Firebase user returns null metadata for already signed up users

Question

I have been using Firebase for authentication of users in the app. FirebaseAuth.getInstance().getCurrentUser().getMetadata() returns null when user comes back to the app after the sign up. It works perfectly when user signs up for the first time, but returns null for returning users.

Thanks for pointing this out. This is presently a bug in the persistence done by the Android SDK. We'll get on fixing this ASAP - keep an eye on upcoming release notes to know when it's resolved.

In the meantime, the workaround you can use is to write to your app's SharedPreferences to store those attributes at sign up time, and read from those Prefs when you need them elsewhere in your app. Hope this helps!
