关于java.lang.classNotFoundException:Didn‘t find class “********” Activity"on path:/data/app***.apk异常的总结

最近出现了java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{*****Activity}: java.lang.ClassNotFoundException: Didn‘t find class "*****Activity" on path: /data/app/*******.apk的错误。解决问题如下：

1.Manifest文件中注册的类名称，有没有写错，包名是否写正确。

2.有些第三方包，直接将其引入，以前是可以的，但是在最新的adt中不行。必须在程序中新建一个libs文件夹，将第三方jar文件copy到该文件夹下。

3.在java Build path面板下的order and export中，一定要把引入的jar文件勾上，否则跟没引用一样。
