KSOAP нулевого указателя исключение

Question

Можно создать дубликат:
Cannot serialize issue in KSOAP in android

В моем приложении я использую службу SOAP, в том, что моя структура запроса SOAP является

<authentication> 
     <LoginID>string</LoginID> 
     <Password>string</Password> 
     </authentication> 
     <ID>int</ID> 
     <ID>int</ID> 
     <dojStr>string</dojStr> 
     <Data> 
     <Keys> 
      <POfStringString> 
      <V>string</V> 
      <K>string</K> 
      </POfStringString> 
      <POfStringString> 
      <V>string</V> 
      <K>string</K> 
      </POfStringString> 
     </Keys> 
     <CriteriaKeys> 
      <POfStringString> 
      <V>string</V> 
      <K>string</K> 
      </POfStringString> 
      <POfStringString> 
      <V>string</V> 
      <K>string</K> 
      </POfStringString> 
     </CriteriaKeys> 
     <No>int</No> 
     <Size>int</Size> 
     </Data>  
    </soap:Body> 
</soap:Envelope> 

И мой код выглядит следующим образом:

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);   
      SoapObject authentication = new SoapObject(NAMESPACE,"authentication"); 
      SoapObject pagination = new SoapObject(NAMESPACE,"pagination"); 

       authentication.addProperty(usrid); 
       authentication.addProperty(pass); 

      request.addSoapObject(authentication); 

       request.addProperty(Id); 
       request.addProperty(Id); 
       request.addProperty(dte); 

       PropertyInfo page =new PropertyInfo();  
       page.setName("V"); 
//   page.setName("K"); 
      page.setValue("10"); 
      page.setType(String.class); 
      pagination.addProperty(page); 

       request.addSoapObject(pagination); 


       request.addProperty(no); 
       request.addProperty(size);  

       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
      envelope.setOutputSoapObject(request); 
//   envelope.addMapping(NAMESPACE, "authentication", new Array().getClass()); 
      envelope.dotNet=true;   
      HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);  
      try 
      {   
       androidHttpTransport.call(SOAP_ACTION,envelope);    
//    SoapPrimitive response = (SoapPrimitive)envelope.getResponse();    
       Object result=(Object)envelope.getResponse(); ----->Getting error here. 

Ошибка я получаю:

ли я правильно настроить вход или что-то я сделал wrong.Thanks заранее.

Answer 1

Использование SoapPrimitive result = (SoapPrimitive) envelope.getResponse(); и result.toString()

Это будет работать. Если это не работает, ответьте здесь, я дам вам еще один способ.
