Running local webservice on android device connected using USB cable

I have developed an application in android using ksoap2 which used local .NET webservice and it works perfectly fine on the Emulator but when i connected the device the application starts on he device but the web service call does not work

I think i need to change the URL for the webservice.Given below is the current URL which i am using and it works on emulator but doesnt work on android device.

String NAMESPACE = "http://tempuri.org/";
String URL = "http://10.0.2.2:12736/InventoryWebService.asmx";

I google and tried many options but no help , so can anyone have any idea regarding the same then please do reply.

Who assigns the physical IP?

If over WI-FI then usually the router.

If over 3/4G cellular then you are at the mercy of the carrier.

I didn't get what you said about the physical IP, i have connected my andriod device with my pc using USB cable....

10.0.1.2 is the IP for accessing the desktop machine to which the device is connected.

Thanks for youe reply Ulf, Will surely try that, I just wanted to confirm , what will be the port number in that case or there is no need to provide port number in the URL.

The port number is whatever port you want to connect to.
