Description adrianknight89 2015-12-22 19:44:53 UTC
Similar to https://bugzilla.xamarin.com/show_bug.cgi?id=32635 / Galaxy S6 / Android 5.1.1

For repro, 

1) create a new solution and animate a PCL button with this method:

void AnimateButton (Button button)
     animation = new Animation ((double f) => button.Scale = f, button.Scale, 0.85, Easing.Linear, null);
     animation.Commit(button, "ScaleTo", 16, 1000, Easing.SpringIn,
	delegate(double f, bool a)
	      button.Scale = 1.0;
	() => button.IsVisible

2) Hit Android back button to go back to the home screen
3) Relaunch app to crash

If you handle OnDisappearing to abort the animation, step 3) still crashes the app if you relaunch immediately after hitting the back button. If you wait for about 5 seconds, it'll work fine.

This seems to be fixed with the latest version of XF.
