Android Login & Registration using Web service or ASP.NET denying a passed strings with KSoap2

Question

I'm creating an Android application that will communicates between android and ASP.NET by using SOAP web service, and I'm using KSoap2 to do it. And I am making is to register an account, which takes some user information, along with a " registration code " and then i use connect web service as used to connect to web-service to ASP .

My ASP.NET IIS is working properly.

Ho to know that values are passing on web-services. That possible to send value on .net and insert on sql server on android.

Answer 1

The requests sending from android to server can be listed in server log. If you are not getting any error while sending request, it maybe recieved by the sever. Otherwise check the internet connection and make sure to add the internet permission in the manifest, also refer the ksoap lib to java build path

Answer 2

Check your WSDL file first and check your NAMESPACE = "http://tempuri.org/" is correct or not ? check your SOAP_ACTION = "http://tempuri.org/" is correct or not ? In your code,comments are available before the declaration of NAMESPACE and SOAP_ACTION please follow the comments and WSDL file for your NAMESPACE and SOAP_ACTION.

SOAP Action = URI again Namespace + Web method name
