class RemoteListenableDelegatingWorker : ListenableWorker

kotlin.Any
↳	androidx.work.ListenableWorker
	↳	androidx.work.multiprocess.RemoteListenableDelegatingWorker

A worker which can delegate to an instance of RemoteListenableWorker but importantly only constructs an instance of the RemoteListenableWorker in the remote process.

Summary

Public constructors
`RemoteListenableDelegatingWorker( context: Context, workerParameters: WorkerParameters )`

Public functions
`open Unit`	`onStopped()` This method is invoked when this Worker has been told to stop.
`open ListenableFuture<ListenableWorker.Result>`	`startWork()` Override this method to start your actual background processing.

Inherited functions

From androidx.work.ListenableWorker

`Context`	`getApplicationContext()` Gets the application `android.content.Context`.
`open ListenableFuture<ForegroundInfo>`	`getForegroundInfoAsync()` Return an instance of `ForegroundInfo` if the `WorkRequest` is important to the user.
`UUID`	`getId()` Gets the ID of the `WorkRequest` that created this Worker.
`Data`	`getInputData()` Gets the input data.
`Network?`	`@RequiresApi(value = 28) getNetwork()` Gets the `android.net.Network` to use for this Worker.
`@IntRange(from = 0) Int`	`getRunAttemptCount()` Gets the current run attempt count for this work.
`Int`	`@RequiresApi(value = 31) getStopReason()` Returns a reason why this worker has been stopped.
`MutableSet<String>`	`getTags()` Gets a `java.util.Set` of tags associated with this Worker's `WorkRequest`.
`MutableList<String>`	`@RequiresApi(value = 24) getTriggeredContentAuthorities()` Gets the list of content authorities that caused this Worker to execute.
`MutableList<Uri>`	`@RequiresApi(value = 24) getTriggeredContentUris()` Gets the list of content `android.net.Uri`s that caused this Worker to execute.
`Boolean`	`isStopped()` Returns `true` if this Worker has been told to stop.
`ListenableFuture<Void>`	`setForegroundAsync(foregroundInfo: ForegroundInfo)` This specifies that the `WorkRequest` is long-running or otherwise important.
`open ListenableFuture<Void>`	`setProgressAsync(data: Data)` Updates `ListenableWorker` progress.

Public functions

onStopped

open fun onStopped(): Unit

This method is invoked when this Worker has been told to stop. At this point, the com.google.common.util.concurrent.ListenableFuture returned by the instance of startWork is also cancelled. This could happen due to an explicit cancellation signal by the user, or because the system has decided to preempt the task. In these cases, the results of the work will be ignored by WorkManager. All processing in this method should be lightweight - there are no contractual guarantees about which thread will invoke this call, so this should not be a long-running or blocking operation.

startWork

Added in 2.10.0-alpha03

open fun startWork(): ListenableFuture<ListenableWorker.Result>

Override this method to start your actual background processing. This method is called on the main thread.

A ListenableWorker has a well defined execution window to to finish its execution and return a Result. After this time has expired, the worker will be signalled to stop and its com.google.common.util.concurrent.ListenableFuture will be cancelled.

The future will also be cancelled if this worker is stopped for any reason (see onStopped).

Returns
`ListenableFuture<ListenableWorker.Result>`	A `com.google.common.util.concurrent.ListenableFuture` with the `Result` of the computation. If you cancel this Future, WorkManager will treat this unit of work as failed.
