how to keep my background service active when android system kills my app?

Question

I have a background service which runs in background to track screen on and off events. its started as below :

Intent intentService = new Intent(context, UnlockdService.class);
context.startService(intentService);

And it is returning Service.START_REDELIVER_INTENT in the method onStartCommand. But still when android system kills app this thread dies as well.

How can I prevent it?

There is no way you can assure that a service won't be killed. The best you can do is make sure you're restarted when possible. — Gabe Sechan, Mar 04 '16 at 00:28

I think it's a better solution to have a BroadcastReceiver instead of a Service. In your onReceive, you could then start your service to do its work, and then the service could self terminate - maybe you could use an IntentService if your work is one shot.

If you still want a Service, you can make it less likely to be killed by having a permanent notification in the notification bar, but that can be bad from a user perspective. I strongly recommend going the broadcast receiver route.

Such a stupid issue.. solution was so simple... START_STICKY did the job :D — Kruti Mevada, Mar 04 '16 at 02:45

The solution was so simple: Returning START_STICKY from onStartCommand() did the job.
