Answer 1

To introduce the GenericTypeIndicator, you can change this line:

Map map = dataSnapshot.getValue(Map.class);

in to this:

GenericTypeIndicator> genericTypeIndicator = new GenericTypeIndicator>() {};
Map map = dataSnapshot.getValue(genericTypeIndicator );

This should work well in your case. Please give it a try and let me know.
