How to restart service after the app is killed from recent tasks

Question

I have created a service to fetch current location of the device in periodic intervals. I want the service to run in the background even if the app is cleared from recently

Answer 1

If you ONLY want to restart service after it kill from Recent Task, simple use

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
}

If you use START_STICKY, when you kill app from recent task, your service will be killed (onTaskRemoved fired, onDestroy NOT fired) THEN it will auto start again (onCreate fired, onStartComand fired)
