Slice Your App: Inside Slices and How to build it
summary
Explains how Slices are implemented as a ContentProvider subclass that must return a template-based Slice within 2 seconds (no blocking network or DB), so apps return a quick placeholder then fetch data async and call notifyChange to update the Slice. Uses Jetpack Slice Builder KTX and integrates with Firebase App Indexing so Search/Assistant can surface Slices. Notes permission-grant flow for requesting app, shows Slice Viewer for debugging, and warns testing is brittle due to PendingIntent hashes and time fields.
