我想在我的Mono For Android项目中绑定ActionBarSherlock的jar库.我对此文档表示敬意:http://docs.xamarin.com/android/tutorials/Binding_a_Java_Library_(.jar)

我已经成功绑定了ActionBarSherlock所需的android-support-v4.jar.但是当我尝试编译actionbarsherlock.jar时,它给出了以下错误消息:

尝试使用Xamarin Studio中的自动升级工具启动我升级到统一API的应用程序时出现异常.我可以在iPhone模拟器中看到启动画面显示大约一秒钟,然后在Main方法中抛出以下异常.
