Call SOAP service from android with ksoap error

[giozh via StackOverflow]

I have a webservice running on Google app engine, and i would to call a available service from an android device. I've follow and merge code of most tutorial about KSoap2, but i still obtain an exception on android. this is the code:

private static String METHOD_NAME = "getData";
private static String SOAP_ACTION = "http://example.com/getData";
private static String WSDL_URL = "http://arduino-data-server.appspot.com/FunctionsService.wsdl";
private static String NAMESPACE = "http://example.com/";

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER12);
envelope.setOutputSoapObject(request);

HttpTransportSE androidHttpTransport = new HttpTransportSE(WSDL_URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);

SoapObject result = (SoapObject) envelope.getResponse();
if (result != null) {
    TextView t = (TextView) this.findViewById(R.id.text_view);

    t.setText("SOAP response:\n\n"+ result.getProperty(0).toString());
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

and that's the error log:

Try it..

Try using the below code inside your mainactivityactivity below setContentView() to avoid networkOnmainThread exception..

if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }

But, doing heavy operation inside background thread using AsyncTask without blocking main thread would be great!

And also refer this link...
