47ab362e8d Use optimized display lists for all hwaccelerated rendering
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.

18092ddc86 Change assets to use 64-bit API
The asset system and supporting libraries were using off_t instead of
off64_t to access files larger than 2GB (32-bit signed). This change
replaces all off_t with off64_t and lseek64.

There is a new utils/Compat.h added for Mac OS compatibility.

Also fixed some size-related compiler warnings.

db360642ed Improve support for external keyboards.
Use Vendor ID, Product ID and optionally the Version to
locate keymaps and configuration files for external devices.

Moved virtual key definition parsing to native code so that
EventHub can identify touch screens with virtual keys and load
the appropriate key layout file.

Cleaned up a lot of old code in EventHub.

Fixed a regression in ViewRoot's fallback event handling.

Fixed a minor bug in FileMap that caused it to try to munmap
or close invalid handled when released if the attempt to map
the file failed.

Added a couple of new String8 conveniences for formatting strings.

Modified Tokenizer to fall back to open+read when mmap fails since
we can't mmap sysfs files as needed to open the virtual key
definition files in /sys/board_properties/.

6688837ff6 Support non-orientation aware keyboards and other devices.
Fixed a bug with dpad keys on external keyboards being rotated
according to the display orientation by adding a new input device
configuration property called "keyboard.orientationAware".

Added a mechanism for overriding the key layout and key character
map in the input device configuration file using the new
"keyboard.layout" and "keyboard.characterMap" properties.

Also added "trackball.orientationAware", "touch.orientationAware" and
"touch.deviceType" configuration properties.

Rewrote the configuration property reading code in native code
so that it can be used by EventHub and other components.

Added basic support for installable idc, kl, and kcm files
in /data/system/devices.  However, there is no provision for
copying files there yet.

Disabled long-press character pickers on full keyboards so that
key repeating works as expected.

a3477c862a Added support for full PC-style keyboards.
BREAKING CHANGE: Redesigned the key character map format to
accomodate full keyboards with more comprehensive suite of modifiers.
Old key character maps will not work anymore and must be updated.
The new format is plain text only and it not compiled to a binary
file (so the "kcm" tool will be removed in a subsequent check-in).

Added FULL keyboard type to support full PC-style keyboards.

Added SPECIAL_FUNCTION keyboard type to support special function
keypads that do not have any printable keys suitable for typing
and only have keys like HOME and POWER

Added a special VIRTUAL_KEYBOARD device id convention that maps
to a virtual keyboard with a fixed known layout.  This is designed
to work around issues injecting input events on devices whose
built-in keyboard does not have a useful key character map (ie.
when the built-in keyboard is a special function keyboard only.)

Modified several places where events were being synthesized
to use the virtual keyboard.

Removed support for the "qwerty" default layout.
The new default layout is "Generic".  For the most part "qwerty"
was being used as a backstop in case the built-in keyboard did
not have a key character map (probably because it was a special
function keypad) and the framework needed to be able to inject
key events anyways.  The latter issue is resolved by using the
special VIRTUAL_KEYBOARD device instead of BUILT_IN_KEYBOARD.

Added the concept of a key modifier behavior so that
MetaKeyKeyListener can distinguish between keyboards that use
chorded vs. toggled modifiers.

Wrote more robust key layout and key character map parsers
to enable support for new keyboard features and user installable
key maps.

Fixed a bug in InputReader generating key ups when keys
are released out of sequence.

Updated tons of documentation.

Currently QwertyKeyListener is being used for full keyboards
with autotext and capitalization disabled.  This mostly works
but causes some problems with character pickers, etc.
These issues will be resolved in subsequent changes.

133cde5805 Add path to get different DPI drawables
Allow a caller to request a different density than their current display
allows. This can mean a device displaying mdpi can get a resource that's
in hdpi and have it pretend to be in mdpi resolution. If a drawable
that's returned is not in the requested density, it will set it at the
appropriate density to be scaled up later on.

The API for this is hidden currently.

6a817e22e4 Add keycodes and meta-key modifiers to support external keyboards.
Added new key maps for external keyboards.  These maps are intended to
be shared across devices by inheriting the "keyboards.mk" product
makefile as part of the device's product definition.

One of the trickier changes here was to unwind some code in
MetaKeyKeyListener that assumed that only the low 8 bits of the meta key
state were actually used.  The new code abandons bitshifts in favor
of simple conditionals that are probably easier to read anyways.
The special meta key state constants used by MetaKeyKeyListener
are now (@hide) defined in KeyEvent now so as to make it clearer that they
share the same code space even if those codes are not valid for KeyEvents.

The EventHub now takes care of detecting the appropriate key layout
map and key character map when the device is added and sets system
properties accordingly.  This avoids having duplicate code in
KeyCharacterMap to probe for the appropriate key character map
although the current probing mechanism has been preserved for legacy
reasons just in case.

Added support for tracking caps lock, num lock and scroll lock and
turning their corresponding LEDs on and off as needed.

The key character map format will need to be updated to correctly support
PC style external keyboard semantics related to modifier keys.
That will come in a later change so caps lock doesn't actually do
anything right now except turn the shiny LEDs on and off...

Added a list of symbolic key names to KeyEvent and improved the toString()
output for debug diagnosis.  Having this list in a central place in the
framework also allows us to remove it from Monkey so there is one less
thing to maintain when we add new keycodes.

61ef747e0e Use pread() in ZipFileRO for Linux
AssetManager instances are created by zygote and passed to all its
children so that they don't have to individually open
frameworks-res.apk. This creates a problem for determining the current
file offset when using lseek() on those files, because you can't
guarantee the cross-process locking of a mutex. Luckily, Linux
implements pread() to get around this suckiness.

The problem is that only Linux implements this, so we have to keep the
old locking for use on host builds with aapt and friends. aapt doesn't
have this same problem of sharing file descriptors across forked
processes, so we can keep the local AutoMutex to protect accesses of
those files.

There is apparently still a race upon reading the entry Local File
Header that can't be tracked down, so move the LFH check inside the
mutex-protected block so we can call lseek again to see where we are
when we log an error.

Also, close() can fail so use TEMP_FAILURE_RETRY on it so we don't
unwittingly leak file descriptors when Mean Mr. EINTR comes a-knocking.

The idea is that if you're writing code that wants fd/events/data on
return from pollOnce() / pollAll() you should really pass in all of those
arguments.  When I changed the Looper API earlier, it was difficult
to ensure that all callers were passing the right parameters since they
were relying on default parameters to some degree so usage mistakes
would not have been caught by the compiler.

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.

a665ca805c Input dispatcher ANR handling enhancements.
This change is essentially a rewrite of the main input dispatcher loop
with the target identification folded in.  Since the input dispatcher now
has all of the window state, it can make better decisions about
when to ANR.

Added a .5 second deadline for processing app switch keys.  This behavior
predates Gingerbread but had not previously been ported.

Fixed some timing inaccuracies in the ANR accounting that could cause
applications to ANR sooner than they should have.

Added a mechanism for tracking key and motion events that have been
dispatched to a window so that appropriate cancelation events can be
synthesized when recovering from ANR.  This change helps to keep
applications in sync so they don't end up with stuck buttons upon
recovery from ANRs.

Added more comments to describe the tricky parts of PollLoop.

rather than being decompressed in their entirety and held in memory.  Reading
the data in order is relatively efficient, as is seeking forward in the stream.
Seeking backwards is supported, but requires reprocessing the compressed data
from the beginning, so is very inefficient.

In addition, the size limit on compressed assets has been eliminated.

0a128e3cbe Fix bug with phantom input windows.
Add dumpsys integration for the native input dispatcher.
Add some InputDevice API stubs.
Add an appendFormat helper method to String8 for printf style
string formatting mainly for debugging purposes.
Use generic ArrayList<WindowState> everywhere in WindowManagerService
to eliminate unnecessary casts all over.

3c5d125ed7 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.
