The notification panel uses LayoutTransition to animate changes to
the list of notifications. This works for the items themselves as
items are added or removed; the new/old items animate in/out and the
existing items animate to make or remove space.
But the handle at the bottom of the list (the gray translucent line) does
not play well with these changes. For example, when an item is swiped away
the handle snaps into its new location before the rest of the items have
finished animating.
The problem comes from a constraint of LayoutTransition; it handles changes
to the container it operates on, and to the parent hierarchy all the way up
to the root. However, it cannot animate changes to siblings of the parents.
So when the list resizes due to item changes, the handle (which is in a sibling
of the list) does not animate this change, but just reacts instantly.
The fix is to draw the handle not as a view itself, but rather as part of the
parent container of the list. So as the list animates a resize, the container will
also animate, and any graphics in the container will animate along with it.
No matter what size the container of the list is, the line will be drawn at
the bottom of it.
Issue #7024902 Notification panel animation incorrect when swiping notification out
Change-Id: Ifc412cb6bcdc6ead35993b0320364a2a95a16e11
When the notification panel is opened larger than the list's length,
the penl is put into a "rubber band" mode, to animate the bottom of the
panel back to the end of the list. But the rubber band mode is never
unset, which causes an improper result if another notification is ended,
preventing the panel from resizing to the new, appropriate size of the list.
Fix is to unset the rubber banding flag when the snapping animation finishes.

The UsbDebuggingManager listens to adbd requests and displays a dialog
when the public key authentification fails, for the user to confirm if it
wants to allow USB debugging from the attached host. If the user chooses
to always allow USB debugging, the UsbDebuggingManager writes the public
key to adbd's config file so that the public key authenfication succeeds
next time.

Split WindowManagerImpl into two parts, the WindowManager
interface implementation remains where it is but the global
communications with the window manager are now handled by
the WindowManagerGlobal class. This change greatly simplifies
the challenge of having separate WindowManager instances
for each Context.
Removed WindowManagerImpl.getDefault(). This represents the
bulk of this change. Most of the usages of this method were
either to perform global functions (now handled by WindowManagerGlobal)
or to obtain the default display (now handled by DisplayManager).
Explicitly associate each new window with a display and make
the Display object available to the View hierarchy.
Add stubs for some new display manager API features.
Start to split apart the concepts of display id and layer stack.
since they operate at different layers of abstraction.
While it's true that each logical display uniquely corresponds to a
surface flinger layer stack, it is not necessarily the case that
they must use the same ids. Added Display.getLayerStack()
and started using it in places where it was relatively easy to do.

It looks like we were end()ing the main timing animation in
the middle of the animation (and too many times, at that).

Notifications for background users are hidden from the
panel and status bar.
Still need to add a concept of "any user" notifications (for
things coming from the system) and notification visibility
controls (for access to icons + possibly masked text of
a background user's notifications).

Pulling down anywhere on the status bar when a panel is

Also adjust gesture recorder output to track the settings
panel and annotate it separately.

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).
