[Android\WebService] Crash applicazione inspiegabile

[wegawhite]

Grazie per i preziosi ed utili consigli.

1. ho rinominato la classe java da callws in CallWs;
2. ho fatto debug con questo codice semplificato, in cui provo a passare solo un parametro al web service, ma l'app continua ad andare in crash...

    @Override    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ws);


        SoapObject Request = new SoapObject(WSDL_TARGET_NAMESPACE,
                OPERATION_NAME);


        Request.addProperty("fname", "Peppino");


        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(Request);


        HttpTransportSE httptransport = new HttpTransportSE(SOAP_ADDRESS);


        TextView textView = new TextView(this);
        setContentView(textView);


        try {
            httptransport.call(SOAP_ACTION, envelope);
            SoapObject response = (SoapObject) envelope.getResponse();
            String val = response.getProperty(0).toString();
            Log.d("CallWs.class", "Valore restituito: " + val);
            int result = Integer.parseInt(val);
            Log.d("CallWs.class", "Valore parsato: " + result);


        } catch (SocketException ex) {
            ex.printStackTrace();
            Log.e("Error", ex.getMessage());
        } catch (Exception e) {
            e.printStackTrace();
            Log.e("Error", e.getMessage());
        }
