How can I programmatically set the language in Jetpack Compose without AppCompatDelegate?

I'm trying to implement language selection functionality in my Jetpack Compose app. However, I encountered a roadblock when attempting to use AppCompactDelegate to achieve this. It seems that AppCompactDelegate is not available in Jetpack Compose.

Here's the code snippet I tried:

fun languageUpdate(context: Context, language: String){
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.TIRAMISU){
            context.getSystemService(LocaleManager::class.java)
                .applicationLocales = LocaleList.forLanguageTags(language)
        } else {
            AppCompactDelegate.setApplicationLocales(LocaleListCompat.forLanguageTags(language))
        }
    }

Since AppCompactDelegate isn't an option in Jetpack Compose, I'm seeking alternative solutions to programmatically set the language in my app. Any guidance or suggestions would be greatly appreciated.

You can combine what Megh Lath proposed, but with a combination of using context.createConfigurationContext for android 12 and above, because resources.updateConfiguration was deprecated for android 12 and on.

val context = LocalContext.current
val resources = context.resources
val configuration = resources.configuration

val newContext = context.createConfigurationContext(configuration.apply {
    setLocale(newLocale)
})
LocalContext.current = newContext

If you want to call AppCompatDelegate.setApplicationLocales(), you can do it in SideEffect block or LaunchedEffect in Jetpack Compose UI, depending on your needs:

SideEffect {   
    AppCompatDelegate.setApplicationLocales()
}

You can directly update the application's configuration using Resources.updateConfiguration() method.

Here's how you can implement it:


fun updateLanguage(context: Context, language: String) {
    val locale = Locale(language)
    Locale.setDefault(locale)

    val configuration = Configuration(context.resources.configuration)
    configuration.setLocale(locale)

    context.resources.updateConfiguration(configuration, context.resources.displayMetrics)
}

And call it through onCreate() or if you want to call it from composable function then cast context as Activity:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    updateLanguage(this, "es")
}

or,

@Composable
fun Sample() {
    val context = LocalContext.current as Activity
    updateLanguage(this, "es")
}
