Resources and layout direction rendered incorrectly only on Android 8.0 and above

Question

I have a multilingual app with primary language English and secondary language Arabic.

I am calling setLocale() in the onCreate() of every

Answer 1

Resources.updateConfiguration is deprecated use this instead :

 fun setLocale(old: Context, locale: Locale): Context {
    val oldConfig = old.resources.configuration
    oldConfig.setLocale(locale)
    return old.createConfigurationContext(oldConfig)
}

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase?.let { setLocale(it, Locale("ar")) })
}

In Java

private Context setLocale(Context old, Locale locale) {
    Configuration oldConfig = old.getResources().getConfiguration();
    oldConfig.setLocale(locale);
    return old.createConfigurationContext(oldConfig);
}

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(setLocale(newBase, new Locale("ar")));
}
