Java – get the IP address of the Android device when connecting to the 3G mobile network

When I connect to WiFi, I can get the IP address of Android phone

However, when you connect to a mobile network such as 3G, can you still get the IP address of an Android phone? If so, please release the same code

Solution

Try something like this

String ipAddress = null;
    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()) {
                    ipAddress = inetAddress.getHostAddress().toString();
                }
            }
        }
    } catch (SocketException ex) {}
