Background Service Stop when removing app from recent

I had same issue with Oppo, Vivo, Mi and etc phones,

1. after removing from recent applications app was getting killed even services was getting killed

Solution: I had add autostart permissions like this in my application and it worked.

2. After resolving this issue my app was getting frozen/killed after sometime running in background due to DOZE mode Solution: for this condition this worked and now my app is working in background in any device

3. After above things do this:

intent.setClassName("com.coloros.oppoguardelf", "com.coloros.powermanager.fuelgaue.PowerConsumptionActivity"); startActivity(intent);

call above intent, it will redirect you to battery option, "Disable Background Freeze, Abnormal Apps Optimization and Doze from \"Energy Saver ->youAPP"

Note: Once you call above intent, there you may get different options to turn off Battery saving options.

Yes, You have to return START_STICKY;

example :

public class MyService extends Service {

@Nullable

@Override
   public IBinder onBind(Intent intent) 
{
  return null;
   }

   @Override
   public int onStartCommand(Intent intent, int flags, int startId) 

{

  // Let it continue running until it is stopped.

Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
      return START_STICKY;

   }

   @Override
   public void onDestroy() {

 super.onDestroy();

Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();

 }
}
