      aar_native_libs: The information about collected native libs provided by an aar.
      android_dex_info: The collected Android Dex shards.
      android_resources_info: The collected Android compiled resourses.
      java_resources_info: Java resources info.
      debug_key: A file containing the debug key (deprecated: use debug_signing_keys).
      debug_signing_keys: Debug keystores to be used to sign the apk.
      debug_signing_lineage_file: File containing the signing lineage.
      key_rotation_min_sdk: String of the minimum API level to rotate signing keys for.
      apk: The generated apk for the app.
