Hello,
We have written new documentation about the NLS External Loader supporting .po files. It allows to easily change languages on Virtual Devices and quickly test changes and updates of a translation. It also works with Crowdin [1] to leverage the assets of the powerful tool used by localization teams.

Happy localization!
