title: NullPointerException when trying to connect to web service using kSoap method Android
body: <p>My web service should be returning an integer, but every time i run the code i get the NullPointerException error.
  Any ideas or help would be very appreciated</p>
  
  <p>Here's my code:</p>
  
  <pre><code>public class CGCountTest extends Activity {
  
      TextView testTV;
  
      private static final String NAMESPACE = "http://passport-america.com/webservices/";
      private static final String URL = "http://localhost:11746/Service1.asmx";
      private static final String SOAP_ACTION = "http://www.passport-america.com/webservices/getCGCount";
      private static final String METHOD_NAME = "getCGCount";
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.soap_test);
  
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
              SoapSerializationEnvelope envelope =
                  new SoapSerializationEnvelope(SoapEnvelope.VER11);
                  envelope.dotNet = true;
                  envelope.setOutputSoapObject(request);
                  HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
  
                  try {
                      androidHttpTransport.call(SOAP_ACTION, envelope);
                      java.lang.Integer result = (Integer)envelope.getResponse();
                      TextView testTV = (TextView)findViewById(R.id.testTV);
                      result.toString();
                      testTV.setText(result);
                  }
                  catch(Exception e)
                  {
                      testTV.setText(e.getMessage());
                  }
      }
