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.

🤔
