WorkManager — What Is It?
summary
WorkManager is Jetpack’s unified API for scheduling reliable background work across Android versions and reboots, replacing JobScheduler/Firebase JobDispatcher. It uses Worker subclasses implementing doWork that return Result.success/failure/retry, supports one-off and periodic tasks (minimum 15-minute interval), constraint-based execution (network/charging/battery), observable states, WorkContinuation chaining with input/output data passed between jobs, unique-work policies (REPLACE/KEEP), and parallel branches/joins; it’s not intended for immediate UI or payment tasks.
