Learn Some New Moves: Advanced Android Animation
summary
Animated vector drawables, Shapeshifter and Lottie are shown working end to end: vector path morphing (now supported back to API 14 via support library 25.x), After Effects → JSON → Lottie playback, and a web editor to reconcile incompatible SVG paths. Platform changes yield measurable wins: native vector rewrite gives ~80% faster path parsing and ~40% faster morphing, moving vector animation to the render thread produces about six frames in 100 ms (~16 ms/frame) versus one frame on the UI thread, and the physics library exposes spring+fling primitives and ConstraintLayout+TransitionManager patterns.
