How To Create Proper Soap Envelope (request Xml) In Code While Using KSoap2?

This is the soap request as obtained from SoapUi by feeding the wsdl. Copy

to

MAIN_REQUEST_URL = "http://abc.xyz.com/WSClient/WSServiceSoapHttpPort?WSDL";
NAMESPACE = "http://wsclient.xyz.com/types/";
SOAP_ACTION = "http://wsclient.xyz.com//loginservice";

and also I had to change:

String methodname = "loginservice";

to

String methodname = "loginserviceElement";

as the request/response xml has this ( typ:loginserviceElement ) tag wrapping the properties/parameters.
