9d3b1a424c Move input library code to frameworks/native.
No longer compile libandroidfw as a static library on the device
since it already exists as a shared library.  Keeping the static
library would force us to provide a static library version of
libinput for the device as well which doesn't make sense.

9f25b7fdf2 Request key maps from input manager service.
Instead of each application loading the KeyCharacterMap from
the file system, get them from the input manager service as
part of the InputDevice object.

Refactored InputManager to be a proper singleton instead of
having a bunch of static methods.

InputManager now maintains a cache of all InputDevice objects
that it has loaded.  Currently we never invalidate the cache
which can cause InputDevice to return stale motion ranges if
the device is reconfigured.  This will be fixed in a future change.

Added a fake InputDevice with ID -1 to represent the virtual keyboard.

fe9f8ab03a 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.

91c69ab015 Add support for arbitrary axes in MotionEvents.
This change makes it possible to extend the set of axes that
are reported in MotionEvents by defining new axis constants.

The MotionEvent object is now backed by its C++ counterpart
to avoid having to maintain multiple representations of the
same data.

3915bb845b 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.

4fe6c3e51b Replace epoll() with poll() and rename PollLoop to Looper.
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.

85a3176704 Add support for secure views.
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
accordingly.

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

42c03e579a Modify native ALooper to take an explicit ident.
The ALooper API now uses an explicit "identifier" for the integer
that is returned rather than implicitly using the fd.  This allows
the APIs that had the fd to be a little more sane.

6d0fec2de3 Refactor input reader to support new device types more easily.
Refactored the input reader so that each raw input protocol is handled
by a separate subclass of the new InputMapper type.  This way, behaviors
pertaining to keyboard, trackballs, touchscreens, switches and other
devices are clearly distinguished for improved maintainability.

Added partial support for describing capabilities of input devices
(incomplete and untested for now, will be fleshed out in later commits).

Simplified EventHub interface somewhat since InputReader is taking over
more of the work.

Cleaned up some of the interactions between InputManager and
WindowManagerService related to reading input state.

Fixed swiping finger from screen edge into display area.

Added logging of device information to 'dumpsys window'.

2c6081ce35 Implement native key pre-dispatching to IMEs.
This significantly re-works the native key dispatching code to
allow events to be pre-dispatched to the current IME before
being processed by native code.  It introduces one new public
API, which must be called after retrieving an event if the app
wishes for it to be pre-dispatched.

Currently the native code will only do pre-dispatching of
system keys, to avoid significant overhead for gaming input.
This should be improved to be smarted, filtering for only
keys that the IME is interested in.  Unfortunately IMEs don't
currently provide this information. :p

c5ed5910c9 Add support for new input sources.
Added several new coordinate values to MotionEvents to capture
touch major/minor area, tool major/minor area and orientation.

Renamed NDK input constants per convention.

Added InputDevice class in Java which will eventually provide
useful information about available input devices.

Added APIs for manufacturing new MotionEvent objects with multiple
pointers and all necessary coordinate data.

Fixed a bug in the input dispatcher where it could get stuck with
a pointer down forever.

Fixed a bug in the WindowManager where the input window list could
end up containing stale removed windows.

Fixed a bug in the WindowManager where the input channel was being
removed only after the final animation transition had taken place
which caused spurious WINDOW DIED log messages to be printed.

d76b67c340 IME events are now dispatched to native applications.
And also:

- APIs to show and hide the IME, and control its interaction with the app.
- APIs to tell the app when its window resizes and needs to be redrawn.
- API to tell the app the content rectangle of its window (to layout
  around the IME or status bar).

There is still a problem with IME interaction -- we need a way for the
app to deliver events to the IME before it handles them, so that for
example the back key will close the IME instead of finishing the app.

85448bbecd Add new glue code for writing native apps.
This factors out the boiler-plate code from the sample
app to a common glue code that can be used for everyone
writing this style of app: a dedicated app thread that
takes care of waiting for events and processing them.

As part of doing this, ALooper has a new facility to allow
registration of fds that cause ALooper_pollOnce() to return
the fd that has data, allowing the app to drive the loop
without callbacks.  Hopefully this makes some people feel better. :)

Also do some other cleanup of the ALooper API, plus some
actual documentation.

682674154e Add new native Looper API.
This allows us to avoid exposing the file descriptor of
the event queue; instead, you attach an event queue to
a looper.  This will also should allow native apps to be
written without the need for a separate thread, by attaching
the event queue to the main thread's looper and scheduling
their own messages there.

3c80a4a044 Implement default key handling for native code.
The native code now maintains a list of all keys that may use
default handling.  If the app finishes one of these keys
without handling it, the key will be passed back off to Java
for default treatment.

a95e4cb62f First stab at attaching native event dispatching.
Provides the basic infrastructure for a
NativeActivity's native code to get an object representing
its event stream that can be used to read input events.

Still work to do, probably some API changes, and reasonable
default key handling (so that for example back will still
work).
