[Removed API] Removed the
setScale(float)APIs fromLottieAnimationViewandLottieDrawable. 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 useLottieDrawable#drawdirectly. -
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:
- The hardware/software distinction happened at the LottieAnimationView level. That means that consumers of LottieDrawable (such as lottie-compose) had no way to choose a render mode.
- Dedicated memory for Lottie was always allocated. In the software case, it would be a bitmap that is the size of the LottieAnimationView and in the hardware case, it was a dedicated hardware layer.
Benefits as a result of this change:
- Reduced memory consumption. In the hardware case, no new memory is allocated. In the software case, Lottie will create a bitmap that is the intersection of your View/Composition bounds mapped with the drawing transformation which often yields a surface are that is smaller than the entire LottieAnimationView.
- lottie-compose now supports setting a RenderMode.
- Custom uses of LottieDrawable now support setting a RenderMode via setRenderMode.
-
Lottie can now render outside of its composition bounds. To allow this with views such as LottieAnimationView, set
clipToCompositionBoundsto false onLottieDrawableorLottieAnimationViewandclipChildrento false on the parent view. For Compose, use theclipToCompositionBoundsparameter. -
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).

- Added support for loading an animation from a zip file that contains the json as well as images.
- URLs supports zip files as well as json files.
- Deprecated
LottieComposition.Factoryin favor of LottieCompositionFactory.- The new factory methods make it easier to catch exceptions by separating out success and failure handlers. Previously, catching exceptions was impossible and would crash your app.
- All APIs now have a mandatory cacheKey that uses an LRU cache rather than a strong/weak ref cache.
- If the same animation is fetched multiple times in parallel, the same task will be returned. This will be massively helpful for animations that are loaded in a list.
- InputStreams are now always closed even if you use the old APIs. Please be aware if you were using this while upgrading.
- Added support for miter limit.
- [Sample App] Added the ability to load a file from assets.
- Fixed a timing issue when there was time stretch on a masked layer.
- Fixed support for Android P.
- Make a best-effort attempt at rendering shapes in which the number of vertices changes rather than crashing.
- Fixed a bug in which the inner radius animation of a polystar wouldn't update.

- Fixed a bug that would ignore setting minFrame to 0 before the composition was set (#820).
- Prevented Lottie from drawing a recycled bitmap (#828).
- Added support for targeting Android P
- Fixed a potential dangling Choreographer callback (#775)
- Fixed end times for layers/animations. Before, if the layer/animation out frame was 20, it would fully render frame 20. This is incorrect. The last rendered frame should be 19.999... in this case. This should make Lottie reflect After Effects more accurately. However, if you are getting the frame in onAnimationEnd or onAnimationRepeat, it will be one less than it used to be.
- Added support for base64 encoded images directly in the json instead of the filename. They are 33% larger than their equivalent image file but enables you to have images with a single file.
- Fixed a lint error about KeyPath visibility.
- A few min/max progress bug fixes.
- Prevent autoPlay from starting before the animation was attached to the window. This caused animations in a RecyclerView to start playing before they were on screen.

- Min/Max frames are clipped to the composition start/end
- setProgress takes into account start and end frame
- Totally new sample app!
- Rebuilt from the ground up.

- Can open zip files with images from lottiefiles, even with qr scanning.
- Change speed
- Fixed a regression with ellipse direction
- Removed framerate restriction introduced in 2.5.0 that caused Lottie to attempt to render at the After Effects framerate. This caused animations to appear unexpectedly janky in most cases.
- Many minor bug fixes around setting min/max frames
- Removed @RestrictTo on LottieValueCallback
- Improved thread safety of animation listeners
- Fixed looping when the animation speed is reversed
- Added the ability to dynamically change properties at runtime. See docs for more info. This feature removed the existing APIs for changing the color dynamically with a color filter. Refer to the docs for migration info from existing ColorFilter APIs.
- Added a setRepeatMode and setRepeatCount (Thanks Fabio Nuno!).
- Completely overhauled json deserialization. Deserializing a composition takes half as long and can deserialize much larger json files (tested 50mb) without ooming.
- Overhauled the underlying time animator. It now:
- More accurately handles setFrame/getFrame/minFrame/maxFrame APIs. There were cases where they could be off by one before.
- Renders at the fps specified by After Effects.
- Added docs and clearer rules around animatedValue and animatedFraction in animator callbacks.
- API to remove all animator listeners.
- Adhere to the Animatable interface.

LottieComposition#getImages()to aid in preloading images. - Added support for text baseline.
- Prevented a crash when setting min frame > previous max frame.
- Fixed some bugs in subtract masks.
- Fixed some animation clamping when an animation was longer than its parent and time stretched.
- Stopped applying time stretch to a layer transform.
- Animator fixes:
- Previously, some usages of lottie animator apis/api listeners would cause unexpected behavior, especially calling apis from listener callbacks.
- This is breaking change if you use
playAnimation(start, end). It has been removed in favor of explicit methods forsetMinFrame/Progress,setMaxFrame/ProgressandsetMinAndMaxFrame/Progressfollowed by an explicit call toplayAnimationorresumeAnimation. reverseAnimationandresumeReverseAnimationapis have been removed in favor ofplayandresumewithspeed< 0.- If you have created hack around these limitations or complex animator chaining, please test your animations after updating.
- Set an animation from R.raw (res/raw) if you want static references to your animation files. This can help prevent mismatches between api calls and file names. Thanks @cyrilmottier!
