+# This file is a helper to java_apk.gypi. It should be used to create an

+#
+# Required variables:
+#  apk_name - File name (minus path & extension) of the output apk.
+#  apk_path - Path to output apk.
+#  package_input_paths - Late-evaluated list of resource zips.
+#  native_libs_dir - Path to lib/ directory to use. Set to an empty directory
+#    if no native libs are needed.
+# Optional variables:
+#  has_code - Whether to include classes.dex in the apk.
+#  dex_path - Path to classes.dex. Used only when has_code=1.
+#  extra_inputs - List of extra action inputs.
