This reserves a range of uids (for each user) in which these processes
run. These uids are not associated with an application, so they
effectively run with no permissions. When a Service requests to
run in such a process through android:isolatedProcess="true", each
time it is brought up a new isolated process is started with its
own unique uid.
What we have so far gives us the basic infrastructure; more work
remains to further lock down what these uids have access to.

This class has existed since ICS, but was hidden. This change
just makes it public API.
Also, cleaned up some internal javadocs.

This new setting allows users to set a scale factor for the
duration and startDelay of all Animator-based animations. This
setting is very similar to the Transition animation scale and
Window animation scale settings, except this one applies specifically
to Animator animations. The property is only accessible by users
through the Settings UI, not programmatically. The value applies
system-wide and is picked up per-process at the time of the first
ValueAnimator construction.
This is an update to a previous CL; this approach uses the WindowManager
to store the animator scale settings, instead of SystemProperties.

Before now, receiving a broadcast would cause a process to be hoisted
to foreground priority / cgroup. This is no longer the case: broadcasts
by default are handled in the background, with a suitably increased
timeout interval. When a given broadcast needs to be dealt with in a
more timely manner, the issuer can set the new FLAG_BROADCAST_FOREGROUND
flag on the Intent, which will produce the old foreground-priority
behavior.
To avoid priority inversions, foreground broadcasts are tracked on a
separate outgoing queue and can be in flight simultaneously with a
background-priority broadcast. If there is already a background-level
broadcast in flight to a given app and then a foreground-level one is
dispatched to that app, the app [and its handling of both broadcasts]
will be properly hoisted to foreground priority.
This change is also essentially the first step towards refactoring the
broadcast-handling portions of the Activity Manager into a more
independent existence. Making BroadcastQueue a top-level class and
regularizing its operation viz the primary Activity Manager operation
is the next step.

This change also updates the documentation to warn the user about which properties
require a call to mutate().

Users have requested the ability to sequence ViewPropertyAnimator
animations. it is not possible with AnimatorSet, which only takes objects
of type Animator (which VPA does not extend). But the AnimatorSet model
is not appropriate for VPA anyway, since it is not possible to set up
a VPA ahead of time to start later; it's just not the way that VPA is
intended to work.
Instead, there are now two new methods on VPA, onStart() and onEnd(). These
methods take a Runnable which is executed when the animation starts or ends.
These methods should allow other VPAs or other arbitrary code to execute at the
start or finish of any particular VPA animation, allowing simple sequencing
without the overhead of creating listeners and monitoring the cancelation status
of the VPA.
Additionally, this change adds a new method withLayer() which sets a hardware
layer on the VPA's target view for the duration of the animation. This
was already possible, but required writing boilerplate code to create a listener
and override the start/end methods to add and remove the layer. This utility method
makes this common use case much simpler and less error-prone.

When a view is becoming VISIBLE or INVISIBLE in a container with a
LayoutTransition, animations run to fade the view in and out and also
to run 'changing' animations on the view's other siblings. This logic
also cancels any running 'changin' animations to account for new ones
running.
However, in the specific case of INVISIBLE changes, there will be no
layout changes in the container - layout has already accounted for that
view (unlike in the case of GONE views); the visibility is just a matter of
drawing the view (or not). Therefore, we're canceling 'changing' animations
that should continue running and not replacing them with any other animations,
since new animations would only be started on layout chnages which are not
forthcoming.
One artifact seen from this bug is that the navigation bar buttons sometimes
disappear when changing orientation. This is because the menu button may
toggle between VISIBLE and INVISIBLE, causing animations on the other
buttons to get canceled, which leaves those views in a completely wrong
state.
The right thing to do is to avoid canceling in-process 'changing' animations
and to skip the logic of setting up new 'changing' animations which won't fire
anyway.
There is some minor API work in here because we did not previously have the
necessary information in LayoutTransition to know whether a view was being
hidden or shown to/from the INVISIBLE state.

Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

The comment of this field is also aggregated in the android.R.styleable#View
description. As a result, the @deprecated in the comment of this field also
applies to android.R.styleable#View which incorrectly appears deprecated.
This fixes the problem, although fadingEdge will no longer be marked as
deprecated in IDEs. I believe it is less important that to make View
deprecated.

o Add NdefRecord.toMimeType()
Maps the record to a MIME type
o Add NdefRecord.toUri()
Maps the record to a URI
o Add hidden NfcAdapter.dispatch()
Helps test the dispatch path.
o Modify createMime(), createUri() and createExternal():
Do not try and strictly follow RFC requirements for URI or MIME content
types. This just leads to heartbreak - the RFC requirements are too strict.
For example RFC1341 forbids the use of '.' in a MIME type, however this is in
common use in types such as "application/vnd.companyname". I think the best
approach is to only remove 'obvious' whitespace issues, and to convert
uppercase to lowercase as per Android guidelines.

1. The selector wheel was throwing an exception if a client requires that it
wraps its selector wheel if the number of values is less that the number
of values shown in the wheel. While wrapping makes no sense if the all
possible values are already shown, we should not throw an exception,
rather to ignore the request.

Added a new method ContentObserver.onChange(boolean, Uri) that
receives the changed content Uri. This can help applications make
better decisions about how to interpret a change notification.

Improved the documentation a little bit.
Fixed a bug in ContentService wherein if a ContentObserver was
passed as an argument and its deliverSelfNotifications() method
returned true, then notifyChange would tell all observers that
the change was a self-change even though it was only a self-change
from the perspective of the provided observer.
Deprecated ContentObservable.notifyChange since it is never
used and in general it shouldn't be because we want the notification
to be posted to the handler.
