连接到webservice LOCAL时，Android应用程序崩溃

从Android客户端连接到我的web服务时遇到问题。在我的MainActivity类中，程序在第66行崩溃：

transporte.call(accionSoap, sobre);

我认为问题可能与accionSoap有关，任何帮助都会非常令人沮丧。

MainActivity：

package com.example.ejemplosoap;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

//Napespace definido en el servicio web
private final String namespace = "http://ws.webapp.org/";
//Fichero de definicion del servicio web
private final String url = "http://10.0.2.2:8080/WebServiceServer/services/Hello";
//namespace + metodo
private final String accionSoap = "http://ws.webapp.org/sayHello";
//Metodo que queremos ejecutar en el servicio web
private final String Metodo = "sayHello";

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void onClickLogin(View view){
    try {

        System.out.println("1");
        // Modelo el request
        SoapObject request = new SoapObject(namespace, Metodo);
        //request.addProperty("name", "Juan!"); // Paso parametros al WS
        PropertyInfo primerParametro = new PropertyInfo ();
        System.out.println("2");
        primerParametro.setName("name");
        primerParametro.setValue("Juan");
        request.addProperty(primerParametro);
        System.out.println("3");
        // Modelo el Sobre
        SoapSerializationEnvelope sobre = new         SoapSerializationEnvelope(SoapEnvelope.VER11);
        //si esta hecho o no en puntoNet
        sobre.dotNet = false;
        sobre.setOutputSoapObject(request);
        System.out.println("4");

        // Modelo el transporte
        HttpTransportSE transporte = new HttpTransportSE(url);
        System.out.println("5");

        // Llamada
        transporte.call(accionSoap, sobre);
        System.out.println("6");

        // Resultado
       // SoapPrimitive resultado = (SoapPrimitive) sobre.getResponse();
        String cadenaDevuelta =(String) sobre.getResponse();
        Log.i("Resultado", cadenaDevuelta);


    } catch (Exception e) {
        Log.e("MainActivity", "ERROR");
                e.printStackTrace();

    }

}



}

android.os.NetworkOnMainThreadException

您正在主线程中运行不允许的网络操作，在另一个线程中执行操作。

使用AsyncTask并使用doInBackground方法进行通话，或创建new Thread()并使用run方法进行通话。

您需要使用asynctask来处理Web服务调用，
