Dot Net Webservice Call - Android Example

In This example calling dot net webservice to get/send data to server. Using ksoap2-android-assembly-2.4-jar-with-dependencies.jar to make soap call.
Accessing a live web service ConvertWeight from http://www.webserviceX.NET/ which convert weight from one unit to another.

Download the KSOAP jar file from following link:

Steps :

   1. Add jar ksoap2-android-assembly-2.4-jar-with-dependencies.jar in your project.

   2. Creating class WebserviceCall.java and define webservice namespace and url and make soap call. Accessing a live web service ConvertWeight from http://www.webserviceX.NET/ which convert weight from one unit to another.

   3. Call WebserviceCall.java object to call getConvertedWeight method.

Project Structure :

Add jar ksoap2-android-assembly-2.4-jar-with-dependencies.jar in your project.
