...for Market App iRunner
There were a lot of serious issues with how we updated (or often didn't update)
the display and resource state when switching compatibility mode in conjunction
with restarting and updating application components. This addresses everything
I could find.
Unfortunately it does *not* fix this particular app. I am starting to think this
is just an issue in the app. This change does fix a number of other problems
I could repro, such as switching the compatibility mode of an IME.
Also a few changes here and there to get rid of $#*&^!! debug logs.
Change-Id: Ib15572eac9ec93b4b9966ddcbbc830ce9dec1317
this bug was introduced recently. it caused RefBase's weakref_impl
structure to be leaked for every RefBase object (about 20 bytes).

Bug: 4364920
Velocity damping proved to be a bad idea because it would
cause a significant ramp in velocity at the beginning of
a gesture, instead of the desired smooth behavior. Oh well.

Fix a race that could cause GL commands to be executed from the wrong thread.
RefBase subclasses can now decide how they want to be destroyed.
Fix a race in SurfaceFlinger that could cause layers to be leaked forever.
Fix a race-condtion in SurfaceFlinger that could lead to a crash.
initial cherry-pick:
resolved conflicts for merge of b9783b49 to honeycomb-plus-aosp

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.

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.
Change-Id: Ibc6abf8af027d9003011ac75caa12941080caba3
Added a timeout mechanism to EventHub and InputReader so that
InputMappers can request timeouts to perform delayed processing of
input when needed.

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.

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.

You can now specify resource configuration variants "wNNNdp"
and "hNNNdp". These are the minimum screen width/height in "dp"
units. This allows you to do things like have your app adjust
its layout based only on the about of horizontal space available.
This introduces a new configuration change flag for screen size.
Note that this configuration change happens each time the orientation
changes. Applications often say they handle the orientation change
to avoid being restarted at a screen rotation, and this will now
cause them to be restarted. To address this, we assume the app can
handle this new config change if its target SDK version is < ICS.

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.

a memory corruption happned when the buffer pool was resized
(like when playing a video or using camera) and there was
no current active buffer. In this case, the faulty code
would index into an array at position -1 which corrupted
24 bytes of data.
also improved region validation code (ifdef'ed out by default)

This change makes the ANativeWindow_lock NDK function error out if it is
passed an ANativeWindow with a concrete type that is not Surface. It
also makes eglCreateWindowSurface fail if it is passed a
SurfaceTextureClient as its 'window' argument.
Bug: 4087277
Change-Id: Ie68c50c52d88f72d8a387f6c094908044c83a88c
This change adds a getter method to SurfaceTextureClient to get the
ISurfaceTexture object with which the SurfaceTextureClient is
communicating.
Bug: 4086509
Change-Id: Ifec621e0fe5392a5be56b2348fdc54067cbebcdd
This change adds a query to the ANativeWindow interface for getting the
concrete type of the ANativeWindow.

This change fixes the transform matrix computation in SurfaceTexture
when a crop rectangle is specified by the image producer. It also adds
a test for this case as well as a basic test for the uncropped case.

Change-Id: I1481c9ce9d08fe7f2bff86d3afdeab7d4002b157
This change makes SurfaceFlinger treat layers for which the active
buffer has the GRALLOC_USAGE_PROTECTED bit set as if they have the
'secure' flag set.

Bug: 4081304
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)
Change-Id: I0189e18e464338f126f7bf94370b928e1b1695f2
This change adds a new 'method' to the ANativeWindow interface to check
whether buffers queued to the window will be sent directly to the system
window compositor.

Bug: 3495535
Ensure that the joystick can always reach -1.0, 0.0 and 1.0 positions
even when noise filtering is applied. (Bug: 3514510)
Add support for a few more standard axes.
Add additional mapping modes for axes.
Some axes are inverted from standard interpretation
or are actually intended to be split into two distict axes
such as left/right trigger controls or accelerator/brake.
Add key layout file for a G25 racing wheel and XBox 360 controller
to tweak behavior. They work fine without them but the axis mappings
are not ideal.
Change-Id: I0fddd90309af4dc14d35f34fe99ed6e521c0b7c7
Added some plumbing to enable the policy to intercept motion
events when the screen is off to handle wakeup if needed.
Added a basic concept of an external device to limit the scope
of the wakeup policy to external devices only. The wakeup policy
for internal devices should be based on explicit rules such as
policy flags in key layout files.
Moved isTouchEvent to native.
Ensure the dispatcher sends the right event type to userActivity
for non-touch pointer events like HOVER_MOVE and SCROLL.

Fades out the mouse pointer:
- after 15 seconds of inactivity normally
- after 3 seconds of inactivity in lights out mode
- after a non-modifier key down
- after a touch down
Extended the native Looper to support enqueuing time delayed
messages. This is used by the PointerController to control
pointer fade timing.

This change adds a new query to ANativeWindow for getting the minimum
number of buffers that must be left un-dequeued during the steady-state
operation of the ANativeWindow.

This change adds a null pointer check before dereferencing buffers in
a Surface list of known GraphicBuffer objects. If not all the buffers
have been dequeued before this list can legitimately contain NULL
entries.

some of the conversion operators were not using the proper
pointer type when calling incStrong/decStrong, usually it
has no bad consequences, but for some implementation
of the ref-counted object it could lead to recording the wrong
owner id.
Change-Id: If574b9069b8a4cf6e0911a992c8f095aba799995
First slipt sp<> out of RefBase into StrongPointer.h so it can be reused
more easily and to make it clear that it doesn't require RefBase.
Note: the rest of the change only affects the system when DEBUG_REFS is enabled.
The main problem we fix here is that the owner id associated with each
reference could get out of date when a sp<> or wp<> was moved, for
instance when they're used in a Vector< >.
We fix this issue by calling into RefBase::moveReferences from
a template specialization for sp<TYPE> and wp<TYPE> of the
type helpers. RefBase::moveReferences() has then a chance to
update the owner ids.
There is a little bit of trickery to implement this generically in
RefBase, where we need to use a templatized functor that can turn
a sp<TYPE>* casted to a void* into a RefBase*.
Introduced a new debug option DEBUG_REFS_FATAL_SANITY_CHECKS
currently set to 0 by default as there seem to be an issue
with sp<ANativeWindow> which trips the sanity checks.
Change-Id: I4825b21c8ec47d4a0ef35d760760ae0c9cdfbd7f
Added support for tracking the mouse position even when the mouse button
is not pressed. To avoid confusing existing applications, mouse movements
are reported using the new ACTION_HOVER_MOVE action when the mouse button
is not pressed.
Added some more plumbing for the scroll wheel axes. The values are
reported to Views but they are not yet handled by the framework.
Change-Id: I1706be850d25cf34e5adf880bbed5cc3265cf4b1
Added API on InputDevice to query the set of axes available.
Added API on KeyEvent and MotionEvent to convert keycodes and axes
to symbolic name strings for diagnostic purposes.
Added API on KeyEvent to query if a given key code is a gamepad button.
Added a new "axis" element to key layout files to specify the
mapping between raw absolute axis values and motion axis ids.
Expanded the axis bitfield to 64bits to allow for future growth.
Modified the Makefile for keyboard prebuilts to run the keymap
validation tool during the build.
Added layouts for two game controllers.
Added default actions for game pad button keys.
Added more tests.
Fixed a bunch of bugs.

HAVE_ANDROID_OS was defined as "1" for targets, but never defined as "0"
for non-targets. Changing them to #ifdef should be safe and matches
all the other uses of HAVE_ANDROID_OS throughout the system.
Change-Id: I82257325a8ae5e4e4371ddfc4dbf51cea8ea0abb
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.
