Interfaces

Provider

A class that can provide the Configuration for WorkManager and allow for on-demand initialization of WorkManager.

ForegroundUpdater

Manages updating android.app.Notifications when a ListenableWorker transitions to running in the context of a foreground android.app.Service.

Operation

An object that provides information about the execution of an asynchronous command being performed by WorkManager.

ProgressUpdater

Updates progress for a androidx.work.ListenableWorker.

RunnableScheduler

Can be used to schedule Runnables after a delay in milliseconds.

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 ListenableWorkers.

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 OneTimeWorkRequests.

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.

WorkQuery

A specification for querying WorkRequests.

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 PeriodicWorkRequests in case of a collision.

ExistingWorkPolicy

An enumeration of the conflict resolution policies available to unique OneTimeWorkRequests in case of a collision.

NetworkType

An enumeration of various network types that can be used as Constraints for work.
