title: How to pass parameter to a webservice using ksoap2?
body: <p>I'm using Eclipse IDE to develop an android app. I'm trying to connect to a .net webservice.  I'm using ksoap2 version 2.3 </p>
  
  <p>When I'm calling a webmethod with no parameters, it works fine. When I come to pass a parameter to the webmethod, I get null (while debugging the webservice I discovered that) and I get a null from the webmethod in the client side code.  </p>
  
  <p>Code:</p>
  
  <pre><code>package com.examples.hello;
  import org.ksoap2.SoapEnvelope;
  import org.ksoap2.serialization.PropertyInfo;
  import org.ksoap2.serialization.SoapObject;
  import org.ksoap2.serialization.SoapSerializationEnvelope;
  import org.ksoap2.transport.HttpTransportSE;
  
  import android.app.Activity;
  import android.os.Bundle;
  import android.widget.TextView;
  public class HelloActivity extends Activity {
      /** Called when the activity is first created. */
   private static final String SOAP_ACTION = "http://Innovation/HRService/stringBs";
  
   private static final String METHOD_NAME = "stringBs";
  
   private static final String NAMESPACE = "http://Innovation/HRService/";
   private static final String URL = "http://196.205.5.170/mdl/hrservice.asmx";
   TextView tv;
  
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       tv=(TextView)findViewById(R.id.text1);
       call();
  
   }
  
   public void call()
   {
           try {
  
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            //PropertyInfo PI = new PropertyInfo();
  
               //request.addProperty("a", "myprop");
  
               SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
               envelope.setOutputSoapObject(request);
  
               envelope.dotNet=true;
               envelope.encodingStyle = SoapSerializationEnvelope.XSD;
  
  
               HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
  
               androidHttpTransport.call(SOAP_ACTION, envelope);
  
               Object result = (Object)envelope.getResponse();
  
  
               String results = result.toString();
               tv.setText( ""+results); 
           } catch (Exception e) {
               tv.setText(e.getMessage());
               }
       }
  
  
  }

  <p>Why do I get the null response, how do I pass a parameter to a webservice using ksoap2?</p>
