Android : object is not getting passed with ksoap2

I am trying to send the custom object to soap web service using ksoap2 library with below code.

SoapObject request = new SoapObject("http://pointsystem.ws.xx.com/", "doAnalysis");
            Log.d("soapws","After rrequest");



            AnalysisRequest analysisRequest = new AnalysisRequest();
            analysisRequest.setAnalysis_Type("facebook");
            analysisRequest.setUser_Identity("kppp");
            PropertyInfo pi = new PropertyInfo();
            pi.setName("analysisRequest");
            pi.setValue(analysisRequest);
            pi.setType(AnalysisRequest.class);
            request.addProperty(pi);
            //request.addProperty("analysisRequest", analysisRequest);

            Log.d("Zumbare","After add property");
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);


            Log.d("Zumbare","After envelope");
            //envelope.dotNet=true;
            Log.d("zumbare", " request string :"+analysisRequest.toString());
            Log.d("zumbare", "request obj :"+request.toString());
            envelope.setOutputSoapObject(request);
            Log.d("Zumbare","After setOutput");
           HttpTransportSE androidHttpTransport = new HttpTransportSE("http://10.0.2.2:8080/xxPointSystemService/ServiceAPI?wsdl",300000);
           Log.d("Zumbare","After android");
            try {
                Log.d("Zumbare","In try");

                androidHttpTransport.call("http://pointsystem.ws.xx.com/doAnalysis", envelope);
                Log.d("Zumbare","After call");
            //envelope.bodyIn;
            SoapObject response = (SoapObject)envelope.getResponse();
                //AnalysisResponse response = (AnalysisResponse) envelope.getResponse();
            //SoapObject response = (SoapObject)envelope.bodyIn;
            Log.d("Zumbare","After getres");
            Log.d("Zumbare",response.toString());
            result=response.toString();

            //tv.setText(response.toString());
            } catch (Exception e) {

                Log.d("zumbare","in exception");
                Log.d("Zumbare",e.toString());
            }

But at the server side, I am getting the object values as null though the webparam annotation is set.

Below is my web service interface code:

@WebService(name = "doAnalysis", targetNamespace = "http://pointsystem.ws.xx.com/")
@SOAPBinding(style = Style.RPC)
public interface PointSystemService {

    @WebMethod
    AnalysisResponse doAnalysis(@WebParam(name = "analysisRequest")AnalysisRequest analysisRequest);

}

I am able to fire the request successfuly to the same soap web service from soap UI tool.

So can you please help me what is wrong with android code.
