02-08 12:36:43.490 3479-4980/? W/ActivityManager: Scheduling restart of crashed service com.wfl/.StepTrackerShakeDetectorService in 1000ms 02-08 12:36:44.494 3479-3513/? W/ActivityManager: Unable to launch app com.wfl/10139 for service Intent { cmp=com.wfl/.StepTrackerShakeDetectorService }: process is bad Here is the scenario It is basically a step tracker
StepTrackerShakeDetectorService is implemented to restart automatically when app is destroyed using START_STICKY
But when the app is removed from task list I am getting this error.
Here is the code.
public class StepTrackerShakeDetectorService extends Service { private SensorManager mSensorManager; private StepTrackerShakeDetector mShakeDetector; private Sensor step_counter_sensor; private Sensor step_detector_sensor; private Sensor step_accelerometer; @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { registerDetector(); } private void registerDetector() { mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); step_counter_sensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER); step_detector_sensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR); step_accelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); if (step_counter_sensor != null) // sensor not supported { mShakeDetector = new StepTrackerShakeDetector(Sensor.TYPE_STEP_COUNTER); mSensorManager.registerListener(mShakeDetector, step_counter_sensor, SensorManager.SENSOR_DELAY_FASTEST); } else if (step_accelerometer != null) { mShakeDetector = new StepTrackerShakeDetector(Sensor.TYPE_ACCELEROMETER); mSensorManager.registerListener(mShakeDetector, step_accelerometer, SensorManager.SENSOR_DELAY_FASTEST); } mShakeDetector.setOnShakeListener(new StepTrackerShakeDetector.OnShakeListener() { @Override public void onShake(int count) { //Code to calculate steps } }); } private void unregisterDetector() { mSensorManager.unregisterListener(mShakeDetector); } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); } @Override public int onStartCommand(Intent intent, int flags, int startId) { return START_STICKY; } @Override public void onDestroy() { unregisterDetector(); super.onDestroy(); } @Override public void onTaskRemoved(Intent rootIntent) { super.onTaskRemoved(rootIntent); Intent intent = new Intent(getApplicationContext(), StepTrackerShakeDetectorService.class); PendingIntent pendingIntent = PendingIntent.getService(this, 1, intent, PendingIntent.FLAG_ONE_SHOT); AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime() + 2000, pendingIntent); } } Here is the error in lenovo phab 2

Put this line at the end of the function in onTaskRemoved
super.onTaskRemoved(rootIntent); Answers 2
Change your onbind method which returns null to
@Override public IBinder onBind(Intent intent) { return new Binder(); } and run again if not working please see the below links
In the below link, one is using the same procedure to get alarm services and the others services in back ground check this out also
