A Service for downloading media.

Apps with target SDK 33 and greater need to add the android.permission.POST_NOTIFICATIONS permission to the manifest and request the permission at runtime before starting downloads. Without that permission granted by the user, notifications posted by this service are not displayed. See the official UI guide for more detailed information.

Protected constructors

DownloadService

protected DownloadService(int foregroundNotificationId)

Creates a DownloadService.

If foregroundNotificationId is FOREGROUND_NOTIFICATION_ID_NONE then the service will only ever run in the background, and no foreground notification will be displayed.

If foregroundNotificationId is not FOREGROUND_NOTIFICATION_ID_NONE then the service will run in the foreground. The foreground notification will be updated at least as often as the interval specified by DEFAULT_FOREGROUND_NOTIFICATION_UPDATE_INTERVAL.

Parameters
`int foregroundNotificationId`	The notification id for the foreground notification, or `FOREGROUND_NOTIFICATION_ID_NONE` if the service should only ever run in the background.

DownloadService

protected DownloadService(
    int foregroundNotificationId,
    long foregroundNotificationUpdateInterval
)

Creates a DownloadService.

Parameters
`int foregroundNotificationId`	The notification id for the foreground notification, or `FOREGROUND_NOTIFICATION_ID_NONE` if the service should only ever run in the background.
`long foregroundNotificationUpdateInterval`	The maximum interval between updates to the foreground notification, in milliseconds. Ignored if `foregroundNotificationId` is `FOREGROUND_NOTIFICATION_ID_NONE`.

DownloadService

protected DownloadService(
    int foregroundNotificationId,
    long foregroundNotificationUpdateInterval,
    @Nullable String channelId,

`@Nullable String channelId`	An id for a low priority notification channel to create, or `null` if the app will take care of creating a notification channel if needed. If specified, must be unique per package. The value may be truncated if it's too long. Ignored if `foregroundNotificationId` is `FOREGROUND_NOTIFICATION_ID_NONE`.
`@StringRes int channelNameResourceId`	A string resource identifier for the user visible name of the notification channel. The recommended maximum length is 40 characters.

Protected methods

getDownloadManager

protected abstract DownloadManager getDownloadManager()

Returns a DownloadManager to be used to downloaded content. For each concrete download service subclass, this is called once in the lifecycle of the process when onCreate is called on the first instance of the service. If the service is destroyed and a new instance is created later, the new instance will use the previously returned DownloadManager without this method being called again.

getForegroundNotification

protected abstract Notification getForegroundNotification(
    List<Download> downloads,
    @Requirements.RequirementFlags int notMetRequirements
)

Returns a notification to be displayed when this service running in the foreground.

Download services that do not wish to run in the foreground should be created by setting the foregroundNotificationId constructor argument to FOREGROUND_NOTIFICATION_ID_NONE. This method is not called for such services, meaning it can be implemented to throw UnsupportedOperationException.

Parameters
`List<Download> downloads`	The current downloads.
`@Requirements.RequirementFlags int notMetRequirements`	Any requirements for downloads that are not currently met.

Returns
`Notification`	The foreground notification to display.

getScheduler

protected abstract @Nullable Scheduler getScheduler()

Returns a Scheduler to restart the service when requirements for downloads to continue are met.

This method is not called on all devices or for all service configurations. When it is called, it's called only once in the life cycle of the process. If a service has unfinished downloads that cannot make progress due to unmet requirements, it will behave according to the first matching case below:

If the service has foregroundNotificationId set to FOREGROUND_NOTIFICATION_ID_NONE, then this method will not be called. The service will remain in the background until the downloads are able to continue to completion or the service is killed by the platform.
If the device API level is less than 31, a Scheduler is returned from this method, and the returned Schedulersupports all of the requirements that have been specified for downloads to continue, then the service will stop itself and the Scheduler will be used to restart it in the foreground when the requirements are met.
If the device API level is less than 31 and either null or a Scheduler that does not support all of the requirements is returned from this method, then the service will remain in the foreground until the downloads are able to continue to completion.
If the device API level is 31 or above, then this method will not be called and the service will remain in the foreground until the downloads are able to continue to completion. A Scheduler cannot be used for this case due to Android 12 foreground service launch restrictions.

invalidateForegroundNotification

protected final void invalidateForegroundNotification()

Invalidates the current foreground notification and causes getForegroundNotification to be invoked again if the service isn't stopped.
