f15a83f581 SurfaceFlinger: add a crop to the layer state
This change adds a crop rectangle specified in window coordinates to the layer
state.  The all window pixels outside this crop rectangle are treated as though
they were fully transparent.  This change also adds the plumbing necessary for
WindowManager to set that crop.

a18829ab23 Accurately track the sequence numbers of batched events.
Instead of sending finished signals immediately when appending to
a batch, record the chain of sequence numbers that were part of
the batch and then send finished signals all at once when done.
This change helps the dispatcher keep track of the true state
of the application and can improve ANR detection slightly.

f0490c94d0 Implement batching of input events on the consumer side.
To support this feature, the input dispatcher now allows input
events to be acknowledged out-of-order.  As a result, the
consumer can choose to defer handling an input event from one
device (because it is building a big batch) while continuing
to handle input events from other devices.

The InputEventReceiver now sends a notification when a batch
is pending.  The ViewRoot handles this notification by scheduling
a draw on the next sync.  When the draw happens, the InputEventReceiver
is instructed to consume all pending batched input events, the
input event queue is fully processed (as much as possible),
and then the ViewRoot performs traversals as usual.

With these changes in place, the input dispatch latency is
consistently less than one frame as long as the application itself
isn't stalled.  Input events are delivered to the application
as soon as possible and are handled as soon as possible.  In practice,
it is no longer possible for an application to build up a huge
backlog of touch events.

This is part of a series of changes to improve input system pipelining.

9ee44c8f94 Fix application launch shortcuts.

instead of hardcoding package and class names for all apps.

Added a set of Intent categories for typical applications on the

Added support for some of the HID application launch usages to
reduce reliance on quick launch for special purpose keys.  Some
keyboard vendors have hardcoded launch keys that synthesize
"Search + X" type key combos.  The goal is to encourage them
to stop doing this by implementing more of HID.

73aaf0d8d2 Velocity Tracker II: The Revenge of Velocity Tracker
Bug: 5265529

Rewrote the velocity tracker to fit a polynomial curve
to pointer movements using least squares linear regression.
The velocity is simply the first derivative of this polynomial.

Clients can also obtain an Estimator that describes the
complete terms of the estimating polynomial including
the coefficient of determination which provides a measure
of the quality of the fit (confidence).

Enhanced PointerLocation to display the movement curve predicted
by the estimator in addition to the velocity vector.

By default, the algorithm computes a 2nd degree (quadratic)
polynomial based on a 100ms recent history horizon.

ecc7adef2e Input system bug fixes, particularly for stylus.
Bug: 5049148

Finished stylus support, including support for indirect stylus
and mouse tools.

Added TILT axis.  When stylus tilt X/Y is available, it is transformed
into an orientation and tilt inclination which is a more convenient
representation and a simpler extension to the exiting API.

Touch devices now only report touch data using a single input
source.  Previously touch devices in pointer mode would report
both absolute touch pad data and cooked pointer gestures.
Now we just pick one.  The touch device switches modes as needed
when the focused application enables/disables pointer gestures.
This change greatly simplifies the code and reduces the load
on the input dispatcher.

Fixed an incorrect assumption that the value of ABS_(MT_)DISTANCE
would be zero whenever the stylus was in direct contact.  It appears
that the correct way to determine whether the stylus is in direct
contact (rather than hovering) is by checking for a non-zero
reported pressure.

Added code to read the initial state of tool buttons and axis values
when the input devices are initialized or reset.  This fixes
problems where the input mapper state might have the wrong initial
state.

Moved responsibility for cancelling pending inputs (keys down,
touches, etc.) to the InputDispatcher by sending it a device reset
notification.  This frees the InputReader from having to synthesize
events during reset, which was cumbersome and somewhat brittle
to begin with.

Consolidated more of the common accumulator logic from
SingleTouchInputMapper and MultiTouchInputMapper into
TouchInputMapper.

Improved the PointerLocation output.

5873ce46ad Refactor input reader to add stylus support.
Bug: 5064702

Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher.  The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world.  The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.

Consolidated all of the InputReader locks into one simple global
Mutex.  The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher.  To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.

Added tests for new stylus features such as buttons, tool types,
and hovering.

Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.

Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN.  Oops.

Changed PointerCoords so it no longer stores useless zero
axis values.  Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.

Added dispatch of stylus hover events.

Added support for distance and tool types.

acb7b5dfc8 Adding SurfaceEncoder for encoding FilterFrames
Adding SurfaceEncoder which can be used to encode
custom frame data. In a sense, it is reverse
of what SurfaceTexture does.

SurfaceEncoder takes in frames from a native window and
passes them to an encoder, thus acting like a MediaSource.
It uses GRAlloc buffers underneath for passing data.
The client side sets the geometry, format in the beginning,
which cannot be changed while the recording is going on.

Currently, there is no common pixel format that both
GRAlloc and HAL understand.
Also, the encoder cannot encode using the data from the GRAlloc
buffers.

The SurfaceEncoder_test examines mainly the buffer passage
since true encoding cannot be done at this point.
SimpleDummyRecorder 'reads' the frames in the same thread
as the start(), whereas DummyRecorder 'reads' in a separate
thread much like the MPEG4Writer. The test with DummyRecorder
is much closer to the real encoding implementation.

c5982b7bee Improve VelocityTracker numerical stability. (DO NOT MERGE)
Replaced VelocityTracker with a faster and more accurate
native implementation.  This avoids the duplicate maintenance
overhead of having two implementations.

The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation.  This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.

The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.

The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces.  The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

247da72a5b Use touch pad gestures to manipulate the pointer. (DO NOT MERGE)
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.

e959ed2533 Add initial API for stylus and mouse buttons.
Added the concept of pointer properties in a MotionEvent.
This is currently used to track the pointer tool type to enable
applications to distinguish finger touches from a stylus.

Button states are also reported to application as part of touch events.

There are no new actions for detecting changes in button states.
The application should instead query the button state from the
MotionEvent and take appropriate action as needed.

A good time to check the button state is on ACTION_DOWN.

As a side-effect, applications that do not support multiple buttons
will treat primary, secondary and tertiary buttons identically
for all touch events.

The back button on the mouse is mapped to KEYCODE_BACK
and the forward button is mapped to KEYCODE_FORWARD.

Added basic plumbing for the secondary mouse button to invoke
the context menu, particularly in lists.

Added clamp and split methods on MotionEvent to take care of
common filtering operations so we don't have them scattered
in multiple places across the framework.

16fe3c2c1f Better compat mode part one: start scaling windows.
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.

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.

Eino-Ville Talvala
1d01a12e71 Add support for timestamps into SurfaceTexture.
API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().

Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp().  For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

Jeff Brown
1593354388 Improve VelocityTracker numerical stability.
Replaced VelocityTracker with a faster and more accurate
native implementation.  This avoids the duplicate maintenance
overhead of having two implementations.

The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation.  This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.

The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.

The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces.  The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

fa773aa745 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.

eb8b9d8a22 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.

The ShortcutManager used to only receive the key code of the key event
that triggered the shortcut.  This change now provides the shortcut
manager with the whole key event so it can look up the associated
character using the correct key character map.

To make this more efficient, added a mechanism for recycling
key events.  At the moment it is only used by key events owned by the
system process, since clients of the existing API (such as Views)
might continue to hold on to key events after dispatch has finished so
they would break if the key event were recycled by the framework.

a3477c862a Added support for full PC-style keyboards.
BREAKING CHANGE: Redesigned the key character map format to
accomodate full keyboards with more comprehensive suite of modifiers.
Old key character maps will not work anymore and must be updated.
The new format is plain text only and it not compiled to a binary
file (so the "kcm" tool will be removed in a subsequent check-in).

Added FULL keyboard type to support full PC-style keyboards.

Added SPECIAL_FUNCTION keyboard type to support special function
keypads that do not have any printable keys suitable for typing
and only have keys like HOME and POWER

Added a special VIRTUAL_KEYBOARD device id convention that maps
to a virtual keyboard with a fixed known layout.  This is designed
to work around issues injecting input events on devices whose
built-in keyboard does not have a useful key character map (ie.
when the built-in keyboard is a special function keyboard only.)

Modified several places where events were being synthesized
to use the virtual keyboard.

Removed support for the "qwerty" default layout.
The new default layout is "Generic".  For the most part "qwerty"
was being used as a backstop in case the built-in keyboard did
not have a key character map (probably because it was a special
function keypad) and the framework needed to be able to inject
key events anyways.  The latter issue is resolved by using the
special VIRTUAL_KEYBOARD device instead of BUILT_IN_KEYBOARD.

Added the concept of a key modifier behavior so that
MetaKeyKeyListener can distinguish between keyboards that use
chorded vs. toggled modifiers.

Wrote more robust key layout and key character map parsers
to enable support for new keyboard features and user installable
key maps.

Fixed a bug in InputReader generating key ups when keys
are released out of sequence.

Updated tons of documentation.

Currently QwertyKeyListener is being used for full keyboards
with autotext and capitalization disabled.  This mostly works
but causes some problems with character pickers, etc.
These issues will be resolved in subsequent changes.

8149991234 Tell system server whether the app handled input events.
Refactored ViewRoot, NativeActivity and related classes to tell the
dispatcher whether an input event was actually handled by the application.

This will be used to move more of the global default key processing
into the system server instead of the application.

71484f2f76 Framebuffer: Support variable number of framebuffers in the UI
This change defines a macro NUM_FRAME_BUFFERS to set
the desired number of framebuffers to be used by the UI,
instead of hard-coding 2 framebuffers.

Aditional logic has been  added to handle the initialization
and destruction of NUM_FRAME_BUFFERS buffers.

fef5b04203 Drop all dispatcher state when dispatcher is disabled.
This patch makes the dispatcher drop all of its state when it is
disabled (when the screen turns off).  This ensures that the dispatcher
does not get stuck thinking a pointer is still down if the screen
turned off while the user was touching the display (such as a fat touch
while hitting the power button).

3c3cc62e24 Add unit tests for native input and fix bugs identified.
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.
