The objective in this listener is to be more careful about the
signal processing to prevent spurious orientation changes
and to make all of the tweakable factors physically meaningful.
The calibration is defined in terms of time constants and
does not assume a particular discrete sampling rate. This is
useful because it allows us to change the accelerometer sampling
interval if desired without having to change the calibration.
Moreover, the accelerometer sampling interval can vary +/- 20ms
from one sample to the next even in normal circumstances.
Proposed orientation changes are weighted by confidence factors
that vary exponentially in relation to how close the device
is to the ideal orientation change posture (screen is vertical,
angle is exactly at the midpoint of the orientation quadrant,
and no external acceleration beside gravity). When not in an ideal
posture, the device takes proportionally longer to settle into a
new orientation state.
Added a little tool to plot the log output of the
WindowOrientationListener. Check the README for more information
about how to use it.

is done in touch event. textIsEditable is now checked too.

1. Remove mDeferMultiTouch in WebView, it was for testing only but
we don't need it now since we always pass MultiTouch to WebKit.
2. Remove the use of mDeferMultiTouch in DRT tests.
3. Correct the index of getX(Y) for the second touch point in the
debug string of MotionEvent.

Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

1. Views may setSystemUiVisibility() to recommend that
the system chrome (status bar or other UI) show or hide
itself. (This functionality was previously available only
via the FLAG_FULLSCREEN window flag for some SystemUI
implementations.)
2. Views may register a OnSystemUiVisibilityChangedListener
on a view, and find out when the system UI actually
appears or disappears, allowing apps to coordinate the
appearance of their own UI if desired.

The activity manager was not performing the layout pass on the new window,
because its app token was still hidden, because the activity manager / window
manager were still waiting for it to be ready to show.
Just ignore whether the app token is hidden for this case.
Also fixes some problems with animations, and tweaks the ViewConfiguration
values for xlarge screens.

On touch up, View would move itself to the pressed state if it
hadn't already shown as pressed. However, it did this *after*
scheduling the message to deliver the onClick(). Thus if the
app took a little too long to execute inside of onClick(), the
invalidate to draw the highlight state would be executed right
before the following message to remove the highlight state,
causing it to basically not be shown.
This change just does the invalidate before scheduling the
onClick, so we can be sure it gets done first.

Fixes bug 3362502
The underlying cause was that the DragEvent.obtain() variant which
clones an existing event was failing to copy the local state field.
This change also moves the logic for inserting the local state object
into DragEvents about to be dispatched from the Binder incall thread
into the main-thread code sequence. This is to eliminate any potential
SMP memory coherency issues around drag start vs incoming events
needing to refer to the local state object.

In particular, if a new window was created out from under the drag,
the drag-move event dispatch logic would wind up blithly assuming
that it would find a valid touch-dispatchable window under the
finger. When this was untrue, it would NPE, but the NPE was caught
and discarded safely by higher-level guard code.
With this change, we now avoid the NPE entirely and report the
spurious condition as part of the debugging log stream.
(Also add the local-state object to DragEvent.toString()'s output.)

Bug 3347962
Root cause of this problem: if the adapter's content gets updated by a backgroung
thread, the PopupDataSetObserver will call showDropDown which will popup the
list.
Added a flag to make this call show the popup iif it is already visible.
This relayout is needed to clear the mDataChanged flag set when the content was
modified and which otherwise prevents touch events on the result list.
ArrayAdapter didn't use its lock to protect access to mObject.
-------------------------------------------------
However, the study of the this race conditions revealed an other bug:
Updated adapter's content is not displayed in filtered AutoCompleteTextView

1. ViewGroups being removed from the layout during a drag would wind up
crashing the app with an NPE at drag-ended time, due to blind dereference
of now-cleared object pointers.
2. Passing a 'null' ClipData to startDrag() would crash the system
process with an NPE. Should this even be valid? I'm inclined to say
yes, though it means that apps will need to guard against it.

Don't dismiss by default when tapping outside, even for AlertDialog.
If AlertDialog doesn't have any buttons, tapping outside will dismiss it.
Applications can make their own dialogs (or activities looking like
dialogs) can use the existing and new APIs to control this behavior
themselves so that it does the right thing.
