hi guys, is this the right way to use @Parcelize on kotlin sealed classes:

sealed class MySealedClass : Parcelable {
    @Parcelize object Object1: MySealedClass()
    @Parcelize object Object2: MySealedClass()
    @Parcelize object Object3: MySealedClass()
}

I am getting the error:

android.os.BadParcelableException: ClassNotFoundException when unmarshalling: com.myapp.data.MySealedClass$Object1

when try to create the Intent….

i think it needs to be a data class. sealed classes and parcellable will require you to provide your own implementations for write to parcel and other methods

I would also maybe reconsider using parcelables at all. Passing parcelables is widely accepted is an anti pattern.

@Parcelize works with sealed class. Did you set the classLoader? Where is the exception thrown?

[magnumrocha]

@Colton Idle I am not using it with the Jetpack Navigation framework, I am using it to pass data inside my own created Bundle instance, and I don’t know why the Parcelable creation is failing,
@knthmn yeah it should works, I am wondering if this is some Issue with the kotlin object key 🤔

[knthmn]

if you use Bundle you need to set classLoader before calling getParcelable()

[magnumrocha]

@knthmn the issue happens before the reading part of the bundle, specifically it is on the calling of the .startActivity() method on the Activity class…

I mean, my Intent parse code on the other Activity is not being reached.
