Can ksoap2 (android) be used for calling Ebay (Finding) web services?

Question

Hi,

I am working on a android application that will use Ebay' "Finding" Webservice. I have set up all the parameters such as

NAMESPACE="http://www.ebay.com/marketplace/search/v1/services" URL="http://svcs.ebay.com/services/search/FindingService/v1" METHOD_NAME = "findItemsByKeywords" SOAP_ACTION="http://www.ebay.com/marketplace/search/v1/services/findItemsByKeywords"

Now, I add the method parameter keywords.

Question is how does ksoap2 library helpful to add SECURITY-APPNAME="Student...."? Any suggestion is appreciated. Thanks

Ann
