Custom region/language

Batch allows you to set a custom region or a custom language that will override the value detected by the SDK. By default, Batch collects the language and the country of your users' devices.

Setting a custom region/language is useful if:

You don't want to use the values detected by Batch.
Your users can choose their own language or region for localization purposes.

Here is how to set a custom region/language:

BatchUser.instance.newEditor()
  .setLanguage("en") // Language must be 2 chars, lowercase, ISO 639 formatted
  .setRegion("US") // Region must be 2 chars, uppercase, ISO 3166 formatted
  .save();

To unset the custom language/region, use null.
