Non sticky service starts itself and crashes

My service class code:
I am using android.app.Service



public class ServiceClass extends Service {

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(TAG, "onStartCommand: ");
// some work
stopService(intent);
return Service.START_NOT_STICKY;

}

@Nullable
@Override
public IBinder onBind(Intent intent) {
Log.i(TAG, "onBind: ");
return null;
}

@Override
public void onDestroy() {

Log.i(TAG, "onDestroy: ");
super.onDestroy();

}
}


I start it by:



startService(new Intent(MainActivity.this,ServiceClass.class));


When I run this it executes once properly. But then it tries to start again and crashes with the following error.



 ANR in com.sample.service
PID: 7381
Reason: executing service com.sample.service/.ServiceClass
Load: 0.93 / 0.73 / 0.82
CPU usage from 59831ms to 0ms ago (2018-11-15 13:26:46.668 to 2018-11-15 13:27:46.500):
13% 1810/system_server: 8.7% user + 4.5% kernel / faults: 12123 minor


stopSelf(); gives the same error. I have no pending intents no broadcast receivers, the service is registered in the manifest. the work part is a forloop counting from 1 to 100 with the current thread sleeping Thread.sleep(100);. Please don't recommend alternatives, I have a jobscheduler doing this same work and I just wanted to learn Services.

  • no, it says "executing service" which doesn't mean it started itself another time

  • just a for loop counting from 1 to 100. I delay the thread with Thread.sleep(1000). So what does "executing service" mean?

You're getting ANR since onStartCommand is on UI thread. Just use IntentService or JobIntentService (if you don't care about exact time of launch and you want to make it works on Oreo with new limitations) for this kind of jobs.

  • IntentService = HandlerThread + Service, so just use IntentService. Also IntentService make some works in onHandleIntent and will make stopself after that. Just check IntentService source it's pretty simple. Don't orget that u will have problems on Oreo devices, cuz of limitations (so there are bunch of options to avoid this limitations: 1) make startForegroundService, but user will see notification that your service is running and doing some kind of job (simplest solution), 2) JobService (JonIntentService), 3) WorkManager)
