Hi,
currently I tested Xamarin for developing portable apps.
After trying to create a splash screen according to your tutorial here (https://developer.xamarin.com/guides/android/user_interface/creating_a_splash_screen/) I received some errors like :
Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use A Toolbar instead.
after adding windowActionBar:false to the MyTheme.Splash I had another error:
AppCompat does not support the current theme.features { windowActionBar:false, windowActionBarOverlay: false, ... }
However the solution for this is to declare the parent style in MyTheme.Splash to Theme.AppCompat.NoActionBar
Best regards
