In our current environment with very many translations, this can
save a lot of RAM -- for example over 200K in Gmail just by sorting
the strings in the Gmail .apk (not the framework).
Also add a new aapt command to print the contents of the resource
table string pool.

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.

These markers will be used to group the GL commands by View in the
OpenGL ES debugging tool. This will help correlate individual GL
calls to higher level components like Views.

Because the NetworkInfo included in CONNECTIVITY_ACTION broadcast
extra does not reflect the state applicable to the calling UID, and
the last sticky broadcast may have stale state, transition to calling
ConnectivityManager.getActiveNetworkInfo() directly.

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.

Bug 5556478
Launcher pre-populates its all apps and widget pages with their
content, which includes text. The layout calls some onMeasure methods
that trigger TextView's registerForPreDraw(), which in turns adds a
listener in the ViewTreeObserver.
However, some of these pages may never be actually displayed, leaving
the listeners in the list since onDraw() is never called.
As a result, every frame displayed by launcher is slowned down by this
array copy of 6-18 listeners.
The problem is not Launcher specific since other applications may use
a similar caching mechanism.
The solution is to unsubscribe the listener in onPreDraw.
The drawback is that several successive calls to registerForPreDraw() will
add/remove the some listener object. However, these calls are rare and are
relatively cheap since we're just adding the object in and out of an
ArrayList which should not need to change its size.

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.

Previously, we'd pass in a scale factor (based on whether the app was
being scaled by the compatibility mode) to Animation.getTransformation().
This scales the pivot point of the animation based on thes cale factor.
However, the pivot points were already using information that took the
compatibility mode scale into account. For example, using ABSOLUTE and basing
pixel values on the width/height of the view would give you values relative to the
width/height of the view (pre-scaled). Using RELATIVE_TO_* would use percentages
for the pivot point, again taking the scaling of the view into account. So scaling
the pivot point added in another scale on top of that already being applied.
The net effect was to scale the pivot point in cases where it should not be scale.
For example, setting a pivot point to half-way (.5 and RELATVE_TO_SELF) would
end up with an animation that would pivot around the bottom/right of the view.
The fix is to simply remove the scale factor being passed in; we've already accounted
for it in the pivot point, so we shouldn't concatenate it into the transform
calculated by the animation.

The framework tries to have a focused view all the time. For
that purpose when a view's focus is cleared the focus is given
to the first focusable found from the top. The implementation
of this behavior was causing the following issues:
1. If the fist focusable View tries to clear its focus it
was getting focus but the onFocusChange callbacks were not
properly invoked. Specifically, the onFocusChange for
gaining focus was called first and then the same
callback for clearing focus. Note that the callback
for clearing focus is called when the View is already
focused. Also note that at the end the View did not
clear its focus, hence no focus change callbacks
should be invoked.
2. If not the first focusable View tries to clear focus,
the focus is given to another one but the callback
for getting focus was called before the one for clearing,
so client code may be mislead that there is more than
one focused view at a time.
3. (Nit) The implementaion of clearFocus and unFocus in ViewGroup
was calling the super implementaion when there is a
focused child. Since there could be only one focused View,
having a focused child means that the group is not focused
and the call to the super implementation is not needed.
4. Added unit tests that verify the correct behavior, i.e.
the focus of the first focused view cannot be cleared
which means that no focus change callbacks are invoked.
The callbacks should be called in expected order.
Now the view focus clear precedes the view focus gain
callback. However, in between is invoked the global
focus change callback with the correct values. We may
want to call that one after the View callbacks. If
needed we can revisit this.
