We Suspend This Program for an Important Announcement
summary
Android deprecates sync task in API level R (Android 11) and recommends Kotlin coroutines as a replacement; coroutines claim structured concurrency, cancellation, and lightweight suspension. Examples include converting WorkManager workers from blocking or listenable futures to a coroutine worker (reducing ~20 lines to ~3), Room and Retrofit offering suspend APIs, adapters for CompletableFuture and Tasks, and a demo where Android Studio 4.1 Database Inspector shows live DB edits updating a Flow in the UI. Expect state flow and shared flow for multi-subscriber sharing.
