Answer 1

Something like this should work

 public static class Converter {

    @TypeConverter
    public String fromArray(ArrayList<String> strings) {
        String string = "";
        for(String s : strings) string += (s + ",");

        return string;
    }

    @TypeConverter
    public ArrayList<String> toArray(String concatenatedStrings) {
        ArrayList<String> myStrings = new ArrayList<>();

        for(String s : concatenatedStrings.split(",") myStrings.append(s);

        return myStrings;
    }
}
