MonoDroid 简单 Web 服务器

我创建了一个在 Android 设备上运行的简单 Web 服务器，该服务器基本上以 Hello World 进行响应，该服务器在 Preview 11 之前可以正常工作。是否有任何重大更改导致该服务器不再工作，或者我做错了什么？应用程序在 context.Response.OutputStream.Write( buffer, 0, buffer.Length ); 上崩溃

代码：

public class Activity1 : Activity
{
    private HttpListener listener;

    protected override void OnCreate( Bundle bundle )
    {
        base.OnCreate( bundle );

        // Set our view from the "main" layout resource
        SetContentView( Resource.Layout.Main );

        // Get our button from the layout resource,
        // and attach an event to it
        var button = FindViewById<Button>( Resource.Id.MyButton );

        button.Click += button_Click;
    }

    private void button_Click( object sender, EventArgs e )
    {
        try
        {
            if ( !HttpListener.IsSupported )
                return;

            listener = new HttpListener();
            listener.Prefixes.Add( "http://+:8001/" );
            listener.Start();
            listener.BeginGetContext( HandleRequest, listener );
        }
        catch ( Exception )
        {
            throw;
        }
    }

    private void HandleRequest( IAsyncResult result )
    {
        HttpListenerContext context = listener.EndGetContext( result );

        string response = "<html>Hello World</html>";
        byte [] buffer = Encoding.UTF8.GetBytes( response );

        context.Response.ContentLength64 = buffer.Length;
        context.Response.OutputStream.Write( buffer, 0, buffer.Length );
        context.Response.OutputStream.Close();

        listener.BeginGetContext( HandleRequest, listener );
    }
}

日志：

I/ActivityManager（112）：进程torqsoftware.testwebserver（pid 3044）已死亡。

I/WindowManager（112）：胜利死亡：窗口{44d15120 torqsoftware.testwebserver/monodroidwebservertest.Activity1暂停= false}

D/Zygote（58）：进程3044被信号终止（4）

V/RenderScript_jni（199）：surfaceCreated

V/RenderScript_jni （199）：surfaceChanged

I/UsageStats（112）：com.android.launcher意外恢复，而已经在torqsoftware.testwebserver中恢复

W/InputManagerService（112）：收到RemoteException发送setActive（false）通知到pid 3044 uid 10062

I've created a simple web server that runs on the Android device that basically response with Hello World that used to work prior to Preview 11. Was there any major change that causes this to no longer work or am I doing something wrong? The application crashes on context.Response.OutputStream.Write( buffer, 0, buffer.Length );

Code:

public class Activity1 : Activity
{
    private HttpListener listener;

    protected override void OnCreate( Bundle bundle )
    {
        base.OnCreate( bundle );

        // Set our view from the "main" layout resource
        SetContentView( Resource.Layout.Main );

        // Get our button from the layout resource,
        // and attach an event to it
        var button = FindViewById<Button>( Resource.Id.MyButton );

        button.Click += button_Click;
    }

    private void button_Click( object sender, EventArgs e )
    {
        try
        {
            if ( !HttpListener.IsSupported )
                return;

            listener = new HttpListener();
            listener.Prefixes.Add( "http://+:8001/" );
            listener.Start();
            listener.BeginGetContext( HandleRequest, listener );
        }
        catch ( Exception )
        {
            throw;
        }
    }

    private void HandleRequest( IAsyncResult result )
    {
        HttpListenerContext context = listener.EndGetContext( result );

        string response = "<html>Hello World</html>";
        byte [] buffer = Encoding.UTF8.GetBytes( response );

        context.Response.ContentLength64 = buffer.Length;
        context.Response.OutputStream.Write( buffer, 0, buffer.Length );
        context.Response.OutputStream.Close();

        listener.BeginGetContext( HandleRequest, listener );
    }
}

log:

I/ActivityManager( 112): Process torqsoftware.testwebserver (pid 3044) has died.

I/WindowManager( 112): WIN DEATH: Window{44d15120 torqsoftware.testwebserver/monodroidwebservertest.Activity1 paused=false}
