8e19c2e97e fix a crasher in SurfaceTexture::updateTexImage()
we now make sure to drain the buffer queue on disconnect.
this happens only when in synchrnous mode. in async mode
we clear all buffers except the head of the queue.

for extra safety we also catch the null pointer
in updateTexImage (which should  never happen) and return
an error.

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.

5aa3d79025 Fix getSwitchState according to device capabilities.
When querying switch state for a given device id, ensure that the device
exposes the given switch in its capabilities, report AKEY_STATE_UNKNOWN
otherwise.
This fix a bug in InputManager that reports an incorrect switch state
(down) when a device exposes at least one switch in its capabilites and
another switch is queried. For example, this can leads in always
reporting LID state open (SW_LID down) if only SW_HEADPHONE_INSERT is
exposed in capabilities.

49a65e5526 Move extract native libraries to JNI code
The built-in ZipFile class was quite a long time to find an unpack
libraries. Move everything to using the libutils ZipFileRO class that
goes quite a bit faster. Initial measurements are 6 times faster than
the Java code.

Also, read files off the disk and compare their CRC against the APK's
CRC to see if we need to write the new file to disk. This also cuts down
the bootup time by up to a second per APK that has native files.

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.

bee205fd58 EGL: fix the ANativeWindow size/fmt override
This change fixes how the Android EGL layer overrides the size and
format of an ANativeWindow in eglCreateWindowSurface.  The new behavior
is to leave the size untouched when overriding the format.  The previous
behavior was to reset the ANativeWindow to use the default size set by
the ANativeWindow implementation.

It also adds two new 'perform' methods to the ANativeWindow interface:
set_buffers_dimensions and set_buffers_format, and redefines the
behavior of set_buffers_geometry to be the combination of these two new
methods.

Additionally, this change adds an error check for the return value of
the new native_window_set_buffers_format call, which required adding a
(stub) handler for to FramebufferNativeWindow.

3d8063b02e SurfaceTexture: change onFrameAvailable behavior
This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class.  The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer.  This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed.  Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.

The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves.  This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

736aa9573b SurfaceTexture: fix a getTransformMatrix crash.
This change moves the computation of the transform matrix out of
getTransformMatrix and instead performs the computation when
updateTexImage gets called.  This is needed in order for
getTransformMatrix to succeed even if the buffers have been freed (e.g.
by changing the buffer count) because the computation depends upon the
properties of the current GraphicBuffer.

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.

d3e6d3e763 Initial checkin of spot presentation for touchpad gestures. (DO NOT MERGE)
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.

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

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.

88c0d696cc DO NOT MERGE. Integrate add new screen width/height in "dp" configs.
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.

c04f153353 Fix a bug where setgeometry couldn't be undone
This change the binder protocol between SurfaceTextureClient
and SurfaceTexture. dequeueBuffer() now takes the requested
parameters for the buffer. SurfaceTexture decides if the
buffer needs to be reallocated and does the allocation
if needed. In that case it returns BUFFER_NEEDS_REALLOCATION
to tell SurfaceTextureClient that it needs to call
requestBuffer (which all parameters have been removed) to
acquire a pointer to the buffer.

dequeueBuffer and requestBuffer could be folded into a single
IPC call, but we chose to optimize the case where buffers are
not created and avoid some complexity in the marshalling code.

d78797f6e6 Full local backup infrastructure
This is the basic infrastructure for pulling a full(*) backup of the
device's data over an adb(**) connection to the local device.  The
basic process consists of these interacting pieces:

1. The framework's BackupManagerService, which coordinates the
   collection of app data and routing to the destination.

2. A new framework-provided BackupAgent implementation called
   FullBackupAgent, which is instantiated in the target applications'
   processes in turn, and knows how to emit a datastream that contains
   all of the app's saved data files.

3. A new shell-level program called "bu" that is used to bridge from
   adb to the framework's Backup Manager.

4. adb itself, which now knows how to use 'bu' to kick off a backup
   operation and pull the resulting data stream to the desktop host.

5. A system-provided application that verifies with the user that
   an attempted backup/restore operation is in fact expected and to
   be allowed.

The full agent implementation is not used during normal operation of
the delta-based app-customized remote backup process.  Instead it's
used during user-confirmed *full* backup of applications and all their
data to a local destination, e.g. via the adb connection.

The output format is 'tar'.  This makes it very easy for the end
user to examine the resulting dataset, e.g. for purpose of extracting
files for debug purposes; as well as making it easy to contemplate
adding things like a direct gzip stage to the data pipeline during
backup/restore.  It also makes it convenient to construct and maintain
synthetic backup datasets for testing purposes.

Within the tar format, certain artificial conventions are used.
All files are stored within top-level directories according to
their semantic origin:

apps/pkgname/a/  : Application .apk file itself
apps/pkgname/obb/: The application's associated .obb containers
apps/pkgname/f/  : The subtree rooted at the getFilesDir() location
apps/pkgname/db/ : The subtree rooted at the getDatabasePath() parent
apps/pkgname/sp/ : The subtree rooted at the getSharedPrefsFile() parent
apps/pkgname/r/  : Files stored relative to the root of the app's file tree
apps/pkgname/c/  : Reserved for the app's getCacheDir() tree; not stored.

For each package, the first entry in the tar stream is a file called
"_manifest", nominally rooted at apps/pkgname.  This file contains some
metadata about the package whose data is stored in the archive.

The contents of shared storage can optionally be included in the tar
stream. It is placed in the synthetic location:

shared/...

uid/gid are ignored; app uids are assigned at install time, and the
app's data is handled from within its own execution environment, so
will automatically have the app's correct uid.

Forward-locked .apk files are never backed up.  System-partition
.apk files are not backed up unless they have been overridden by a
post-factory upgrade, in which case the current .apk *is* backed up --
i.e. the .apk that matches the on-disk data.  The manifest preceding
each application's portion of the tar stream provides version numbers
and signature blocks for version checking, as well as an indication
of whether the restore logic should expect to install the .apk before
extracting the data.

System packages can designate their own full backup agents.  This is
to manage things like the settings provider which (a) cannot be shut
down on the fly in order to do a clean snapshot of their file trees,
and (b) manage data that is not only irrelevant but actively hostile
to non-identical devices -- CDMA telephony settings would seriously
mess up a GSM device if emplaced there blind, for example.

When a full backup or restore is initiated from adb, the system will
present a confirmation UI that the user must explicitly respond to
within a short [~ 30 seconds] timeout.  This is to avoid the
possibility of malicious desktop-side software secretly grabbing a copy
of all the user's data for nefarious purposes.

(*) The backup is not strictly a full mirror.  In particular, the
    settings database is not cloned; it is handled the same way that
    it is in cloud backup/restore.  This is because some settings
    are actively destructive if cloned onto a different (or
    especially a different-model) device: telephony settings and
    AndroidID are good examples of this.

(**) On the framework side it doesn't care that it's adb; it just
    sends the tar stream to a file descriptor.  This can easily be
    retargeted around whatever transport we might decide to use
    in the future.

KNOWN ISSUES:

* the security UI is desperately ugly; no proper designs have yet
  been done for it
* restore is not yet implemented
* shared storage backup is not yet implemented
* symlinks aren't yet handled, though some infrastructure for
  dealing with them has been put in place.

  Better compat mode part one: start scaling windows.

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.
