# The generated java files will be:

#   <(PRODUCT_DIR)/lib.java/<input-file2>.java
#   ...
#
# Optional variables:
#  aidl_import_include - This should be an absolute path to your java src folder
#    that contains the classes that are imported by your aidl files.

# TODO(cjhopman): dependents need to rebuild when this target's inputs have changed.
