title: Web service (.net ), not working as expected
body: <p>I've programmed ( actually followed a tutorial ) simple web service in android, using Ksoap libary. But it seems that it doesn't work well. Below is my simple code:</p>
  
  <pre><code>public class MainActivity extends Activity {
  
  TextView tv;
  SoapPrimitive response;
  
  final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
  final String METHOD_NAME = "CelsiusToFahrenheit";
  final String NAMESPACE = "http://www.tempuri.org/";
  final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      tv = (TextView) findViewById(R.id.tv);
      final Button button = (Button) findViewById(R.id.button1);
      button.setOnClickListener(new View.OnClickListener() {
  
          @Override 
          public void onClick(View v) {
              getValue();
  
          }
      });
  
  }
  
  private void getValue() {
  
      SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);
      soapObject.addProperty("Celsius", "33");
  
  
      SoapSerializationEnvelope serial = new SoapSerializationEnvelope(SoapEnvelope.VER11);
      serial.dotNet = true;
      serial.setOutputSoapObject(soapObject);
  
      HttpTransportSE transport = new HttpTransportSE(URL);
  
      try {
          transport.call(SOAP_ACTION, serial);
          response = (SoapPrimitive) serial.getResponse();
          tv.setText(response+"");
      } catch (IOException e) {
          e.printStackTrace();
      } catch (XmlPullParserException e) {
          e.printStackTrace();
      }
  
  }
  }
  </code></pre>
  
  <p>I only get a response "Error" in my text view. Can anyone tell me what is wrong here?</p>
