...services get out of app idle
Introduce a new process state to even better distinguish foreground
services from other states. Rework the INTERACTION reporting to
usage stats to do it less when the screen is off -- require that
an app sit in the foreground service or top activity state for
at least 30 minutes before we consider it an interaction.
Also eradicate a bunch of logging in package manager.
