The Dalvik core libraries team would like to start making warnings
errors in certain packages by definition LOCAL_JAVACFLAGS. This will
allow easier debuging of warnings in other packages by supplying
"-Xlint:..." options.
This lets you use the source code from one apk to build a new one
with a new module name, a new android package name and optionally,
a new certificate.
To use this, in a makefile, add this:
$(call inherit-package, \
packages/apps/Music/Android.mk, \
Music, \
MusicFork, \
my_cert, \
com.example.music)
You don't need the LOCAL_PATH and CLEAR_VARS stuff. It will override
only the packages that are defined in the makefile name you give, but
if other modules of other types are defined, you will get an error
saying that it's defined twice. In that case, you need to move the
duplicate library (for example a .so) out into a different makefile.
A LOCAL_OVERRIDES_PACKAGES entry is automatically created for the
forked app.
Now, by default, instead of fully building everything,
we skip dexing the modules that aren't going to be included
in the current build.
This will slow down some of the incremental builds (like tests),
but it improves the regular eng build from 27.5 minutes on my
Mac Pro to 25 minutes. That's not as much of an improvement
as I had hoped for, but it's still better.
There is also a change in here that puts the java-source-list
file which is used to get around limited command line lengths
in the proper directory. Before this change, it was an
accident that the directory for that file existed!

Implement SDK add-ons in the build system.
- Add an option to use the standard javadoc doclet instead
of droiddoc, since droiddocs non-sdk templates aren't
ready for prime time.
- Add the notion of a stubs for a library. It's only
implemented for java libraries, but when we do native
libraries in the NDK or sdk-addons, it will work there too.
