Challenge: For the SignUpCallback parameter, pass in the mSignUpCallback variable initialized in this Activity.

protected void signUp(String username, String password) {
      ParseUser newUser = new ParseUser();
          newUser.setUsername(username);
      newUser.setPassword(password);
          newUser.signUpInBackground( mSignUpCallback());

What is wrong ?

The mSignUpCallback in this case is a variable, which means you don't need to include the parentheses. Parentheses are only required when you're calling a method. This is just a different way of passing in a callback.
