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

,

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?

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)
