This changes the names of the directories in aapt, to what you see
in the list of DpiTest resources. Also adds a new "long" configuration
for wide screens, which the platform sets appropriate, and introduces
a new kind of resizeability for not large but significantly larger
than normal screens which may have compatibility issues.
A small optimization to the resource code, to not re-parse the framework
resources every time we build a new AssetManager. Instead, you can now
construct a ResTable from a previously created one... of course, like the
existing code for using the data in-place, you can't delete the original
ResTable until you have deleted the one that has been constructed from it.
It turns out this was not a problem in the resource code at all. Rather,
the system process has a cache of pre-loaded attributes it uses to avoid
continually reloading things as it needs them. Well it turns out this
cache wasn't flushed after a package was uninstalled or a configuration
changed, so you could re-install an app where you change its style resources
so its theme now points to one that is inconsistent in the cache.
This is mostly a problem for developers, where they continually install
new versions of an app where resources have changed. This could possibly
show up when updating an app on a normal phone, although the problem would
eventually correct itself since this cache uses weak references.
Anyway, the cache is now reworked to be flushed appropriately.
This change also includes an update to aapt to be able to dump the
contents of bags in resources.
Applications can now declare that they support small, normal, or
large screens. Resource selection can also be done based on these
sizes. By default, pre-Donut apps are false for small and large,
and Donut or later apps are assumed to support all sizes. In either
case they can use <supports-screens> in their manifest to declare
what they actually support.
This change puts the file's access mode into the saved-state blob used by the
file backup helpers. The tests have been updated for the new blob content
format.
What this change *doesn't* do is actually backup/restore the file mode. This
change is a prerequisite for that, but mode preservation in backup/restore will
require adding metadata to the backup data stream itself, so will be approached
a bit more carefully.
(Also fixed one outright bug in the test program: ReadEntityData() had been
changed to return a ssize_t union of either a byte-count or a negative number
indicating error, but the test program was still assuming that nonzero == error,
and was spuriously failing.)
The aapt tool now reports all available densities like it already did
for locales. Also this includes more resource data output, which I
was using to examine bug #1867049 (which at this point I am unable to
reproduce).
* changes:
Add support for changing a threads scheduler group. Three groups are available (default, background non interactive, foreground boost). Setting a thread priority to PRIORITY_BACKGROUND will transparently change groups to background

Fix runtime resource selection logic.
Fix isBetterThan so that o or this may be supperior at any stage.
Used to only handle this-better or tie at each stage, biasing against o.
Also allows reset of unit test to succeed. Fixes bug 1709202.
