Android - Firebase Realtime Database Completion Handler

I have code which I developed which requires multiple Firebase Realtime Database lookups in order to populate a list in the View.

My issue is that the second lookup is not completing in time for the third lookup to return the required data. I am trying to use completion handlers (as i did for iOS) but its not work as desired in Android.

Skills: Android, Mobile App Development, Java, Google Firebase
