Answer 1

Just to add to Ymmanuel's answer (Thank you!) with some example code for anyone else looking for a quick copy and paste:

FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
    // User is signed in              
    String displayName = user.getDisplayName();
    Uri profileUri = user.getPhotoUrl();

    // If the above were null, iterate the provider data
    // and set with the first non null data
    for (UserInfo userInfo : user.getProviderData()) {
        if (displayName == null && userInfo.getDisplayName() != null) {
            displayName = userInfo.getDisplayName();
        }
        if (profileUri == null && userInfo.getPhotoUrl() != null) {
            profileUri = userInfo.getPhotoUrl();
        }
    }

    accountNameTextView.setText(displayName);
    emailTextView.setText(user.getEmail());
    if (profileUri != null) {
        Glide.with(this)
                .load(profileUri)
                .fitCenter()
                .into(userProfilePicture);
    }
}

The above will try to use the first display name and photo url from the providers if it wasn't initially found in the User object.

Bonus: Using glide for images: https://github.com/bumptech/glide .

I found a solution for this problem, in the Firebase documentation! The solution is to update the user profile using the: UserProfileChangeRequest:

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                      .setDisplayName(mUser.getName())
                      .setPhotoUri(Uri.parse("https://example.com/mario-h-user/profile.jpg"))
                      .build();

            firebaseUser.updateProfile(profileUpdates)
                      .addOnCompleteListener(new OnCompleteListener<Void>() {
                          @Override
                          public void onComplete(@NonNull Task<Void> task) {
                              if (task.isSuccessful()) {
                                  Log.d(TAG, "User profile updated.");
                              }
                          }
                      });

The variable mUser is already filled with the content from the fields. I used this piece of code inside the FirebaseAuth.AuthStateListener() -> onAuthStateChanged()

Answer 3

I was getting this problem when I had:

compile 'com.google.firebase:firebase-auth:10.0.0'
compile 'com.firebaseui:firebase-ui-auth:1.0.1'

A workaround that fixed it for me was to replace that with:

compile 'com.google.firebase:firebase-auth:9.6.0'
compile 'com.firebaseui:firebase-ui-auth:0.6.0'

Iterating through user.getProviderData() as suggested elsewhere didn't fix it for the later versions.

Answer 4

Based on Alan's and Ymmanuel's answers here's the 2 helper methods that I'm using:

public static String getDisplayName(FirebaseUser user) {
    String displayName = user.getDisplayName();
    if (!TextUtils.isEmpty(displayName)) {
        return displayName;
    }

    for (UserInfo userInfo : user.getProviderData()) {
        if (!TextUtils.isEmpty(userInfo.getDisplayName())) {
            return userInfo.getDisplayName();
        }
    }

    return null;
}

public static Uri getPhotoUrl(FirebaseUser user) {
    Uri photoUrl = user.getPhotoUrl();
    if (photoUrl != null) {
        return photoUrl;
    }

    for (UserInfo userInfo : user.getProviderData()) {
        if (userInfo.getPhotoUrl() != null) {
            return userInfo.getPhotoUrl();
        }
    }

    return null;
}

Answer 5

This issue is resolved in the latest verison of firebase ui compile 'com.firebaseui:firebase-ui:1.2.0'

Answer 6

I had the same issue, I solved it by signing out the user and resigning them back in.

Call FirebaseAuth.getInstance().signOut(); to sign them out, then try again. As I've discovered, this issue is common with using email/password authentication and Social login (Facebook in my case) at the same time.
