在登录该行109 =响应hhtpclient.execute（httppost）;

，其中反应是Htt的presponse的实例;我试图与这两个值

where response is an instance of HttpResponse; and i have tried with both values

httppost=new HttpPost("http://10.0.2.2/android/connection.php"); 

和

httppost=new HttpPost("http://127.0.1.1/android/connection.php"); 

（由什么是两个IP不会忽略的区别的方式吗？）

( by the way what's the difference between the two ip adresses?)

感谢，

推荐答案

互联网在你的清单文件的权限是必需的。

The permission of internet in your manifest file is required.

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

粘贴在申请后的标记清单文件。

paste this in your manifest file after application tag.
