Android sending message with TLS

[NVentimiglia]

I have a hello world example using the OKHttp-ws binding library. Everything works fine when I communicate with an unsecured server. When I communicate with a ssl / tls server I receive errors when sending messages. Here is my sending code.

  public async void Send(string message)
        {
            //IWebSocket 
            if (_socket == null)
                return;

            try
            {
                message = "\"" + message + "\"";
                var buffer = new OkBuffer();
                buffer.WriteString(message, Charset.DefaultCharset());
                _socket.SendMessage(WebSocketPayloadType.Text, buffer);
                buffer.Close();
            }
            catch(Exception ex)
            {
                //
            }
        }

Here is the exception's stack trace

Resolved. I needed to wrap the call in a Task.

Task.Factory.StartNew(() =>
{
});
