I'm receiving java.lang.AbstractMethodError: abstract method "void android.os.Parcelable.writeToParcel(android.os.Parcel, int)" when putting the app in background, after saving a parcelable (using Parcelize) in onSaveInstanceState :

override fun onSaveInstanceState(outState: Bundle) {
    outState.putParcelable("test", Test())
    super.onSaveInstanceState(outState)
}

@Parcelize
data class Test(val test: String = "test"): Parcelable

It does not occur on configuration changes though. I'm using AS 4.0 Canary 4, with kotlin 1.3.60-eap-25 . Any idea of what am I doing wrong here?

It’s not a root cause but put your data before calling super

Investigating a little further, AbstractMethodError occurs when Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled. 🤔
