Operation
interface Operation
| androidx.work.Operation |
An object that provides information about the execution of an asynchronous command being performed by WorkManager. Operations are generally tied to enqueue or cancel commands; when you call one of those commands, they occur asynchronously. You can observe or await these commands by using the returned Operation.

Public methods
getResult
@NonNull abstract fun getResult(): ListenableFuture<Operation.State.SUCCESS!>
Gets a ListenableFuture for the terminal state of the Operation. This will only resolve with a State.SUCCESS. The State.FAILURE state will come through as a Throwable on the ListenableFuture. State.IN_PROGRESS will never be reported as it's not a terminal state.
Call ListenableFuture#get() to block until the Operation reaches a terminal state.
| Return | |
|---|---|
ListenableFuture<Operation.State.SUCCESS!> |
A ListenableFuture with information about Operation's State.SUCCESS state. |
getState
@NonNull abstract fun getState(): LiveData<Operation.State!>
Gets a LiveData of the Operation State.
| Return | |
|---|---|
LiveData<Operation.State!> |
A LiveData of the Operation State; you must use LiveData#observe(LifecycleOwner, Observer) to receive updates |
