        super.onCreate();

        context = getApplicationContext();
        preferences = PreferenceManager.getDefaultSharedPreferences(context);
        premiumState = preferences.getBoolean("IS_PREMIUM", false);

        //Setting RecyclerView for menu items
        menuItems.add(getString(R.string.menu_item_main_page));
        menuItems.add(getString(R.string.menu_item_convertDate));
        menuItems.add(getString(R.string.menu_item_reminder));

    }
