I made a custom renderer for LottieUWP
[assembly: ExportRenderer(typeof(LottieView), typeof(LottieViewRenderer))]
namespace Gorilla.Forms.UWP.Source.Renderer.Lottie
{
public class LottieViewRenderer : ViewRenderer<LottieView, LottieAnimationView>
{
private LottieAnimationView AnimationView;
protected override void OnElementChanged(ElementChangedEventArgs<LottieView> e)
{
base.OnElementChanged(e);
if (Control == null)
{
if (e.NewElement == null) return;
AnimationView = new LottieAnimationView()
{
Name = e.NewElement.AnimationPath,
FileName = e.NewElement.AnimationPath,
AutoPlay = true,
RepeatCount = -1
};
SetNativeControl(AnimationView);
}
}
}
}
This works, but sometimes when hovering or waiting some seconds, I get an error:
WinRT information: Attempting to close a CanvasActiveLayer that is not top of the stack. The most recently created layer must be closed first.
at System.Runtime.InteropServices.WindowsRuntime.IClosable.Close()
at System.Runtime.InteropServices.WindowsRuntime.IClosableToIDisposableAdapter.Dispose()
at LottieUWP.LottieDrawable.Draw(CanvasDevice device, BitmapCanvas bitmapCanvas, CompositionLayer compositionLayer, Rect bounds, Single scale, Byte alpha, Matrix3X3 matrix, Double width, Double height, CanvasDrawingSession canvasDrawingSession)
at LottieUWP.LottieDrawable.CanvasControlOnDraw(ICanvasAnimatedControl canvasControl, CanvasAnimatedDrawEventArgs args)
at Windows.ApplicationModel.Core.UnhandledError.Propagate()
at Microsoft.AppCenter.Utils.ApplicationLifecycleHelper.<.ctor>b__17_1(Object sender, UnhandledErrorDetectedEventArgs eventArgs)
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
at Microsoft.AppCenter.Utils.ApplicationLifecycleHelper.<.ctor>b__17_1(Object sender, UnhandledErrorDetectedEventArgs eventArgs)
This seems to be a bug inside LottieUWP or is my implementation incorrect?

It might help to see your LottieView and the AnimationPath. I assume this is a json string? IOW, can you supply a MCVE (minimal, complete, verifiable example? stackoverflow.com/help/mcve

From the error info,CanvasActiveLayeris not top of the stack, and it will be released, then it cause thecanvasControlparameter empty withinCanvasControlOnDrawmethod. So, you need checkLottieViewclass and how you use it.

It might help to see your LottieView and the AnimationPath. I assume this is a json string? IOW, can you supply a MCVE (minimal, complete, verifiable example? stackoverflow.com/help/mcve

From the error info,CanvasActiveLayeris not top of the stack, and it will be released, then it cause thecanvasControlparameter empty withinCanvasControlOnDrawmethod. So, you need checkLottieViewclass and how you use it.
