onStopCurrentWork
This will be called if the JobScheduler has decided to stop this job. The job for this service does not have any constraints specified, so this will only generally happen if the service exceeds the job's maximum execution time.
Return
True to indicate to the JobManager whether you'd like to reschedule this work, false to drop this and all following work. Regardless of the value returned, your service must stop executing or the system will ultimately kill it. The default implementation returns true, and that is most likely what you want to return as well (so no work gets lost).
