I am developing with the Pro version of the Radius Networks iBeacon SDK on a Samsung Galaxy Tab 2 running Android 4.3. The app has been successfully using the non-pro version 0.7 for a month now but I want the background events so I've gone to Pro version 1.0. The AndroidProximityLibrary project is a project dependency in Eclipse, and the ProximityKit.properties file is in src/.
The following code is my Application subclass, as described in the documentation. The app has BLUETOOTH and BLUETOOTH_ADMIN permissions. Notice from the LogCat output that the didDetermineStateForRegion() method is not called after going to sleep as expected. What has to change to get something to happen in the background?
I have seen a similar question called iBeacon background scanning PRO feature of RadiusNetworks library? but the problem there seemed to be calling IBeaconManager.unbind() which caused the OS to clean up the service. My code never calls IBeaconManager.unbind(), only IBeaconManager.bind().
public class ExampleApp extends Application implements BootstrapNotifier, IBeaconConsumer {
private static final String LOG_TAG = ExampleApp.class.getName();
private RegionBootstrap regionBootstrap;
private IBeaconManager iBeacon;
private Region region;
public ExampleApp() {
String uuid = "EBEFD083-70A2-47C8-9837-E7B5634DF520";
region = new Region("com.example.ble", uuid, null, null);
}
@Override
public void onCreate() {
super.onCreate();
iBeacon = IBeaconManager.getInstanceForApplication(this);
iBeacon.setBackgroundBetweenScanPeriod(10000);
iBeacon.setBackgroundScanPeriod(3000);
iBeacon.bind(this);
regionBootstrap = new RegionBootstrap(this, region);
}
@Override
public void onIBeaconServiceConnect() {
Log.d(LOG_TAG + ".onIBeaconServiceConnect", "connected to iBeacon service");
try {
iBeacon.startRangingBeaconsInRegion(region);
} catch (RemoteException e) {
String msg = "caught exception while enabling beacon ranging";
Log.e(LOG_TAG + ".onIBeaconServiceConnect", msg, e);
}
}
@Override
public void didEnterRegion(Region region) {
Log.d(LOG_TAG + ".didEnterRegion", "YEAH ENTERED");
}
@Override
public void didDetermineStateForRegion(int state, Region region) {
Log.d(LOG_TAG + ".didDetermineStateForRegion", "YEAH STATE");
Intent intent = new Intent(this, LaunchActivity.class);
startActivity(intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
}
@Override
public void didExitRegion(Region region) {
Log.d(LOG_TAG + ".didExitRegion", "YEAH EXITED");
}
}
I ran the app outside beacon range, then walked into range. After 30 seconds nothing had happened so I pressed the Power button and still nothing happened. I plugged the phone in and got the trace from ADB.

The solution is to call IBeaconManager.updateScanPeriods() after setBackgroundBetweenScanPeriod() or setBackgroundScanPeriod() is called. Since my code didn't do that, the Radius SDK was still scanning at default intervals (10 minutes in the background).
