大多数设备可以运行我的应用程序,但我收到此错误报告:

我发现有一个相关的答案: ClassNotFoundException Android

但问题是,我的异常发生在我编写的任何代码行之前,那么如何确保加载类加载器？

该项目昨天很好,但是当我今天更新Sdk工具和ADT(REV 22)时,在我运行项目时出现了"无法解析L的超类......"的错误.

我的项目使用ActionbarSherlock和SlidingMenu.

我已经尝试过了:

1. 将外部jar复制到我项目的"libs"文件夹中.(我之前已经这样做了)
2. Properties-> Java Build Path-> Projects并在那里添加库项目.
3. 清洁和重建
4. 重置计算机或IDE
5. 尝试其他包含项目lib的项目
6. 将ADT和Android sdk工具更新到最新版本22后,请遵循Class not found错误

但他们都失败了.

整个Logcat如下:

我正在使用谷歌地图api v2,一切正常.今天早上我更新了sdk,现在地图不起作用.尝试了很多东西,比如再次导入lib项目,但似乎没有任何东西可行.Plz的帮助.

这是logcat输出
