Я пытаюсь получить доступ к веб-службе мыла с Android. Для этого мыльного сервиса требуется метод входа в систему. мне нужно отправить пароль и имя пользователя для получения данных. Я пишу этот код, но он не работает.

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.kxml2.kdom.Element;
import org.kxml2.kdom.Node;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class SoapTestActivity extends Activity {
     final static String NAMESPACE = "http://ws.dgpys.deloitte.com/";
     final static String METHOD_NAME = "login";
     final static String SOAP_ACTION = "http://ws.dgpys.deloitte.com/login";
     final static String URL = "http://dgpysws.teias.gov.tr/dgpys/services/EVDServis?wsdl";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        SoapObject reSoapObject = new SoapObject(NAMESPACE, METHOD_NAME);

        Element usernameTokenElement = new Element().createElement(NAMESPACE, "loginMessage");

        Element passwordElement = new Element().createElement(NAMESPACE, "Password");
        passwordElement.setAttribute(NAMESPACE, "v", "*****");
        usernameTokenElement.addChild(Node.ELEMENT, passwordElement);

        Element usernameElement = new Element().createElement(NAMESPACE, "UserName");
        usernameElement.setAttribute(NAMESPACE, "v", "*****");
        usernameTokenElement.addChild(Node.ELEMENT, usernameElement);



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

        envelope.headerOut=new Element[1];
        envelope.headerOut[0]=usernameTokenElement;

        envelope.setOutputSoapObject(reSoapObject);
        AndroidHttpTransport androidHttpTransport=new AndroidHttpTransport(URL);

        try {

            androidHttpTransport.call(SOAP_ACTION, envelope);

            SoapObject soapObject=(SoapObject) envelope.bodyIn;

            Log.e(">>>>>>>>>>>>>>>>>>", "Response: "+soapObject);


        } catch (IOException e) {
        e.printStackTrace();
        } catch (XmlPullParserException e) {
        e.printStackTrace();
        }
    }
}




 <ns1:login xmlns:ns1='http://ws.dgpys.deloitte.com'>
    <loginMessage>
    <Password v='*****' />
    <UserName v='****' />
    </loginMessage>
    </ns1:login>
