Access to string resources from databasehelper

I need to put some default data to database. I made method in my databasehelper:

private void putDefaultList(SQLiteDatabase db){
    String nazwaa = null;
    String mark = "0";

    ArrayList<String> nazwa = new ArrayList<>();
    nazwa.add("jjjjjj");
    nazwa.add("kokoko");

    for (int i =0; i<nazwa.size(); i++) {

        nazwaa = nazwa.get(i);
        db.execSQL("INSERT INTO " + TodoTable.TABLE_NAME + " (" + TodoTable.COL_2 + ", " + TodoTable.COL_3 + ") VALUES (" + "'" + nazwaa + "'" + ", " + "'" + mark + "'" + ")");
    }

This method works but i need to have different languages so the simplest way is to get access to strings.xml but I don't know how in this situation.

I tried Resources.getSystem().getString(R.string.jjjjjj)); but this crash my app.
