Good day. Such a problem was written by the service, which in the background collects coordinates with GPS. The problem is what when gps is enabled on the phone, the application works and collects the coordinates even if the application backs up to kill the application, but as soon as the gps on the device is turned off, the service also dies and when the gps is turned back on, the service does not start (PS , suddenly the service did not die, but went to bed). Broadcast receiver below
public class GPSReciever extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // TODO: This method is called when the BroadcastReceiver is receiving // an Intent broadcast. Log.wtf("backservice","in RECIEVER"); context.startService(new Intent(context,GPSService.class)); } } Service Code that catches gps in the background
