Understanding the createUser function for firebase (in particular, the Android library)

Question

So, I have the following code that I got from the firebase documentation (which I have already implemented in my application and it works fine):

    Firebase ref = new Firebase("https://myapp.firebaseio.com");
    ref.createUser("[e-mail]", "correcthorsebatterystaple", new Firebase.ValueResultHandler<Map<String, Object>>() {
       @Override
       public void onSuccess(Map<String, Object> result) {
          System.out.println("Successfully created user account with uid: " + result.get("uid"));
       }
       @Override
       public void onError(FirebaseError firebaseError) {
        // there was an error
       }
    });

after creating the user, he prints his uid on the console. However, when I enter my myapp.firebaseio.com, there is nothing there. So I have a few questions:

• Where does this new user store firebase?
• How to add some custom fields? (these functions use only email and password) ie Username

So, what I tried to do was inside onSuccess () I used ref.push () some values ​​for myapp.firebaseio.com, but then .. how can I check if the user uid created by createUser () is the same like the one i pushed? (id are different!)

                            rootRef.child("users").child(authData.getUid()).child("status").setValue("New User");
                        }

                        @Override
                        public void onAuthenticationError(FirebaseError error) {
                            // Should hopefully not happen as we just created the user.
                        }
                    }
                );

            @Override
            public void onError(FirebaseError firebaseError) {
                // Couldn't create the user, probably invalid email.
                // Show the error message and give them another chance.
            }
        }
    );
