If you find it helpful, you can enable fullscreen on Android, just by changing the class:

`public class FormsWebViewChromeClient : WebChromeClient
{

    readonly WeakReference<FormsWebViewRenderer> Reference;

    public FormsWebViewChromeClient(FormsWebViewRenderer renderer)
    {
        Reference = new WeakReference<FormsWebViewRenderer>(renderer);
    }

    readonly FrameLayout.LayoutParams matchParentLayout = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FillParent,
                                                                                                    ViewGroup.LayoutParams.FillParent);
    private ViewGroup parent;
    View customView;

    public FormsWebViewChromeClient(ViewGroup parent)
    {
        this.parent = parent;
    }

    public override void OnShowCustomView(View view, ICustomViewCallback callback)
    {
        customView = view;
        view.LayoutParameters = matchParentLayout;
        parent.AddView(view);
        customView.Visibility = ViewStates.Visible;
    }

    public override void OnHideCustomView()
    {
        //content.Visibility = ViewStates.Visible;
        parent.RemoveView(customView);
        customView = null;
    }
}`

and change the SetupControl on the FormsWebViewRendere classe for the:

webView.SetWebChromeClient(new FormsWebViewChromeClient(webView));

cheers
