Android - 无法安装活动ComponentInfo（com.build.ashkelon.MyActivity2）

嗯，我看到了人们给这个问题的答案。但没有任何解决我的问题。Android - 无法安装活动ComponentInfo（com.build.ashkelon.MyActivity2）

问题：当我尝试启动我的手机在我的应用我得到这个异常： java.lang.runtimeexception unable to instantiate activity componentinfo (com.build.askelon/com.build.askelon.MyActivity2) : java.lang.ClassNotFoundException : com.build.askelon.MyActivity2

那么，我试图清理和重建，不工作。我添加到主帖子堆栈跟踪。谢谢。 @CommonsWare – 2014-10-02 14:11:12

它安静简单：（Eclipse中）项目>属性> Java构建路径>库>添加外部JAR

这不是做Android的发展的正确途径。撤消你在那里做了什么，然后把JAR放到你的项目的libs/目录中。
