The new implementation more accurately tracks the velocity
of flings and takes care to avoid obvious discontinuities.
The main goal is for a fling to appear to be a linear
extension of the movement already in progress. The minimum
fling velocity is set to ensure that flings appear to be
fairly smooth despite being discretized.
Use sequences of repeated key events instead of individual
down/up events to represent continuous motions in one
direction which can be helpful for stopping flings at boundaries
such as when flinging the cursor position within a text view.
Compute the movement thresholds based on the physical
size of the touch pad, if known. If not known, we assume a
nominal size.
Support stopping flings with a tap just like we do for
normal touch events elsewhere in the framework.
Moved the detection of ASSIST swipes into the InputReader
where it belongs. These swipes must be detected globally
to ensure consistent behavior across the all applications.
Added a custom protocol in EventHub to enable input device
drivers to override the timestamp of the following events
in a packet. This change enables input device drivers
that have a better idea of when an input event was actually
generated to pass this information to the input system.
Particularly useful with uinput.

Ensure that all callbacks into the window manager policy occur
on the input dispatcher thread in the right place. This fixes
a potential deadlock that may occur if the window manager
unregisters an input channel while holding its own lock.
The change is simply to defer running asynchronous commands
(usually callbacks into the policy) until the next iteration
of the dispatch looper thread.

This can happen due to a race when the input device is
opened or if the kernel happens to be missing the required
Android patches to set the timestamp correctly.

The input system needs to know about the window that has
focus, even if it is on a secondary display. So now we
send it the list of all windows and indicate which display
they are on. We filter the list of windows as necessary
when delivering touch events.
To keep things simple, monitor input channels and input
filters are not supported except on the main display.
We also do not pass the display id to applications; it is
only used inside the input system for now.
Properly scale touch coordinates based on the viewport.
This will be needed to ensure that touch works on external
display as well as when the internal display is being used
to simulate a different resolution.

The window manager is no longer responsible for telling the

Cleaned up the implementation of Surface and SurfaceSession
to use more consistent naming and structure.
Added JNI for all of the new surface flinger display API calls.
Enforced the requirement that all Surfaces created by
the window manager be named.
Updated the display manager service to use the new methods.

Some touch device drivers report the range of
ABS_MT_ORIENTATION as [0,1]. The Linux multitouch protocol
spec says that the 0 value should always be considered vertical.
Add a new 'box' calibration mode for size to handle the case
where width and height are being provided. The 'diameter'
calibration mode is inadequate because it drops one of these
components.

Some ANR bugs are very difficult to localize because by the time
the bug report has been captured, the relevant information is
gone. Work around this by capturing a log of the input dispatcher's
state at the exact time of the ANR before anything has changed
and include this information in the bug report.
Also fixed a nit related to some format strings that had
improper field widths specified.

When an ANR occurs, log the associated reason.
When an event takes too long to process (currently more than 2 seconds)
log basic information about the event including how long it actually
took.
Dump the contents of the inbound, outbound and wait queues as part

Prevents ANR on hover or scroll events.
Prevents ANR in the case where one finger touches a window which
is subsequently removed then a second finger comes along and tries
to touch something.

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.)

Enable verbose logging, but limit the output of events to only those that
are stale by more than 1ms.
This does not overly pollute the logcat output.

The window manager policy made some incorrect assumptions about the
meaning of the Configuration.keyboard field. We need to be more
careful about distinguishing between built-in and external keyboards.
Most of this change is to move the determination of the parts of
the Configuration related to input devices into the WindowManagerService
leveraging new features of the InputManagerService to good effect.
Then we plumb through the flag that indicates whether a device
is internal or external so that we can be more particular about
how the lid switch effects changes to the Configuration.

Bluetooth devices can be renamed by the user. Make the
input system aware of the user-specified name and transparently
pass it down to applications. This enables the keyboard
layout picker Settings UI to use device names that are
consistent with what the user set in the Bluetooth UI.

The system bar uses input event injection to inject BACK keys
into the application. If the receiving application ANRs, we
used to clear the touch state unconditionally. Doing so would
prevent the system bar from receiving the ACTION_UP event so
the back button would continue to appear pressed until pressed
again.
Now we are more careful to only remove the specific ANR'd
window from the touch state. Other windows should continue
to receive touch events as usual.

Added support for mapping both scan codes and HID usages to
KeyLayoutMap and KeyCharacterMap. Keyboard overlays can

Added the concept of a keyboard layout overlay, which is
a key character map file that has "type OVERLAY".
Added support for loading keyboard layout overlays from
resources dynamically. The layouts are reloaded whenever they
are changed in the Settings application or an application
is installed. This is somewhat more aggressive than necessary
so we might want to optimize it later.
Before system-ready, the input system uses just the generic
keyboard layouts that are included on the device system image.
After system-ready, it considers the user's selected keyboard
layout overlay and attempts to load it as necessary. We need to
wait until system-ready before doing this because we need to
be in a state where it is safe to start applications or access
their resources.

system vibrator which makes it easy for applications to be modified
to use one or the other.
