想知道android手机数据流量下IP地址

使用GPRS

首先，设置用户上网权限

其次，代码如下

public String getLocalIpAddress()

 {

 try

 {

 for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();)

 {

 NetworkInterface intf = en.nextElement();

 for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();)

 {

 InetAddress inetAddress = enumIpAddr.nextElement();

 if (!inetAddress.isLoopbackAddress())

 {

 return inetAddress.getHostAddress().toString();

 }

 }

 }

 }

 catch (SocketException ex)

 {

 Log.e("WifiPreference IpAddress", ex.toString());

 }

 return null;

 }
