android开发新浪微博-OAuth认证时报错

首先上异常的截图:

 

报错的主要原因是没找到第三方的类。解决方法:项目右键Properties ------->Build Path------->Order And Export将第三方的jar包打勾。然后Clear自己的项目重新编译运行解决上述问题。详细请看截图

操作完上述步骤后Clear项目然后编译运行就OK了。

 

 

顺便把新浪OAuth认证源码给贴出来需要的哥们下载看看：

  认证需要新浪的jar包。signpost-commonshttp4-1.2.1.1.jar  signpost-core-1.2.1.1.jar下载地址：jar包下载
