On the other hand, if MyData is @Serializable, then it opens the road to many formats at once. You can JSON.stringify(obj) or you can ProtoBuf.dump(obj) and to parcel it you’ll have to have some kind of a helper Parceller class and use it like Parceller.writeTo(parcel, obj). You will not be able just to do parcel.writeValue(obj), because a serializable object does not implement android.os.Parcelable,

[elizarov]

Yes.

However. Android has some ceremony that comes with it. For example, there has to be a public static final CREATOR field. This makes it difficult to simply have a generic solution.
How would this be handled?

[elizarov]

This ceremony is only needed for parcel.readValue(). You will not be to read it like that with serializable. You'll do Parceller.read<MyData>(parcel)
