I'm trying to call webservice using ksoap2 I have Link http://localhost:8181/NetBeansProjects/WsDangNhap?WSDL.

Now I created a wsDangNhap on android studio, and Main Activity

public String TestLogin(String userName, String pass) throws XmlPullParserException, IOException {
    SoapObject soapObject = new SoapObject("http://webservice.service/", "TestLogin");
    soapObject.addProperty("username", userName);
    soapObject.addProperty("pass", pass);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(soapObject);
    HttpTransportSE transportSE = new HttpTransportSE("http://localhost:8181/NetBeansProjects/WsDangNhap?WSDL");

    transportSE.call("TestLogin", envelope);
    Object result  = envelope.getResponse();

    return String.valueOf(result.toString());

}

and main activity

private EditText userName;
private EditText passWords;
private Button button;
private TextView tv;
private Handler handler = new Handler();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    userName = (EditText) findViewById(R.id.userName);
    passWords = (EditText) findViewById(R.id.passWord);
    button = (Button) findViewById(R.id.button);
    tv = (TextView) findViewById(R.id.textView);
    button.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    Thread t = new Thread();
    t.start();
}


@Override
public void run() {
    String uname = userName.getText().toString();
    String pass = passWords.getText().toString();
    try {
        wsDangNhap dangNhap = new wsDangNhap();
        final String result = dangNhap.TestLogin(uname,pass);
        handler.post(new Runnable() {
            @Override
            public void run() {
                userName.setText("debug: " + result);
            }
        });

    } catch (Exception e) {
        userName.setText("catch");
    }
}

Now I can't see any resutl on userName field, and any log error.
