webservice + android java上的未知错误

Question

unexpected error when i try to retrieve the data from my webservice

here is my webservice:

here is my android code, i want the result where msgFrom = 1:

private static final String SOAP_ACTION = "http://tempuri.org/selectDB";
    private static final String METHOD_NAME = "selectDB";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://localhost:2998/WebService1.asmx";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);
        AlertDialog.Builder alert = new AlertDialog.Builder(this);
        final AlertDialog.Builder alert2 = new AlertDialog.Builder(this);
        alert.setTitle("");
        alert.setMessage("Welcome Back,");

        final EditText input = new EditText(this);
        input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        input.setHint("key in password to proceed");
        alert.setView(input);

        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
          Editable value = input.getText();

          try
          {
          SoapObject Request = new SoapObject (NAMESPACE, METHOD_NAME);
          Request.addProperty("msgFrom", "1");

          SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

          soapEnvelope.dotNet = true;
          soapEnvelope.setOutputSoapObject(Request);

          AndroidHttpTransport aht = new AndroidHttpTransport(URL);

            aht.call(SOAP_ACTION, soapEnvelope);
            SoapObject resultString = (SoapObject) soapEnvelope.getResponse();          

            String addon = "";
            for(int i =0; i<resultString.getPropertyCount(); i++)
            {                            
                SoapObject array = (SoapObject) resultString .getProperty(i);
                addon = (addon + array.getProperty(0).toString());        
            }

            alert2.setMessage(addon.toString());
            alert2.show();         
          }
          catch(Exception e)
          {
              alert2.setMessage(e.getMessage());
            alert2.show();
          }
        }
        });

        alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
          public void onClick(DialogInterface dialog, int whichButton) {
            // Canceled.
              android.os.Process.killProcess(android.os.Process.myPid());
              System.exit(1);
          }
        });
    }

besides that, i also added internet permission inside my manifest

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

here is the logcat:

when i press the OK button, the apps is force close. not even throw an exception error message. what did i missed? the sample i used here is 'localhost', but i face the same error too after i uploaded the webservices to my server.

KSoap2 library is not in your APK.

If you use Eclipse, right click on your project, select "Java build Path", check ksoap2 jar is in tab "Libraries" and in tab "Order & export", Ksoap2 lib must be present and checked.
