title: Enable fullscreen mode in xamarin android webview
body: <p>I am trying to enable fullscreen mode in android xamarin webview. 
  I need to use player like this:
  <a href="http://organizer.inforfk.pl/GetVideoEmbedOrange?id=1589" rel="nofollow">http://organizer.inforfk.pl/GetVideoEmbedOrange?id=1589</a>
  and in iOS everything works fine but in android fullscreen button not appear in the player. </p>
  
  <p>So, I was found this solution in documentation:</p>
  
  <blockquote>
    <p>In order to support full screen &mdash; for video or other HTML content &mdash; you need to set a WebChromeClient and implement both WebChromeClient.OnShowCustomView(Android.Views.View, .ICustomViewCallback) and WebChromeClient.OnHideCustomView. If the implementation of either of these two methods is missing then the web contents will not be allowed to enter full screen. Optionally you can implement WebChromeClient.VideoLoadingProgressView to customize the View displayed whilst a video is loading.</p>
  </blockquote>
  
  <p>but i don't know it is good solution for my case and how exacly can i do this with xamarin. 
  Thx for help.</p>
