Descriptor bit used with[describeContents()](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#describeContents()): indicates that the Parcelable object's flattened representation includes a file descriptor.

Flag for use with[writeToParcel](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.Int)): the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`". Some implementations may want to release resources at this point.
