I am developing a tracking application in android.
While I tested the application I found a problem:
I'm using AlarmManager to start a WakefulBroadcast that calls an IntentService, inside the OnHandleIntent method I'm calling requestLocationUpdates() from FusedLocation, and starting a Handler/CountDownTimer to removeLocationUpdates
The problem is that sometimes the service suddenly stops, without warning or explanation.
And the log stops showing the locationUpdate working or the CountDownTimer executed
Can someone help me know why my IntentService is stopping suddenly? or is there another way to keep the service executing/alive while receiving the locationUpdates?
ServiceManager:
public void StartExecuteSubscriptionService(long nextTimeMillis){
Intent intent = new Intent(contextWeakReference.get(),ExecSubscriptionWakefulBroadcast.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(contextWeakReference.get(),
Constants.EXEC_SUBSCRIPTIONS_SERVICE_REQUESTCODE,
intent, 0);
final int SDK_INT = Build.VERSION.SDK_INT;
AlarmManager am = (AlarmManager) contextWeakReference.get().getSystemService(Context.ALARM_SERVICE);
if (SDK_INT < Build.VERSION_CODES.KITKAT) {
am.set(AlarmManager.RTC_WAKEUP, nextTimeInmillis, pendingIntent);
}
else if (Build.VERSION_CODES.KITKAT <= SDK_INT && SDK_INT < Build.VERSION_CODES.M) {
am.setExact(AlarmManager.RTC_WAKEUP, nextTimeInmillis, pendingIntent);
}
else if (SDK_INT >= Build.VERSION_CODES.M) {
am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, nextTimeInmillis, pendingIntent);
}
}
WakefulBroadcast:
public class ExecSubscriptionWakefulBroadcast extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, ExecSubscriptionsService.class);
// Start the service, keeping the device awake while it is launching.
CatchExceptionsUtils.saveException(context,new Exception("Ejecutando ExecSubscriptionWakefulBroadcast "+ TelephonyUtils.getSystemDate("yyyy-MM-dd HH:mm:ss")));
startWakefulService(context, service);
}
}
ExecSuscriptionService:
@Override
protected void onHandleIntent(@Nullable Intent intent) {
CatchExceptionsUtils.saveException(this,new Exception("Ejecutando ExecSubscriptionService "+TelephonyUtils.getSystemDate("yyyy-MM-dd HH:mm:ss")));
try{
LocationUpdateRequester locationUpdateRequester = new LocationUpdateRequester(this.getApplicationContext(),intent);
locationUpdateRequester.requestLocationUpdates();
}catch (Exception e){
CatchExceptionsUtils.saveException(this,e);
}
}
LocationUpdateRequester:
public void requestLocationUpdates() throws SecurityException {
try{
googleApiClient.connect();
}catch (Exception e){
CatchExceptionsUtils.saveException(contextWeakReference.get(),e);
}
}
@Override
public void onConnected(@Nullable Bundle bundle) throws SecurityException {
try{
CatchExceptionsUtils.saveException(contextWeakReference.get(),new Exception("Conectado a GoogleServices "+TelephonyUtils.getSystemDate("yyyy-MM-dd HH:mm:ss")));
CatchExceptionsUtils.saveException(contextWeakReference.get(),new Exception("Iniciando la busqueda "+TelephonyUtils.getSystemDate("yyyy-MM-dd HH:mm:ss")));
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, TelephonyUtils.createLocationRequest(),listener);
countDownTimer = new CountDownTimer(Constants.TIMEOUT_GPS,20000) {
@Override
public void onTick(long millisUntilFinished) { CatchExceptionsUtils.saveException(contextWeakReference.get(),new Exception("Servicio "+ejecucionId+" encendido y ejecutando"));
}
@Override
public void onFinish() {
CatchExceptionsUtils.saveException(contextWeakReference.get(),new Exception("Ejecutando CountDown "+TelephonyUtils.getSystemDate("yyyy-MM-dd HH:mm:ss")));
LocationServices.FusedLocationApi.removeLocationUpdates(googleApiClient,listener);
googleApiClient.disconnect();
releaseWake();
}
}.start();
}catch (Exception e){
CatchExceptionsUtils.saveException(contextWeakReference.get(),e);
releaseWake();
}
}
Listener:
LocationListener listener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
if(location!=null){
CatchExceptionsUtils.saveException(contextWeakReference.get(),new Exception("Guardando registro; " +location.getAccuracy()+" "+location.getLatitude()+" "+location.getLongitude()+" "+TelephonyUtils.getSystemDate("yyyy/MM/dd HH:mm:ss")+" "+ejecucionId));
locationList.add(location);
}
}
};

This is not a suitable use of IntentService. Once onHandleIntent() ends, your IntentService is destroyed. Your process can be terminated at any point thereafter.
Replace the IntentService with a regular Service, kicking off your work in onStartCommand(). Call stopSelf() when you are done with the service.
