how can I solve this ‘no args’ issue

[Czar]

what are you parsing it with? GSON?

[sudhanshu singh]

yes

[Czar]

You could try using InstanceCreator like GSON docs suggest, but GSON + Kotlin is not an ideal combination, I'd either use jackson with kotlin module registered or kotlin-specific lib, like klaxon or koshi

[Konstantin]

Why don't you make it enum class then?

[Czar]

Another problem here is val type: MenuTypeModel serializer will try to instantiate the parent instead of MAP, CALENDAR or LEADERBOARD which you probably want.

[sudhanshu singh]

I am trying to avoid using enum in Android as it is recommended by many not to use enums

[Czar]

It is recommended not to use Enums only to save up on memory and CPU when you can do the same thing with a constant, by using sealed classes you are defeating the purpose of avoiding enums

[sudhanshu singh]

oh.

[sudhanshu singh]

I should go back to using stringDef then.

[Czar]

yeah, use of enum in this case is (probably) lighter than sealed classes 🙂 In the future always check why something is or isn't recommended.

[gildor]

In general It’s completely fine to use Enums on Android.
If Enum or Sealed class solves your problem just use it. At least it’s more type safe than StringDef

[gildor]

In your case I don’t see any reason to use Sealed class instead of Enum.
