// i18n APEX is intended as a home for ICU as of July 2019.
// Various parts and dependencies of ICU would be gradually moved into this APEX,
// and the below build rules should reflect the latest status.
// TODO(b/138434658): Move the apex declaration back to external/icu
// The apex is declared in libcore/ to workaround new dependency from external/icu
// to system/sepolicy in a downstream branch.
