How can developers implement localization in OutSystems mobile apps?

Implementing localization in OutSystems mobile apps involves creating a flexible and efficient system that can accommodate multiple languages and regional settings. The correct approach is to use resource bundles to manage multiple languages within the app. Resource bundles are files that store key-value pairs, where keys represent text identifiers and their corresponding values are the translations in different languages. This allows developers to easily switch between languages, ensuring that the app can adapt to the user's language preference without significant code changes.

This method not only centralizes the management of translations but also fosters maintainability and scalability. When new languages need to be added, developers can simply introduce a new resource bundle, making it efficient to enhance the app's accessibility to a wider audience.

The other options do not align with best practices for localization. Hardcoding languages within action flows creates inflexibility and makes it difficult to support multiple languages or make updates. Separating apps based on language leads to redundancy and complicates app maintenance, as each variant of the app would need to be managed independently. Translating only UI elements overlooks other aspects of localization, such as date formats, number formats, and cultural differences, which are crucial for a truly localized user experience. Hence, using resource bundles is the most effective and comprehensive method for implementing localization
