Android之获取移动网络ip

1、获取移动网络ip

2、代码

    public String getLocalIpAddress() {  
       try {  
       for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {  
       NetworkInterface intf = en.nextElement();  
               for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {  
                    InetAddress inetAddress = enumIpAddr.nextElement();  
                    if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {  
                    return inetAddress.getHostAddress().toString();  
                    }  
               }  
           }  
       } catch (SocketException ex) {  
       Log.e("get IpAddress fail", ex.toString());  
       return "";
       }  
       return "";  
   } 

加上权限

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

3、总结

记得

inetAddress instanceof Inet4Address

不要忘记，不然在Android6.0以上系统获取不到ip
