连接安卓和 asp.net 肥皂网络服务时出错

我已经运行了我的 Web 服务，这是代码（我只是第一次尝试登录）：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Net.Http;
using System.Web.Http;
using MySql.Data.MySqlClient;
namespace WebService1
{
    /// <summary>
    /// Descripción breve de Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // Para permitir que se llame a este servicio web desde un script, usando ASP.NET AJAX, quite la marca de comentario de la línea siguiente. 
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {
        [WebMethod]
        public string ConectarBaseDatos()
        {
            try
            {
                using (MySqlCommand cm = new MySqlCommand())
                {
                    string connection = @"Server=localhost; Port=3306; Database=sistemadatosatletasfecovol; 
                                Uid=****; Pwd=*****";
                    MySqlConnection cn = new MySqlConnection(connection);
                    cm.CommandType = System.Data.CommandType.StoredProcedure;
                    cm.CommandText = "ingresarUsuario";
                    cm.Parameters.Add("_email", MySqlDbType.VarChar).Value = "asdafa@gmail.com";
                    cm.Parameters.Add("_password", MySqlDbType.VarChar).Value = "*****";
                    cn.Open();
                    cm.Connection = cn;
                    cm.ExecuteNonQuery();
                    MySqlDataReader cr = cm.ExecuteReader();       
                    cr.Read();
                    string id;
                    id = cr["mensaje"].ToString();
                    cn.Close();
                    return id;
                }
            }
            catch (Exception ex)
            {
                return ex.ToString();
            }
        }
    }
}

的工作，我实际上可以测试它并且很好，但是当我尝试将其与 andorid 连接时，我得到

Android java.net.connectexception 无法连接到

错误。

这是我的安卓代码

String NAMESPACE = "http://tempuri.org/";
String METHOD_NAME = "ConectarBaseDatos";
String SOAP_ACTION = "http://tempuri.org/ConectarBaseDatos";
String URL = "http://localhost:8080/Service1.asmx";
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(Request);

AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try
{
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
    androidHttpTransport.call(SOAP_ACTION, envelope);
    SoapObject response = (SoapObject)envelope.getResponse();
    String result =  response.getProperty(0).toString();
    editText.setText(result);
}
catch(Exception e)
{
    editText.setText(e.toString());
}

我正在使用本指南：http://seesharpgears.blogspot.in/2010/11/basic-ksoap-android-tutorial.html我正在自己的手机上测试它。
