  <p>However, I <em>clearly</em> have an empty constructor.... ??? Here's the code it's referring to:</p>
  
  <pre><code>public class NewReminderFragment extends Fragment {
      public NewReminderFragment() {
      }
  
      @Override
      public View onCreateView(LayoutInflater inflater,
                               ViewGroup container, Bundle savedInstanceState) {
          View rootView = inflater.inflate(R.layout.new_reminder_fragment, container, false);
          ...
          return rootView;
      }
  }
  </code></pre>
  
  <p>Any one have any ideas??? This is really annoying, and not good to publish!</p>
  
  <p>I've done reasearch but to no avail.</p>
