I'm trying to get @Parcelize to generate me the CREATOR for this class:

interface Ringing {
    val token: String
    val other: Uuid
}
interface NoCall

@Parcelize
sealed class JCallState: Parcelable {
    data class IncomingRing(val caller: Uuid, override val token: String) : Ringing, JCallState() {
        override val other: Uuid
            get() = caller
    }
    data class OutgoingRing(val callee: Uuid, override val token: String) : Ringing, JCallState() {
        override val other: Uuid
            get() = callee
    }
    data class Connecting(val callee: Uuid) : JCallState()
    data class InCall(val other: Uuid, val token: String) : JCallState()
    data class Rejected(val other: Uuid) : NoCall, JCallState()
    data class HungUp(val x: String = "foo") : NoCall, JCallState()
}

But when trying to use it in aidl via

parcelable JCallState;

It tells me there is no CREATOR.

Read the documentation. That’s not how the plugin works.
https://developer.android.com/kotlin/parcelize

[reactormonk]

It supports sealed classes according to https://developer.android.com/kotlin/parcelize#parcelize_with_sealed_classes_and_sealed_interfaces

and CREATOR according to https://developer.android.com/kotlin/parcelize#create_data_from_parcel

Which part does it not support?

UUID most probably
https://developer.android.com/kotlin/parcelize#types

[reactormonk]

It's kotlin Uuid, which is Serializable, which is supported according to the documentation

Maybe it’s because how compiler plugins work and when the AIDL generator is invoked.
I’d file an issue to https://issuetracker.google.com/issues/new?component=971607&template=1516698
