HelloWorldService WCF没有响应

Question

我试图按照教程在Android中包含WCF，但我有一个系统错误，我不知道为什么。有人能帮我吗？

我已经停用了防火墙，并且已经在清单上激活了互联网。 我也尝试在IIS上直接托管WCF，但没有任何改进。我试图修改WCF上的web.config，但我无法创建该文件，因为我没有Silverlight端点。我对Android模拟器

，你会发现我的下面WCF AppConfig的代码相同的IP地址：

<sites>    
<site name="WebSite1" id="1" serverAutoStart="true"> 
    <application path="/">     
     <virtualDirectory path="/" physicalPath="%IIS_SITES_HOME%\WebSite1" /> 
    </application>    
    <bindings>     
     <binding protocol="http" bindingInformation=":8080:localhost" /> 
    </bindings>    
</site>

    </application>     
    <bindings> 
     <binding protocol="http" bindingInformation="*:32196:192.168.1.19"/> 
     <binding protocol="http" bindingInformation="*:5082:localhost"/>  
    </bindings>

    </siteDefaults>    
    <applicationDefaults applicationPool="Clr4IntegratedAppPool" /> 
    <virtualDirectoryDefaults allowSubDirConfig="true" /> 

我的Android代码如下：

public class MainActivity : Activity 
{ 
    public static readonly EndpointAddress EndPoint = new EndpointAddress("http://192.168.1.19:32196/HelloWorldService.svc"); 

    //private PrototypeAClient _client; 
    private HelloWorldServiceClient _client; 
    private Button _getHelloWorldDataButton; 
    private TextView _getHelloWorldDataTextView; 
    private Button _sayHelloWorldButton; 
    private TextView _sayHelloWorldTextView; 
    protected override void OnCreate(Bundle bundle) 
    { 
    base.OnCreate(bundle); 

    SetContentView(Resource.Layout.Main); 

    InitializeHelloWorldServiceClient(); 

    // This button will invoke the GetHelloWorldData - the method that takes a C# object as a parameter. 
    _getHelloWorldDataButton = FindViewById<Button>(Resource.Id.getHelloWorldDataButton); 
    _getHelloWorldDataButton.Click += GetHelloWorldDataButtonOnClick; 
    _getHelloWorldDataTextView = FindViewById<TextView>(Resource.Id.getHelloWorldDataTextView); 

    // This button will invoke SayHelloWorld - this method takes a simple string as a parameter. 
    _sayHelloWorldButton = FindViewById<Button>(Resource.Id.sayHelloWorldButton); 
    _sayHelloWorldButton.Click += SayHelloWorldButtonOnClick; 
    _sayHelloWorldTextView = FindViewById<TextView>(Resource.Id.sayHelloWorldTextView); 
    } 

    private void InitializeHelloWorldServiceClient() 
    { 
    BasicHttpBinding binding = CreateBasicHttp(); 

    // _client = new PrototypeAClient(binding, EndPoint); 
    _client = new HelloWorldServiceClient(binding, EndPoint); 
    _client.SayHelloToCompleted += ClientOnSayHelloToCompleted; 
    _client.GetHelloDataCompleted += ClientOnGetHelloDataCompleted; 
    } 

    private static BasicHttpBinding CreateBasicHttp() 
    { 
    BasicHttpBinding binding = new BasicHttpBinding 
    { 
     Name = "basicHttpBinding", 
     MaxBufferSize = 2147483645, 
     MaxReceivedMessageSize = 2147483645 
    }; 
    TimeSpan timeout = new TimeSpan(0, 0, 30); 
    binding.SendTimeout = timeout; 
    binding.OpenTimeout = timeout; 
    binding.ReceiveTimeout = timeout; 
    return binding; 
    } 

    private void GetHelloWorldDataButtonOnClick(object sender, EventArgs eventArgs) 
    { 
    //PrototypeAdata data = new PrototypeAdata { Name = "Mr. Chad", SayHello = true }; 
    HelloWorldData data = new HelloWorldData { Name = "Mr. Chad", SayHello = true }; 
    _getHelloWorldDataTextView.Text = "Waiting for WCF..."; 
    _client.GetHelloDataAsync(data); 
    } 

    private void SayHelloWorldButtonOnClick(object sender, EventArgs eventArgs) 
    { 
    _sayHelloWorldTextView.Text = "Waiting for WCF..."; 
    _client.SayHelloToAsync("Kilroy"); 
    } 

    private void ClientOnGetHelloDataCompleted(object sender, GetHelloDataCompletedEventArgs getHelloDataCompletedEventArgs) 
    { 
    string msg = null; 

    if (getHelloDataCompletedEventArgs.Error != null) 
    { 
     msg = getHelloDataCompletedEventArgs.Error.Message; 
    } 
    else if (getHelloDataCompletedEventArgs.Cancelled) 
    { 
     msg = "Request was cancelled."; 
    } 
    else 
    { 
     msg = getHelloDataCompletedEventArgs.Result.Name; 
    } 
    RunOnUiThread(() => _getHelloWorldDataTextView.Text = msg); 
    } 

    private void ClientOnSayHelloToCompleted(object sender, SayHelloToCompletedEventArgs sayHelloToCompletedEventArgs) 
    { 
    string msg = null; 

    if (sayHelloToCompletedEventArgs.Error != null) 
    { 
     msg = sayHelloToCompletedEventArgs.Error.Message; 
    } 
    else if (sayHelloToCompletedEventArgs.Cancelled) 
    { 
     msg = "Request was cancelled."; 
    } 
    else 
    { 
     msg = sayHelloToCompletedEventArgs.Result; 
    } 
    RunOnUiThread(() => _sayHelloWorldTextView.Text = msg); 
    } 
} 

我错过了什么？

我通过android模拟器，而不是由视觉工作室android模拟器，它的工作
