Getting the IP address of Android Emulator in code

Following code snippet explains the way to get the IP address of the Android Emulator.

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(LOG_TAG, ex.toString());
    }
    return null;
}

Remark

From within your app, you can simply refer to the emulator as 'localhost' or 127.0.0.1. Web traffic is routed through your development machine, so the emulator's external IP is whatever IP has been assigned to that machine by your provider. The development machine can always be reached from your device at 10.0.2.2.
