我有引用两个库项目一期工程。升级ADT和SDK工具后，version 17 ，应用程序，只要它击中一个参考图书馆项目之一定义的类崩溃。如错误：

I have a project that references two library projects. After upgrading the ADT and SDK tools to version 17, the app crashes as soon as it hits a reference to a class defined in one of the Library projects. Errors such as:

Unable to resolve superclass of Lcom/my/package/name/MyActivity; (118)
Link of class 'Lcom/my/package/name/MyActivity;' failed
VFY: unable to find class referenced in signature (Lcom/my/package/name/MyActivity;)

和

（我的包和类是没有这样的命名方式，只是修改他们在这里发帖）

(My package and classes are aren't named that way, just modified them for posting here)

在这里发生了什么任何想法？据我可以告诉有没有生成错误和我的项目看起来是正确引用库项目。

Any ideas on what is happening here? As far as I can tell there are no build errors and my project looks like it is referencing the library project correctly.

推荐答案

我有完全相同的问题。找到这个帖子：如何解决NoClassDefFoundError的与ADT 17 救我有些无奈。

I had the exact same problem. Finding this post: How to fix the "NoClassDefFoundError" with ADT 17 save me some frustration.
