Android app internationalization: users can now choose their application language

on YouTube ↗10m

" summary

Android 13 lets apps set per-app languages at runtime using AndroidX. Implement by declaring supported locales with a localeConfig XML in the manifest, call AppCompatDelegate.setApplicationLocales with a one-item LocaleList for runtime switching (handled as an activity restart), and let AndroidX persist choices with the autoStoreLocales manifest flag for pre-T compatibility. Settings app and in-app pickers sync when the runtime API is used, avoiding prior ad hoc storage and API-deprecation complexity.
