79ac969d7a Add tap/drag touchpad gesture.
The mapper sends a DOWN when the finger is released then starts
a short timer.  If the finger is not pressed again before the timer
elapses, then the mapper sends an UP to complete the tap.  If the
finger is pressed again then the mapper starts sending MOVEs
as part of a drag.

Double/triple taps work as intended because we also start watching
for a new tap when the finger is pressed again.  If a new tap
occurs the old tap is also finished.  So each individual finger
short press/release cycle constitutes a distinct tap.

2352b978a3 Initial checkin of spot presentation for touchpad gestures.
Added a new PointerIcon API (hidden for now) for loading
pointer icons.

Fixed a starvation problem in the native Looper's sendMessage
implementation which caused new messages to be posted ahead
of old messages sent with sendMessageDelayed.

Redesigned the touch pad gestures to be defined in terms of
more fluid finger / spot movements.  The objective is to reinforce
the natural mapping between fingers and spots which means there
must not be any discontinuities in spot motion relative to
the fingers.

Removed the SpotController stub and folded its responsibilities
into PointerController.

5541de9ea3 Add a sprite controller.
Refactored PointerController to extract the surface management
code to a new component called a SpriteController so that it can
be used to move finger tracking spots around the screen as well.
The SpriteController is designed to fully decouple the client from
any latency introduced by surface transactions and drawing.
All sprite updates are performed asynchronously on the Looper using
a copy of the sprite state.

Added a stub SpotController implementation for touch pad UX.
It will be implemented in a subsequent patch.

Fixed a little bug in pointer orientation changes when entering
DISPLAY_ORIENTATION_90 the x offset was clobbered.

4e91a180be Coalesce input events that arrive faster than 333Hz.
Some drivers report individual finger updates one at a time
instead of all at once.  When 10 fingers are down, this can
cause the framework to have to handle 10 times as many events
each with 10 times as much data.  Applications like
PointerLocation would get significantly bogged down by all
of the redundant samples.

This change coalesces samples that are closely spaced in time,
before they are dispatched, as part of the motion event batching
protocol.

Increased the size of the InputChannel shared memory buffer so
that applications can catch up faster if they accumulate a
backlog of samples.

Added logging code to help measure input dispatch and drawing
latency issues in the view hierarchy.  See ViewDebug.DEBUG_LATENCY.

0029c66203 Add input filter mechanism for accessibility.
This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications.  At this time,
the mechanism is only intended to be used by the accessibility
system to implement built-in system-level accessibility affordances.

The accessibility input filter is currently just a stub.
It logs the input events receives and reinjects them unchanged,
except that it transforms KEYCODE_Q into KEYCODE_Z.

Currently, the accessibility input filter is installed whenever
accessibility is enabled.  We'll probably want to change that
so it only enables the input filter when a screen reader is
installed and we want touch exploration.

da3d5a91b6 Support chorded fallback keys.
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.

a032cc0086 Add MotionEvent.HOVER_ENTER and HOVER_EXIT.
The input dispatcher sends a HOVER_ENTER to a window before dispatching
it any HOVER_MOVE events.  For compatibility reasons, the window will
*also* receive the HOVER_MOVE.  When the pointer moves into a different
window or the pointer goes down or when events are canceled for some reason,
the input dispatcher sends a HOVER_EXIT to the previously hovered window.

The view hierarchy behavior is similar.  All views under the pointer
receive onHoverEvent with HOVER_ENTER followed by any number of HOVER_MOVE
events.  When the pointer leaves a view, the view receives HOVER_EXIT.
Similarly, if a parent view decides to capture hover by returning true
from onHoverEvent, the hovered descendants will receive HOVER_EXIT.

The default behavior of onHoverEvent is to update the view's hovered
state by calling setHovered(true/false).  Views can query their current
hovered state using isHovered().

For testing purposes, the hovered state is mapped to the pressed
drawable state.  This will change in a subsequent commit with the
introduction of a new hovered drawable state.

ace13b1786 Use touch pad gestures to manipulate the pointer.
1. Single finger tap performs a click.
2. Single finger movement moves the pointer (hovers).
3. Button press plus movement performs click or drag.
   While dragging, the pointer follows the finger that is moving
   fastest.  This is important if there are additional fingers
   down on the touch pad for the purpose of applying force
   to an integrated button underneath.
4. Two fingers near each other moving in the same direction
   are coalesced as a swipe gesture under the pointer.
5. Two or more fingers moving in arbitrary directions are
   transformed into touches in the vicinity of the pointer.
   This makes scale/zoom and rotate gestures possible.

Added a native VelocityTracker implementation to enable intelligent
switching of the active pointer during drags.

Associate each motion axis with the source from which it comes.
It is possible for multiple sources of the same device to define
the same axis.  This fixes new API that was introduced in MR1.
(Bug: 4066146)

Fixed a bug that might cause a segfault when using a trackball.

Only fade out the mouse pointer when touching the touch screen,
ignore other touch pads.

Changed the plural "sources" to "source" in several places in
the InputReader where we intend to refer to a particular source
rather than to a combination of sources.

Improved the batching code to support batching events from different
sources of the same device in parallel.  (Bug: 3391564)

Simplified the InputReader somewhat and removed support for a

We now assume that the touch device provides useful absolute axis
ranges for the X and Y axes since the alternative does not actually
make sense.

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.

support one button.)

58a2da843f Fix crashes caused by some input devices.
The touch screen sometimes reports more than 10 pointers even though that's
all we asked for.  When this happens, we start dropping events with more
than 10 pointers.  This confuses applications and causes them to crash.
Raised the limit to 16 pointers.
Bug: 3331247

The default behavior was to identify all touch devices as touch screens.
External devices that are plugged in are more likely to be touch pads
not attached to a screen.  Changed the default to be a touch pad
and renamed some internal constants to avoid confusion.

A certain mouse happens to also behave like a touch pad.  That caused
problems because we would see multiple concurrent traces of motion events
coming from the same input device so we would batch them up.
Added code to ensure that we don't batch events unless they come from
the same *source* in addition to coming from the same *device*.

Due to batching or misbehaving drivers, it's possible for the set of
pointer ids to be different from what we expect when it comes time to
split motion events across windows.  As a result, we can generate motion
events with 0 pointers.  When we try to deliver those events, we cause
an error in the InputTransport so we tear down the InputChannel and kill
the application.
Added code to check out assumption about pointer ids and drop the
event gracefully instead.

Patched up the tests to take into account the change in default behavior
for identifying touch screens and touch pads.
