Question

Im using a few sensors – MediaRecorder and MediaPlayer, NotificationManager, a WakeLock, and LocationListener…

Here is my onResume() and onPause() functions:

void onResume() {
  super.onResume();

  //GPS Sensor
  locationListener = new MyLocationListener();
  locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
  locationManager.requestLocationUpdates(
      LocationManager.GPS_PROVIDER, 0, 0, locationListener);

  // Notification Manager
  gNotificationManager = 
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  gNotification = new Notification();
  gNotification.vibrate = gVibrate;

}

…

void onPause() {
  super.onPause();

  // Release the Recorder
  if (mRecorder != null) {
    mRecorder.release();
    mRecorder = null;
  }

  // Release the Media Player
  if(mPlayer != null) {
    mPlayer.release();
    mPlayer = null; 
  }

  // Release Power Manager
  wake.Stop();
  wake = null;

  // Release Location Listener
  locationManager.removeUpdates(locationListener); 
  locationManager = null;

}

And here’s the Logcat output…

How do I fix this error? I’ve tried to add super.onStop() to my onPause().

Answer 1

You need to make sure that you have super.onStop and super.onDestroy in your overridden methods. This could be a good candidate for the problem you have:

@Override
protected void onStop() {
    Log.w(TAG, "App stopped");

    super.onStop();
}

@Override
protected void onDestroy() {
    Log.w(TAG, "App destroyed");

    super.onDestroy();
}
