Schedules and configures jobs to be executed by a {@link JobScheduler}.

{@link MyJobService} can send messages to this via a {@link Messenger} that is sent in the Intent that starts the Service.

Executed when user clicks on SCHEDULE JOB.

Executed when user clicks on CANCEL ALL.

Executed when user clicks on FINISH LAST TASK.

A {@link Handler} allows you to send messages associated with a thread. A {@link Messenger} uses this handler to communicate from {@link MyJobService}. It's also used to make the start and stop views blink for a short period of time.



Service to handle callbacks from the JobScheduler. Requests scheduled with the JobScheduler ultimately land on this service's "onStartJob" method. It runs jobs for a specific amount of time and finishes them. It keeps the activity updated with changes via a Messenger.

When the app's MainActivity is created, it starts this service. This is so that the activity and this service can communicate back and forth. See "setUiCallback()"
