I have a problem navigating within the application. When I use both the hardware and action bar buttons to return to my MainPage after a few times I can no longer navigate, sometimes the screen even freezes, I searched a lot and read somewhere that could be something in the background of the main page, the my case the page as a CustomRenderer, but it should not be a problem, because it still navigates a few times, I tried removing the Gradient from the background leaving white (default), until navigated a little more but continues to freeze the app or just not browsing anymore .
It is worth registering that inserting a breakpoint in the command that makes the navigation, in 100% of the times it still passes in the line to navigate, I do not know what can be happening.
Used Framework: PRISM
App.xaml.cs:
protected override async void OnInitialized()
{
InitializeComponent();
await NavigationService.NavigateAsync("NavigationPage/" + nameof(DashboardPage));
}
Gradient Renderer example:
public class GradientPageRenderer : PageRenderer
{
protected override void OnElementChanged(VisualElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.OldElement == null) // perform initial setup
{
var page = e.NewElement as ContentPage;
var gradientLayer = new CAGradientLayer();
gradientLayer.Frame = View.Bounds;
gradientLayer.Colors = new CGColor[]
{
((Color)App.Current.Resources["DefaultGreenColor"]).ToCGColor(),
((Color)App.Current.Resources["DefaultPurpleColor"]).ToCGColor()
};
View.Layer.InsertSublayer(gradientLayer, 0);
}
}
}
The problem occurs on iOS and Android.
