安卓----------腾讯微博客户端开发1

刚开始下载http://www.eoeandroid.com/thread-164803-1-1.html这个的代码，但是启动后很多问题，于是自己试着照代码重新写一遍，解决问题的过程中也能学习学习.

首先做的程序登录界面，这个activity里面主要是进行oauth的认证，获取accesstoken信息存储到本地，每次启动时会去读取这个数据作出判别。

因为源代码使用的是oauth1认证，而腾讯现在已经停止了，所以改成了oauth2的认证，两种方法都差不多。

需要注意的几点：

1：网络等权限要打开，否则会报错。

2：android3.0版本开始就强制不能在主线程中访问网络,要把访问网络放在独立的线程中。

以下是代码：
