实例化异常：没有空的构造

Question

我不断收到以下错误在我的Android应用程序，当我启动我的应用程序：

10-07 22:00:07.416 21555-21555/com.antechdevelopment.NotificationReminders E/AndroidRuntime﹕ FATAL EXCEPTION: main

但是，我清楚地有一个空的构造.... ???这是它指的代码：

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; 
    } 
} 

任何人有任何想法？这真的很烦人，不太好发表！

我已经做了研究，但无济于事。

声明片段为静态：

public static class NewReminderFragment extends Fragment
