Necesito consumir un servicio web SOAP con Android.

El problema es que antes de solicitar una función en particular, necesito autenticar un cliente utilizando la solicitud http básica.

¿Sabes cómo hacer esto usando KSOAP?

Hasta este momento he intentado usar el método sobrecargado de httpsTransportSE.call () ya que sugiere que puedo especificar encabezados adicionales para la conexión http

(ref:https: //github.com/mosabua/ksoap2-android/blob/master/ksoap2-j2se/src/main/java/org/ksoap2/transport/HttpTransportSE.jav)

headerPropertyList.add(new HeaderProperty("Authorization", "Basic : dXNlcjpwYXNz"));

"cdXNlcjpwYXNz" es una cadena codificada en base 64 de "usuario: pasar"

 public List call(String soapAction, SoapEnvelop,e envelope, List headers)
    * @param headers a list of HeaderProperties to be http header properties when establishing the connection



private static final String SOAP_ACTION = "someaddress/IPortReporting/GetPortStatus";
private static final String METHOD_NAME = "methodname";
private static final String NAMESPACE = "http://ssn.someaddress/2.0/";
private static final String URL = "new.someaddress/functionName.svc";




SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        Request.addProperty("MessageId", "1");

        SoapSerializationEnvelope soapEnvelop = new SoapSerializationEnvelope(
                11);
        //soapEnvelop.headerOut = addHeaders(); 
        soapEnvelop.dotNet = true;
        soapEnvelop.setOutputSoapObject(Request);


        List<HeaderProperty> headerPropertieList = new ArrayList<HeaderProperty>();
        headerPropertyList.add(new HeaderProperty("Authorization", "Basic : cG9ydHdzOjEyM3F3ZUFTRA=="));
        //HeaderProperty headerProperty = new HeaderProperty()

        HttpsTransportSE httpsse = new HttpsTransportSE(URL, 443, "", 5000);



        try {
            httpsse.call(SOAP_ACTION, soapEnvelop, headerPropertyList);
            //httpsse.call(SOAP_ACTION, soapEnvelop);

            SoapPrimitive resultString = (SoapPrimitive) soapEnvelop
                    .getResponse();
            tv.setText("Status: ");
        } catch (Exception e) {
            tv.setText("Some error," + " "
                    + e.getMessage());
        }

Pero tengo el mensaje "permiso denegado" informado de nuevo.
