In this scenario, I cannot stop my service and which leads to crash. Anybody please help, Thanks in advance.

Answer 1

I think this way you can prevent to stop background service,
In your Service class you need to return START_STICKY in onStartCommand;

Like this,

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

If someone try to force stop service from background process, then android automatically restart your service with START_STICKY.

I hope this will help you.

Answer 2

I think implementing the onDestroy() method in your main class from where you are binding the Service can help
