Backup/restore now supports app widgets.
An application involved with app widgets, either hosting or publishing,
now has associated data in its backup dataset related to the state of
widget instantiation on the ancestral device. That data is processed
by the OS during restore so that the matching widget instances can be
"automatically" regenerated.
To take advantage of this facility, widget-using apps need to do two
things: first, implement a backup agent and store whatever widget
state they need to properly deal with them post-restore (e.g. the
widget instance size & location, for a host); and second, implement
handlers for new AppWidgetManager broadcasts that describe how to
translate ancestral-dataset widget id numbers to the post-restore
world. Note that a host or provider doesn't technically need to
store *any* data on its own via its agent; it just needs to opt in
to the backup/restore process by publishing an agent. The OS will
then store a small amount of data on behalf of each widget-savvy
app within the backup dataset, and act on that data at restore time.
The broadcasts are AppWidgetManager.ACTION_APPWIDGET_RESTORED and
ACTION_APPWIDGET_HOST_RESTORED, and have three associated extras:
EXTRA_APPWIDGET_OLD_IDS
EXTRA_APPWIDGET_IDS
EXTRA_HOST_ID [for the host-side broadcast]
The first two are same-sized arrays of integer widget IDs. The
_OLD_IDS values are the widget IDs as known to the ancestral device.
The _IDS array holds the corresponding widget IDs in the new post-
restore environment. The app should simply update the stored
widget IDs in its bookkeeping to the new values, and things are
off and running. The HOST_ID extra, as one might expect, is the
app-defined host ID value of the particular host instance which
has just been restored.
The broadcasts are sent following the conclusion of the overall
restore pass. This is because the restore might have occurred in a
tightly restricted lifecycle environment without content providers
or the package's custom Application class. The _RESTORED broadcast,
however, is always delivered into a normal application environment,
so that the app can use its content provider etc as expected.
*All* widget instances that were processed over the course of the
system restore are indicated in the _RESTORED broadcast, even if
the backing provider or host is not yet installed. The widget
participant is responsible for understanding that these are
promises that might be fulfilled later rather than necessarily
reflecting the immediate presentable widget state. (Remember
that following a cloud restore, apps may be installed piecemeal
over a lengthy period of time.) Telling the hosts up front
about all intended widget instances allows them to show placeholder
UI or similarly useful information rather than surprising the user
with piecemeal unexpected appearances.
The AppWidgetProvider helper class has been updated to add a new
callback, onRestored(...), invoked when the _RESTORED broadcast
is received. The call to onRestored() is immediately followed by
an invocation of onUpdate() for the affected widgets because
they will need to have their RemoteViews regenerated under the
new ID values.

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.

This makes transport controls a primitive interface on sessions with
a way to create the performer, register callbacks, and send commands
and updates between controllers and performers. This still needs some
cleanup but has been tested with OneMedia.

These new keys behave in similarly to KEYCODE_POWER but do not
simply toggle between awake and asleep states.
Sleep puts the device to sleep if it is awake.
Wakeup wakes up the device if it is asleep.

The managed profile provisioning app completes provisioning (creating the profile, installing the mdm on the secondary user, setting the mdm as the profile owner, removing unneeded apps from secondary user, removing mdm from the primary user). Then it sends a notification that the provisioning has completed across to the new profile. If the mdm, which is now installed on the profile wants to be notified that provisioning has completed it needs to implement this callback method.

addExtras allows merging with exiting set extras instead of replacing
them. This matches the similar function putExtras in Intent.
Both functions are useful for multi-stage notification building logic.

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.
