Les référenceurs d'objets ne sont pas définis avec ksoap2

Question

Je développe une application Android avec des services de savon. Mais, cela ne fonctionne pas quand j'ai ajouté la propriété de demande. Est-ce que je manque quelque chose?

public class WebServiceCallerImp { 

private static final String METHOD_NAME = "GetForexStocksandIndexesInfo"; 
private static final String NAMESPACE = "http://tempuri.org/"; 
private static final String SOAP_ACTION = "http://tempuri.org/GetForexStocksandIndexesInfo"; 
private static final String URL = "http://mobileexam.veripark.com/mobileforeks/service.asmx"; 


public static String GetForex() { 

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    request.addProperty("IsIPAD", "true"); 
    request.addProperty("DeviceID", "test"); 
    request.addProperty("DeviceType", "ipad"); 
    request.addProperty("RequestKey", "%%UmVxdWVzdElzVmFsaWQyNzowNDoyMDE3IDEzOjEy%%"); 
    request.addProperty("Period", "Month"); 


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


    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
    androidHttpTransport.debug = true; 

    try { 
     androidHttpTransport.call(SOAP_ACTION, envelope); 
     SoapObject response = (SoapObject) envelope.getResponse(); 
     System.out.println("output: " + response.toString()); 
     return response.toString(); 
    } catch (Exception e) { 
     System.out.println("@@@@: " + e.toString()); 

    } 
    return "null"; 
}

Essayez celui-ci Je fais le même code et aucune erreur dans mon projet.

SoapSerializationEnvelope soapEnvelope = null; 
    soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    new MarshalBase64().register(soapEnvelope); 
    soapEnvelope.implicitTypes = true; 
    soapEnvelope.dotNet = true; 
    SoapPrimitive result = null; 

    soapEnvelope.setOutputSoapObject(request); 

    HttpTransportSE aht = new HttpTransportSE(SERVER_URL, Const.HTTP_TIMEOUT); 
    aht.debug = Const.LOG; 

    try { 
     Log.print("SOAP_ACTION::" + SOAP_ACTION, "SERVER_URL::" + SERVER_URL); 
     Log.print("Request", "" + aht.requestDump); 

     aht.call(SOAP_ACTION, soapEnvelope); 
     Log.print("Response", "" + aht.responseDump); 
     result = (SoapPrimitive) soapEnvelope.getResponse(); 

     Log.print("-----------Request :: ", "" + aht.requestDump); 
     Log.print("=====================FINAL RESPONSE================"); 
     Log.print("RESPONSE :: " + result); 
    } catch (UnknownHostException e) { 
     if (Const.LOG) Log.print("UnknownHostException", "" + e); 
     if (Const.LOG) Log.print("Exception in util", e.getMessage()); 
     soapEnvelope = null; 
    } catch (IOException e) { 
     if (Const.LOG) Log.print("IOException", "" + e); 
     e.printStackTrace(); 
     soapEnvelope = null; 
    } catch (XmlPullParserException e) { 
     if (Const.LOG) Log.print("XmlPullParserException", "" + e); 
     e.printStackTrace(); 
     soapEnvelope = null; 
    } catch (OutOfMemoryError e) { 
     if (Const.LOG) Log.print("OutOfMemoryError", "" + e); 
     e.printStackTrace(); 
     soapEnvelope = null; 
     result = null; 
    } catch (Exception e) { 
     if (Const.LOG) Log.print("Exception", "" + e); 
     Log.print("Utils", e); 
     e.printStackTrace(); 
     soapEnvelope = null; 
    } finally { 
     soapEnvelope = null; 
     request = null; 
     SOAP_ACTION = null; 
     SERVER_URL = null; 
     aht = null; 
    } 

La valeur de Const.LOG est vraie.
