Andriod mSignUpCallback

Having problems with challenge 2 of 3 in adding users to parse code challenge...

./SignUpActivity.java:25: reached end of file while parsing
};
  ^
./SignUpActivity.java:24: cannot find symbol
symbol  : constructor SignUpCallback(com.parse.SignUpCallback)
location: class com.parse.SignUpCallback
      newUser.signUpInBackground(new SignUpCallback(mSignUpCallback){});```
                                 ^
And my code is as follows


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



any ideas?

The code should be:

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

Hopes it helped you! ^_^

Another confusing forum thread/answer...

Maybe this would help:

import android.app.Activity;
import android.util.Log;
import com.parse.ParseUser;
import com.parse.ParseException;
import com.parse.SignUpCallback;

public class SignUpActivity extends Activity {

    public static final String TAG = SignUpActivity.class.getSimpleName();

    protected SignUpCallback mSignUpCallback = new SignUpCallback() {
        @Override
        public void done(ParseException e) {

        }
    };

    // onCreate() and other code has been omitted

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

The challenge was:

Challenge Task 2 of 3

Now let's use the signUpInBackground() method to sign up this new user. For the SignUpCallback parameter, pass in the mSignUpCallback variable initialized in this Activity.

Maybe because of that semi colon; (mSignUpCallback){}); <------

The signup callback is already initialized as a member variable. No need to create a new one. Try this:

newUser.signUpInBackground(mSignUpCallback);
