The Android resource framework provides localization support. On top of the standard Android resource framework, TomTom IndiGO provides additional tooling and additional metadata to facilitate localization.
See Localize Strings for more detailed information about the additional tooling and metadata.
Note: TomTom defines strings in British English. If the U.S. English localization for a string is not (yet) provided by TomTom, the British English string definition is used as a fallback.
