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.

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.

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.

This leak was intentional, it was there to deal with the fact that
some gralloc implementations don't track buffer handles with
file-descriptors so buffers needed to stay alive until there were
registered, which is not guaranteed by binder transactions.
In this new implementation, we use a small BBinder holding a
reference to the buffer, which with tuck into the parcel. This forces
the reference to stay alive until the parcel is destroyed, which
is guaranteed (by construction) to happen after the buffer is
registered.
this allows the public facing API to not expose the previous hack.

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.

This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications. At this time,
the mechanism is only intended to be used by the accessibility
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.

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.

There are two areas that have changed to eliminate the assumption that
local jobject references are both canonical and persistent:
1. JavaBBinderHolder no longer holds onto and reuses it parent object
reference per se. Since the underlying JavaBBinder object holds a
real global ref, this was redundant anyway. Now, for purposes of its
transient need to perform JNI operations, it simply uses the current
jobject ref(s) passed during method invocation, and no longer attempts
to hold these refs beyond the scope of a single invocation.
2. Binder obituaries no longer assume that a jobject reference to a
recipient will always compare == as a 32-bit value with any future

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.

The touch screen sometimes reports more than 10 pointers even though that's

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.

Generally we never want to lock a buffer for write access if it is at
the "head" on the surfaceflinger side. The only exception (1) is when
the buffer is not currently in use AND there is at least one queued
buffer -- in which case, SurfaceFlinger will never use said buffer
anymore, because on the next composition around, it will be able to
retire the first queued buffer.
The logic above relies on SurfaceFlinger always retiring
and locking a buffer before composition -- unfortunately this
didn't happen during a screenshot.
This could leave us in a situation where a buffer is locked by the
application for write, and used by SurfaceFlinger for texturing,
causing a hang.
Here, we fix this issue by never assuming the exception (1), it was
intended as an optimization allowing ANativeWindow::lockBuffer() to
return sooner and was justified when most of SF composition was
done in software. The actual buffer locking is now ensured by
gralloc. We could have handled screenshots in a similar way to
a regular composition, but it could have caused glitches on screen,
essentially, taking a screenshot could cause to skip a frame.
now that we removed the notion of a "inUse" buffer in surfaceflinger
a lot of code can be simplified / removed.
noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete"
is also gone.
Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

InputReader::getSwitchState always returns AKEY_STATE_UNKNOWN
because SwitchInputMapper::getSources() returns 0 which cannot
match any source mask including AINPUT_SOURCE_ANY. As a result
initial lid switch detection is broken.
This change adds a new source constant AINPUT_SOURCE_SWITCH
that indicates that the source has switches.

This change implements the onFrameAvailable callback for the
SurfaceTexture java class. It includes the C++ SurfaceTexture code as
well as the JNI and Java code to enable the callback.

when we validate the surface there, most errors are in fact allowed
because it is legal to cancel a buffer after a surface has been
destroyed (for instance). in that case make sure to not log
error messages as they are very confusing.

This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger. This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.

This change adds support for the setCrop and setTransform methods of the
SurfaceTexture C++ class. The crop and transform for the current
texture will be accessed by applications as a single texture coordinate
transform matrix.

Adds a new virtualKeyQuietTimeMillis configuration resource that sets
the duration for which virtual keys will be dropped after recent touches
on screen. The default value is 0; it is intended to be overridden
per device using a resource overlay.
This change is designed to help in two cases:
1. Swipes from touchscreen into virtual key area.
2. Accidental taps in virtual key area while using on-screen keyboard.

We need to reset mCurrentTexture and mLastQueued in setBufferCount
because it frees all of the buffers associated with the buffer slots.

This change adds the C++ implementation of SurfaceTexture and related
classes. The goal of this is for a SurfaceTexture to be passed to
camera service or Stagefright in place of a Surface to allow camera
preview or decoded video frames to be streamed to an OpenGL ES texture
that an application can use.

This change adds a new binder method to the ISurfaceComposer interface.
This IPC is intended to allow SurfaceFlinger clients to allocate gralloc
buffers using SurfaceFlinger as a proxy to gralloc.

Added support for loading the pointer icon from a resource.
Moved the system server related bits of the input manager out
of libui and into libinput since they do not need to be linked into
applications.

Make the output from aapt dump --values resources and aapt dump xmltree normalized, so that it is unambigously displayed
regardless of the content of the strings.
