Workout your tasks with WorkManager
summary
WorkManager arrives as a Jetpack library that guarantees deferrable background work across restarts and Android versions, using JobScheduler/Firebase/AlarmManager under the hood and persisting tasks in a Room DB. It supports chained and parallel work, periodic work with 15‑minute minimum and flex windows, inputs/outputs limited to 10KB, constraints (network, charging, idle), and CoroutineWorker/RxWorker/ListenableWorker integrations; statistics cited: ~50–53% uninstall for crashes and 36% for heavy battery usage.
