Trying to display a recyclerview in a service. The service has no problem. Its inflating the layout. The code is fine because i have an activity with the same code so the code works fine. Im just not sure whether this is the right way to show recyclerview data in a service. Can someone help me out please?
The problem is the service is showing a blank window. Like everything else is shown except the recyclerview.
Your using a new version of FirebaseUI, to start listening for data(so the data appears in the recyclerView) you need to call startListening() method.
mUsersList.setAdapter(firebaseRecyclerAdapter);
firebaseRecyclerAdapter.startListening();
Check here for more information:
