This helps reduce the pressure on framework.jar, and makes it clear

Clearly isolated the DreamManagerService and DreamController
responsibilities. DreamManagerService contains just enough logic to
manage the global synchronous behaviors. All of the asynchronous
behaviors are in DreamController.
Added a new PowerManager function called nap() to request the device
to start napping. If it is a good time to nap, then the
PowerManagerService will call startDream() on the DreamManagerService
to start dreaming.
Fixed a possible multi-user issue by explicitly tracking for
which user a dream service is being started and stopping dreams
when the current user changes. The user id is also passed to
bindService() to ensure that the dream has the right environment.
Fix interactions with docks and the UI mode manager. It is
important that we always send the ACTION_DOCK_EVENT broadcast
to the system so that it can configure audio routing and the like.
When docked, the UI mode manager starts a dock app if there is
one, otherwise it starts a dream.
This change resolves issues with dreams started for reasons other
than a user activity timeout.

JB has introduced LockSettingsService. When the phone is
upgrading from ICS, that used another way to store lock
settings, the LockSettingsService needs to import these
settings to store in its database. This happens when the
systemReady() method of this class is called by SystemServer.
The problem resides in the fact that the
DevicePolicyManagerService actually needs to access the
LockSettingsService during its systemReady() initialization,
causing invalid values to be read by it which propagates and
ends up causing a invalid return in the method
isActivePasswordSufficient.
If user had a Google corporate account that enforces password
related policies through Google Apps Device Policy (GADP) app
in ICS, when he upgrades to JB, the GADP will throw a
notification saying that the password doesn't meet the required
policies and needs to be changed, incorrectly, since it wasn't
touched during upgrade.
This fix initializes the LockSettingsService before the
DevicePolicyManagerService, which is the correct way since
the latter uses the first in its initialization. This prevents
this issue to happen, and probably future issues, depending
on the way that LockSettingsService evolves.

When building external storage paths, always include user in path
to enable cross-user paths and aid debugging.
Each Zygote process continues to only have access to the appropriate
user-specific emulated storage through bind mounts. A second set of
mounts continue supporting legacy /sdcard-style paths. For example,
a process running as owner has these mount points:
/storage/emulated_legacy
/storage/emulated_legacy/Android/obb
/storage/emulated/0
/storage/emulated/obb
Since Environment is created before Zygote forks, we need to update
its internal paths after each process launches.

The window manager is no longer responsible for telling the
input system about the display viewport.
Change-Id: I932882bae55decef55f25093bb2a7ebac1620bb1
Added more complete support for logical displays with
support for mirroring, rotation and scaling.
Improved the overlay display adapter's touch interactions.
A big change here is that the display manager no longer relies
on a single-threaded model to maintain its synchronization
invariants. Unfortunately we had to change this so as to play
nice with the fact that the window manager wants to own
the surface flinger transaction around display and surface
manipulations. As a result, the display manager has to be able
to update displays from the context of any thread.
It would be nice to make this process more cooperative.
There are already several components competing to perform
surface flinger transactions including the window manager,
display manager, electron beam, overlay display window,
and mouse pointer. They are not manipulating the same surfaces
but they can collide with one another when they make global
changes to the displays.
Change-Id: I04f448594241f2004f6f3d1a81ccd12c566bf296
Split the DisplayManager into two parts. One part is bound
to a Context and takes care of Display compatibility and
caching Display objects on behalf of the Context. The other
part is global and takes care of communicating with the
DisplayManagerService, handling callbacks, and caching
DisplayInfo objects on behalf of the process.
Implemented support for enumerating Displays and getting
callbacks when displays are added, removed or changed.
Elaborated the roles of DisplayManagerService, DisplayAdapter,
and DisplayDevice. We now support having multiple display
adapters registered, each of which can register multiple display
devices and configure them dynamically.
Added an OverlayDisplayAdapter which is used to simulate
secondary displays by means of overlay windows. Different
configurations of overlays can be selected using a new
setting in the Developer Settings panel. The overlays can
be repositioned and resized by the user for convenience.
At the moment, all displays are mirrors of display 0 and
no display transformations are applied. This will be improved
in future patches.
Refactored the way that the window manager creates its threads.
The OverlayDisplayAdapter needs to be able to use hardware
acceleration so it must share the same UI thread as the Keyguard
and window manager policy. We now handle this explicitly as
part of starting up the system server. This puts us in a
better position to consider how we might want to share (or not
share) Loopers among components.
Overlay displays are disabled when in safe mode or in only-core
mode to reduce the number of dependencies started in these modes.

UserManagerService is now closely tied to PackageManagerService,
sharing the same locks. There is no longer direct access of
Installer by UserManagerService, instead the package manager is

Uses the twilight service to determine the hours of
sunrise and sunset. Shortly after sunset or before sunrise
gradually start to apply a gamma correction factor to the
auto-brightness calculations to make the screen a little
dimmer at night.
The effect is relatively small and is mostly noticeable
in dark rooms. This is just a first pass at the algorithm,
we can tweak the adjustment later to ensure that it has even less
impact in moderate or bright environments.

The major goal of this rewrite is to make it easier to implement
power management policies correctly. According, the new
implementation primarily uses state-based rather than event-based
triggers for applying changes to the current power state.
For example, when an application requests that the proximity
sensor be used to manage the screen state (by way of a wake lock),
the power manager makes note of the fact that the set of
wake locks changed. Then it executes a common update function
that recalculates the entire state, first looking at wake locks,
then considering user activity, and eventually determining whether
the screen should be turned on or off. At this point it may
make a request to a component called the DisplayPowerController
to asynchronously update the display's powe state. Likewise,
DisplayPowerController makes note of the updated power request
and schedules its own update function to figure out what needs
to be changed.
The big benefit of this approach is that it's easy to mutate
multiple properties of the power state simultaneously then
apply their joint effects together all at once. Transitions
between states are detected and resolved by the update in
a consistent manner.
The new power manager service has is implemented as a set of
loosely coupled components. For the most part, information
only flows one way through these components (by issuing a
request to that component) although some components support
sending a message back to indicate when the work has been
completed. For example, the DisplayPowerController posts
a callback runnable asynchronously to tell the PowerManagerService
when the display is ready. An important feature of this
approach is that each component neatly encapsulates its
state and maintains its own invariants. Moreover, we do
not need to worry about deadlocks or awkward mutual exclusion
semantics because most of the requests are asynchronous.
The benefits of this design are especially apparent in
the implementation of the screen on / off and brightness
control animations which are able to take advantage of
framework features like properties, ObjectAnimator
and Choreographer.
The screen on / off animation is now the responsibility
of the power manager (instead of surface flinger). This change
makes it much easier to ensure that the animation is properly
coordinated with other power state changes and eliminates
the cause of race conditions in the older implementation.
The because of the userActivity() function has been changed
so that it never wakes the device from sleep. This change
removes ambiguity around forcing or disabling user activity
for various purposes. To wake the device, use wakeUp().
To put it to sleep, use goToSleep(). Simple.
The power manager service interface and API has been significantly
simplified and consolidated. Also fixed some inconsistencies
related to how the minimum and maximum screen brightness setting
was presented in brightness control widgets and enforced behind
the scenes.
At present the following features are implemented:
- Wake locks.
- User activity.
- Wake up / go to sleep.
- Power state broadcasts.
- Battery stats and event log notifications.
- Dreams.
- Proximity screen off.
- Animated screen on / off transitions.
- Auto-dimming.
- Auto-brightness control for the screen backlight with
different timeouts for ramping up versus ramping down.
- Auto-on when plugged or unplugged.
- Stay on when plugged.
- Device administration maximum user activity timeout.
- Application controlled brightness via window manager.
The following features are not yet implemented:
- Reduced user activity timeout for the key guard.
- Reduced user activity timeout for the phone application.
- Coordinating screen on barriers with the window manager.
- Preventing auto-rotation during power state changes.
- Auto-brightness adjustment setting (feature was disabled
in previous version of the power manager service pending
an improved UI design so leaving it out for now).
- Interpolated brightness control (a proposed new scheme
for more compactly specifying auto-brightness levels
in config.xml).
- Button / keyboard backlight control.
- Change window manager to associated WorkSource with
KEEP_SCREEN_ON_FLAG wake lock instead of talking
directly to the battery stats service.
- Optionally support animating screen brightness when
turning on/off instead of playing electron beam animation
(config_animateScreenLights).

At systemReady time, the window manager needs to obtain values from the lock

The purpose of this change is to remove direct reliance on
SurfaceFlinger for describing the size and characteristics of
displays.
This patch also starts to make a distinction between logical displays
