Existing hidden methods allow activities to be notified when their
windows have completed animating in. This change adds that capability
to system windows using a ViewTreeObserver callback since system
windows lack an activity token.

The first subsystem to use this is the UserSwitchingDialog which was
previously using a 250 msec timeout to dismiss the dialog. That
deadline was often missed leaving the user with no dialog on the
screen during the transition.

Fixes bug 16661752.

d912e1f6a111fb33118d116bd72da1a328041bca 12-Apr-2014 Jeff Brown <jeffbrown@google.com> Use the display's actual state in the view hierarchy.

Previously, the view hierarchy would suppress drawing whenever the
PowerManager.isScreenOn() method returned false. However, this method
really describes the interactive state of the device rather than the
actual display state. This is especially a problem when there are
multiple displays but it also breaks drawing while in doze mode.

This change makes the view hierarchy consider the actual state of the
display instead on an individual basis.

c4aad01cbbb69c916ef323693e1fd0560b0eccba 23-Feb-2013 Dianne Hackborn <hackbod@google.com> Formalize overscan metrics.

The window manager now maintains and reports a new formal
"overscan insets" for each window, much like the existing
content and visible insets. This is used to correctly
position the various UI elements in the various combination
of layout options. In particular, this allows us to have
an activity that is using fitSystemWindows to have the content
of its UI extend out to the visible content part of the screen
while still positioning its fixed UI elements inside the
standard content rect (and the entire window extending all
the way into the overscan area to fill the screen as desired).

Okay, maybe that is not written so clearly. Well, it made
my head hurt too, so suffer!

The key thing is that windows now need to know about three
rectangles: the overall rectangle of the window, the rectangle
inside of the overscan area, and the rectangle inside of the
content area. The FLAG_LAYOUT_IN_OVERSCAN option controls
whether the second rectangle is pushed out to fill the entire
overscan area.

Also did some improvements to debug dumping in the window
manager.

Add a one way method to notify Views that the window has moved
on the screen. Fixes issues arising from the IME popping up and
translating the window that uses it. Accessibility was left unaware
of these movements and was drawing the box around the wrong widgets.
Similarly PopupWindow used getLocationOnScreen to determine how
much screen real estate was above and below the anchor point to
determine where to put an anchored window.

Fixes bug 6623031.

On some hardware allocating a new graphics buffer is quite
expensive, which blocks updates to the UI. This can cause
glitches when performing window animations.

To reduce these glitches, the view hierarchy will now only
allow itself to be drawn once if its window is being shown
while the window manager is animating, not resuming draws
until it is told that the animation is done.

Bug #6120957

Using this new callback, views can interrupt and resume their
animations or other periodic tasks based on the current state
of the display.

When WindowManagerService's events are enabled/disabled, the state of the
display is dispatched to the known windows. This allows ViewRootImpl to
ignore draw requests until the screen is turned back on. This can potentially
lead to significant battery savings. For instance, a launcher widget showing
a repeating animation will cause the CPU and the GPU to wake up regularly
without this change.

This cleans up how ui flags are managed between the client and window manager.
It still reports the global UI mode state to the callback, but we now only clear
certain flags when the system goes out of a state (currently this just means the
hide nav bar mode), and don't corrupt other flags in the application when the
global state changes.

Also introduces a sequence number between the app and window manager, to avoid
using bad old data coming from the app during these transitions.

1. Views are represented as AccessibilityNodeInfos to AccessibilityServices.

2. An accessibility service receives AccessibilityEvents and can ask
for its source and gets an AccessibilityNodeInfo which can be used
to get its parent and children infos and so on.

3. AccessibilityNodeInfo contains some attributes and actions that
can be performed on the source.

4. AccessibilityService can request the system to preform an action
on the source of an AccessibilityNodeInfo.

5. ViewAncestor provides an interaction connection to the
AccessibiltyManagerService and an accessibility service uses
its connection to the latter to interact with screen content.

6. AccessibilityService can interact ONLY with the focused window
and all calls are routed through the AccessibilityManagerService
which imposes security.

7. Hidden APIs on AccessibilityService can find AccessibilityNodeInfos
based on some criteria. These API go through the AccessibilityManagerServcie
for security check.

8. Some actions are hidden and are exposes only to eng builds for UI testing.

1. Views may setSystemUiVisibility() to recommend that
the system chrome (status bar or other UI) show or hide
itself. (This functionality was previously available only
via the FLAG_FULLSCREEN window flag for some SystemUI
implementations.)

on a view, and find out when the system UI actually
appears or disappears, allowing apps to coordinate the
appearance of their own UI if desired.

a53146c5569f8ff5f7eb55e9ad35d23ddacf2add 07-Sep-2010 Christopher Tate <ctate@google.com> Drag/drop APIs and infrastructure

A View initiates a drag-and-drop operation (hereafter just called a "drag")
by calling its startDrag(ClipData) method. Within the processing of that
call, two callbacks are made into the originating View. The first is to
onMeasureDragThumbnail(). Similarly to the core onMeasure() method, this
callback must respond by calling setDragThumbnailDimension(width, height) to
declare the size of the drag thumbnail image that should be used. Following
this, the View's onDrawDragThumbnail(canvas) method will be invoked to
actually produce the bits of the thumbnail image.

If all goes well, startDrag() will return 'true', and the drag is off and
running. (The other arguments to startDrag() provide reconciliation between
the current finger position and where the thumbnail should be placed on
the screen relative to it.)

Potential receipients of the ClipData behind the drag are notified by a
new dispatch mechanism, roughly parallel to motion event dispatch. The core
routine is the View's onDragEvent(event) callback, with the mechanics of
dispatch itself being routed through dispatchDragEvent(event) -- as in
the case of motion events, the dispatch logic is in ViewGroup, with leaf
View objects not needing to consider the dispatch flow.

Several different event 'actions' are delivered through this dispatch
mechanism:

ACTION_DRAG_STARTED: this event is propagated to every View in every window
(including windows created during the course of a drag). It serves as a
global notification that a drag has started with a payload whose matching
ClipDescription is supplied with the event. A View that is prepared to
consume the data described in this event should return 'true' from their
onDragEvent() method, and ideally will also make some visible on-screen
indication that they are a potential target of the drop.

ACTION_DRAG_ENTERED: this event is sent once when the drag point
enters the View's bounds. It is an opportunity for the View to set up
feedback that they are the one who will see the drop if the finger goes
up now.

ACTION_DRAG_LOCATION: when the drag point is over a given View, that
View will receive a stream of DRAG_LOCATION events, providing an
opportunity for the View to show visual feedback tied to the drag point.

ACTION_DRAG_EXITED: like DRAG_ENTERED, but called when the drag point
leaves the View's bounds. The View should undo any visuals meant to
emphasize their being the hovered-over target.

ACTION_DROP: when the drag ends at a given point, the View under that
point is sent this event, with the full ClipData of the payload.

ACTION_DRAG_ENDED: paralleling the DRAG_STARTED action, this is the global
broadcast that the drag has ended and all Views should return to their
normal visual state. This happens after the DROP event.

e36d6e277e49475076b7872d36ea6a5c5b996e9d 18-Feb-2010 Dianne Hackborn <hackbod@google.com> Work on issue #2263557: PMF3000 showing hybrid of portrait and landscape modes

This is a bunch of reworking of how configuration changes are handled:

- When orientation is changing (for whatever reason), the window manager no
longer tries to pre-emptively compute a new configuration. Instead, it
just determines change is happening and tells the window manager.
- The activity manager is now responsible for giving the window manager the
final configuration it is using. This is both so it knows whem the
activity manager is done with its configuration updates, and so the window
manager can use the "real" configuration.
- When an orientation or other configuration change is happening, freeze the
screen and keep it frozen until the activity manager has given us the
final configuration.
- The window manager can now send new configurations to its clients during
its layout pass, as part of a resize, if it has determined that it has
changed. This allows for a new View.onConfigurationChanged() API for any
view to easily find out when the configuration has changed.
- ViewRoot now also works with the activity thread to make sure the process's
current resources are updated to the new configuration when it receives one
from a window. This ensures that at the time onConfigurationChanged() and
other view callbacks are happening, the correct configuration is in force.
- There is now a sequence number associated with Configuration, which
ActivityThread uses to avoid using stale configurations. This is needed now
that it can receive configurations asynchronously from both the window
manager and activity manager.
- The hack for keeping the locale has been removed, and underlying problem
fixed by having Configuration initialize its locale to "unknown" instead of
a valid default value.

Note: currently only implements an async version (no result), and not yet
actually tested.

Lot of infrastructure for more things to go away when "clear system dialogs"
happens, and now do this when we turn on the lock screen.

19382ac1a4e4e7c23a1346d299368763f149de9c 12-Sep-2009 Dianne Hackborn <hackbod@google.com> Some optizations to wallpaper drawing/scrolling.

First, fix some issues with the final wallpaper bitmap
we use: ensure it is always 16bpp, and make sure dithering
of its bitmap is turned off. We take of dithering
when loading, to make sure we don't use it when drawing.

Also add new APIs to return the wallpaper with the equivalent
of Launcher's old FastBitmapDrawable. As doing this, also load
the default wallpaper the same way as custom ones, taking care to
resize it as needed at load time.

Finally implement a mechanism for the window manager to wait
for the wallpaper to redraw at its new position before returning
from the application's call to change the offset. This ensures
that the wallpaper better tracks the application. Note that there
is a timeout in this wait that is relatively short, and if it
expires we will run for a while without waiting.

Wallpapers can now be just the size of the screen, and get told when their
scroll position should change to do the updating on their own.

4c62fc0e1e5ea9c69a12a7d1cf8b3ec8b2d114a3 09-Aug-2009 Dianne Hackborn <hackbod@google.com> Very primitive wallpapers in a surface.

This is all of the basic pieces:

- The WallpaperService now creates a surface with the window manager for its
contents.
- There is a simple service that displays a bitmap.
- The wallpaper manager takes care of starting and stopping the service.
- The window manager knows about wallpaper windows and how to layer them with
the windows that want to be shown on top of wallpaper.

Lots and lots of issues remain, but at this point you can actually write a
wallpaper service, select it in the UI, and see it behind an activity.
