Android consuming web service soap

I'm developing an application to fetch on the response server, I send the ticket number and its type. But when I send the data he does not send me a return, what can I be doing wrong?

package br.com.testes.webservicesoapxml;

import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;


import org.xmlpull.v1.XmlPullParserException;

import java.io.IOException;


public class MainActivity extends AppCompatActivity implements View.OnClickListener, Runnable {
private EditText edtSequencia;
private EditText edtTipo;
private Button buttonOk;
private TextView txtResultado;
private String chaveIntegracao = "sL8xlbkw2454kLx3i803981804000107Lxd5yV063sKc3gHx9344";
private Handler handler = new Handler();


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    edtSequencia = (EditText) findViewById(R.id.edtSequencia);
    edtTipo = (EditText) findViewById(R.id.edtTipo);
    buttonOk = (Button) findViewById(R.id.buttonOk);
    txtResultado = (TextView) findViewById(R.id.txtResultado);

    buttonOk.setOnClickListener(this);


}


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

}

@Override
public void run() {
    int sequencia = Integer.parseInt(edtSequencia.toString());
    String tipo = edtTipo.toString();

    WebService ws = new WebService();

    try {
      ws.enviaLinhaDigitavel(this.chaveIntegracao, sequencia, tipo);


        handler.post(new Runnable() {
            @Override
            public void run() {

            }
        });

    } catch (IOException e) {
        e.printStackTrace();
        Log.e("MainActivity", "Erro", e);
    } catch (XmlPullParserException e) {
        e.printStackTrace();
        Log.e("MainActivity", "Erro", e);
    }


}
}

public class WebService {


    public String enviaLinhaDigitavel(String chaveIntegracao, int sequencia, String tipo) throws IOException, XmlPullParserException {
        SoapObject soap = new SoapObject("urn:RouterBoxMobile", "EnviarLinhaDigitavel");
        soap.addProperty("ChaveIntegracao",chaveIntegracao);
        soap.addProperty("Sequencia", sequencia);
        soap.addProperty("tipo", tipo);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(soap);
        HttpTransportSE httpTransportSE = new HttpTransportSE("http://177.8.248.43:81/routerbox/ws_mobile/rbx_server_mobile.php?wsdl");


        Log.i("DEVMEDIA", "Chamando WebService para consulta de CEP");


        httpTransportSE.call("CadastrarAuteticacao",envelope);

        Object resultado = envelope.getResponse();


        return resultado.toString();
    }
}

  Esse é o serviço que estou trabalhando.
