Description JeremyH 2017-01-20 22:24:29 UTC
I have latest Xamarin Studio with Beta branch set:
Xamarin Studio v6.2
Xamarin Android v7.1.0.19
SDK Tools version 25.2.5
SDK Platform tools: 25.0.3
SDK Build Tools: 25.0.2
Java SDK 1.8.0.121

Here's the sample code:

    public class MainActivity : Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

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

            Task.Factory.StartNew(() =>
            {
                Android.OS.Process.SetThreadPriority(Android.OS.ThreadPriority.Background);
                RunRequestAndroid();
            });
        }


        void RunRequestAndroid()
        {
            Authenticator.SetDefault(new Authenticator1());

            var url = new URL("https://www.google.com/");

            // Set proxy with authentication (I'm using Fiddler setup on local machine)
            var urlConnection = (HttpURLConnection)url.OpenConnection(new Proxy(Proxy.Type.Http, new InetSocketAddress("192.168.1.103", 8888)));

            try
            {
                var s = urlConnection.InputStream;
            }
            catch (Exception ex)
            {
            }
            finally
            {
                urlConnection.Disconnect();
            }
        }

        public class Authenticator1 : Authenticator
        {
            protected override PasswordAuthentication PasswordAuthentication
            {
                get
                {
                    return new PasswordAuthentication("johndoe", "1234567890".ToCharArray());
                }
            }
        }
     }



The exception is Java.IO.EOFException.


Note that if I change to non-secure URL, it works OK: 
var url = new URL("http://www.google.com/");


And in order to be sure the proxy is working, I made a .NET C# console app, which works OK with HTTPS:

        static void Main(string[] args)
        {
            try
            {
                IWebProxy proxy = new WebProxy("http://192.168.1.103:8888/");
                proxy.Credentials = new NetworkCredential("johndoe", "1234567890");
                WebRequest.DefaultWebProxy = proxy;

                var req = WebRequest.CreateHttp("https://www.google.com");
                var s = req.GetResponse();
            }
            catch (Exception ex)
            {

            }
        }

Thank you for taking the time to submit the bug. We are unable to reproduce this issue. Please attach a reproduction to the bug by starting with a clean Xamarin.Android project and adding just the code necessary to demonstrate the issue.

(There have been some changes to the TLS stack on Xamarin.Android; I suspect those changes might have fixed this issue.)
