Setting DisplayName on Register for Firebase

UserProfileChangeRequest(java.lang.String, java.lang.String, boolean, boolean)’ is not public in ‘com.google.firebase.auth.UserProfileChangeRequest’. Cannot be accessed from outside package

and

Register.java:85: error: constructor UserProfileChangeRequest in class UserProfileChangeRequest cannot be applied to given types; UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest().Builder().setDisplayName(username).build(); ^ required: String,String,boolean,boolean found: no arguments reason: actual and formal argument lists differ in length

I’m getting the above error from trying to set the display name on registering a user for firebase. How do i solve this?

firebaseAuth.createUserWithEmailAndPassword(email,password).addOnSuccessListener(new O 
nSuccessListener<AuthResult>() {
                @Override
                public void onSuccess(AuthResult authResult) {
                    FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                    UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest().Builder().setDisplayName(username).build();
                    user.updateProfile(profileUpdates);
                  startActivity(new Intent(getApplicationContext(),HomeActivity.class));
                  finish();
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Toast.makeText(Register.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });

Answer

You done some mistakes:

YOUR CODE:

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest().Builder().setDisplayName(username).build();

CORRECT CODE:

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder().setDisplayName(username).build();

You have to write new UserProfileChangeRequest.Builder() instead of new UserProfileChangeRequest().Builder

Remove “()” after UserProfileChangeRequest()

Thanks.
