Android: Re-invoke application if task manager kill

Question

Application thread get close if its killed by task manager. Need to re-invoke application as though its killed by other application or task manager. Any idea?

Answer 1

You have to run background service with START_STICKY command. Just extends Service and override onCommand like this :

@Override
public int onStartCommand(Intent intent,int flags,int startId) {
    super.onStartCommand(intent, flags, startId);

    return START_STICKY;
}

Like this your Service is restart when it's close (by system or anything else)

You just have now check on your service (onCreate for example) if application is running or not and launch it again if not. I suppose PackageManager let you check this or simply put a static boolean is_alive to see if your activity is always running.
