Firebaseui-android: Add entries to Sign Up

[dpbalcena]

Is it possible to add entries to Sign up e.g. Username, Age etc.

FirebaseUI doesn't support this because Firebase the platform doesn't support it. Firebase supports adding a name and a profile pic and that's about it. They do this because Firebase will never be able to know what every single developer wants a profile to look like.

To get around this, I think the easiest solution would be to use the realtime database. If the sign in is successful in onActivityResult, you could launch some sort of "Tell us more about you" activity or fragment. Once the user gives you all the information you need, you can use FirebaseUser#getUid() and store the profile info in the realtime database. You can also store the name and profile pic uri to make a complete User object to retrieve from the database.

To make collecting this information this easier, FirebaseUI could possibly expose some sort of api that would let devs request a list of fields to be filled out in the RegisterEmailActivity and return them in IdpResponse, but that would be a discussion to have with @samtstern.

Hope this helps!

@dpbalcena thanks for the feature request. I believe this is the same as #235. We are actively considering adding this as our next major feature but we're trying to figure out how to make it customizable while maintaining simplicity.

For now the best route, as @SUPERCILEX said, is to use the Firebase Database for this and build your own user management UI. If you have more thoughts about this, please chime in on #235.
