Question

I am sending details to be stored in a database using a web service using KSOAP. I have used visual studio to create the web service. The web service works fine. A string will be returned when the details have been inserted into the database. The problem is that this string is empty, maybe something is wrong in the way that i am getting the response. I have been trying to find out whats wrong for a long time. please help

public class Registration extends Activity{
private static final String SOAP_ACTION = "http://tempuri.org/register";
private static final String OPERATION_NAME = "register";
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://10.0.2.2:58076/WebSite1/Service.asmx";

Answer 1

Your webservice is returning a String.
Try using this to solve your problem

          Object result = envelope.getResponse();

when your webservice return values of type byte[] ,you can do this:

          SoapObject response=(SoapObject)envelope.bodyIn;

Hope it helps
