Classes

ArrayCreatingInputMerger	An `InputMerger` that attempts to merge the inputs, creating arrays when necessary.
Configuration	The Configuration object used to customize `WorkManager` upon initialization.
Constraints	A specification of the requirements that need to be met before a `WorkRequest` can run.
CoroutineWorker	A ListenableWorker implementation that provides interop with Kotlin Coroutines.
Data	A persistable set of key/value pairs which are used as inputs and outputs for `ListenableWorker`s.
DelegatingWorkerFactory	A `WorkerFactory` which delegates to other factories.
ForegroundInfo	The information required when a `ListenableWorker` runs in the context of a foreground service.
InputMerger	An abstract class that allows the user to define how to merge a list of inputs to a `ListenableWorker`.
InputMergerFactory	A factory object that creates `InputMerger` instances.
ListenableWorker	A class that can perform work asynchronously in `WorkManager`.
OneTimeWorkRequest	A `WorkRequest` for non-repeating work.
OverwritingInputMerger	An `InputMerger` that attempts to add all keys from all inputs to the output.
PeriodicWorkRequest	A `WorkRequest` for repeating work.
RxWorker	RxJava2 interoperability Worker implementation.
WorkContinuation	A class that allows you to chain together `OneTimeWorkRequest`s.
Worker	A class that performs work synchronously on a background thread provided by `WorkManager`.
WorkerFactory	A factory object that creates `ListenableWorker` instances.
WorkerParameters	Setup parameters for a `ListenableWorker`.
WorkInfo	Information about a particular `WorkRequest` containing the id of the WorkRequest, its current `State`, output, tags, and run attempt count.
WorkManager	WorkManager is a library used to enqueue deferrable work that is guaranteed to execute sometime after its `Constraints` are met.
WorkRequest	The base class for specifying parameters for work that should be enqueued in `WorkManager`.

Enums

BackoffPolicy	An enumeration of backoff policies when retrying work.
DirectExecutor	A simple Executor.
ExistingPeriodicWorkPolicy	An enumeration of the conflict resolution policies available to unique `PeriodicWorkRequest`s in case of a collision.
ExistingWorkPolicy	An enumeration of the conflict resolution policies available to unique `OneTimeWorkRequest`s in case of a collision.
NetworkType	An enumeration of various network types that can be used as `Constraints` for work.
