Answer 1

In the Realtime Database, if you need to remove the listener, you have to call Query#removeEventListener(@NonNull ValueEventListener listener) which:

Removes the specified listener from this location.

Besides that, if it's about Android, don't forget to remove the listener accordingly to the life-cycle of your activity.
