  1. try to open a connection to http://www.whatismyip.com and fetch the result.
  2. Make a HTTP POST ( or GET) to your app host and check there from which IP is coming the request.
  3. use SDK.

Edit: based on comment: that is the server side role to get the client IP, not the Android job. Here is a sample how can you do it with PHP: $_SERVER['REMOTE_ADDR']

You can try the following code.

  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()) {
             String ip = Formatter.formatIpAddress(inetAddress.hashCode());
             return ip;
           }
         }
      }
    } catch (SocketException ex) {
      // 
    }
    return null;
  }

Don't forget to add the following permission in order to allow your application to open network sockets:

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

Or instead of requesting the IP from the Server, you can tell your phone to send the IP.

You can get the IP adress with the following code.

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()) {
                        return inetAddress.getHostAddress().toString();
                    }
                }
            }
        } catch (SocketException ex) {
            Log.e(tag, ex.toString());
        }
        return "";
    }
