1. Android Wear Development Lohika Sergii Kozyrev
2. Intro • Wear development environment • Notifications • Wear Apps • Watchfaces • Demo
3. Environment • Enable developer mode • Wear app goes inside apk for release (wear task) • for debug - separate • same version code, same permissions
4. Notifications • Ready for use - standard notifications • NotificationManagerCompat • WearableExteneder for wear specific options
5. Apps • Same well known Android • Components should live as little as possible • 5 sec inactivity, but not in onPause (due to incoming notification) • Always keep in mind how small battery is
6. Communication • Data items: key-value, synchronised, guaranteed • Messages: byte array, no delivery guaranteed, fast
7. UI • GridViewPager and WearableListView • BoxInsetView (layout_box) and WatchViewStub
8. Ambiactive support • wake-lock - BAD, Always on - GOOD (WearableActivity - setAmbientEnabled()) • EXTRA_BURN_IN_PROTECTION and EXTRA_LOWBIT_AMBIENT from onEnterAmbient(Bundle) bundle in WearableActivity
9. WatchFaces • Interactive (Full colors) • Ambiactive (disable background, avoid solid regions, 95% should be black) • out of box screen burning protection • Maintain timer in interactive mode and use auto-tick once per minute in ambient • draw it straight on canvas :)
