...while listening to TTS example
This was a nice one. What was happening is that immediately upon
being created, the activity was starting another activity in a
different process. The second activity would never show, just
immediately exit. However the original activity had time to
pause and get into stopping itself before the second activity had
come back to the activity manager to say it was going away, resulting
in the activity manager asking the original activity to resume.
At this point the activity manager's state is that the second
activity is finishing and gone, and the original activity is
resumed. However in the app process the original activity is
still working on stopping itself, and it eventually completes
this and tells the activity manager. The activity manager now
changes its state to STOPPED, even though it is actually resumed
and that is the last thing it told it to be, and it is now
proceeding to set itself in that state.
This would result later in the activity manager sending an
unnecessary state change to the application. In the case of
the screen here, we next do a rotation change, the activity
manager thinks the current state is STOPPED not RESUMED, so it
tells the application to relaunch the activity in a new config
but not in the resumed state. Now it does the whole "start a
new temporary activity" thing again, at which point it tries
to pause the original activity again, and we have an unbalanced
onPause() call to the app and it falls over.

1. Now the views considered during the accessibility focus search
are the ones that would get accessibility focus when thovered
over. This way the user will get the same items i.e. feedback
if he touch explores the screen and uses focus traversal. This
is imperative for a good user experience.
2. Updated which focusables are considered when searching for access
focus in ViewGroup. Generally accessibility focus ignores focus
before/after descendants.
3. Implemented focus search strategy in AbsListView that will traverse
the items of the current list (and the stuff withing one item
before moving to the next) before continuing the search if
forward and backward accessibility focus direction.
4. View focus search stops at root namespace. This is not the right
way to prevent some stuff that is not supposed to get a focus in
a container for a specific state. Actually the addFocusables
for that container has to be overriden. Further this approach
leads to focus getting stuck. The accessibility focus ignores
root names space since we want to traverse the entire screen.
5. Fixed an bug in AccessibilityInteractionController which was not
starting to search from the root of a virtual node tree.
6. Fixed a couple of bugs in FocusFinder where it was possible to
get index out of bounds exception if the focusables list is empty.

Whenever a stream type is muted, the progress bar in volume panel
is at 0.
If a stream is muted by ringer mode and does not control ringer mode,
the progress bar is disabled.
Pressing VOL- when in vibrate or silent mode resets the last audible
volume of ringtone stream (music strem on tablets) to 0.
VolumePanel implementation:
- Always prefer AudioManager APIs over AudioService APIs when available on both.
- Do not use AudioManager.shouldVibrate() (deprecated).

Bug 6404882.
The supplied code in this bug sets up a table with 2 columns and then
tries to add a component in column 5. Earlier attempts to fix this
by 'doing what the user meeant' had unwanted side-effects. This CL is
intended to defend against all ways to register invalid LayoutParams
and throw IllegalArgumentExcpetion when any column index falls outside the
range [0 .. N] where N is the number of columns. It also includes the
symmetrical check for rows.

Simplify text selection to use left/right rather than
base/extent. In combination with webkit change, this
fixes RTL selection. The handle directions are properly-
facing when the text direction is the same for both
sides of selection.

1. The initial design was to have some accessibility gestures
being handled by the system if the gesture handling access
service does not consume the gesture. However, we are not
sure what a good default is and once we add a default handler
we cannot remove it since people may rely on it. Thus, we
take the simples approach and let the accessibility service
handle the gestures. If no gestures are handled the system
will work in explore by touch as before.

This refactoring sets the stage for a follow-on change that
will make use additional functions of the power HAL.
Moved functionality from android.os.Power into PowerManagerService.
None of these functions make sense being called outside of the
system server. Moving them to the PowerManagerService makes it
easier to ensure that the power HAL is initialized exactly once.
Similarly, moved ShutdownThread out of the policy package and into
the services package where it can tie into the PowerManagerService
as needed.

1. Fixed errors in the accessibility node cache.
A. The cache was not catching the case when the current window changes as a
result the user touch exploring it. As a result the cache had nodes from
more that one window but the node ids are not unique thus causing a mess.
B. The node info tree was prefetched regardless if a prefetched node is root
name space (i.e. view ids - not accessibility ids - are namespaced) while
the prefetched nodes were taking this into account. As a result there can
get disconnected subtrees in the cache.
C. When an event for a property change such as focus was received the cache
we were removing the source node. As a result there may be disconnected nodes.
D. When a node was added to the cache and an older version exists there was
no check if it will point to the same children and parent. As a result if
the state of the node has fewer children the subtrees rooted at the no
longer present children will stay disconnected in the cache.
E. When a node got accessibility or input focus the old one in the cache was
not removed. As a result you may have a state with more than one access
or input focus.
2. Added integrity check enabled only on user builds when a specific flag is set
for the cache which checks whether:
A. All nodes are from the same window.
B. All nodes are connected.
C. There are no duplicates.
D. There is only one input focus.
E. There is only one accessibility focus.
3. The reported accessibility node info tree was stopping at the root namespace
boundary which is not correct. The reported tree has to reflect everything
on the screen that the user can see such a workspace with widgets. The root
namespace is added to avoid clash of view id but the accessibility ids are
unique no matter if the view is inflated from a remote view.
4. Added calls to notify the accessibility layer when a preoprty that is interesting
for accessibiliy has changed.

To improve performance, preventively cut the the into display
list of 3-10 lines of text. Further updates to small parts of
the text (such as adding an underline on a word) will only
invalidate and redraw the affected sub display list.
DLs are aligned with paragraphs, just like they will be during
text edition.
