This challenge is asking me to use the Log.e method but I am using and still marks it as an error or am i crazy?

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() {
        @Override
        public void done(ParseException e) {
          if(e==null){
          }
          else{
            Log.e(TAG, "Error");
          }
        }
      });
    }
}
