A Slice of Pie
summary
Slices are a Jetpack mini-UI that expose app actions in Search and Assistant and are not GA yet, so testing uses preview slices and cached responses with configurable timeouts. Implementation uses a SliceProvider content provider via onBindSlice content provider callbacks, notifyChange to refresh UI, and a Kotlin DSL built on a Java builder with a DSL marker to prevent nested contexts. Design focuses on single-task headers, grids, toggles and fast responses; use Google Sign‑in, Smart Lock, Autofill and Auto Backup to cut friction—Netflix reports 20% fewer support requests.
