如果已成功使用Parcelised数据，即使我已退出Parcelised数据，我退出应用程序时Android应用程序也会崩溃

Question

I have a strange crash on both the Genymotion Android simulator and my Huawei Nexus 6P . I have a screenshot that I am sending to another Anko Component successfully - obviously it is Parcelable:

@Parcelize
data class ColourBoardScreenShot(var screenshot: @RawValue BitmapDrawable) : Parcelable

However, if I take the screenshot and anytime later quit the app by pressing the circle button at the bottom of the screen the app crashes with the following stack trace:

FATAL EXCEPTION: main

Can anyone tell me where I'm going wrong?

EDIT :

If I try and replace the ColourBoardScreenShot by using a plugin to generate the Parcelize code I get Unresolved reference on read and write :

data class ColourBoardScreenShot(var screenshot: @RawValue BitmapDrawable) : Parcelable {
constructor(source: Parcel) : this(
        source.read[@kotlinx.android.parcel.RawValue] BitmapDrawable ()
)

override fun describeContents() = 0

override fun writeToParcel(dest: Parcel, flags: Int) = with(dest) {
    write[@kotlinx.android.parcel.RawValue] BitmapDrawable (screenshot)
}

companion object {
    @JvmField
    val CREATOR: Parcelable.Creator<ColourBoardScreenShot> = object : Parcelable.Creator<ColourBoardScreenShot> {
        override fun createFromParcel(source: Parcel): ColourBoardScreenShot = ColourBoardScreenShot(source)
        override fun newArray(size: Int): Array<ColourBoardScreenShot?> = arrayOfNulls(size)
    }
}
}

Answer 1

I changed my ColourBoardScreenShot to the following:

@Parcelize
data class ColourBoardScreenShot(var screenshot: ByteArray) : Parcelable

So instead of @RawValue BitmapDrawable I use ByteArray and the crash stopped.
