如果缺少INTERNET权限，请将此行添加到<application>标记上方的Android.manifest文件中。
<uses-permission android:name="android.permission.INTERNET/>

You don't have the INTERNET permission? 您没有INTERNET权限吗？ That, or your Wifi isn't turned on or the other IP isn't accessible (like you're trying to connect to a LAN IP via WAN). 那，或者您的Wifi没打开或者其他IP无法访问（例如您正试图通过WAN连接到LAN IP）。
