How can multilingual support be implemented in an application?

To implement multilingual support in an Android application, resource files with translations are used. The main steps:

1. Create resource folders for each language, for example:

   • res/values/strings.xml (default)
   • res/values-ru/strings.xml (Russian)
   • res/values-en/strings.xml (English)

2. In each file, define strings with the same keys but in different languages.

3. Android will automatically select the appropriate language based on device settings.

Example of a string in strings.xml:

<string name="welcome_message">Welcome</string>

In the strings.xml for English:

<string name="welcome_message">Welcome</string>

For dynamic language change, you can programmatically change the application's configuration, but this requires additional logic.
