1. Scrolling actions are crucial for enabling a gesture based
traversal of the UI and specifically scrollable containers
especially lists and anything backed by an adapter. Since
accessibility focus can land only attached views, it cannot
visit views for adapter items not shown on the screen.
Auto scrolling the list as a result of putting access focus
ot a list item does not work well since the user may get
trapped in a long list. Adding an accessibility node provider
to emit virtual views for one view before the first and one
after the last is complex and suffers the limitation of trapping
the user. Accessibility service need an explicit scroll actions
which may be performed upon an explicit user action. Hence,
the user is informed for the start/end of the visible part of
the list and he makes a deliberate choice to scroll. This will
benefit also people developing Braille devices since they can
scroll the content without telling the user to stop using the
Braille controller and take the device out of his pocket to scroll
and go back to the Braille controller.
NOTE: Without these action large portions of the screen will be
hard to access since users will have to touch and explore to
find and scroll the list.

Prior to this fix once dimming had been turned on it stayed at the
same layer and associated with the same window until it was turned
off. Now the DimAnimator layer is updated if either the window layer
changes or the dimming window changes.

Drawing in windows is suppressed during window animations, to make window
animations smoother. This means that drawing activities that the activity
requested are dropped on the floor. There is no call at the end of window
animations to tell the windows that they may now draw, which leaves the windows
and activities in an uncertain state, especially with respect to some of the
dirty flags that we use internally to know when we have requested (and satisfied)
invalidations on views.
The fix is to notice, on the WindowManager side, when we've finished window
animations and to schedule a traversal on the WindowManager, which will then send
out appropriate messages to the affected windows.

1. Previous fix to hide wallpaper at the same time the wallpaper target
was hidden was too aggressive. In the case where one wallpaper target
was replacing another we would lose the wallpaper for an instant.
2. Previous fix to keep from overwriting the moving window boundaries
was incomplete. The default values for the parent window were 0,0
which caused the lock window animation to translate down and to the
right. Defaulting the parent window boundaries to the full screen
and restoring it to the full screen after each animation fixes this.
Fixes bug 6472070.

1. Delegating activation gestures has several issues that we should
decide how to handle if possible before allowing an accessibility
service to take over them:
A) It is needed that every view than can be clicked or long pressed on
reacts to such as a response to calling performClick and performLongPress
which is not necessary true since the view may watch the touch
events and do its own click long click detection. As a result it may
be possible that there are view a user cannot interact with in
touch exploration mode but can if not in that mode.
B) Clicking or long pressing on a different location in a view may yield
different results, for example NumberPicker. Ideally such views have
to implement AccessibilityNodeProvide which provider handles correctly
the request for click long press on virtual nodes. Some apps however
just fire different hover accessibility events when the user is over
a specific semantic portion of the view but do not provide virtual
nodes. Hence, a user will not be able to interact with such semantic
regions but the system can achieve that by sending the click/long click
at the precise location in the view that was last touch explored.
2. Adding a flag on accessibility service info to request explore by touch
mode. There is no need to put the device in this mode if node of the currently
enabled accessibility services supports it. Now the problem is inverted and
the service has to explicitly state its capability.
3. Fixing a bug where includeImportantViews was ignored for automation
services.

This problem was introduced in I74df9c24. The intention of the
change was still let UiTestAutomationBridge see the
non-important views, but there were bugs in the implementation:
1. AccessibilityManagerService was not really updating
mIncludeNotImportantViews when mIsAutomation is true
2. Wrong constant is used to set the flag

If a fallback key is generated using a key plus a modifier,
then it's possible we might get a different fallback key
generated if the modifier has changed. PhoneWindowManager
needs to remember which fallback is last generated for a
given key code so that it can apply the same fallback action.
When generating cancellation events, it's important to have
preserved the policyFlags of the original event. Otherwise
we may not dispatch the cancellation properly. For example,
some actions are not performed if the POLICY_FLAG_TRUSTED
is not specified.
Remember the metaState associated with a key event so we can
include it when canceled.
Tell the policy when a fallback is being cancelled so that it
can clean up its state.
After a SEARCH shortcut is invoked, clear the flag indicating
that a shortcut is pending. This is to prevent SEARCH from
getting stuck down in the case where we might forget to send
the up. (Shouldn't happen anymore after the prior fixes.)

If the layout goes through more than one pass after detecting a window
movement but before animation begins then the later pass overwrites
the animation offsets. The incorrect values are large leading to an
animation starting location in the bottom right corner.

Qualify the test for wallpaper animation to exclude the dummy
animation. This keeps us from treating a dummy-animating wallpaper
as an exiting wallpaper and providing the wrong animation.

If there were apps already installed that were added in a later system
OTA, bad things would happen.
If the previously installed application is an older version, simply
delete the installed application. If the system app is older than the
previously installed one, mark it as a disabled system app and use the
previoulsy installed application.
Additionally, the application will now have the correct granted

Clean up related to new Vibration policy.
The vibrate behavior is now only derived from:
- presence of a vibrator on the device
- current ringer mode selected: NORMAL, VIBRATE or SILENT
If no vibrator is present the ringer mode can only be NORMAL or SILENT.
The control of ringer mode via volume keys when volume keys control the "master"
stream type (RING on phones, MUSIC on tablets) is as follows:
If a vibrator is present:
VOL- and volume equals 1: NORMAL => VIBRATE
VOL- and volume equals 0 and not continuous press: VIBRATE => SILENT
VOL+ and in SILENT mode: SILENT => VIBRATE
VOL+ and in VIBRATE mode: VIBRATE => NORMAL, volume = 1
If no vibrator is present:
VOL- and volume equals 0 and not continuous press: NORMAL => SILENT
VOL+ and in SILENT mode: SILENT => NORMAL, volume = 0
VIBRATE_ON and VIBRATE_IN_SILENT settings are not stored/retreived any more.
AudioService checks and corrects ringer mode and stream volumes if necessary when reading from
DB at boot time.
Also:
Added dump for stream volumes in AudioService.
Added device names missing in AudioSystem for USB accessory and USB device.
