1. The need for sending an accessibility event to announce a context change
which does not cleanly fit into the existing UI transition UI events has
come quite a few time in application development. To avoid retrofitting
accessibility event types that do not semantically match the intent to
just announce a short message this patch is adding specialized event type.
Also a helper method on View is added to sheild developers from knowing
how to construct and send such an event.

Add properties that can be set/retrieved programmatically to match the
XML attributes available.
Also add resource ID versions of Drawable setters for Switch.

Using this new callback, views can interrupt and resume their
animations or other periodic tasks based on the current state
of the display.

Allows applications to propagate multiple URI grants through an
Intent.
Later on, we should probably redefine the share actions to be
based on this ClipData with the old extras-based approach only
there for compatibility. Even if we don't do that, though, this
allows you to do a multi-select share that grants multiple URI
permissions by stuffing the URIs in a ClipData.
Also add some documentation in various places telling people how
they can grant URI permissions.

There are now some new trim memory levels that are sent to
non-background applications as RAM becomes low.
There is a new API for an application to retrieve information
about memory trimming and such on demand.
Fixed various checks against the memory trim level to be
robust (not compare against exact values).

SQLiteDatabase.close() should call releaseReference() rather than
closing the database immediately. SQLiteDatabase should also hold
a reference to itself while performing certain operations to
ensure that they complete normally even if another thread closes
the database at the same time.
Fixed a couple of missing or redundant uses of acquireReference()
related to CursorWindows.
To be honest, the reference counting performed by SQLiteClosable should
not be needed, but we're stuck with it in the API.

MediaActionSound is a helper class for applications that use the
camera, or include camera-like behavior such as taking
screenshots. This class helps applications match the sound-playing
behavior of the Camera.takePicture, MediaRecorder.start, and
MediaRecorder.stop methods.
This is useful for applications that don't use the above methods, but
still logically capture images or video, such as the panorama capture
feature and the video effects in the platform camera application.

The SQLiteDatabase constructor is inaccessible so it is not
possible for applications to subclass it. To remove all possible
remaining temptation to do so, make the class final.

Add Closeable to ParcelFileDescriptor, and always close any incoming

Add SQLiteDatabase.deleteDatabase to delete a database and all
of its auxiliary files.
This method is also used by Context.deleteDatabase and resolves issues
where auxiliary files would get left behind.

When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

An "UpdateLock" works similarly to a wake lock in API: the caller is
providing a hint to the OS that now is not a good time to interrupt
the user/device in order to do intrusive work like applying OTAs.
This is particularly important for headless or kiosk-like products
where ordinarily the update process will be automatically scheduled
and proceed without user or administrator intervention.
UpdateLocks require that the caller hold the new signatureOrSystem
permission android.permission.UPDATE_LOCK. acquire() and release()
will throw security exceptions if this is not the case.
The "is now convenient?" state is expressed to interested parties
by way of a sticky broadcast sent only to registered listeners. The
broadcast is protected; only the system can send it, so listeners
can trust it to be accurate. The broadcast intent also includes a
timestamp (System.currentTimeMillis()) to help inform listeners that
wish to implement scheduling policies based on when the device became
idle.
The API change here is a tiny one: a dump(PrintWriter) method has been
added to the TokenWatcher class to facilitate getting information out
of it for dumpsys purposes. UpdateLock itself is still @hide.

When DrmManagerClient object is created and released many times,
the process suddenly crashes.
The case can happen when we make many thumbnails of
DRM-encrypted contents.
The problem is caused by shortage of file descriptors.
DrmManagerClient releases references of file descriptors
only when GC runs. So file descriptors are kept long time
even after the reference of DrmManagerClient are released.
By introducing DrmManagerClient#release() API,
the problem is solved. An application call this API
when we no longer need to use DrmManagerClient object.
Changes are made by SEMC and Sony.
