Let's say I use a JobService on my current app version. Then in the next app version, I want to delete the JobService class because I no longer need it. Is is safe to do so or do I need to take a phased approach where I keep the JobService class and explicitly cancel the job for some time?
I would like to ask the same about GCMTaskService.
This post got me concerned about it. I would like to know if it's a real concern. Ref: How to Remove an unused GcmTaskService service?
