How to call a WCF service using ksoap2 on android?

finally I got it to workbecause the namespace missed a "/" in the end ,

following is my code

package cn.qing.ksop2test;import java.io.Writer;import org.ksoap2.*;import org.ksoap2.serialization.*;import org.ksoap2.transport.*;import org.xmlpull.v1.XmlSerializer;import android.app.Activity;import android.os.Bundle;import android.util.Xml;import android.widget.TextView;public class ksop2test extends Activity {/** Called when the activity is first created. */private static final String METHOD_NAME = "HelloWorldRequest";//  private static final String METHOD_NAME = "HelloWorld";private static final String NAMESPACE = "http://tempuri.org/";//  private static final String NAMESPACE = "http://tempuri.org";private static final String URL = "http://192.168.0.2:8080/HelloWCF/Service1.svc";//  private static final String URL = "http://192.168.0.2:8080/webservice1  /Service1.asmx";final String SOAP_ACTION = "http://tempuri.org/IService1/HelloWorld";//  final String SOAP_ACTION = "http://tempuri.org/HelloWorld";TextView tv;StringBuilder sb;private XmlSerializer writer;@Overridepublic void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    tv = new TextView(this);    sb = new StringBuilder();    call();    tv.setText(sb.toString());    setContentView(tv);}public void call() {    try {        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);        request.addProperty("Name", "Qing");        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(                SoapEnvelope.VER11);        envelope.dotNet = true;        envelope.setOutputSoapObject(request);        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);        androidHttpTransport.call(SOAP_ACTION, envelope);        SoapPrimitive result = (SoapPrimitive)envelope.getResponse();        //to get the data        String resultData = result.toString();        // 0 is the first object of data         sb.append(resultData + "\n");        } catch (Exception e) {        sb.append("Error:\n" + e.getMessage() + "\n");        }    }}

I'm using

private static final String SOAP_ACTION = "http://tempuri.org/IContact/GetContactCount";private static final String METHOD_NAME = "GetContactCount";private static final String NAMESPACE = "http://tempuri.org/";private static final String URL = "http://xxx.xxx.com/Contacts/ContactsService.Contacts.svc";

So maybe the problem is in your SOAP action.

Also is the spelling on your method name correct ie AuthenticatdUser?

In "theory" wcf with basic http binding and asmx should work the same.

It could be something to do with how your WCF service is configured.

We get a similar problem if we configure TransferMode Streamed on the client and Buffered on the server. Although not sure if this is relevant in your case.
