NullPointerException when trying to connect to web service using kSoap method Android
- by benjamin schultz
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
Here's my 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());
}
}
here's the logcat
