This will eventually be replaced by something else, probably
in Configuration, that allows the WM to tell everyone
(including the status bar) whether there exist hardware
home/back/etc. keys.

Views requesting lights out mode will cause the navbar to
disappear (this is useful for viewing videos/photos/etc
using every pixel of the screen).
But there's a catch: any user activity at all will cause the
lights to come back on and the navbar to return.

First step of improving app screen size compatibility mode. When
running in compat mode, an application's windows are scaled up on
the screen rather than being small with 1:1 pixels.
Currently we scale the application to fill the entire screen, so
don't use an even pixel scaling. Though this may have some
negative impact on the appearance (it looks okay to me), it has a
big benefit of allowing us to now treat these apps as normal
full-screens apps and do the normal transition animations as you
move in and out and around in them.
This introduces fun stuff in the input system to take care of
modifying pointer coordinates to account for the app window
surface scaling. The input dispatcher is told about the scale
that is being applied to each window and, when there is one,
adjusts pointer events appropriately as they are being sent
to the transport.
Also modified is CompatibilityInfo, which has been greatly
simplified to not be so insane and incomprehendible. It is
now simple -- when constructed it determines if the given app
is compatible with the current screen size and density, and
that is that.
There are new APIs on ActivityManagerService to put applications
that we would traditionally consider compatible with larger screens
in compatibility mode. This is the start of a facility to have
a UI affordance for a user to switch apps in and out of
compatibility.
To test switching of modes, there is a new variation of the "am"
command to do this: am screen-compat [on|off] [package]
This mode switching has the fundamentals of restarting activities
when it is changed, though the state still needs to be persisted
and the overall mode switch cleaned up.
For the few small apps I have tested, things mostly seem to be
working well. I know of one problem with the text selection
handles being drawn at the wrong position because at some point
the window offset is being scaled incorrectly. There are
probably other similar issues around the interaction between
two windows because the different window coordinate spaces are
done in a hacky way instead of being formally integrated into
the window manager layout process.

Through invalidating panel menus and action bar initialization it was
possible for instance state restoration to throw out a new menu
already in use. Invalidate the menu if it already exists instead. The
saved instance state will be applied later if a relevant panel menu is
shown.

Apply (or extend) the theme Theme.Holo.SplitActionBarWhenNarrow or
Theme.Holo.Light.SplitActionBarWhenNarrow to enable splitting the
action bar across both the top and bottom of the screen. This places
the action menu along the bottom, leaving more room at the top for
titles, navigation, and custom views and more room at the bottom for
menu items.
TODO: Refine layout of the action menu when placed at the bottom of
the screen. Make action modes split as well.

In Honeycomb we introduced navigation controls in the status
bar, for xlarge devices without physical buttons. What about
phones? The status bar is pretty cramped already, and
besides, it's at the top of the display most of the time,
not at the bottom where your thumb is likely to be.
Enter the navigation bar. It's a new window type that
appears atop almost everything (including the keyguard); the
window manager subtracts its rectangle from the default
visible rectangle of other windows (including the status bar
and notification shade).
However, it behaves (on phones) like the status bar in that
applications that request fullscreen windows can get access
to those pixels. Well, almost; they need cooperation from
the navigation bar implementation to make the navbar
disappear, just like the status bar.
The current SystemUI implementation of the navigation bar on
phones is still rough, but it has the basics:
+ back, home, and menu keys (NB: we're showing menu all the
time right now because checking the api level of the
package owning the top window is currently a poor
indicator of whether the app requires the menu key)
+ it tries to stick to the same physical end of the device,
regardless of device orientation (on a phone, this is
the strip of land closest to the microphone)

Not yet working, so turned off.
Also fix a bug where the display size configuration became inconsistent
after a configuration change -- we now figure out everything about the
display size when computing a new configuration.
In the old world, MenuBuilder and MenuItemImpl were responsible for
generating views for any presentation of a menu. MenuBuilder needed to
know any types and resources involved, and the implied caching
semantics did not work well for menus presented within AdapterViews.
In the new world, the MenuPresenter interface takes over the
responsibility of generating views or adapters for menu
items. MenuBuilder/MenuItemImpl still provide extra metadata tracking
used by these presenters. Mutiple presenters may be active for a
single menu at a time. All of this remains internal framework
implementation details.
BaseMenuPresenter provides a simple base for presenters that treats
the host MenuView more like an AdapterView. This allows for less
rebuilding of views when items are added/removed.
Callbacks have been restructured. Calls that relate to the menu itself
are still handled by MenuBuilder.Callback, but calls related to a
specific presentation of a menu are handled by MenuPresenter.Callback
objects attached to a MenuPresenter.
Also add API to programmatically set divider options for LinearLayout
and hidden API so that ActionBarView can have finer-grained control
over divider placement.

Alt-TAB should have different semantics from the APP_SWITCH key
or long-press on HOME. Accordingly, remove the fallback action
for Alt-TAB and initiate the task switching behavior directly
in the policy.
Modified RecentApplicationsDialog to be more precise about the
initial modifiers that it considers to be holding the dialog.
The dialog is now dismissed by a second press on the APP_SWITCH
key or by a second long press on HOME.

Also be more careful about canceling fallback keys during focus
transitions, when the application handles the key, or when the
policy decides to do something different.
Fixed a crash due to JNI CallObjectMethod returning an undefined
value (not null) when an exception is thrown.
Fixed a crash due to the policy trying to create a Dialog for
recent apps on the dispatcher thread. It should happen on the
policy's Looper instead.

Added some plumbing to enable the policy to intercept motion
events when the screen is off to handle wakeup if needed.
Added a basic concept of an external device to limit the scope
of the wakeup policy to external devices only. The wakeup policy
for internal devices should be based on explicit rules such as
policy flags in key layout files.
Moved isTouchEvent to native.
Ensure the dispatcher sends the right event type to userActivity
for non-touch pointer events like HOVER_MOVE and SCROLL.

DigitalClock could sometimes leak when the keylock was recreated.
This happened because onDetachedFromWindow() was called BEFORE
onAttachedFromWindow().
This is the flow that causes the memory leak:
1) The LockPatternKeyGuardView is created and added. This will start
a loop dispatching onAttachedToWindow() to all views involved.
2) PatternUnlockScreen.onAttachedToWindow() is called
3) If the configuration has changed since creation, recreateMe() in
LockPatternKeyguardView.java is called.
4) recreateScreens() is called
5) PatternUnlockScreen is removed (to be re-added later) in
LockPatternKeyguardView.recreateUnlockScreen()
6) Since DigitalClock is a part of PatternUnlockScreen, its
onDetachedFromWindow() will be called.
7) The loop started in 1) will continue to dispatch
onAttachedToWindow() - and will eventually call
DigitalClock.onAttachedToWindow()
8) DigitalClock.onAttachedToWindow() registers a receiver that is
normally unregistered in onDetachedFromWindow(). But since
onDetachedFromWindow was already called in 6), it will not be called
again.
9) The receiver has leaked, and it has a reference to DigitalClock,
so that will leak as well, together with its parents e.g.
PatternUnlockScreen and LockPatternKeyguardView
The fix is to wait with the recreation of the screens (in 4) until
the loop (in 1) is finished. This is done by posting this as an event
instead of calling recreateScreens() immediately.
It is possible that this a fix for the root cause mentioned in
"Fix 3106227: use WeakReferences for receivers in DigitalClock class"

Dispatch ACTION_HOVER_MOVE and ACTION_SCROLL through the View
hierarchy as onGenericTouchEvent. Pointer events dispatched
this way are delivered to the view under the pointer. Non-pointer
events continue to be delivered to the focused view.
Added scroll wheel support to AbsListView, ScrollView,
HorizontalScrollView and WebView. Shift+VSCROLL is translated
to HSCROLL as appropriate.
Added logging of new pointer events in PointerLocationView.
Fixed a problem in EventHub when a USB device is removed that
resulted in a long stream of ENODEV errors being logged until INotify
noticed the device was gone.
Note that the new events are not supported by wallpapers at this time
because the wallpaper engine only delivers touch events.
Make all mouse buttons behave identically. (Effectively we only
support one button.)

Only initiate fallback key handling if the first key down was
not handled and there is no other fallback key already in progress.
This prevents spurious fallbacks from being generated when
applications handle the initial down but not repeated downs or the up.

E.g. if an app is sensorLandscape and the device rotation is
locked to landscape, the activity should not be allowed to
flip to seascape even if the device is inverted.
If the rotation is locked 90° from the activity's
supported orientations, we must override the lock as before,
but we now suppress the sensor input (confining the activity
to one of its two orientations). This best preserves the
spirit of the rotation lock while still allowing the
activity to run in a supported configuration.
