Activity.setImmersive(boolean) / android:immersive="bool" are now public.
In addition, if the foreground activity is immersive then an update lock
will be held on its behalf. This lets applications such as movie players
suppress the display of intrusive notifications, OTA-availability dialogs,
and the like while they are displaying content that ought not to be
rudely interrupted.
The update lock aspect of this mode is *advisory*, not binding -- the
update mechanism is not actually constrained; it simply uses this information
in deciding whether/when to prompt the user. It's more a guideline than
a rule.

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.

This adds Resources.getDrawableForDensity() and
Resources.getValueForDensity(). These are needed for applications
to correctly retrieve larger icons such as in launcher when
running on a tablet. We had already exposed the APIs to tell the
application which density to use for app icons on the current
device, but didn't unhide these APIs that allowed you to
actually retrieve them.
This is safe to do without introducing a new API level (as long
as we do it soon) because we know these APIs already exist in
Android 4.0, and there is no reason for anyone to be removing
them when building a device.

The idea is that this is a device which is more-or-less headless. It
might have some limited interaction capabilities, but it's not something
that you want to rely on having.

Update some of the platform documentation to directly link to
relevent support lib docs. Yay!
Also improve BroadcastReceiver documentation to more clearly
discussion security around receivers, and how the support
lib's LocalBroadcastManager can help.

New API to let you build an Intent whose base configuration is correct,
but has an additional "selector" to pick out the specific app that you

Improved quick launch bookmarks to support category-based shortcuts
instead of hardcoding package and class names for all apps.
Added a set of Intent categories for typical applications on the
platform.
Added support for some of the HID application launch usages to
reduce reliance on quick launch for special purpose keys. Some
keyboard vendors have hardcoded launch keys that synthesize
"Search + X" type key combos. The goal is to encourage them
to stop doing this by implementing more of HID.

Traceview showed approximately 10% of total parse time inside the
synthetic 'trampoline' methods generated to provide inner classes
with access to their outer class's private fields. The bottleneck
in this particular case is in XmlBlock and its inner class Parser.
Making the bottlneck outer-class members and methods package-scope
instead of private removes that 10% overhead being spent within
these access trampolines.
Traceview tends to overemphasize the significance of very small
methods such as these trampolines. That said, the measured speed
gain on the ParseLargeXmlResFg op due to this patch is between
5% and 6%.

- IME service now switches between visible and perceptible depending on
whether it is being showm, allowing us to more aggressively free its
memory when not shown.
- The activity display time is no longer delayed by the activity
transition animation.
- New -R (repeat) option for launching activities with the am command.
- Improved some documentation on Loader to be clear about some methods
that apps should not normally call.
- FrameworkPerf test now allows you to select individual tests to run.

Introduce a new concept of "B" services. All running services are
classified as either A or B. B services are later in the LRU list.
Their oom_adj is after the home app. This allows us to better pick
services to kill based on how long they have running, and should
reduce the amount that we end up killing the home app.
This temporarly turns on a debug log when the oom_adj of a process
is changed. Sorry, I know it is noisy. This is needed to try to
track down why some processes are being killed.
Also add a flag to the SyncManager's service binding to allow the
syncing process to be more aggressively killed if it has done UI.
This is to address cases we have seen where sync is causing an 80MB
gmail process to be kept around, preventing other process from running.
Now what will happen is that the syncing process will aggressively be
killed by the system, and can then be restarted in a much lighter-weight
state.
Do a little tweak in the power manager to allow us to still do smooth
brightness changes even when the fancy TV off animation is in use.
And get rid of a debug log in the window manager that was accidentally
left in.

SerialManager: provides access to serial ports
SerialPort: for reading and writing data to and from serial ports
IO with both array based and direct ByteBuffers is supported.
Accessing serial ports requires android.permission.SERIAL_PORT permission
Each platform must configure list of supported serial ports in the
config_serialPorts resource overlay
(this is needed to prevent apps from accidentally accessing the bluetooth
or other system UARTs).
In addition, the platform uevent.rc file must set the owner to the
/dev/tty* files to "system" so the framework can access the port.

- Fix ordering problem in sync manager that would cause its wake
locks to slightly appear in the system process when they should
be fully accounted against the app.
- Allow the system process to have more wake lock names in its
battery stats.
- In the bug report output, print totals of the wake locks for each
process, to make it easier to parse what is being printed for things
like the system process with a huge number of individual wake locks.

The CrossProcessCursorWrapper is a useful building block
for wrapping cursors that will be sent to processes remotely.
It can also transform normal Cursors into CrossProcessCursors
transparently.
The new class fixes common performance problems and bugs
that applications have encountered when implementing
ContentProviders.
