🌍 React Native Internationalization for REL-ID IDV SDK

This guide explains how to programmatically set the language in your React Native app using the REL-ID IDV SDK. This feature is useful when your app supports dynamic language switching based on user preferences.

🧾 Overview

Internationalization (i18n) allows users to change the language of your app on the fly. To ensure that the REL-ID SDK reflects the selected language, the SDK must be informed whenever the app locale changes.

🔧 Implementation Steps

1. Import the SDK Client

import RdnaClient from 'react-native-rdna-client';

2. Define a Method to Set Locale

const setApplicationLanguage = (locale: string) => {
  // Examples of locale values: "es" for Spanish, "fr" for French
  RdnaClient.setSDKLocale(locale);
};

3. Usage

Call setApplicationLanguage(locale) whenever the user selects a new language in your app settings or preferences.

📌 Notes

• The locale value should be the standard language code (e.g., "en", "hi", "ja").
• This setting applies to all REL-ID SDK modules: document capture, selfie capture, core, etc.
• The change is applied immediately to all UI components managed by the SDK.

By following these steps, you ensure that REL-ID SDK synchronizes its interface language with your app’s selected locale, enhancing the user experience across different regions.
