With the simple getting started example, it works perfectly on iOS but does not show on Android. I am using Xamarin.Forms 2.5.0.121934
Hello Rikard,
I had a similar problem even before using sfBusyIndicator, with a contentview I had created to work as sfBusyIndicator.
The difference I noticed is that if you do it with a ContentPage, it works for both iOS and Android, while with a ContentView, it only works for iOS.
If you're in the same situation, you can solve as I did.
My problem was that having positioned sfBusyIndicator (as well as my contentview before) on a grid, I realized that the Frame (declared "below") that contains the rest of the objects covered the sfBusyIndicator.
So, just for Android, before doing IsBusy = True, I make invisible the main content of my contentview (for me it's a Frame) and then at IsBusy = False, I make it visible again.
So I solved and now I use sfBusyIndicator without problems (fantastic and light !).
