Answer 1

Sample Kotlin-Code (null-safe):

writeInt(action?.ordinal ?: -1)

action = readInt().let { if (it >= 0) enumValues()[it] else null }

Which can be encapsulated in a write/readEnum Methods as extensions to Parcel:

fun > Parcel.writeEnum(value: T?) = 
    writeInt(value?.ordinal ?: -1)

inline fun > Parcel.readEnum(): T? = 
    readInt().let { if (it >= 0) enumValues()[it] else null }
