* Schedules future runs on an in-app handler. Intended to be used in combination with a persistent
|
|
* {@link Scheduler} to improve responsiveness when the app is open.
|
|
*
|
|
* This should only schedule runs when all constraints are met. Because this only works when the
|
|
* app is foregrounded, jobs that don't have their constraints met will be run when the relevant
|
|
* {@link ConstraintObserver} is triggered.
|
|
*
|
|
* Similarly, this does not need to schedule retries with no delay, as this doesn't provide any
|
|
* persistence, and other mechanisms will take care of that.
