The change makes the distinction between VibrationEffect and
CombinedVibratio clearer. The later is a combination of the former with
the extra information about the vibrator ids, allowing effects to be
played in one or more vibrators in parallel or in sequence.
The methods create/start synced where also renamed to parallel (together
with respective builder classes), to indicate they perform one or more
effects in parallel on multiple vibrators. This is also a better match
to the sequential combinations.
This change also deprecates the Context.VIBRATOR_SERVICE in favour of
the new VIBRATOR_MANAGER_SERVICE. The default vibrator can be retrieved
from the manager system service.
Same deprecation applied to InputDevice.getVibrator method.

Currently, the Translation uses feature to determine if we need to
start the translation system service. But our case is like the
content capture not the autofill, the autofill can have the feature
without any service defined and the user can install one later. But
translation isn't, we should need to check config instead of
feature.
The feature will not be used anymore, it's safe to delete it. If we
leave the removal to next OS, it is painful to delete it.

This makes StageCoordinator implement the TransitionHandler
interface.
In general, this currently expects 'enter' transitions to
contain 2 tasks (one in each split). The current UX is undefined
when one only one of the splits is occupied, so for now it will
throw an exception if that case is hit.
There is a split-screen API called startTasks which takes a list
of tasks (currently only supports 2) and associated options and
creates a transition to both enter split-screen and launch those
tasks into their respective stages.
These are the currently accounted-for entrypoints into
the handler interface:
- Core-initiated (handleRequest)
- in split: trigger=HOME that is opening -> full dismiss.
- in split: trigger=task with a stage parent that is last closing in
that stage -> dismiss with other stage onTop
- NOT split: trigger=task with stage parent -> exception
- Shell-initiated
- NOT split: startTasks -> enter split with 2 tasks
- in split: snap-to-dismiss -> dismiss with other stage on top

This is the re re..re-merging of ag/12923546 (where most of that original
message is posted below). This includes various bug fixes.
Slow prefetch requests would block user interactive requests, creating
noticeable sluggishness and unresponsiveness in accessibility services,
especially on the web.
Let's make it so a user interactive requests stops prefetching.
We can't interrupt an API call, but we can stop in between API calls.
On the service side, we have to separate the prefetch callbacks from the
find callback. And we have to make it asynchronous. It does dispatch
intothe main thread, so the AccessibilityCache can remain single threaded.
When the calls are interrupted on the application side,
returnPendingFindAccessibilityNodeInfosInPrefetch checks the find
requests that are waiting in the queue, to see if they can be addressed
by the prefetch results. If they can be, we don't have to call into
potentially non-performant application code. We don't check requests
that have differing prefetch flags (FLAG_INCLUDE_NOT_IMPORTANT_VIEWS,
FLAG_REPORT_VIEW_IDS) that would result in different caches. We satisfy
at most one pending request.
We also make mPendingFindNodeByIdMessages thread-safe and ensure in
ActionReplacingCallback we don't return null results. Merged
ag/13246536, ag/13256330
Messages should be added to PrivateHandler and
mPendingFindNodeIdMessages at the same time to avoid a race condition
where we try removing a message from the handler before it's actually
enqueued. This was causing double recycling
We call into AccessibilityCache from the Binder thread, now that the
cache doesn’t call out to the app main thread with a lock(ag/14020225)

To switch magnification mode, a user has to click the magnifcation
button UI. However magnification button UI is visible only when
there is an user touch interaction or the magnification shortcut
triggered event.
However some a11y services like switch-access or voice-access
can only interact with magnification UI by performing
accessibility actions. To make magnification button showing and
able to interact with a user, we also trigger updating
magnification button UI when an accessibility action is performed.

With Frame Rate Override enabled, an app could get an onDisplayChanged
events which seems redundant. An example would be:
1. Display changed refresh rate to 60Hz - onDisplayChanged was called
2. App's frame rate override changed to 60Hz - onDisplayChanged was called
To avoid sending these redundant events, DisplayManagerGlobal caches
the last DisplayInfo that was reported to the app and based on it it
decides whether to send the event or not.

In dispatchTouchEvent(), the target node is searched by the for loop.
When the TargetAccessibilityFocus flag is set, dispatchTouchEvent
prioritizes finding the accessibility focused node first.
When the accessibility focused node doesn't handle the event, the second
search is done without the TargetAccessibilityFocus flag.
To prepare for the second search, the index is reset when the
accessibility focused node is found.
Currently the index is reset to childrenCount - 1, which is the same as
the initial index of the for loop, but to search the same range as the
first search, we need to reset it to childrenCount, because the actual
second search starts from the next loop.

Previously, it was possible to receive a FrameMetrics callback after the view was already detached from window. In that situation, the mInputEventReceiver is set to null and the object is disposed.
But InputMetricsListener used to store another reference to mInputEventReceiver. So it's own object was never set to null. We would then try to send the timeline to native input receiver, and crash because the native object has already be deleted by the earlier dispose() call.
So the sequence of events was:
dispatchDetachedFromWindow
mInputEventReceiver.dispose()
native input receiver is deleted
InputMetricsListener::onFrameMetricsAvailable
mInputEventReceiver.reportTimeline
try to access a native object using a null pointer
crash
A few options to fix this were investigated:
1) Unregister the observer when mAttachInfo.mThreadedRenderer is set to null.
This is good to do, but it's not sufficient. The problem is that the native call to RenderProxy 'removeObserver' is not serviced immediately, but is posted to be completed sometime in the future. Therefore, the crash would not be fixed by it.
Still, we should always register the observer for the active threadedRenderer, which is done in this CL.
2) Keep a weak reference to mInputEventReceiver inside InputMetricsListener. This would allow InputMetricsListener to check on the status of mInputEventReceiver. When it's disposed, it would be also set to null, so the weak reference resolution would fail.
Unfortunately, 'mInputEventReceiver' is not the only reference to the object of WindowInputEventReceiver. It turns out that the receiver is also stored inside the queued events (see class QueuedInputEvent { private InputEventReceiver mReceiver }). From reviewing ag/153113, it should be OK to remove the receiver from QueuedInputEvent and simply keep track of whether the event is synthesized or not.
But, that change would be too significant to make in this CL. Also, weak references have performance impact, so this may not be desirable anyways.
3) Do not store mInputEventReceiver in InputMetricsListener
The chosen option is to simply use the variable mInputEventReceiver from the outer class. If the receiver is null, we don't notify about the metrics.
