It looks like exception is coming from your code. Service is trying to call stopRanging on beaconManager that is not initialised. Check if you are initialising BeaconManager in your BeaconService or maybe you are setting it null and then calling stopRanging Easy fix is to just check if beaconManager is not null

if (beaconManager!=null) {
  beaconManager.stopRanging(region);
}
