我在 .svc webservices 中工作并解析我正在使用 Ksoap2 方法，现在，当我调用该服务时，它给了我以下错误：

这是我的代码：-

private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://myserver/Manager/api/public/Login.svc";
    private final String SOAP_ACTION = "http://tempuri.org/Public/Login/ChangePassword";
    private final String METHOD_NAME = "ChangePassword";

@Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ok = (Button)findViewById(R.id.btnok);

        ok.setOnClickListener(new OnClickListener() 
        {

            public void onClick(View v) 
            {
                    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                    request.addProperty("oldPassword","123");
                    request.addProperty("newPassword","123456789");

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

                    try 
                    {
                        androidHttpTransport.call(SOAP_ACTION, envelope);
                        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
                        SoapObject obj1 = (SoapObject)envelope.bodyIn;
                        Log.v("myApp", "SoapObject Result: "+obj1.toString());
                        Log.v("myApp", "SoapPremitive Response : "+response.toString());

                       request = null;

                    } 
                    catch (Exception e) 
                    {
                        e.printStackTrace();
                        Log.d("Exception Generated", ""+e.getMessage());
                    }
            }
        });

    }

它给了我以下错误：
