@Implementation
    public void writeStrongBinder(IBinder binder) {
      int id = nextBinderId.getAndIncrement();
      binderMap.put(id, binder);
      realObject.writeInt(id);
    }
ShadowParcel doesn't correctly handle {@link Parcel#writeStrongBinder(IBinder)} or {@link
Parcel#readStrongBinder()}, so we shim a simple implementation that uses an in-memory map to
read and write Binder objects.
