    The latest release artifact would be available at

    with a direct download url of

    Now you have to defines following java code in your android application:

    import org.ksoap2.SoapEnvelope;
    import org.ksoap2.serialization.SoapObject;
    import org.ksoap2.serialization.SoapPrimitive;
    import org.ksoap2.serialization.SoapSerializationEnvelope;
    import org.ksoap2.transport.AndroidHttpTransport;
    import android.app.Activity;
    import android.app.ProgressDialog;
    import android.os.AsyncTask;
    import android.os.Bundle;
    import android.widget.TextView;

    public class Test extends Activity {

    public class SoapTask extends AsyncTask<Void, Void, Void> {
    private final ProgressDialog dialog = new ProgressDialog(Test.this);
    protected void onPreExecute() {

    this.dialog.setMessage("Checking in...");
    this.dialog.show();

    }

    @Override
    protected Void doInBackground(Void... arg0) {
    try{
    WebServiceCallExample();
    }catch (Exception e){
    e.printStackTrace();
    }
    return null;
    }

    protected void onPostExecute(Void result) {
    TextView tv = (TextView) findViewById(R.id.Result);
    tv.setText(test_string);
    if (this.dialog.isShowing()){
    this.dialog.dismiss();
    }
    }

    }

    private String test_string;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);
    new SoapTask().execute();
    }

    @SuppressWarnings("deprecation")
    public void WebServiceCallExample() {
    final String NAMESPACE = "http://tempuri.org/";
    final String URL = "http://yoururl.com/testService.svc";
    final String METHOD_NAME = "SayHello";
    final String SOAP_ACTION = "http://tempuri.org/IWFPService/SayHello";

    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

    /* Set the web service envelope */
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(Request);
    System.out.println("Request::" + Request.toString());

    AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
    try{
    androidHttpTransport.call(SOAP_ACTION, envelope);
    //SoapObject response = (SoapObject) envelope.getResponse();
    SoapPrimitive sp = (SoapPrimitive) envelope.getResponse();

    SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
    System.out.println("Response::" + resultsRequestSOAP.toString());
    test_string = sp.toString();
    }catch (Exception e){
    e.printStackTrace();
    }
    }
    }


    test.xml layout file here:

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:orientation="vertical" >


        <TextView
            android:id="@+id/Result"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="7dip"
            android:layout_marginRight="7dip"
            android:gravity="fill_vertical|fill_horizontal"
            android:layout_gravity="center_horizontal"
             android:textSize="24dip" android:text="test"
            android:textStyle="bold" >
