Невозможно войти через KSOAP Android на веб-сервис

Question

Это мой примитивный веб-сервис:

@Override
    public boolean LogOn(String UserName, String Password) {

            String username = "";
            String password = "";
        if (UserName != null) {
            username = UserName;
        }
        if (Password != null) {
            password = Password;
        }
        System.out.println("username is"+username);
        System.out.println("password is"+password);
        //test parameters
        if (username.equals("admin") && password.equals("admin")) {
            return true;
        } else {
            return false;
        }

    }

Этот клиент на Android:

private static final String METHOD_NAME = "LogOn";
private static final String NAMESPACE = "http://calculator.me.org/";
private static final String URL = "http://10.0.2.2:8080/logon/WebServiceImplService?wsdl";


@Override
    protected Integer doInBackground(String... params) {
        // TODO Auto-generated method stub
         try 
          {
             SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
             //Add the input variables for the method 
             request.addProperty("username", "admin");
             request.addProperty("password","admin");
             SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
             envelope.setOutputSoapObject(request);
             System.setProperty("http.keepAlive", "false");
             HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
             androidHttpTransport.debug=true;
             androidHttpTransport.call(getSoapAction(METHOD_NAME), envelope);
             SoapObject result = (SoapObject) envelope.bodyIn;
             //get response from web server
             String d =result.getProperty("return").toString();
            // Logging the raw request and response (for debugging purposes)
             Log.d(TAG, "HTTP REQUEST:\n" + androidHttpTransport.requestDump);
             Log.d(TAG, "HTTP RESPONSE:\n" + androidHttpTransport.responseDump);
             Log.i(TAG,"response from service:"+d);
             if(d.equals("true"))
             {
                 //The result will be here, use it wisely :)
                 return 1;
             }

             else
                 return 0;
          } catch (Exception e) {
              Log.e(TAG,"doInBackground failed"+e);
              e.printStackTrace();
              return 0;

          }

    }

Когда я провожу тестирование веб-сервиса, зайдите на веб-сервис:

INFO:   username isadmin
INFO:   password isadmin

Когда я пытаюсь войти в систему из Android-клиента, я получаю следующий журнал:

INFO:   username is
INFO:   password is

Если я удаляю проверку нулевого указателя, на веб-сервисе я получаю исключение NullPointerException. Логи из Android-клиента:

В чем дело?

У меня похожая проблема. Я решил прочитать:

Override
    protected Integer doInBackground(String... params) {
        // TODO Auto-generated method stub
         try 
          {
             SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                 PropertyInfo pi1 = new PropertyInfo();
                 pi1.setName("arg0");
                 pi1.setValue("admin");
                 pi1.setType(String.class);
                 request.addProperty(pi1);

                 PropertyInfo pi2 = new PropertyInfo();
                 pi2.setName("arg1");
                 pi2.setValue("admin");
                 pi2.setType(String.class);
                 request.addProperty(pi2);

                 SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                 envelope.setOutputSoapObject(request);
                 System.setProperty("http.keepAlive", "false");
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
                 androidHttpTransport.debug=true;
                 androidHttpTransport.call(getSoapAction(METHOD_NAME), envelope);
                 SoapObject result = (SoapObject) envelope.bodyIn;
                 //get response from web server
                 String d =result.getProperty("return").toString();
                 // Logging the raw request and response (for debugging purposes)
                 Log.d(TAG, "HTTP REQUEST:\n" + androidHttpTransport.requestDump);
                 Log.d(TAG, "HTTP RESPONSE:\n" + androidHttpTransport.responseDump);
                 Log.i(TAG,"response from service:"+d);
                 if(d.equals("true"))
                 {
                    //The result will be here, use it wisely :)
                    return 1;
                 }

                 else
                    return 0;
                 } catch (Exception e) {
                 Log.e(TAG,"doInBackground failed"+e);
                 e.printStackTrace();
                 return 0;

              }

        }

Это поможет, только если вы привели весь метод LogOn
