我想在我的 Mono For Android 项目中绑定 ActionBarSherlock 的 jar 库。我崇敬这份文档:http://docs.xamarin.com/android/tutorials/Binding_a_Java_Library_(.jar)
我已经成功绑定了 ActionBarSherlock 需要的 android-support-v4.jar。但是当我尝试编译 actionbarsherlock.jar 时,它给了我以下错误消息:

This method is an override of another method in the base types.
The base method expects JLO, but this method returns Cursor.
So we somehow have to fill the gap between them.
