public final class RemoteListenableDelegatingWorker extends ListenableWorker

java.lang.Object
   ↳ 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 methods

onStopped

public void onStopped()

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

public @NonNull ListenableFuture<@NonNull ListenableWorker.Result> startWork()

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
@NonNull ListenableFuture<@NonNull 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.
