SoapObject mda = new SoapObject("","arg0");
PropertyInfo pi = new PropertyInfo();
pi.setName("mediaGuid");
pi.setValue("27499");
pi.setType(String.class);
mda.addProperty(pi);
PropertyInfo pi_hash = new PropertyInfo();
pi_hash.setName("mediaHash");
pi_hash.setValue("");
pi_hash.setType(String.class);
mda.addProperty(pi_hash);
request.addSoapObject(mda);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.addMapping(Constants.NAMESPACE, "getMediaDetails", getMediaDetails.class);
try {
HttpTransportSE httpTransportSE = new HttpTransportSE(Constants.DEFAULT_SERVER);
httpTransportSE.debug = true;
List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
headerList.add(new HeaderProperty("Authorization", "Basic "
+ org.kobjects.base64.Base64.encode("xxxxxxxx"
.getBytes())));
httpTransportSE.call(Constants.SOAP_ACTION, envelope, headerList);
SoapObject objectResult = (SoapObject) envelope.getResponse();

推荐答案
我解决了这个问题。有一个与一个的HttpConnection问题unfortunatley也不是那么容易找到它没有ksoap2源。我检查了code和发现，ksoap2使用正常的URL和HttpConnection的从Java。我建立了一个简单的例子来连接到我的网址，发现它无法连接。
I solved the problem. There was a problem with the HTTPConnection unfortunatley it is not so easy to find it without the ksoap2 sources. I checked out the code and found out that ksoap2 use the normal URL and HTTPConnection from Java. I built a simple example to connect to my URL and noticed that it was not possible to connect.
注意：首先检查简单的事情，你开始考虑到复杂的前：）
Notice: first check the simple things before you start to think to complex :)
