Android Firebase - cant get userid using getUid() - Error: on null object reference

Question

I am using Firebase and have a signup / login activities working fine but I also want each user to update a username. It seems I am unable to run:

firebaseR         


        

Answer 1

FirebaseAuth.getInstance().getUid(); This API seems to have been removed in Firebase 12.0.0

Use this instead FirebaseAuth.getInstance().getCurrentUser().getUid();

with the appropriate null check, or use Firebase 12.0.1 where i now seems to have @Hide annotation
