Reimplemented LottieValueAnimator (#624) This version of LottieValueAnimator replaces all of the animator looping logic with a self-managed Choreographer callback architecture. There are two primary reasons for the change: 1) The conversion from setting frames to setting the currentPlayTime of the value animator often led to tricky floating point and rounding issues (#491, #610) 2) The ValueAnimator APIs and implementation have changed in different platform versions. For example, in some versions, the animator will report as running in the update callbacks and for some, it won't. (#555, #615) There are other benefits as well: 1) Animations can now run independently of the animator duration scale setting. 2) Frame rates are now respected. Animations will now render at the fps specified in After Effects rather than 60fps. I had to bump the minSdk to 16 to support Choreographer.
Lottie is a mobile library for Android and iOS that parses Adobe After Effects animations exported as json with Bodymovin and renders them natively on mobile!
For the first time, designers can create and ship beautiful animations without an engineer painstakingly recreating it by hand. They say a picture is worth 1,000 words so here are 13,000:
Gradle is the only supported build configuration, so just add the dependency to your project build.gradle file:
dependencies { compile 'com.airbnb.android:lottie:2.5.0-rc1' }
