Set to true if you want to show library debugging. @param debug True turn on all logs for this library to be printed out to logcat. False turns off detailed logging.. This is a convenience method that calls setLogger to a verbose logger and enables verbose logging.

This method notifies the beacon service that the application is either moving to background mode or foreground mode. When in background mode, BluetoothLE scans to look for beacons are executed less frequently in order to save battery life. The specific scan rates for background and foreground operation are set by the defaults below, but may be customized. When ranging in the background, the time between updates will be much less frequent than in the foreground. Updates will come every time interval equal to the sum total of the BackgroundScanPeriod and the BackgroundBetweenScanPeriod. @param backgroundMode true indicates the app is in the background @see #DEFAULT_FOREGROUND_SCAN_PERIOD @see #DEFAULT_FOREGROUND_BETWEEN_SCAN_PERIOD; @see #DEFAULT_BACKGROUND_SCAN_PERIOD; @see #DEFAULT_BACKGROUND_BETWEEN_SCAN_PERIOD; @see #setForegroundScanPeriod(long p) @see #setForegroundBetweenScanPeriod(long p) @see #setBackgroundScanPeriod(long p) @see #setBackgroundBetweenScanPeriod(long p)

Configures using a `ScanJob` run with the `JobScheduler` to perform scans rather than using a long-running `BeaconService` to do so. Calling with true on devices older than Android L (5.0) will not apply the change as the JobScheduler is not available. This value defaults to true on Android O+ and false on devices with older OS versions. Accepting the default value of false is recommended on Android N and earlier because otherwise beacon scans may be run only once every 15 minutes in the background, and no low power scans may be performed between scanning cycles. Setting this value to false will disable ScanJobs when the app is run on Android 8+, which can prohibit delivery of callbacks when the app is in the background unless the scanning process is running in a foreground service. This method may only be called if bind() has not yet been called, otherwise an `IllegalStateException` is thown. @param enabled

Configures the library to use a foreground service for bacon scanning. This allows nearly constant scanning on most Android versions to get around background limits, and displays an icon to the user to indicate that the app is doing something in the background, even on Android 8+. This will disable the user of the JobScheduler on Android 8 to do scans. Note that this method does not by itself enable constant scanning. The scan intervals will work as normal and must be configurd to specific values depending on how often you wish to scan. @see #setForegroundScanPeriod(long) @see #setForegroundBetweenScanPeriod(long) This method requires a notification to display a message to the user about why the app is scanning in the background. The notification must include an icon that will be displayed in the top bar whenever the scanning service is running. If the BeaconService is configured to run in a different process, this call will have no effect. @param notification - the notification that will be displayed when beacon scanning is active, along with the icon that shows up in the status bar. @throws IllegalStateException if called after consumers are already bound to the scanning service

Call this method from your BluetoothAdapter.LeScanCallback method. Doing so is optional, but if you do, this class will be able to count the number of distinct Bluetooth devices scanned, and prevent crashes before they happen. This works very well if the app containing this class is the only one running bluetooth LE scans on the device, or it is constantly doing scans (e.g. is in the foreground for extended periods of time.) This will not work well if the application using this class is only scanning periodically (e.g. when in the background to save battery) and another application is also scanning on the same device, because this class will only get the counts from this application. Future augmentation of this class may improve this by somehow centralizing the list of unique scanned devices. @param device
