[Removed API] Removed the setScale(float) APIs from LottieAnimationView and LottieDrawable. The expected behavior was highly ambiguous when paired with other scale types and canvas transformations. For the vast majority of cases, ImageView.ScaleType should be sufficient. For remaining cases, you may apply transformations to Canvas and use LottieDrawable#draw directly.
Added support for the “Rounded Corners” effect on Shape and Rect layers (#1953)
Prior to 5.0, LottieAnimationView would always call setLayerType with either HARDWARE or SOFTWARE. In the hardware case, this would case Android to allocate a dedicated hardware buffer for the animation that had to be uploaded to the GPU separately. In the software case, LottieAnimationView would rely on View's internal drawing cache.
This has a few disadvantages:
Benefits as a result of this change:
Lottie can now render outside of its composition bounds. To allow this with views such as LottieAnimationView, set clipToCompositionBounds to false on LottieDrawable or LottieAnimationView and clipChildren to false on the parent view. For Compose, use the clipToCompositionBounds parameter.
Prior to 5.0, LottieAnimationView handled all animation controls when the view's visibility or attach state changed. This worked fine for consumers of LottieAnimationView. However, custom uses of LottieDrawable were prone to leaking infinite animators if they did not properly handle cancelling animations correctly. This opens up the possibility for unexpected behavior and increased battery drain. Lottie now behaves more like animated drawables in the platform and moves this logic into the Drawable via its setVisible API. This should lead to no explicit behavior changes if you are using LottieAnimationView. However, if you are using LottieDrawable directly and were explicitly pausing/cancelling animations on lifecycle changes, you may want to cross check your expected behavior with that of LottieDrawable after this update. This change also resolved a long standing bug when Lottie is used in RecyclerViews due to the complex way in which RecyclerView handles View lifecycles (#1495). #1981
Add an API setClipToCompositionBounds on LottieAnimationView, LottieDrawable, and the LottieAnimation composable to prevent Lottie from clipping animations to the composition bounds.
Add an API to always render dynamically set bitmaps at the original animation bounds. Previously, dynamically set bitmaps would be rendered at their own size anchored to the top left of the original bitmap. This meant that if you wanted to supply a lower resolution bitmap to save memory, it would render smaller. The default behavior remains the same but you can enable setMaintainOriginalImageBounds to be able to supply lower resolution bitmaps (#1706).
Add support for LottieProperty.TEXT to use dynamic properties for text. This enables dynamic text support for lottie-compose (#1995).
Add getters for Marker fields (#1998)
Add support for reversed polystar paths (#2003)
BREAKING CHANGES Before this release, drop shadows and blurs were completely ignored. They will now be rendered. In most cases, they will now be rendered correctly. However, you should read the implementation details here if they are not.
LottieProperty.TRANSFORM_POSITION_X and LottieProperty.TRANSFORM_POSITION_Y has been added to enable dynamic properties on transform positions that have split dimensions enabled (#1714)KeyPath (#1710)ColorStateLists in LottieAnimationView lottie_colorFilter xml attribute (#1708)LottieDrawable bounds internally. It will not respect the bounds set on it (#1713)LottieAnimationView with another drawable then setting it back would cause the animation to not render (#1703)Added a new global configuration to add a custom network stack, custom network cache, enable systrace markers, and more (#1629)
Lottie.initialize and LottieConfig.Builder.Add support for parsing dotLottie files (#1660)

LottieCompositionFactory.clearCache().setFailureListener and resetFailureListener (#1321).setFallbackResource from code orlottie_fallbackRes from xml.setApplyingOpacityToLayersEnabled for more info.setMinFrame, setMaxFrame and setMinAndMaxFrame with a marker name.enableHardwareAcceleration with a new setRenderMode API because it has a third (Automatic) option. Refer to the docs for more info.invalidateSelf() from being called and recalculating bounds many times per frame.fetchBitmap() as @NullableLottieComposition.Factory in favor of LottieCompositionFactory.LottieComposition#getImages() to aid in preloading images.playAnimation(start, end). It has been removed in favor of explicit methods for setMinFrame/Progress, setMaxFrame/Progress and setMinAndMaxFrame/Progress followed by an explicit call to playAnimation or resumeAnimation.reverseAnimation and resumeReverseAnimation apis have been removed in favor of play and resume with speed < 0.play(startFrame, endFrame) and play(startProgress, endProgress).enableMergePathsForKitKatAndAbove and read the documentation before using it.LottieAnimationView and LottieDrawableLottieDrawable public again.LottieDrawable is used outside of LottieAnimationView
