# Build an SDK jar file out of the generated stubs
# Input variable:
#   sdk_stub_name: the name of the SDK stubs; the stub source code should have been generated to
#                  $(TARGET_OUT_COMMON_INTERMEDIATES)/JAVA_LIBRARIES/$(sdk_stub_name)_intermediates.
#   stub_timestamp: the timestamp file we use as dependency of the generated source.
# Output variable:
#   full_target: the built classes.jar

# The source files for this library are _all_ generated, something we don't do
# anywhere else, and the rules don't support.  Aditionally, the depenencies on
# these files don't really matter, because they are all generated as part of
# building the docs.  So for the dependency, we just use the
# api-stubs-timestamp file, which is the $@ of the droiddoc rule.
# We also need to depend on framework-res.apk, in order to pull the
# resource files out of there for aapt.
#
# Normally the package rule runs aapt, which includes the resource,
# but we're not running that in our package rule so just copy in the
# resource files here.
