# Definitions for building the Java library and associated tests.

#
# Common definitions for host and target.
#

# libcore is divided into modules.
#
# The structure of each module is:
#
#   src/
#       main/               # To be shipped on every device.
#            java/          # Java source for library code.
#            native/        # C++ source for library code.
#            resources/     # Support files.
#       test/               # Built only on demand, for testing.
#            java/          # Java source for tests.
#            native/        # C++ source for tests (rare).
#            resources/     # Support files.
#
# All subdirectories are optional (hence the "2> /dev/null"s below).
