Developing Wear OS Watch Faces
summary
Covers Watch Face Format v4, tools and a live demo that builds an APK on the phone, validates it, and pushes it to the watch where it installs and can be set active. Uses Watch Face Designer (Figma plugin), Watch Face Studio and Android Studio; a pack library builds APKs, the watch face validator emits non‑expiring tokens (open source) and the data layer transfers the APK. The Watch Face Push API exposes add/update/remove/setActive and supports default faces, enabling marketplace apps like Facer and editor apps like Poochi; the demo works end‑to‑end.
