  - onBind

@Nullable
public final IBinder onBind(Intent intent)

    Throws UnsupportedOperationException because this service is not designed to be bound.
    
    Specified by:
    
    onBind in class Service
  - getDownloadManager
```
protected abstract DownloadManager getDownloadManager()
```
    Returns a DownloadManager to be used to downloaded content. Called only once in the life cycle of the process.
  - getScheduler
```
@Nullable
protected abstract 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 Scheduler supports 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.
  - getForegroundNotification
```
protected abstract Notification getForegroundNotification(List<Download> downloads,
                                                          @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:
    
    downloads - The current downloads.
    
    notMetRequirements - Any requirements for downloads that are not currently met.
    
    Returns:
    
    The foreground notification to display.
  - invalidateForegroundNotification
```
protected final void invalidateForegroundNotification()
```
    Invalidates the current foreground notification and causes getForegroundNotification(List, int) to be invoked again if the service isn't stopped.
