To add a language that is not supported by the Face SDK or change the localized strings displayed by the SDK, you need to add localized strings to the strings.xml file redefining every localizable string resource with the appropriate translated values.

This way, when a user has their device's System Language set to a language supported by your application, the Face SDK will utilize the appropriate string resources.

In order to do it, you need to know the identifiers of the strings, which are available in the values.xml file provided with the latest release version.

To see all the localization keys, look up the values.xml file at: External Libraries -> Gradle: com.regula.face:api:X.X.X@aar -> res -> values -> values.xml


For additional information on how you can localize your Android application, please see the official Android Documentation.
