Firebase UserProfileChangeRequest isn't working

问题

I'm trying to create an profile activity, where users can change those Profile picture and Display name, I'm trying to update user photo or user name, CompleteListener called, task.isSuccessful = true but nathing done, why?

Function to update name:

FirebaseUser mFirebaseUser = FirebaseAuth.getInstance().getCurrentUser();
final String newName;
newName = input.getText().toString();
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(newName)
.build();
mFirebaseUser.updateProfile(profileUpdates)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
DatabaseReference mFirebaseDatabaseReference = FirebaseDatabase.getInstance().getReference().child("users");
   mFirebaseDatabaseReference.child(mFirebaseUser.getUid()).child("DisplayName").setValue(newName);
updateUI();
Toast.makeText(ProfileActivity.this, "User display name updated.", Toast.LENGTH_SHORT).show();
} else
Toast.makeText(ProfileActivity.this, "Error while updating display name.", Toast.LENGTH_SHORT).show();
}
});

Same when i'm trying to update Profile picture that I just uploaded to Firebase Storage...

And idea?

EDIT:

Sometimes the username really get updated, I think it's take like more then 10 minutes to update, why?

回答1:

I have had a similar problem where the User information was not updating until the User re-authenticated. I resolved it by also saving this information in my firebase database. For me this made sense, as I wanted Users to be able to get basic information about other Users anyway.

My code ended up looking something like this. When the account is created, or modified, I made a call to the "users/{uid}" endpoint and updated the object there. From here I used the GreenRobot EventBus to send my new User object to whoever was subscribed so that it would be updated on the screen.

private FirebaseUser firebaseUser;

public void createUser(String email, String password, final User user, Activity activity, final View view) {
    FirebaseAuth.getInstance().createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(activity, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());

                // If sign in fails, display a messsage to the user. If sign in successful
                // the auth state listener will be notified and logic to handle
                // signed in user can be handled in the listener
                if (!task.isSuccessful()) {
                    Snackbar.make(view, task.getException().getLocalizedMessage(), Snackbar.LENGTH_SHORT).show();
                } else {
                    firebaseUser = task.getResult().getUser();

                    UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                        .setDisplayName(user.displayName)
                        .build();
                    firebaseUser.updateProfile(profileUpdates);
                    updateDatabase(user);

                    EventBus.getDefault().post(new LoginEvent());
                }
            }
        });
}

public boolean updateDatabase(User user) {
    if (firebaseUser == null) {
        Log.e(TAG, "updateDatabase:no currentUser");
        return false;
    }

    return userReference.setValue(user).isSuccessful();
}

The setup of the database watcher was done something like this. Note that you need to make sure that you remove the listener when the User logs out and add a new one when the User logs in.

protected void setupDatabaseWatcher() {
    String uid = firebaseUser.getUid();

    userReference = FirebaseDatabase.getInstance().getReference("users/" + uid);
    userReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            // This method is called once with the initial value and again
            // whenever data at this location is updated.
            User user = dataSnapshot.getValue(User.class);
            Log.d(TAG, "Value is: " + user);

            EventBus.getDefault().post(new UserUpdateEvent(user));
        }

        @Override
        public void onCancelled(DatabaseError error) {
            // Failed to read value
            Log.w(TAG, "Failed to read value.", error.toException());
        }
    });
}
