When an application wishes to do low-priority background work when the
device is otherwise idle (e.g. in a desk dock overnight), it declares
a service in its manifest that requires this permission:
android:permission="android.permission.BIND_IDLE_SERVICE
to launch, and which publishes this intent filter:
<intent-filter>
<action android:name="android.service.idle.IdleService" />
</intent-filter>
This string is declared in the API as IdleService.SERVICE_INTERFACE.
The service must be implemented by extending the new "IdleService"
class, which provides the API through which the system will communicate
with the app.
IdleService declares three methods, two of which are lifecycle callbacks
to the service, and the third of which is for the service itself to
invoke when appropriate. The lifecycle callbacks are
public abstract boolean onIdleStart();
public abstract void onIdleStop();
The first of these is a notification to the service that an idle
maintenance interval has begun. The service can then spin off
whatever non-UI work it wishes. When the interval is over, or if
the OS determines that idle services should be shut down immediately,
the onIdleStop() method will be invoked. The service must shut down
any background processing immediately when this method is called.
Both of these methods must return immediately. However, the OS
holds a wakelock on the application's behalf for the entire period
between the onIdleStart() and onIdleStop() callbacks. This means
that for system-arbitrated idle-time operation, the application does
not need to do any of its own wakelock management, and does not need
to hold any wakelock permissions.
The third method in IdleService is
public final void finishIdle();
Calling this method notifies the OS that the application has finished
whatever idle-time operation it needed to perform, and the OS is thus
free to release the wakelock and return to normal operation (or to
allow other apps to run their own idle services).
Currently the idle window granted to each idle service is ten minutes.
The OS is rather conservative about when these services are run; low
battery or any user activity will suppress them, and the OS will not
choose to run them particularly often.
Idle services are granted their execution windows in round-robin
fashion.

AArch64: Make graphics classes 64-bit compatible
Changes in this patch include
[x] Long is used to store native pointers as they can
be 64-bit.
[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)
[x] AssetAtlasManager is not completely 64-bit compatible
yet. Specifically mAtlasMap member has to be converted
to hold native pointer using long. Added a TODO to
AssetAtlasManager.java to indicate the change required.

The ACTION_EXTERNAL_APPLICATIONS_UNAVAILABLE broadcast now uses the
EXTRA_REPLACING intent extra when it is sent as part of an upgrade operation
on a forward-locked application. Update PackageMonitor to recognize this
new information and express it appropriately to the observer.

Now the per-package proc stats data is also per-app-version-code.
In addition to changing the data structure to have one more
SparseArray and passing a version code all over, this also required
improving how we reset the stats so that we can prune a multi-package
process record back to a single package. Otherwise, as you install
updates to apps, the proc stats data would continue to explode as
the data for each of those app's processes got turned to a
multi-package due to tracking the old and new versions at the
same time.
This also bumps the checkin version code, since the package entries
also include a new field for the app version code.

- Adjust total power use when there is unaccounted power so that our
percentages don't end up > 100%.
- Fix accounting of isolated uids to be against the owning real app
uids.
- Rework how we put cpu use into the battery stats to no longer need
this uid name cache that can confuse the uid it is associated with.
- Finish implementing events in the history, adding a string pool and
reading/writing/dumping them.
- Add first two events: processes starting and finishing.
- Fix alarm manager reporting of wakeup alarms to be adjusted by the
WorkSource associated with the alarm, so they are blamed on the
correct app.
- New "--history" dump option allows you to perform a checkin of
only the history data.
- Fixed BitDescription bug that would cause incorrect printing of
changes in some states.

Transform DisplayManagerService into a SystemService and start cleaning
up other local services that it uses from window manager and input manager.
Clean up service thread initialization.
Remove unnecessary static variables from ActivityManagerService.
It's starting to become clear that we really need a better way to manage
service dependencies. Boot phases don't quite cut it.

Change PowerManagerService to start the pre-recovery service rather
than rebooting directly, when requested to reboot into recovery. Add
a new RECOVERY permission which a caller needs (in addition to REBOOT)
in order to go to recovery.

Refactored SystemServer to get rid of a bunch of legacy cruft related
to how the ServerThread used to be started up.
Create system context first when system server starts. This removes
the tangled initialization order dependency that forced us to start
the activity manager service before most anything else.
Moved factory test related constants into the FactoryTest class.
Partially migrated Installer, ActivityManagerService, and
PowerManagerService to the new SystemService pattern. There's more
work to be done here, particularly around the lifecycle of the
power manager.

Move the BatteryStatsHelper class (which computes power use based
on the raw battery stats) out of the settings app and in to the
framework. It is now used by batterystats dump output to print
the computed power information from its current stats.
This involved a lot of refactoring of the BatteryStatsHelper code
to remove all of the UI dependencies. I also did a bunch of cleanup
in it, such as making all power computations be in terms of mAh.
