    public class MultiDexOffline {
        public static void install(
            SharedPreferences prefs,
            ApplicationInfo applicationInfo,
            String filesDir,
            ClassLoader classLoader
        );
    }

• Please use MultiDexExtractor.PREFS_FILE for the prefences filename, inside of shared_prefs folder under private files app.
