Instantiation Exception: no empty constructor

I keep getting the following error in my Android app when I launch my app:

However, I clearly have an empty constructor.... ??? Here's the code it's referring to:

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;
    }
}

Any one have any ideas??? This is really annoying, and not good to publish!

I've done reasearch but to no avail.

Declare the Fragment as static:

public static class NewReminderFragment extends Fragment
