Ksoap2 Android IllegalStateException

问题

I am using Ksoap2 to consume my webservices, on some devices i am getting this exception, java.lang.IllegalStateException: Cannot set request property after connection is made.

I am trying to resolve it from two days but without any key to resolve it.

java.lang.IllegalStateException: Cannot set request property after connection is made

And here is how i am using Ksoap,

   String soapAction = SERVICE_NAMESPACE + methodName;
    SoapObject request = new SoapObject(SERVICE_NAMESPACE, methodName);
    if (properties != null)
        for (PropertyInfo pro : properties) {
            request.addProperty(pro);
        }

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.implicitTypes = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(serviceURL, 30000);
    androidHttpTransport.debug = false;
    androidHttpTransport.call(soapAction, envelope);
return envelope.getResponse();

Any one can help with this?

Regards
