How to parcel value with type Any? using @Parcelize

Question

I have encountered with a problem when trying to put value with type Any? into parcel. I'm using @Parcelize from kotlinx.android.parcel. Lint is warning me and hints with message to add @RawValue, but it's not helping. I got:

android.os.BadParcelableException: ClassNotFoundException when unmarshalling

My data class:

@Parcelize
    data class FormulaNode(
            val term: @RawValue Any? = null,
            val operator: String? = null,
            val left: FormulaNode? = null,
            val right: FormulaNode? = null) : Parcelable

You cannot parcel anything which is not parcelable. So instead `Any` use `Parcelable`. — tynn, Nov 02 '18 at 10:56
@tynn But I need something like Any, because `term` can be String or FormulaNode at the same time — Skullper, Nov 02 '18 at 10:59
@JithishPN yup, I have started to put into parcel and get from it by my self, with several checks. This was only solution I found in my case — Skullper, Feb 07 '19 at 08:44
@Skullper please share referal links to do parcel in kotlin ? — Jithish P N, Feb 07 '19 at 08:46
@JithishPN I have no links, it was my solution. You need to implement parcelable by yourself without `@Parcelize`. — Skullper, Feb 07 '19 at 08:53
@Skullper got solution. if raw value(any) is custom class , implement custom class also Parcelable will solve the issue. — Jithish P N, Feb 07 '19 at 09:56
