#   'target_name': 'aidl_aidl-file-name',
#   'type': 'none',
#   'variables': {
#     'aidl_interface_file': '<interface-path>/<interface-file>.aidl',

#   'includes': ['<path-to-this-file>/java_aidl.gypi'],
# }
#
#
# The generated java files will be:
#   <(PRODUCT_DIR)/lib.java/<input-file1>.java
#   <(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.
