Get Mobile IP Address in Android (Code Example)

How to programmatically retrieve the device IP address in Android for both Wi-Fi and mobile data connections, with Java code examples.

Android Get Mobile IP Address Code Example

Android Get Mobile IP Address :

/**
 * Get the IP of current Wi-Fi connection
 * @return IP as string
 */
private String getIP() {
 try {
   WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
   WifiInfo wifiInfo = wifiManager.getConnectionInfo();
   int ipAddress = wifiInfo.getIpAddress();
   return String.format(Locale.getDefault(), "%d.%d.%d.%d",
   (ipAddress & 0xff), (ipAddress >> 8 & 0xff),
   (ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));
 } catch (Exception ex) {
   Log.e(TAG, ex.getMessage());
   return null;
 }
}

But what if you need to get the Mobile connection IP?

The answer is to check the NetWorkInterface like this:

/** Get IP For mobile */
public static String getMobileIP() {
  try {
    for (Enumeration<NetworkInterface> en = NetworkInterface
    .getNetworkInterfaces(); en.hasMoreElements();) {
       NetworkInterface intf = (NetworkInterface) en.nextElement();
       for (Enumeration<InetAddress> enumIpAddr = intf
          .getInetAddresses(); enumIpAddr.hasMoreElements();) {
          InetAddress inetAddress = enumIpAddr.nextElement();
          if (!inetAddress.isLoopbackAddress()) {
             String ipaddress = inetAddress .getHostAddress().toString();
             return ipaddress;
          }
       }
    }
  } catch (SocketException ex) {
     Log.e(TAG, "Exception in Get IP Address: " + ex.toString());
  }
  return null;
}

And if you want to get the IP as IPV4 just replace the line:

          if (!inetAddress.isLoopbackAddress()) {

With:

 if (!inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) {
