Fixed a bug where we would lose the first touch point when swiping out of
the virtual key area.
Fixed a bug where we would not send an ACTION_MOVE event in cases where
individual pointers went down/up and the remaining pointers actually moved.
This is important since many applications do not handle pointer movements
during ACTION_POINTER_DOWN or ACTION_POINTER_UP. In the case of
ACTION_POINTER_UP the movement was completely lost since all pointers were
dispatched using their old location rather than the new location.
Improved motion event validation to check for duplicate pointer ids.
Added an input source constant that was missing from the NDK api but
defined in the framework api.
Added a timestamp when reporting added/removed devices in EventHub.

We now poke user activity twice: once upon dequeueing an event
for dispatch and then again just before we dispatch it. The second
poke is to compensate for the fact that it can take a few seconds to
identify the dispatch target (if the application is responding slowly)
but we want to keep the display from going to sleep for X amount of time
after the app gets a chance to actually receive the event. This mirrors
pre-Gingerbread behavior.
Removed some unnecessary code that filters user activity pokes when sending
events to KeyGuard. We don't need this because KeyGuard already tells the
power manager to disable user activity.

Added new key maps for external keyboards. These maps are intended to
be shared across devices by inheriting the "keyboards.mk" product
makefile as part of the device's product definition.
One of the trickier changes here was to unwind some code in
MetaKeyKeyListener that assumed that only the low 8 bits of the meta key
state were actually used. The new code abandons bitshifts in favor
of simple conditionals that are probably easier to read anyways.
The special meta key state constants used by MetaKeyKeyListener
are now (@hide) defined in KeyEvent now so as to make it clearer that they
share the same code space even if those codes are not valid for KeyEvents.
The EventHub now takes care of detecting the appropriate key layout
map and key character map when the device is added and sets system
properties accordingly. This avoids having duplicate code in
KeyCharacterMap to probe for the appropriate key character map
although the current probing mechanism has been preserved for legacy
reasons just in case.
Added support for tracking caps lock, num lock and scroll lock and
turning their corresponding LEDs on and off as needed.
The key character map format will need to be updated to correctly support
PC style external keyboard semantics related to modifier keys.
That will come in a later change so caps lock doesn't actually do
anything right now except turn the shiny LEDs on and off...
Added a list of symbolic key names to KeyEvent and improved the toString()
output for debug diagnosis. Having this list in a central place in the
framework also allows us to remove it from Monkey so there is one less
thing to maintain when we add new keycodes.

This change fixes several issues where events would be dropped in the
input dispatch pipeline in such a way that the dispatcher could not
accurately track the state of the input device.
Given more robust tracking, we can now also provide robust cancelation
of input events in cases where an application might otherwise become
out of sync with the event stream due to ANR, app switch, policy decisions,
or forced focus transitions.
Pruned some of the input dispatcher log output.
Moved the responsibility for calling intercept*BeforeQueueing into
the input dispatcher instead of the input reader and added support for
early interception of injected events for events coming from trusted
sources. This enables behaviors like injection of media keys while
the screen is off, haptic feedback of injected virtual keys, so injected
events become more "first class" in a way.

There is a new ANativeWindow::cancelBuffer() API that can be used to

returned to the list of availlable buffers. dequeue and cancel are not
mutually thread safe, they must be called from the same thread or
external synchronization must be used.

Redesigned the input dispatcher's ANR timeout mechanism so it is much
closer to Froyo's policy. ANR is only ever signalled if the dispatcher
is waiting on a window to finish processing its previous event(s) and
there is new pending input.
In the old code, we tracked the dispatch timeout separately for each
input channel. This was somewhat complicated and also resulted in the
situation where applications could ANR long after the user had pushed
them into the background.

As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).
Removed the dependence on specific constants from sys/poll.h such as
POLLIN. Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports. That should help make any future
under-the-hood implementation changes easier.
Fixed a couple of compiler warnings along the way.

all events log the buffer conserned and a timestamp in microseconds.
by default the logging is not enabled, to turn it on:
adb shell service call SurfaceFlinger 1006 i31 1
adb shell setprop debug.graphic_log 1
The effect is immediate in SurfaceFlinger, but applications need to be
restarted.

This change is essentially a rewrite of the main input dispatcher loop
with the target identification folded in. Since the input dispatcher now
has all of the window state, it can make better decisions about
when to ANR.
Added a .5 second deadline for processing app switch keys. This behavior
predates Gingerbread but had not previously been ported.
Fixed some timing inaccuracies in the ANR accounting that could cause
applications to ANR sooner than they should have.
Added a mechanism for tracking key and motion events that have been
dispatched to a window so that appropriate cancelation events can be
synthesized when recovering from ANR. This change helps to keep
applications in sync so they don't end up with stuck buttons upon
recovery from ANRs.
Added more comments to describe the tricky parts of PollLoop.

Added the MotionEvent.FLAG_WINDOW_IS_OBSCURED flag which is set by the
input manager whenever another visible window is partly or wholly obscured
the target of a touch event so that applications can filter touches

Added a "filterTouchesWhenObscured" attribute to View which can be used to
enable filtering of touches when the view's window is obscured.

On single-touch devices, pointer up/down is signalled by a BTN_TOUCH
key event. Previously we handled BTN_TOUCH immediately but some drivers
may produce the sequence BTN_TOUCH, ABS_X, ABS_Y, SYN_REPORT on pointer down
which caused us to emit a bad initial pointer down location.
Now we wait for SYN_REPORT before reporting the up or down.
On multi-touch devices, pointer up can be signalled by as little as
the sequence SYN_MT_REPORT, SYN_REPORT. This change ensures that we
handle this case.
Added support for reading ABS_MT_PRESSURE when available.
Corrected mapping of touchMajor/touchMinor on single touch devices.
Minor code cleanup.

Sometimes the wrong fd was accessed when the device was addressed
by device id.
The earlier implementation assumed that two arrays were in sync
but one of them was compacted when devices were removed. Instead
of that dependency the device now keeps track of it's file descriptor.
Change-Id: Ib0f320603aafb07ded354bc3687de9759c9068f2
Previously, the input dispatcher assumed that the input channel's
receive pipe file descriptor was a sufficiently unique identifier for
looking up input channels in its various tables. However, it can happen
that an input channel is disposed and then a new input channel is
immediately created that reuses the same file descriptor. Ordinarily
this is not a problem, however there is a small opportunity for a race
to arise in InputQueue.
When InputQueue receives an input event from the dispatcher, it
generates a finishedToken that encodes the channel's receive pipe fd,
and a sequence number. The finishedToken is used by the ViewRoot
as a handle for the event so that it can tell the InputQueue when
the event has finished being processed.
Here is the race:
1. InputQueue receives an input event, assigns a new finishedToken.
2. ViewRoot begins processing the input event.
3. During processing, ViewRoot unregisters the InputChannel.
4. A new InputChannel is created and is registered with the Input Queue.
This InputChannel happens to have the same receive pipe fd as
the one previously registered.
5. ViewRoot tells the InputQueue that it has finished processing the
input event, passing along the original finishedToken.
6. InputQueue throws an exception because the finishedToken's receive
pipe fd is registered but the sequence number is incorrect so it
assumes that the client has called finish spuriously.
The fix is to include a unique connection id within the finishedToken so
that the InputQueue can accurately confirm that the token belongs to
the currently registered InputChannel rather than to an old one that
happened to have the same receive pipe fd. When it notices this, it
ignores the spurious finish.
I've also made a couple of other small changes to avoid similar races
elsewhere.
This patch set also includes a fix to synthesize a finished signal
when the input channel is unregistered on the client side to
help keep the server and client in sync.
