1. The old introspection model was allowing querying only the active window
which is the one the user is touching or the focused one if no window is
touched. This was limiting as auto completion drop downs were not inspectable,
there was not way to know when the IME toggles, non-focusable windows were
not inspectable if the user taps them as until a screen-reader starts
introspecting the users finger is up, accessibility focus was limited to
only one window and the user couldn't use gestures to visit the whole UI,
and other things I can't remember right now.
The new APIs allow getting all interactive windows, i.e. ones that a
sighted user can interact with. This prevents an accessibility service
from interacting with content a sighter user cannot. The list of windows
can be obtained from an accessibility service or the host window from an
accessibility node info. Introspecting windows obey the same rules for
introspecting node, i.e. the service has to declare this capability
in its manifest.
When some windows change accessibility services receive a new type
of event. Initially the types of windows is very limited. We provide
the bounds in screen, layer, and some other properties which are
enough for a client to determined the spacial and hierarchical
relationship of the windows.
2. Update the documentation in AccessibilityService for newer event types.
3. LongArray was not removing elements properly.
4. Composite accessibility node ids were not properly constructed as they
are composed of two ints, each taking 32 bits. However, the values for
undefined were -1 so composing a 64 long from -1, -1 prevents from getting
back these values when unpacking.
5. Some apps were generating inconsistent AccessibilityNodeInfo tree. Added
a check that enforces such trees to be well formed on dev builds.
6. Removed an necessary code for piping the touch exploration state to
the policy as it should just use the AccessibilityManager from context.
7. When view's visibility changed it was not firing an event to notify
clients it disappeared/appeared. Also ViewGroup was sending accessibility
events for changes if the view is included for accessibility but this is
wrong as there may be a service that want all nodes, hence events from them.
The accessibility manager service takes care of delivering events from
not important for accessibility nodes only to services that want such.
8. Several places were asking for prefetching of sibling but not predecessor
nodes which resulted in prefetching of unconnected subtrees.
9. The local AccessibilityManager implementation was relying on the backing
service being ready when it is created but it can be fetched from a context
before that. If that happens the local manager was in a broken state forever.
Now it is more robust and starts working properly once the backing service
is up. Several places were lacking locking.

- Add new audio restriction layer to app-ops. Restrictions add
additional constraints to audio operations at a stream-level.
Restrictions do not affect the persistable state, and are purely
additive: that is, they can only impose additional contstraints, not
enable something that has already been disabled. Restrictions
also support a whitelisted set of exempt package names.
- Add new audio stream-level checks to app-ops.
- Implement a provisional OP_PLAY_AUDIO suppression to three
java entry points MediaPlayer, AudioTrack, & SoundPool.
- Enhance vibrator api to take stream information as an optional
hint - the constants correspond to AudioManager stream types.
OP_VIBRATE now supports the stream-level restriction check.
- Simplify Vibrator subclasses by adding default implementations
for two .vibrate calls.
- Migrate NoMan's zen-mode control to use the new app-ops
stream-level restriction mechanism.

On some products, it may not make sense to use the accelerometer
to perform auto-rotation. In that case, the product's config.xml
framework resource overlay should set config_supportAutoRotation
to false.
Setting this to false also disables auto-rotation settings.

Original commit message:
Add swipe-to-dismiss support to PhoneWindow.
This adds a new window feature -- FEATURE_SWIPE_TO_DISMISS -- and a
theme attribute to activate that feature. When the feature is
activated, a SwipeDismissLayout is inflated as the DecorView layout.
SwipeDismissLayout intercepts touch events and steals ones that are
large swipes to the right if its children don't. PhoneWindow
registers handlers that listen for these swipe events, translate the
window when necessary, and finish the activity at the end of the
gesture.

When a doze component has been specified in a config.xml resource
overlay, the power manager will try to start a preconfigured dream
whenever it would have otherwise gone to sleep and turned the
screen off. The dream should render whatever it intends to show
then call startDozing() to tell the power manager to put the display
into a low power "doze" state and allow the application processor
to be suspended. The dream may wake up periodically using the
alarm manager or other features to update the contents of the display.
Added several new config.xml resources related to dreams and dozing.
In particular for dozing there are two new resources that pertain to
decoupling auto-suspend mode and interactive mode from the display
state. This is a requirement to enable the application processor
and other components to be suspended while dozing. Most devices
do not support these features today.
Consolidated the power manager's NAPPING and DREAMING states into one
to simplify the logic. The NAPPING state was mostly superfluous
and simply indicated that the power manager should attempt to start
a new dream. This state is now tracked in the mSandmanSummoned field.
Added a new DOZING state which is analoguous to DREAMING. The normal
state transition is now: AWAKE -> DREAMING -> DOZING -> ASLEEP.
The PowerManager.goToSleep() method now enters the DOZING state instead
of immediately going to sleep.
While in the doze state, the screen remains on. However, we actually
tell the rest of the system that the screen is off. This is somewhat
unfortunate but much of the system makes inappropriate assumptions
about what it means for the screen to be on or off. In particular,
screen on is usually taken to indicate an interactive state where
the user is present but that's not at all true for dozing (and is
only sometimes true while dreaming). We will probably need to add
some more precise externally visible states at some point.
The DozeHardware interface encapsulates a generic microcontroller
interface to allow a doze dream for off-loading rendering or other
functions while dozing. If the device possesses an MCU HAL for dozing
then it is exposed to the DreamService here.
Removed a number of catch blocks in DreamService that caught Throwable
and attempted to cause the dream to finish itself. We actually just
want to let the process crash. Cleanup will happen automatically if
needed. Catching these exceptions results in mysterious undefined
behavior and broken dreams.

Instead of keeping track of confirmations per-package, track
a global confirmation per-user. If the panic signal is received,
reshow the cling at most once per-user per-reboot.
Ensure the nav bar becomes visible after the panic signal.
Usually this happens as a side effect of showing the keyguard.
However, in the case where there is no keyguard (Security = None)
show the transient nav bar temporarily as a hint.
Also listen to the correct observer uri to pick up confirmation
setting changes.

* Add theme attributes for specifying a top-level TransitionManager
for an activity window.
* Add window feature for automatic content transitions. This
automatically assigns/creates a Scene for setContentView calls.
* Add named transitions. This allows apps to define APIs for
handshake-agreements about which exit/entrance transitions to play.
* Add new transition type for ActivityOptions. This lets the system
use ActivityOptions to communicate transition specifics and
arguments to the called activity.
* Have ActivityManager pass appropriate ActivityOptions through to the
called Activity. Have the called activity call back into the caller
to let it know which transition of a possible requested set was
chosen.
Still to do:
* Define and pass arguments for transitions. This will require
defining a Parcelable version of TransitionValues and deciding how
much leeway apps should have for these things.
* Determine how to appropriately filter the ActivityOptions bundle so
that only appropriate data reaches the target.
* Determine if generalizing the auto-Scenes functionality to
ViewGroups is appropriate.
