Globalization
Introduction
If OpenHarmony devices and applications need to be used globally, they must meet the requirements of users in different regions on languages and cultures. The Globalization subsystem provides the multi-language and multi-cultural capabilities for global use, including:
-
Resource management
The subsystem loads, parses, and initializes system and application resources based on device types and system configurations, and provides APIs for obtaining resources such as character strings and media files.
-
Internationalization (i18n)
The subsystem provides the bottom-layer resource backtracking capabilities, with a wide array of i18n APIs for implementing functions such as date/time formatting, number formatting, phone number formatting, and singular-plural formatting.
