Hai to All,I have a problem while calling the webservice,i have a .NET web service in the server and i am using KSOAP2(ksoap2-j2se-full-2.1.2) in android.While running the program i got an runtime Exception like "org.ksoap2.serialization.SoapPrimitive". I dont know what to do.Here is my code.

package projects.ksoap2sample;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.*;
import android.os.*;
import android.widget.TextView;

public class ksoap2sample extends Activity {
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
    private static final String METHOD_NAME = "HelloWorld";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://192.168.1.19/TestWeb/WebService.asmx";
    TextView tv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv=(TextView)findViewById(R.id.text1);

       try {

            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

            //request.addProperty("prop1", "myprop");

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet=true;
            envelope.setOutputSoapObject(request);

            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

            androidHttpTransport.call(SOAP_ACTION, envelope);

            Object result = (Object)envelope.getResponse();


           String[] results = (String[])  result;
            tv.setText( ""+results[0]); 
        } catch (Exception e) {
            tv.setText(e.getMessage());
            }
    }
}

May be my code is wrong.please help me.
