This change shows how much time is spent updating and executing
framework display lists within a frame.
This change also fixes a crash that happnes if you attempt to
perform a dumpsys gfxinfo while the app is drawing (we are telling
developers to use this new tool.)

A recent change to LayoutTransition noop'd animations in non-visible
parents, to avoid artifacts like scaling/moving from (0,0,0,0). But there
was logic in ViewGroup that didn't account for transitions that didn't actually
run an animation, causing a disconnect between the state of a parent (getting ready
to remove an item later) and the state of the transition (not running, therefore
not needing the child to be removed later).
The fix was to detect when the transition did not start and avoid adding the
view to the list of children to be removed later.

This change allows market apps and 3rd parties to supply an activity
that responds to ACTION_ASSIST (e.g. market apps).
It also adds a test app to respond to the ASSIST intent and force
the intent disambiguation dialog to appear.

Extend RemoteControlClient class to enable an applicaton to
specify more information about how it's playing media, now covering
usecases where media playback happens "remotely". This playback
information can be used to set the volume and maximum volume
used remotely.
Declare a new intent and associated extras in Intent,
ACTION_VOLUME_UPDATE, so an application can be notified that
the volume it handles should be updated. It can then use
the new RemoteControlClient.setPlaybackInformation() method
to notify AudioService what the volume is.
Extend AudioService to maintain playback information associated
with the RemoteControlClient information in the stack of
media button event receivers (mRCStack). The information
about the active remote is cached so the stack doesn't have
to be iterated over in order to retrieve remote playback info.
Events to "adjust" the remote volume based on hardware key
presses cause the client application to be notified of
volume updates, and the volume panel to display the volume
set by the app.
Revise which stream type is controlled when none is specified
according to latest guidelines for remote playback.
Update VolumePanel class to support a new pseudo stream type,
AudioService.STREAM_REMOTE_MUSIC, that corresponds to the
remote playback volume, and uses the new "media route" icon.
Enable it to receive asynchronously new volume values for
the remote that will be displayed if the UI is still up,
and ignored otherwise.
Now supports hiding/showing sliders dynamically so remote
volume only appears when AudioService has a remote control
client handling remote volume.
Define new java symbols for the two media route icons.
Modify lockscreen behavior: don't automatically control music
volume when music is active, consider also remote playback.
Still to do:
- playback information set by RemoteControlClient should post
a message for AudioService to update playback information
instead of updating it synchronously

1. The function for finding where the accessibility focus in a virtual
node tree presented by an AccessibilityNodeProvider is not needed
API since the framework already keeps track of the accessibility
focused virtual node in order to draw the focus rectangle. This API
adds unnecessary complexity to developers of AccessibilityNodeProviders.

Improve the API around ActionProvider visibility overriding. Allow the
application to notify whatever is hosting the ActionProvider that
visibility has changed in a way that is friendly to alternate support
library-style reimplementations of MenuItem.
Allow MediaRouter.Callback implementations to add or remove themselves
or other Callbacks during dispatch of callback events.
Make MediaRouteActionProvider track the visibility of corresponding
menu items more accurately.

* Add ActionProvider#overridesItemVisibility and isVisible.
These methods allow an ActionProvider to override the
visibility of a MenuItem that it is bound to. If a MenuItem
has been explicitly hidden by the application, it will not
be visible.
* Change MediaRouteActionProvider to not require a MediaRouter
callback, to avoid extra lifecycle management headaches.

Bug 6598784
The algorithm uses three imbricated loops:
- paragraphs
- span regions (called "blocks" in that description) in these
- characters in these
We can ignore the paragraphs and assume paraStart==0.
The span region loop cuts the text into blocks of text which share
the same set of MetricAffectingSpan spans applied to them. Note that
spanStart and spanEnd represent such a range, and not necessarily an
actual span range.
The third loop then iterates over the characters of these blocks, and creates
a new line (calling out() as soon as the width has been reached.
The core of the problem comes from the 'nextSpanStart' variable.
It is used to restart the block loop from a previous position in case
a line has been created that does not intersect with the current block.
However, in case the current block is larger than the width of the text,
the character loop is going to create other lines of text before we exit the
j-loop. Going back to the block loop, we reset spanStart to the nextSpanStart,
which may be too far back in the text. As a result, the same range of characters
is measured again.
The (spanStart == spanEnd) test was used to handle the case where
nextSpanStart was indeed assigned to a value different than spanEnd.
This fix simplifies this logic and removes the nextSpanStart variable:
When the created line ends before the current block (here < spanStart), we
immediately exit the character loop, re-starting the block loop from the
current position.
Patch 4: added a fix in measured to handle overlapping character ranges.

1. Currently we are providing accessibility focus search algorithm in the
framework and we are also setting accessibility focus from hover. It
appears that implementing a focus search strategy that works for all
accessibility services is non trivial task if feasible. Based on
feedback from the developers of two such services at Google - TalkBack
and BarilleBack - the built in focus search does not quite match what
they need and they would like to implement a custom strategy.
Hence, having APIs for accessibility focus search in the framework does
not make. Therefore, we are hiding this APIs and later will take out the focus
search logic and allow the accessibility service to implement search.
Also putting accessibility focus from hover is tightly integrated with
the focus search since the set of views that get accessibility focus
from hover should be the same as the set of views returned by the
focus search routine. Therefore, we are letting the accessibility service
decide where to put accessibility focus when it gets an accessibility
hover event.

This reverts commit 858491ba13ab5d45a5ec462d002b5856703b1b2b
It turns out that Surface Flinger is supposed to generate fake vsyncs while the screen is off, but sometimes it wasn't working due to a bug. That bug has now been fixed by the following change: I7c6abc23bb021d1dfc94f101bd3ce18e3a81a73e
When the screen is off, we might not receive real vsync pulses from
the hardware which would cause posted Choreographer callbacks to not run.
This is bad because messages in the Looper might be blocked behind a barrier
that is scheduled to be removed by one of those Choreographer callback
(see ViewRootImpl.doTraversals). Until the barrier is removed, those messages
will not run. To prevent starvation of the Looper, we synthesize fake vsync
pulses at a reduced rate whenever the display hardware stops generating them.
This change should fix a variety of rare non-deterministic bugs where
the system might appear to be unresponsive while the screen is off,
and spurious ANRs reported shortly after the screen is turned back on.

* Accept a Context when fetching the names of routes and
categories. This lets string resources resolve at time of access
with the correct configuration. The older versions remain available
that will use the static resources from the application. (There are
enough cases where applications will populate this from external
data that requiring it each time even when it was not initialized
from a resource doesn't seem reasonable.)
* Remove the ability for apps to programmatically select non-user
routes.
* Make MediaRouter.Callback an abstract class instead of an interface.
This will make further extensions easier to keep compatible in the
future.

When expanding the status bar, create one layer per notification instead of
a single giant layer for the pile of notifications. This prevents layer
creation failure when the total height of the notifications is larger
than the maximum allowed texture size in OpenGL ES 2.0.
This change only enables layers on notifications that will be visible
once the notification area is fully expanded.

1. AccessibilityInjector was returning true even if the underlying
JavaScript was not loaded/failed. This may lead to TalkBack getting
stuck in a web view. To avoid this TalkBack requires gran1ularity
change when getting into web view. This is neither advertised nor
shown in the tutorial and which is worse it is inconsistent with
the traversal of the app.
Now if the action fails, false is returned and also the timeout for
handling the action request is increased to 5s. Upon the completion
of this timeout TalkBack may decide to show a wait dialog or just
skip the web content. We are treating this as an ANR.
