Problem with this code challenge

Inside the done() method of the callback, add an if statement to check if the ParseException e is null. If it is not null, log the message "ERROR" using the Log.e() method. Don’t forget to use TAG as the first parameter!

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(new SignUpCallback(){

        public void done(ParseException e)
        {
          if(e == null)
          {
          //success
          }
          else{
            Log.e(TAG , "ERROR");
          }
        } 
      });
    }
}

Nidhi Saini you are really close! There is only one issue that I can see here.

First, is that it's asking you to type this code in the done() callback. You went ahead and tried to create your own. Type the code in the callback that is set up for you.

Secondly, It asks you to do a check to see If it is not null. (This is just a helpful tip. Your if else should pass the challenge.) You could do something like this.

The boolean comparator != means: not equal to.

if (e!=null){
//Not null code here
//Log.e()...
}

Hope this helps. Keep coding!
