Android 5.0 internals and our inferiority complex
summary
Lollipop’s JobScheduler is a system service that registers jobs (JobInfo) with simple constraints, persists them as XML in /data, and uses small controller components (battery, network, time, idle) implemented as broadcast receivers. The idle controller sets an alarm on screen-off and flips idle after 71 minutes, while stable charging is treated as connected for 2 minutes before triggering jobs. A compatibility library mimics behavior per app using AlarmManager, and GCM Network Manager provides a Play‑services alternative.
