.apk` files into a directory (you can catch them e.g. using [AppMonster Free Backup Restore](https://play.google.com/store/apps/details?id=de.android_telefonie.appmanager)). Add the basic stuff from the Android SDK (you don't need the entire SDK package, just a few files which you can find e.g. in the AndroidForums [ADB Guide](http://androidforums.com/faqs/443072-adb-guide-updated-12-05-2011-a.html), for Mac, Linux and Windows). Write a tiny Shell/Batch script to `adb install *.apk`.
The factory reset [can be accomplished in a similar way](https://stackoverflow.com/questions/10817721/wipe-data-factory-reset-through-adb):
```
adb shell "recovery --wipe_data"
```
So put that as the first line of your script Optionally prepend it with an `adb wait-for-device`. As the wipe is followed by a reboot, better make it look like this:
```
adb wait-for-device # in case the user starts the batch before connecting the device
adb shell "recovery --wipe_data" # factory-reset (includes reboot)
adb wait-for-device # wait until device has rebooted
adb install com.foobar.myapp # install the apps you want
adb install ...
echo "=========================" # let the user know the process is finished
echo "All done -- Cut the rope!"
echo "========================="
```
Zip it all up and send it to the user.
Instructions to the user:
1. Unpack the ZIP to an empty folder (closer descriptions depending on the OS used)
2. Connect your device with an USB cable (maybe add instructions on how to see whether the connection was established successfully. On windows, added trouble might be special drivers needed)
3. Start the Shell script/Batch file
Taking a look at the ADB options might give you further ideas ;)

Bonus point if it can connect via Bluetooth to my Linux-based PC.<issue_comment>username_1: You could simply use a bluetooth/wifi mouse app like [PRemoteDroid](https://market.android.com/details?id=org.pierre.remotedroid.client). There are [a bunch of others](https://market.android.com/search?q=bluetooth%20mouse&c=apps), and generally speaking they just allow your device to be used as a mouse/keyboard input. If you can pair with your PC it should work, although I've never tried it myself (I do use PRemoteDroid to pair with and remotely control my Xoom, though; works great).
Another option would be some kind of [VNC or remote desktop client](https://market.android.com/search?q=vnc%20client&c=apps), but that's not as lightweight and some of them don't support Linux (Splashtop, for example, doesn't have a Linux server, IIRC).

It doesn't require phone and computer to be on the same network (as long as both have Internet it will work).
You control the slides by using the volume buttons, so you can switch the phone's screen off (easier to handle without hving to look at the phone, and less risk of unintentional clicks).
Additionally, if you have a Android Wear device, it lets you control the presentation with wrist gestures.

2012/03/02 | 477 | 1,766 | <issue_start>username_0: Rest of the error message: "Please try again later. If the problems persists(sic) please visit the Netflix website."
I successfully used Netflix streaming video for over a week on my new Xyboard 8.2. Suddenly, in the middle of a show, it started giving this error (and stopped streaming).
I tried other shows and different connections (WiFi and 3G). I uninstalled and re-installed the updates to the factory version several times. Rebooted several times. Called Netflix, who said I should contact Motorola and re-install from scratch. Rooted the Xyboard instead and installed from scratch. No change.
Netflix doesn't even think Xyboard is a supported device, although Motorola advertises it for the Xyboard. The tech said they haven't gotten a rash of calls about this error.
All but the "1009" in the error messages seems to have occurred many a time on other devices with lots of weird resolutions that don't seem applicable and the few I've tried.
Any additional suggestions?

An export set is selling $100 less but was told that it does not support messaging in Chinese. My question is whether messaging input language is supported by Android or by the handset maker, <NAME>? If by Android, do I need to root handset and update firmware directly from Android? If by maker, then I need to go to the maker for the language pack. Is it worth the trouble to save on $100?<issue_comment>username_1: Do you ask wheather your keyboard will have Chinese input?
Best part about Android is, that you can easily change the stock keyboard with whatever you like. You just install it like a normal app, and select is as input method. Bulgarian is supported, not only keyboard layout, but even text prediction. I am pretty damn sure there are some good keyboards that will provide Chinese for you. Smart Keyboard Pro (I think) has one, you might check its features in Android Market. You can probably find text prediction in Chinese, do a search in Android market, too :)
If you want the whole ROM(menus,etc) to be in Chinese, though, this is ROM dependent, so it is not easy to change this, you will have to root.
In short: A good keyboard will cost you 5-6$, so you are saving 95 :) I hope I understood you question correctly.

Thanks for your help.<issue_comment>username_1: The device may have to be unlocked first. Rooting will not Unlock the device. You will also need information from the network you want to run the device on. Like if the device is supported on their network, if they are able to active the device (they will be able to tell you if they support it if you give them the ESN/MEID) and what their mobile carrier code is (SID/NID/MCC).

CDMA unlocking is also more difficult than SIM unlocking a GSM phone, and CDMA phones need to be activated on the network, unlike sticking a SIM in an unlocked GSM phone and doing whatever you want. You'll need help from both carriers (Verizon to unlock, your carrier to activate) in order to do this.

Some of them require editing. The problem is I don't know which path contains these scripts.
Does anyone here know that? Or know where the firefox data is stored?<issue_comment>username_1: As with all apps, they store their data below the `/data/data` directory, in a directory named according to their package name -- which is what you can see following the "id=" in the playstore URL. So for Firefox, data should be in `/data/data/org.mozilla.firefox`.
So far the good news. Now for the bad news: This directory can only be accessed by the app itself -- or by the root user. So if your device is not rooted: bad luck.
I could imagine that for userscripts and some other profile data, Firefox *might* (or might not) use some storage on the sdcard -- so you could check if you see a similar directory structure there. Certainly not with the "doubled" `/data`, and maybe even just named "firefox" -- as I do not have Firefox installed, I cannot check, but it's worth a look.
Upvotes: 2 <issue_comment>username_2: As username_1 says, all the data are in `/data/data/org.mozilla.firefox`, which means you can only read them if your device is rooted. Inside that directory, the path `files/mozilla` has a very similar layout to your `~/.mozilla/firefox` directory on a Linux desktop: it has a `profiles.ini` and a directory `asdf12yz.default` containing all the interesting files.

You can use a 3.5mm male to male cable and connect the other side of the cable in the Line in port (which is often marked as the blue 3.5mm port).
This way you can stream the audio/video on your phone and record it with a recording software like audacity on your PC.
This is not the original audio. This involves converting the digital to analog and back to digital again.
If you can't, for some reason stream near your PC you can make a custom TRRS jack which will feed the audio output back to your mic pin and record it with your phone. ~~I'm not entirely confident this will work.~~ I've tested it and it worked.

How do I activate my front facing camera in my Galaxy S? It's up to date on software according to the US Cellular store, I brought it in for an update not long ago
(I'm running hardware version I500.04, it's model number SCH-I500, firmware version 2.3.5, and kernel version 2.6.35.7, not sure what's necessary)
When the camera, skype, or YIM is open, there is no option to change camera display. I'm not sure what to do, because it appears to have a front facing camera installed.
Does anyone have advice? I've looked around, but haven't been able to find an answer that truly answers my question.
So...how do I activate this camera? It's a large part of why I bought the phone.<issue_comment>username_1: Open pre-installed Camera app & tap this icon to switch cam:
Same icon is found in [Camera360 Ultimate](https://market.android.com/details?id=vStudio.Android.Camera360) (my fav) to switch cam.
Front-facing cam is automatically activated during video calls over 3G (if you are using pre-installed Dialer app).

After reading the above answer and the other replies not being of help , I just stated digging around. Sure enough what I cound was while in shoot mode I hit the menu button left of home and it listed only "change icons" or something like that. Up came a screen if icons one of which was the change-camera icon that had gone away! Just like any desktop icon, holding it down and dragging it to the location I wanted it in was the trick.

For example, FB all of a sudden asks my GPS data or reads my contact list, without me launching the FB app. FB does not have a persistent notification icon, so I do not expect it to be a background process. Yet using Intents, apps do what it wants when it wants.
I want to be able to know -- then stop or control -- what apps launch by themselves in my device. I hope that's a fair thing to ask.<issue_comment>username_1: The only real way to control these apps is to remove them. Android doesn't provide any fine-grained settings to control the odd behaviors of individual apps.

Make sure you've [Busybox](https://play.google.com/store/search?q=Busybox&c=apps) installed and use `Advanced Mode` of Autorun Manager. It displays all receivers of an app as well as intents to which receivers are registered. From there, you can disable a receiver of an app, too. But, you'd need [pro version](https://play.google.com/store/apps/details?id=com.rs.autorun.pro) if you want to disable more than two receivers.

I don't use the camera much, but I think I had auto focus when I first started using the phone. Now I have to manually focus by tapping the screen.
I'd rather not clutter my phone with 3rd party apps for camera since I don't use it much, but I'd like to have AF for my random quick snaps.
Any tips?<issue_comment>username_1: Try this, Go to Settings -> Apps -> All Tab -> Camera -> Clear data.
Upvotes: 1 <issue_comment>username_2: Did you try resetting the settings to defaults and rebooting the phone? There is a reset option in the camera setting menu (open camera, the setting knob, then the three dots, restore defaults). If that doesn't work, then go to system's Settings, Applications, "all" tab and clear data.
Upvotes: 1 <issue_comment>username_3: These suggestions might seem odd and they might not yield any results but they're worth a shot:
1. Try using the panorama and video settings in the stock camera, and I do mean actually use them. Don't just switch to them and switch back to picture mode. If you're lucky changing modes, taking a panorama/video, then changing back to normal picture mode will reset whatever needs to be reset.
2. In normal picture mode long-press the shutter button. Try this twice, one time release the screen as normal and the next drag your finger away from the shutter button before releasing the screen. I'm not sure if doing it these two ways will have different results, but I know that if you drag your finger away no picture will be taken.

It's entirely possible that you have a hardware failure.

Once I found this setting I found that if I set it back to Auto (or Macro if you want to do a close-up) that the auto-focus starting working again.
Hopefully this helps someone.

2012/03/05 | 849 | 3,146 | <issue_start>username_0: I bought a new tablet, but Android (2.3.1) shows that it has only 150MB free of 256MB, and it should have 512MB.
I checked the file /proc/meminfo, MemTotal information. It only shows 256MB.
Is there a possibility that the Android "hid" 256MB of RAM from the user?<issue_comment>username_1: This is not uncommon in the embedded world. A prominent example is the [Samsung Galaxy S](http://en.wikipedia.org/wiki/Samsung_Galaxy_S), which is advertised with 512MB RAM. But only 300 something are actually available for the OS. I believe the other part is used for the (powerful) GPU.
This leads to effects where a similar device is faster. For example the HTC Desire/Nexus One both have 512MB (576MB for the Desire) and overall play in the same league as the Galaxy S, but IMHO they are in many situations faster then the Galaxy S. But I am not sure if it's because of the "crappy" stock ROM of the SGS or because of the RAM difference.

That is quite a common thing among cheap Chinese devices, two scenarios spring to mind:
1. The kernel is built with a memory model that is split up into two, half of it is occupied by the kernel, the other half is occupied by Android, otherwise known as a 2G VMSPLIT, 2Gb addressing space for kernel, 2Gb addressing space for Android and user apps.
2. The chip-set controller for accessing the RAM is "locked down". There are ways of "unlocking" the chip-set controller but sadly, that information is very difficult to obtain. There is a tool available which, I must add, very difficult to use and is not exactly friendly either, PSAS IIRC or one of the variants of it.
I can cite one handset that has this problem - Zte Blade, there's two variants of it, Chinese variant (which has 512Mb with only 256Mb available, the rest locked out), and the European variant which indeed has 512Mb - albeit limited and depending on the region within Europe.
Unfortunately, for some obscure reason, those chip-sets used on the circuit board could be either refurbished with the remainder of the RAM "locked down" or is a cheap clone of the real thing.
There was various reports on Modaco about this in trying "to unlock" the remainder of the RAM in the Chinese (and some European) variants of the Zte Blade, but IIRC, it was not successful.
The only thing that can be done to compensate, is either, roll your own kernel using VMSPLIT 3G, and flash it or, do some searching on the internet to find out if anyone has it unlocked and what steps are necessary, IIRC the tool used was PSAS which actually can talk to the chip-set - have heard some hard-core hackers using it to modify and alter the handset in that fashion.

Memory editor tab - menu - memory dump - select range and folder - press ok - wait for toast "Dump end".
Here some video examples how to do this:

2012/03/05 | 363 | 1,289 | <issue_start>username_0: I'd like to use my HTC Evo 3D as an external monitor for my Canon 7D camera. The Canon 7D has a HDMI output. It also has an USB port, naturally.
I was wondering whether this would be possible. I think the USB/MHL port on HTC Evo 3D is for output only and it cannot receive any signal inputs. Is that right?
That would leave the USB port for this. But I still don't know how to achieve it.
I want to achieve something like this:
<issue_comment>username_1: As far as I know, there are several apps on google play that will support several external cameras via USB, and I believe they allow for control of camera via android as well. Just search for Canon Camera Controller.

Then you can plug your 70D using a mini USB cable and then plug it in to the OTG cable and plug it into your phone. Then you can download an app such as [DSLR Controller](https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller&hl=en) and you should see live feed of your 70D on the phone.

Is there a way to force the devise to shutdown immediately?<issue_comment>username_1: There is no "force shutdown" as far as I know, but you can force a reboot by holding down the power button for about 15 seconds.
