當連接到本地500內部服務器錯誤的web服務時，Android應用程序崩潰？

Question

我無法解決這個問題，從Android客戶端連接到我的web服務時出現問題。在我的MainActivity類別的管線75中的程序崩潰：

transporte.call(accionSoap, sobre); 

我認爲這個問題可能是與accionSoap東西，任何幫助將是非常apreciatted。

Web服務：

package org.webapp.ws; 

public class Hello { 
public String sayHello(String name) { 
    return "Hello !!! " + name; 
} 
} 

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.AsyncTask; 
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){ 

new ServiceCallTask().execute(); 
} 

class ServiceCallTask extends AsyncTask<String, String, String> 
{ 

@Override 
protected String doInBackground(String... params) { 
    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(); 
    } 
    return null; 
} 


}

嘗試刪除向前命名的命名空間=結束斜線「http://ws.webapp.org」
