You need to use a Theme.AppCompat theme (or descendant) with the design library

When I have a Floating Action Button added to a page i get this exception with Xamarin.Forms 2.5.1.527436

Java.Lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

It seems this is due to an obsolet constructor in the renderer.

This has been asked and answered already: #6

It's the consequence of the actual Android library

I'm sorry, but it hasn't, since there my Activity has a Style that does descend from an AppCompat Theme.
As saied above, the solution for me was to adjust the renderer to not use the constructor who is obsolet since Xamarin.Forms 2.5.x.
