1. AndroidManifest.xml加入权限：

permission android:name="android.permission.ACCESS_NETWORK_STATE" />

2. android3.0以上凡是涉及到网络，下载等耗时操作，都不能在主线程中运行，不允许直接在ui线程直接操作httpClient

所以方法一：另起线程去访问。

方法二：如果不想另起线程，加上以下代码，可以取消严格限制

StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

3.获取网页内容代码：

代码一：
