 #   include_all_resources - If true include all resource IDs in all generated
 #     R.java files.
 #   testonly: Marks this target as "test-only".
 #   write_asset_list: Adds an extra file to the assets, which contains a list of
 #     all other asset files.
 #   alternative_locale_resource_dep: The locale resource target which overrides
 #     any exsting locale resources in dep graph.
 #   requires_sdk_api_level_23: If defined and true, the apk is intended for
 #     installation only on Android M or later. In these releases the system
 #     linker does relocation unpacking, so we can enable it unconditionally.
+#   secondary_native_libs: the path of native libraries for secondary app abi.
 #
 #   DEPRECATED_java_in_dir: Directory containing java files. All .java files in
 #     this directory will be included in the library. This is only supported to
 #     ease the gyp->gn conversion and will be removed in the future.

 # Example
 #   android_apk("foo_apk") {
 #     android_manifest = "AndroidManifest.xml"
 #     java_files = [
 #       "android/org/chromium/foo/FooApplication.java",
