  Mastering Per-App Language Preferences: From Android 10 to Android 13+ One of the most requested features by users is the ability to use an app in a language different from the system language. While Android 13 (API 33) introduced "Per-App Language" settings at the system level, implementing this backward-compatibly for older devices like Android 10 (API 29) used to be a challenge involving manual configuration wrapping. Today, thanks to AppCompat 1.6.0+ , we have a unified, standard way to handle this. Here is the modern guide to implementing seamless language switching. The Architecture: How it Works On Android 13 and above, the system handles the storage and application of your app's locale. On older versions, the AppCompat library manages this behavior by storing your preference in an internal XML file and injecting the resources during the activity lifecycle.

In this guide, we’ll look at how to streamline your initialisation using the App Startup Library and ensure a seamless visual transition with the Android 12 Splash Screen API (with full backward compatibility for API 29).

The Jetpack App Startup library allows all components to share a single content provider, significantly improving performance. Why use it? Performance: Shared content provider reduces overhead. Order: Explicitly set the initialisation sequence. Simplicity: Both library creators and app developers use a unified interface. Part 2: The Modern Splash Screen API Starting ...
