Getting IP Address Of Android When Connected To Cellular Network

Is there any Simple Way to get the IP address Of my phone when connected to internet through mobile data Network. For getting WiFi IP address i am using following simple Technique.

Solution 1:

Use below code as i use in my app -

public static String getDeviceIPAddress(boolean useIPv4) {
    try {
        List<NetworkInterface> networkInterfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface networkInterface : networkInterfaces) {
            List<InetAddress> inetAddresses = Collections.list(networkInterface.getInetAddresses());
            for (InetAddress inetAddress : inetAddresses) {
                if (!inetAddress.isLoopbackAddress()) {
                    String sAddr = inetAddress.getHostAddress().toUpperCase();
                    boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
                    if (useIPv4) {
                        if (isIPv4)
                            return sAddr;
                    } else {
                        if (!isIPv4) {
                            // drop ip6 port suffix
                            int delim = sAddr.indexOf('%');
                            return delim < 0 ? sAddr : sAddr.substring(0, delim);
                        }
                    }
                }
            }
        }
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return "";
}

this is best and easy way.

Hope my answer is helpfull.

Should avoid using Formatter.formatIPAddress, use the following for getting the IP Address, minor differences from your code; its one function that returns wifi ip if its enabled else the cellular one that you require, you can modify it acc to need;

    public static String getLocalIpAddress() {
            WifiManager wifiMgr = (WifiManager) ApplicationController.getInstance().getSystemService(context.WIFI_SERVICE);
            if(wifiMgr.isWifiEnabled()) {
                WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
                int ip = wifiInfo.getIpAddress();
                String wifiIpAddress = String.format("%d.%d.%d.%d",
                        (ip & 0xff),
                        (ip >> 8 & 0xff),
                        (ip >> 16 & 0xff),
                        (ip >> 24 & 0xff));

                return wifiIpAddress;
            }

            for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                    InetAddress inetAddress = enumIpAddr.nextElement();
                    Log.i("","111 inetAddress.getHostAddress(): "+inetAddress.getHostAddress());
//the condition after && is missing in your snippet, checking instance of inetAddress
                    if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
                        Log.i("","111 return inetAddress.getHostAddress(): "+inetAddress.getHostAddress());
                        return inetAddress.getHostAddress();
                    }

                }
            }

        return null;
    }
