title: How to call a .NET Webservice from Android using KSOAP2?
body: <p>I have a problem while calling a webservice. I have a .NET web service on the server, and I am using KSOAP2 (ksoap2-j2se-full-2.1.2) in Android. While running the program I got an runtime exception like "org.ksoap2.serialization.SoapPrimitive". What should I do?</p>
  
  <p>Here is my code.</p>
  
  <pre><code>package projects.ksoap2sample;
  
  import org.ksoap2.SoapEnvelope;
  import org.ksoap2.serialization.SoapObject;
  import org.ksoap2.serialization.SoapSerializationEnvelope;
  import org.ksoap2.transport.HttpTransportSE;
  
  import android.app.*;
  import android.os.*;
  import android.widget.TextView;
  
  public class ksoap2sample extends Activity {
      /** Called when the activity is first created. */
      private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
      private static final String METHOD_NAME = "HelloWorld";
      private static final String NAMESPACE = "http://tempuri.org/";
      private static final String URL = "http://192.168.1.19/TestWeb/WebService.asmx";
      TextView tv;
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
          tv=(TextView)findViewById(R.id.text1);
  
          try {
              SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
  
              //request.addProperty("prop1", "myprop");
  
              SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
              envelope.dotNet=true;
              envelope.setOutputSoapObject(request);
  
              HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
  
              androidHttpTransport.call(SOAP_ACTION, envelope);
  
              Object result = (Object)envelope.getResponse();
  
              String[] results = (String[])  result;
              tv.setText( ""+results[0]);
          }
          catch (Exception e) {
              tv.setText(e.getMessage());
          }
      }
  }
