Allow apps to bypass Power Save restrictions when launched from a Notification's PendingIntent.
This scenario typically happens when the device is on Doze Mode and a
notification action is triggered from a Wear device.
In a nutshell, the workflow is:
- ProcessRecord has a flag telling whether a process has "whitelist
management" privileges.
- When NotificationManager binds a new NotificationListenerService, it
sets the BIND_ALLOW_WHITELIST_MANAGEMENT flag.
- On bind(), ActiveService asserts that only system apps can set that
flag.
- On computeOomAdjLocked(), ActivityManagerService sets the
ProcessRecord flag if necessary.
- Upon creating a notification, NotificationManager calls AM to mark its
PendingIntents as coming from a notification.
- When PendingIntentRecord sends it to the target, it checks if it's
from a notification and if so calls AM to do the temp whitelist.
- On unbind(), ActiveService removes the ProcessRecord flag if necessary.
