Get the IPaddress of the computer in an Android project using java

Question

I am using ksoap2-android and i need to get the IP address using java so that I don't have to type it manually everytime.

What i mean by IP address is , for example if I do ipconfig using the command shell:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : f0::ed2:e3bf:8206:44%13
IPv4 Address. . . . . . . . . . . : 192.168.1.107 <--THIS ONE
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

The thing is am developing an android app, and the emulator has a different type of IP's than the machine's .
I need to get the machine's IP , how is this to be done?

thanks a lot

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 "";
    }

To get the Ipaddress of your android device you use this code.

WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ip = intToIp(ipAddress);

public String intToIp(int i) {

   return ((i >> 24 ) & 0xFF ) + "." +
               ((i >> 16 ) & 0xFF) + "." +
               ((i >> 8 ) & 0xFF) + "." +
               ( i & 0xFF) ;
}
