  #     final_jni step.
  #   aapt_locale_allowlist: If set, all locales not in this list will be
  #     stripped from resources.arsc.
  #   resource_exclusion_regex: Causes all drawable images matching the regex to
  #     be excluded (mipmaps are still included).
  #   resource_exclusion_exceptions: A list of globs used when

  #     filter out unwanted values/ resources.
  #   shared_resources: True if this is a runtime shared library APK, like
  #     the system_webview_apk target. Ensures that its resources can be
  #     used by the loading application process.
  #   app_as_shared_lib: True if this is a regular application apk that can
  #     also serve as a runtime shared library, like the monochrome_public_apk
  #     target. Ensures that the resources are usable both by the APK running
  #     as an application, or by another process that loads it at runtime.
  #   shared_resources_allowlist_target: Optional name of a target specifying
  #     an input R.txt file that lists the resources that can be exported
  #     by the APK when shared_resources or app_as_shared_lib is defined.
  #   uncompress_shared_libraries: True if shared libraries should be stored
  #     uncompressed in the APK. Must be unset or true if load_library_from_apk
  #     is set to true.
  #   uncompress_dex: Store final .dex files uncompressed in the apk.
  #   strip_resource_names: True if resource names should be stripped from the
  #     resources.arsc file in the apk or module.
  #   short_resource_paths: True if resource paths should be shortened in the
  #     apk or module.
  #   resources_config_paths: List of paths to the aapt2 optimize config files
  #     that tags resources with acceptable/non-acceptable optimizations.
  #   expected_android_manifest: Enables verification of expected merged
  #     manifest based on a golden file.
  #   resource_ids_provider_dep: If passed, this target will use the resource
  #     IDs generated by {resource_ids_provider_dep}__compile_res during
  #     resource compilation.
  #   static_library_dependent_targets: A list of scopes describing targets that
  #     use this target as a static library. Common Java code from the targets
  #     listed in static_library_dependent_targets will be moved into this
  #     target. Scope members are name and is_resource_ids_provider.
  #   static_library_provider: Specifies a single target that this target will
  #     use as a static library APK.
  #   static_library_synchronized_proguard: When proguard is enabled, the
  #     static_library_provider target will provide the dex file(s) for this

  #     use when compiling the sources given to this target (optional).
  #   processor_args_javac: List of args to pass to annotation processors when
  #     compiling sources given to this target (optional).
  #   bundles_supported: Enable Java code to treat this target as a bundle
  #     whether (by default determined by the target type).
  #   main_component_library: Specifies the name of the base component's library
  #     in a component build. If given, the system will find dependent native
  #     libraries at runtime by inspecting this library (optional).

  # Create an Android application bundle from one base android_apk target,
  # and zero or more associated android_apk.
  #
  # Variables:
  #    base_module_target: Name of the android_app_bundle_module target
  #      corresponding to the base module for this application bundle. The
  #      bundle file will include the same content in its base module, though in
  #      a slightly different format.
  #
  #    bundle_base_path: Optional. If set, the bundle will be output to this
  #      directory. Defaults to "$root_build_dir/apks".
  #
  #    bundle_name: Optional. If set, the bundle will be output to the
  #      filename "${bundle_name}.aab".
  #
  #    extra_modules: Optional list of scopes, one per extra module used by
  #      this bundle. Each scope must have a 'name' field that specifies the
  #      module name (which cannot be 'base', since this is reserved for the
  #      base module), and an 'apk_target' field that specified the
  #      corresponding android_apk target name the module is modeled on.
  #
  #    enable_language_splits: Optional. If true, enable APK splits based
  #      on languages.
  #
  #    sign_bundle: Optional. If true, sign the bundle. Default is false
  #      because signing is very slow, and there is no reason to do it
  #      unless one wants to upload the bundle to the Play Store (e.g.
  #      for official builds).
  #
  #    keystore_path: optional keystore path, used only when generating APKs.
  #    keystore_name: optional keystore name, used only when generating APKs.
  #    keystore_password: optional keystore password, used only when
  #      generating APKs.
  #
  #    command_line_flags_file: Optional. If provided, named of the on-device
  #      file that will be used to store command-line arguments. The default
  #      is 'command_line_flags_file', but this is typically redefined to
  #      something more specific for certain bundles (e.g. the Chromium based
  #      APKs use 'chrome-command-line', the WebView one uses
  #      'webview-command-line').
  #
  #    proguard_enabled: Optional. True if proguarding is enabled for this
  #      bundle. Default is to enable this only for release builds. Note that
  #      this will always perform synchronized proguarding.
  #
  #    enable_multidex: Optional. Enable multidexing of optimized modules jars
  #      when using synchronized proguarding. Only applies to base module.
  #
  #    proguard_android_sdk_dep: Optional. android_system_java_prebuilt() target
  #      used as a library jar for synchronized proguarding.
  #
  #    compress_shared_libraries: Optional. Whether to compress shared libraries
  #      such that they are extracted upon install. Libraries prefixed with
  #      "crazy." are never compressed.
  #
  #    system_image_locale_allowlist: List of locales that should be included
  #      on system APKs generated from this bundle.
  #
  #    static_library_provider: Specifies a single target that this target will
  #      use as a static library APK.
  #      Additionally, when allotting libraries to be packaged into modules, the
  #      libraries packaged into the static library will be accounted for to
  #      avoid library duplication. Effectively, the static library will be
  #      treated as the parent of the base module.
  #
  #    expected_libs_and_assets: Verify the list of included native libraries
  #      and assets is consistent with the given expectation file.
  #    expected_libs_and_assets_base: Treat expected_libs_and_assets as a diff
  #      with this file as the base.
  #    expected_proguard_config: Checks that the merged set of proguard flags
  #      matches the given config.
  #    expected_proguard_config_base: Treat expected_proguard_config as a diff
  #      with this file as the base.
  #
  #    version_code: Optional. Version code of the target.
  #
  #    is_multi_abi: If true will add a library placeholder for the missing ABI
  #      if either the primary or the secondary ABI has no native libraries set.
  #
  #    default_modules_for_testing: (optional): A list of DFM that the wrapper
  #      script should install. This is for local testing only, and does not
  #      affect the actual DFM in production.
  # Example:
  #   android_app_bundle("chrome_public_bundle") {
  #      base_module_target = "//chrome/android:chrome_public_apk"
  #      extra_modules = [
  #        { # NOTE: Scopes require one field per line, and no comma separators.
  #          name = "my_module"
  #          module_target = ":my_module"
  #        },
  #      ]
