Add new Activity.isVoiceInteractionRoot() API that an activity can use
to determine whether it is the root activity of a voice interaction
session started by the user's designated voice interaction service.
This is a special new API that apps must explicitly check, because as
with visual activities the model behind an activity should usually be
that it accomplishes its task by interacting with the user (implicitly
getting their approval) rather than trusting that whoever invoked it
is telling it to do what the user once. In the voice world, however,
there are some cases where quick interactions want to allow for immediate
execution without further user involvement, so this API allows for that
without opening up security holes from other applications.

...context and/or screenshot
Added new API to find out what contextual data has been globally disabled.
Also updated various documentation to make it clear what kind of contextual
data you will get (and when it will be null).
Also added a new Activity.showAssist() API because... well, I was already
in there, it was easy to do, it is safe, and maybe people will build cool
things with it.

New APIs allow the voice interaction service to set/retrieve a filter
for which of the show flags are allowed.

TextView is now much smarter about the text it reports, limiting it
to what is visible (plus a bit more). Also add a facility for it to
report where the lines of text are, both as offsets in the text string
and their baselines on screen.

Just forgot to add the request to the active set.
Also eradicate a bunch of old cruft that has been replaced
by the final APIs, and improve voice interaction test to
sit fully on top of the final APIs and have a test for
command request.

...into account when calculating the position information
Actually what we need here is the full transformation matrix, if it
is available. And that means actually computing the location of
views on the screen requires doing this all through transformations,
so the AssistVisualizer has been changed to do this (while still
also keeping the old mechanism for comparison to verify that things
are working correctly).
Also added new properties for elevation and alpha.
And optimized the parcelling of AssistStructure to not write things
that aren't needed; this reduces the parcelled size by about half.

Fix the various view assist related APIs.
Also remove the blockAssist view attribute, and instead use
the window's FLAG_SECURE to drive blocking of the entire
hierarchy (which is semantically correct, and will protect
existing apps that have already indicated they need it).

Issue #19912529: VI: VoiceInteractor callback ClassCastException
Fix to use correct argument.
Issue #19912636: VI: Documentation for VoiceInteractionSession.onBackPressed
Added documentation.
Issue #19912703: VI: VoiceInteractionSession NPE on Abort Request
Maybe fix this -- don't crash if there is no active session.
Issue #19953731: VI: Add value index to...
...android.app.VoiceInteractor.PickOptionRequest.Option
There is now an optional index integer that can be associated with
every Option object.
Issue #19912635: VI: Behavior of startActivity when in voice...
...interaction is unexpected
We now forcibly finish the current voice interaction task whenever
another activity takes focus from it.
Issue #20066569: Add API to request heap dumps
New ActivityManager API to set the pss limit to generate heap
dumps.
Also added app ops for assist receiving structure and screenshot
data, so that we can track when it does these things.

New APIs on ViewAssistStructure all the app to request to
build a sub-tree asynchronously and indicate when it is done
with that. The overall AssistStructure is now only flattened
and transfered on-demand, when the app receiving it requests
its data -- and at that point we can wait for any asynchronous
building to complete.
New AsyncStructure view is a very simple example of using this
to asynchronously build a child view.

New flag you pass in to startSession() to say you want it,
new callback on VoiceInteractionSession to receive it.

Also add API for voice interaction service to control
whether the system should hold a wake lock while it is
working with an activity (and actually *do* hold a wake
lock while doing so, duh!).
And while in there, clean up the launching wake lock to
correctly give blame to the app that is launching.

We now have a formal concept of the session being shown and
hidden, with it being able to continue running while hidden
as long as there is enough RAM.
This changes the flow that a VoiceInteractionSession will
see: onCreate() is when it is first created, onCreateContentView()
is when its UI first needs to be built, onShow() is called each
time it needs to be shown and has the arguments given when the
show request was made (which has been renamed from startSession to
showSession), and then onHide() will be called when the UI is
no longer shown.
The methods show() and hide() now allow a VoiceInteractionSession
subclass to control when it is shown and hidden, working with the
shown state being maintained by the system.

Can switch from a pure overlay at the top of the screen,
to interactive mode with the voice UI drawing at the bottom
and pushing its target activity up like an IME.
Add mechanism to get assist data to the voice interaction UI.
Add some basic visualization of the assist data, outlining
where on the screen we have text.
Add a test ACTION_ASSIST handler, which can propagate the
assist data it gets to the voice interaction session so
you can see what kind of data we are getting from different
apps.

New window layer that voice interaction service windows
go in to. Includes a new voice-specific content rectangle
that voice activities are placed in to.
Add specific animations for this layer, sliding down from
the top (though this can be customized by the voice interaction
service).
Also add the concept of activities running for voice interaction
services for purposes of adjusting the animation used for them,
again sliding from the top, but not (yet?) customizable by the
voice interaction service.

This makes VoiceInteractionSession a more first-class
concept. Now the flow is that a VoiceInteractionService
calls startSession() when it wants to begin a session.
This will result in a new VoiceInteractionSession via the
VoiceInteractionSessionService containing it, and the
session at that point an decide what to do. It can now
show UI, and it is what has access to the startVoiceActivity
API.

On the app side, requests are now composed by subclassing
from various types of Request objects.
On the service side, starting a voice interaction session
involves starting another service that will then manage the
session. This leads the service design much more to what
we want, where the long-running main service is very tiny
and all the heavy-weight transient session work is elsewhere
in another process.

This gives a basic working implementation of a persist
running service that can start a voice interaction when
it wants, with the target activity(s) able to go through
the protocol to interact with it. It may even work when
the screen is off by putting the activity manager in the
correct state to act like the screen is on.
Includes a sample app that is a voice interation service
and also has an activity it can launch.
Now that I have this initial implementation, I think I
want to rework some aspects of the API.
