Question 1

How to load Lottie animations from a URL in Xamarin?

Accepted Answer

For iOS, use LOTAnimationView with an NSUrl; for Android, load from a network request JSONObject using LottieComposition.Factory.FromJson. The README provides code snippets, but you'll need to handle network calls and error management separately.

Question 2

LottieXamarin vs native Xamarin animations: which should I use?

Accepted Answer

Use LottieXamarin for complex, vector-based animations from After Effects with minimal code; native Xamarin animations are better for simple, programmatic effects without design tool dependency, but require more manual implementation.

Question 3

Does LottieXamarin work with .NET MAUI?

Accepted Answer

No, LottieXamarin is specifically for Xamarin platforms; for .NET MAUI, you'll need to explore MAUI-specific bindings or alternatives, as this library isn't directly compatible.

Question 4

How to handle image assets in Lottie animations for Xamarin?

Accepted Answer

Set the image assets folder via SetImageAssetsFolder or use SetImageAssetDelegate to provide bitmaps dynamically. The README explains embedding assets in subdirectories or loading from external sources.

Question 5

What caching strategies does LottieXamarin offer and when to use them?

Accepted Answer

It provides Strong, Weak, or None caching via CacheStrategy. Use Strong or Weak for frequently reused animations, like in lists, to avoid repeated parsing and improve performance, as detailed in the Android section.

Question 6

Can I make Lottie animations interactive in Xamarin.Forms?

Accepted Answer

Yes, use event listeners such as Clicked, OnFinishedAnimation, or bind to Progress for interactive control. The README shows examples with commands and programmatic updates for responsive UIs.
