I upgraded to the latest version of SfRotator and also using XF 2.3.3193 version with FormsAppCompatActivity. Below is how I implemente my rotator
SfRotator rotator = new SfRotator()
{
NavigationStripMode = NavigationStripMode.Dots,
NavigationDelay = 2000,
NavigationDirection = NavigationDirection.Horizontal,
NavigationStripPosition = NavigationStripPosition.Bottom,
EnableAutoPlay = true,
EnableLooping = true,
EnableSwiping = true,
Margin = new Thickness(30, 10),
VerticalOptions = LayoutOptions.Start,
HorizontalOptions = LayoutOptions.Center,
HeightRequest = Device.Idiom == TargetIdiom.Phone ? 300 : 500,
WidthRequest = Device.Idiom == TargetIdiom.Phone ? 300 : 500
};
If I click soft/hard back button and navigate to page before, I am getting exception below. It looks like something to do with the SfRotator.get_SelectedIndex and Rotator.SfRotator+ISelectionChangedListenerImplementor.SelectionChanged , I tried to handle SelectionChanged event in my code behind but it didnt help.
I tried this enabling and disabling linker as I use linker. I also use Proguard included in my application
