Ksoap響應解析錯誤上的矢量

我有一個soap web服務和一個android應用程序的調用服務。應用程序始終有效，但在上次webservice更新後，出現了問題。 web服務的更新僅用於刪除一些未使用的服務。其他代碼未被修改。我的Android應用程序中使用的AsyncTask來調用服務，並取回結果：Ksoap響應解析錯誤上的矢量

public class DownloadDataTask extends AsyncTask<Void, Void, Vector<SoapObject>> { 
private static String METHOD_NAME = "getData"; 
private static String SOAP_ACTION = "http://example.com/getData"; 
private static String URL = "http://arduino-data-server.appspot.com/dataserver"; 
private static String NAMESPACE = "http://example.com/"; 

@SuppressWarnings("unchecked") 
@Override 
protected Vector<SoapObject> doInBackground(Void... arg0) { 
    try { 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

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

     androidHttpTransport.call(SOAP_ACTION, envelope); 
     Vector<SoapObject> result = (Vector<SoapObject>) envelope.getResponse(); 

     return result; 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } catch (XmlPullParserException e) { 
     e.printStackTrace(); 
    } 
    return null; 
}

，但我得到了序貫錯誤：

其中線49是我調用getResult（）方法就行了。

有什麼不對？

原因很清楚：

Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject 
cannot be cast to java.util.Vector

在這一行，你不能把結果SoapObject到矢量：

Vector<SoapObject> result = (Vector<SoapObject>) envelope.getResponse();

試試這個：

SoapObject result = (SoapObject) envelope.getResponse();
