Claim: Google Maps can host fully animated, interactive overlays by moving projection math into the app and bypassing binder IPCs. Implementation uses Web Mercator projection plus matrix transforms and Jetpack Compose graphics layers to render animated markers, do real‑time collision handling, stick‑to‑screen anchors and custom tiles. Performance drops from a profiler‑dominating IPC call with 1,000+ markers to a lightweight in‑process path, but tilt isn’t handled, occasional sync drift or gesture edge cases persist, and tile caching/blinking requires a Compose‑only overlay to mitigate.
