Shooting a “Glance” at App Widgets
summary
Covers the Glance library that converts its own composables into RemoteViews and wear tiles, clarifies that Glance composables are distinct from Compose UI, and shows concrete behavior: four actions (start activity, broadcast, service, runCallback), state stored with DataStore via local/currentState and updateAppWidgetState, a click-counter demo that passes an increment through action parameters and updates the widget, three sizing strategies including three size modes (single, exact, responsive), dynamic colors on Android 12+/API 31 with resource fallbacks, and compatibility down to API 23 while still alpha.
