Giulio,
Try turning on debug logging for the library with beaconManager.setDebug(true); Then run your test and capture a LogCat excerpt starting at the time you unbind from the library. Once you have that, please link to a gist of the LogCat excerpt to this thread. Please also annotate in the LogCat excerpt so I know where your service calls unbind.
Thanks,
David

Thanks for fast answer.
I can try to do this, but the problem is that this behavior is completely random. Some times happens after 4 hours application is running and others after 2 or 8 hours. By the way, tomorrow I will post my service code.

Understood. Well, one way you could do it is to pipe the LogCat output to
a file, and let your app run overnight.
adb logcat > logfile.txt
Then you could search through the log, figure out where the problem
happened, and share that snippet of the log.

OK, this is my Service.
public class Collector extends Service implements BeaconConsumer, RangeNotifier {
private void collectInfo(Context context) {
collectBeaconsAroundInfo();
}
private void collectBeaconsAroundInfo() {
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter != null && mBluetoothAdapter.isEnabled()) {
BeaconManager manager = BeaconManager.getInstanceForApplication(getApplicationContext());
// This is the pattern for iBeacon. (Code redacted by David Young)
manager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("****** Code Redacted ********"));
// Bind manager
manager.bind(this);
} else {
BeAudience.getInstance().log("Collector -> Bluetooth is not enabled. Turn it on to discover beacons.");
}
}
@Override
public void onBeaconServiceConnect() {
BeAudience.getInstance().log("Collector -> Beacon service connected.");
BeaconManager manager = BeaconManager.getInstanceForApplication(getApplicationContext());
// Set range listener
manager.setRangeNotifier(this);
try {
// Start ranging
manager.startRangingBeaconsInRegion(new Region("BeAudience", null, null, null));
} catch (RemoteException e) {
e.printStackTrace();
//Unbind manager
manager.unbind(this);
}
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
BeAudience.getInstance().log("Collector -> Start new acquisition...");
collectInfo(this);
return START_NOT_STICKY;
}
@Override
public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
BeaconManager manager = BeaconManager.getInstanceForApplication(this.getApplicationContext());
BeAudience.getInstance().log("Collector -> Beacon found: #" + beacons.size());
try {
// Stop ranging
manager.stopRangingBeaconsInRegion(region);
} catch (RemoteException e) {
e.printStackTrace();
}
//Unbind manager
manager.unbind(Collector.this);
}
}
Every time my service starts, the output in logcat is always this:

in which I obtain always 0 beacons.

Problem solved.
Every time device was connected/disconnected to a cable, BeaconService restarts.
Thanks for your time.

Giulio, are you using the RegionBootstrap class? If so, this would cause the behavior you mention.

Actually no.

Looking more at this issue, it appears that the onBeaconServiceConnect() callback is not made in step 4 if the following sequence occurs:
- application binds to service (service starts)
- application unbinds from service (service stops)
- charger connected/disconnected (service starts)
- application binds to service
A solution to this is to update the BeaconManager to set the connection to the beacon service to null in step 2, and then recreate it in step 4, thereby ensuring a callback.

@Cromir, this fix has been put in the 2.1 beta releases if you would like to see if this resolves your issue.
