I am testing FirestorePagingAdapter from https://github.com/firebase/FirebaseUI-Android/tree/version-3.4.0-dev
The problem is, I'm not receiving update / change / delete events (when items do change). What can I be missing that everything works perfect, but I just don't receive the realtime events?
What you're seeing is the expected behavior.
The FirestorePagingAdapter in the FirebaseUI library is designed to get data, not to listen for realtime updates.
