Tried to marshall a Parcel that contained Binder objects.
When passing a ParcelFileDescriptor object with Metadata headers, the following error occurred:

This is because grpc-binder will use Parcel.marshall to serialize Metadata headers into a byte array. But ParcelFileDescriptor cannot be serialized into a byte array, it can only be passed through Parcel.writeParcelable , and then send the Parcel object to the peer.
Is there any way to solve this problem or any other solution?
Can grpc-binder only pass non-binder Parcelable objects?
