I have to display a popup. So I want to show a new page in the middle of the screen with a semi transparent background.
In the old Android apps this used to work if you just set your Page.Background to Color.Transparent and you showed the page modally with PushModalAsync. Then the previous page shone through.
However, this approach does not work anymore when you convert your app to use AppCompat. I followed this article by @JamesMontemagno to change to Material Design, but now all my pages have a white background - even if I set the BackgroundColor to Transparent.
The attached sample project demonstrates the problem. If you set AndroidTransparentPage.Droid as startup project, then the background shines through. If you set AndroidTransparentPage.Material as startup project, then it is white.
Does anybody know, how to get this working? I already have a custom page renderer on iOS for this functionality, so I'm not afraid of doing the same on Android. It should also not scroll the background page up to remove the ToolBar.
