      9 # {
     10 #   'target_name': 'aidl_aidl-file-name',
     11 #   'type': 'none',

     22 # }
     23 #
     24 #
     25 # The generated java files will be:
     26 #   <(PRODUCT_DIR)/lib.java/<input-file1>.java
     27 #   <(PRODUCT_DIR)/lib.java/<input-file2>.java
     28 #   ...
     29 #
     30 # Optional variables:
     31 #  aidl_import_include - This should be an absolute path to your java src folder
     32 #    that contains the classes that are imported by your aidl files.
     33 #
     34 # TODO(cjhopman): dependents need to rebuild when this target's inputs have changed.
