#5 Login and Registration Android App Tutorial Using Firebase Authentication - Display User Profile

[@user-vl8wf4xd9o]

If someone used a real-time database, replace part of the code: DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Users").child(userID); reference.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(@NonNull DataSnapshot snapshot) { User userProfile = snapshot.getValue(User.class); if(userProfile != null) { fullName.setText(userProfile.getFullName()); email.setText(userProfile.getEmail()); age.setText(userProfile.getAge()); } Previously, set the get and set methods in the 'User' class Thanks for the great tutorials! You helped me a lot.

I tried this but on an additional page called UserProfile, so once the user gets to their main activity they would click the profile button to get there and they can view/edit their user details, this isn't however working at the moment and doesn't even display the user details, any knowledge on why?

[@Ventus277]

I know this video is old, but a video on how to update these informations from the app (like an update profile button) could be really useful
