Animate Me, If You Don't Do It for Me Do It for Chet
summary
Demonstrates Android UI animation techniques with sample code (GitHub) that runs from Gingerbread to Lollipop, showing a pulsing action‑bar button, spinning badge, and auto‑expanding panel. Covers concrete APIs: ObjectAnimator to replace handler/frame hacks, ViewPropertyAnimator for single‑line transforms, AnimatedVectorDrawable plus clip/rotate/scale/transition drawables and animated state lists for rich icons, as well as shared‑element activity transitions, RecyclerView item animations, and an interface+factory pattern to separate Gingerbread/IceCream/Lollipop implementations.
