Configuration.Builder

public Builder()

Creates a new Configuration.Builder.

public final @NonNull Configuration build()

Builds a Configuration object.

public final @NonNull Configuration.Builder setClock(@NonNull Clock clock)

Sets a Clock for WorkManager to calculate schedules and perform book-keeping.

This should only be overridden for testing. It must return the same value as System.currentTimeMillis in production code.

public final @NonNull Configuration.Builder setContentUriTriggerWorkersLimit(int contentUriTriggerWorkersLimit)

Specifies the maximum number of Workers with Constraints.contentUriTriggers that could be enqueued simultaneously.

Unlike the other workers Workers with Constraints.contentUriTriggers must immediately occupy slots in JobScheduler to avoid missing updates, thus they are separated in its own category.

public final @NonNull Configuration.Builder setDefaultProcessName(@NonNull String processName)

Designates the primary process that WorkManager should schedule work in.

public final @NonNull Configuration.Builder setExecutor(@NonNull Executor executor)

Specifies a custom Executor to run Worker.doWork.

If setWorkerCoroutineContext wasn't called then the executor will be used as CoroutineDispatcher to run CoroutineWorker as well.

public final @NonNull Configuration.Builder setInitializationExceptionHandler(
    @NonNull Consumer<@NonNull Throwable> exceptionHandler
)

Specifies a Consumer<Throwable> that can be used to intercept exceptions caused when trying to initialize {@link WorkManager}, that usually happens when WorkManager cannot access its internal datastore.

This exception handler will be invoked on a thread bound to Configuration.taskExecutor.

public final @NonNull Configuration.Builder setInputMergerFactory(@NonNull InputMergerFactory inputMergerFactory)

Specifies a custom InputMergerFactory for WorkManager.

public final @NonNull Configuration.Builder setJobSchedulerJobIdRange(int minJobSchedulerId, int maxJobSchedulerId)

Specifies the range of android.app.job.JobInfo IDs that can be used by WorkManager. WorkManager needs a range of at least 1000 IDs.

JobScheduler uses integers as identifiers for jobs, and WorkManager delegates to JobScheduler on certain API levels. In order to not clash job codes used in the rest of your app, you can use this method to tell WorkManager the valid range of job IDs that it can use.

The default values are 0 and Integer#MAX_VALUE.

@ExperimentalConfigurationApi
public final @NonNull Configuration.Builder setMarkingJobsAsImportantWhileForeground(boolean markAsImportant)

Regulates whether WorkManager should automatically set android.app.job.JobInfo.Builder.setImportantWhileForeground for workers that are eligible to run immediately.

It will have effects only on API levels >= 23.

public final @NonNull Configuration.Builder setMaxSchedulerLimit(int maxSchedulerLimit)

Specifies the maximum number of system requests made by WorkManager when using android.app.job.JobScheduler or android.app.AlarmManager.

By default, WorkManager might schedule a large number of alarms or JobScheduler jobs. If your app uses JobScheduler or AlarmManager directly, this might exhaust the OS-enforced limit on the number of jobs or alarms an app is allowed to schedule. To help manage this situation, you can use this method to reduce the number of underlying jobs and alarms that WorkManager might schedule.

When the application exceeds this limit, WorkManager maintains an internal queue of WorkRequests, and schedules them when slots become free.

WorkManager requires a minimum of Configuration.MIN_SCHEDULER_LIMIT slots; this is also the default value. The total number of slots also cannot exceed 50.

public final @NonNull Configuration.Builder setMinimumLoggingLevel(int loggingLevel)

Specifies the minimum logging level, corresponding to the constants found in Log. For example, specifying Log.VERBOSE will log everything, whereas specifying Log.ERROR will only log errors and assertions.The default value is Log.INFO.

public final @NonNull Configuration.Builder setRemoteSessionTimeoutMillis(
    @IntRange(from = 0, to = 1200000) long timeoutMillis
)

Set how long in milliseconds that a androidx.work.multiprocess.RemoteWorkManager binding to the designated process stays active before timing out and unbinding.

The default timeout is androidx.work.multiprocess.RemoteWorkManager.DEFAULT_SESSION_TIMEOUT_MILLIS and can be configured up to androidx.work.multiprocess.RemoteWorkManager.MAX_SESSION_TIMEOUT_MILLIS. A timeout of 0 will unbind immediately after each call.

public final @NonNull Configuration.Builder setRunnableScheduler(@NonNull RunnableScheduler runnableScheduler)

Specifies the RunnableScheduler to be used by WorkManager.

This is used by the in-process scheduler to keep track of timed work.

public final @NonNull Configuration.Builder setSchedulingExceptionHandler(
    @NonNull Consumer<@NonNull Throwable> schedulingExceptionHandler
)

Specifies a Consumer<Throwable> that can be used to intercept exceptions caused when trying to schedule WorkRequests.

It allows the application to handle a Throwable throwable typically caused when trying to schedule WorkRequests.

This exception handler will be invoked on a thread bound to Configuration.taskExecutor.

public final @NonNull Configuration.Builder setTaskExecutor(@NonNull Executor taskExecutor)

Specifies a Executor which will be used by WorkManager for all its internal book-keeping.

For best performance this Executor should be bounded.

For more information look at androidx.room.RoomDatabase.Builder.setQueryExecutor.

public final @NonNull Configuration.Builder setWorkerCoroutineContext(@NonNull CoroutineContext context)

Specifies a custom CoroutineContext to run CoroutineWorker.doWork. WorkManager will use its own Job with the provided CoroutineContext.

If setExecutor wasn't called then context will be used as Executor to run Worker as well.

public final @NonNull Configuration.Builder setWorkerExecutionExceptionHandler(
    @NonNull Consumer<@NonNull WorkerExceptionInfo> workerExceptionHandler
)

Specifies a WorkerExceptionHandler that can be used to intercept exceptions caused when trying to execute ListenableWorkers.

This exception handler will be invoked on a thread bound to Configuration.taskExecutor.

public final @NonNull Configuration.Builder setWorkerFactory(@NonNull WorkerFactory workerFactory)

Specifies a custom WorkerFactory for WorkManager.

public final @NonNull Configuration.Builder setWorkerInitializationExceptionHandler(
    @NonNull Consumer<@NonNull WorkerExceptionInfo> workerExceptionHandler
)

Specifies a WorkerExceptionHandler that can be used to intercept exceptions caused when trying to initialize ListenableWorkers.

This exception handler will be invoked on a thread bound to Configuration.taskExecutor.
