Solution 1:

As the IntentService document (https://developer.android.com/reference/android/app/IntentService) stated:

the service is started as needed, handles each Intent in turn using a worker thread, and stops itself when it runs out of work.

I think you should not put the listener in an IntentService. Instead, put it in a long running Service so that the listener can actually keep staying there to receive events.
