解决android上java.net.UnknownHostException: Unable to resolve host "xxxx": No address associated wit

如题：解决android上面java.net.UnknownHostException: Unable to resolve host "m.blog.csdn.net": No address associated with hostname的错误：

这是由于我们在开发的过程中没有给模拟器和Manifest开放网络导致的，

解决方法目前有两种：

1、android设备网络连接没打开,例如3G网络和WIFI网络

2、Manifest文件没有标明网络访问权限

<uses-permission android:name="android.permission.INTERNET" />
