HttpListener在发布模式下崩溃

Question

To recreate the issue 重现问题
1. Create a Android application 1.创建一个Android应用程序
2. Install Nito.AsyncEx.Context 2.安装Nito.AsyncEx.Context
3. Add the code below 3.添加以下代码
4. Set release mode 4.设置释放模式
5. Deploy code 5.部署代码
6. Start the app (and watch it burn! it crashes on both my 10.1" Marshmallow... emulator and a Samsung Galaxy Note 10.1 ) 6.启动应用程序（并观看它燃烧！它在我的10.1" Marshmallow...模拟器和Samsung Galaxy Note 10.1上都崩溃）

using Android.App;
using Android.Widget;
using Android.OS;
using System.Threading.Tasks;
using System.Net;
using System.Text;
using Nito.AsyncEx;

namespace App1
{
    [Activity(Label = "App1", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {
        private readonly HttpListener listener = new HttpListener();

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);
            var thread = new System.Threading.Thread(RunThread);
            thread.Start();
        }

        void RunThread()
        {
            AsyncContext.Run(() => Run()); //Exception in release mode
            //Task.Run(Run); //Silent exception in release mode
        }

        protected async Task Run()
        {
            listener.Prefixes.Add("http://localhost:8082/");
            listener.Start();
            while (true)
            {
                var context = await listener.GetContextAsync();
                var data = Encoding.UTF8.GetBytes("<html><body>Hello world</body></html>");
                context.Response.OutputStream.Write(data, 0, data.Length);
                context.Response.Close();
            }
        }
    }
}

I get the following exception: 我得到以下异常：

E/mono    (29964): Unhandled Exception:

Answer 1

To open a socket, your application needs the INTERNET permission. 要打开套接字，您的应用程序需要INTERNET权限。 Add the following line to your AndroidManifest.xml file: AndroidManifest.xml下行添加到您的AndroidManifest.xml文件中：

<uses-permission android:name="android.permission.INTERNET" />
