Получение исключения сериализации при вызове SOAP веб-сервис

Question

я получаю ошибку serilization в

androidHttpTransport.call(SOAP_ACTION, envelope); 

Вот мой полный код для WebService класса

public class WebserviceCall extends AsyncTask<String, Void, Void> { 


    String result = ""; 

    HttpTransportSE androidHttpTransport; 

    public WebserviceCall() { 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    protected Void doInBackground(String... urls) { 

     try { 
      SOAP_ACTION = namespace + METHOD_NAME; 

      // Adding values to request object 
      request = new SoapObject(namespace, METHOD_NAME); 

      // Adding Double value to request object 
      PropertyInfo weightProp = new PropertyInfo(); 
      weightProp.setName("Weight"); 
      double w = Double.parseDouble(urls[0]); 
      weightProp.setValue(w); 
      weightProp.setType(double.class); 
      request.addProperty(weightProp); 

      // Adding String value to request object 
      request.addProperty("FromUnit", "" + urls[1]); 
      request.addProperty("ToUnit", "" + urls[2]); 

      envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

      // You can comment that line if your web service is not .NET 
      // one. 
      envelope.dotNet = true; 

      envelope.setOutputSoapObject(request); 
      HttpTransportSE androidHttpTransport = new HttpTransportSE(url); 
      androidHttpTransport.debug = true; 

      try { 

       // SOAP calling webservice 
       androidHttpTransport.call(SOAP_ACTION, envelope); 

       // Got Webservice response 
       result = envelope.getResponse().toString(); 

      } catch (Exception e) { 
       // TODO: handle exception 
       e.printStackTrace(); 
      } 
     } catch (Exception e) { 
      // TODO: handle exception 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void r) { 
     setResult(result); 
    } 
}

Answer 1

Там нет необходимости разобрать вес double.I сделал следующие изменения в свой код, и теперь он работает.

PropertyInfo weightProp =new PropertyInfo(); 
     weightProp.setName("Weight"); 
     weightProp.setValue(urls[0]); 
     weightProp.setType(double.class); 
     request.addProperty(weightProp); 

Answer 2

попробуйте это, После U сделать вызов добавить эти строки:

SoapPrimitive response = (SoapPrimitive) envelope.getResponse();  
String resString=response.toString();
