Is it possible to write an array without length to a parcel when the length is known?

Methods like this Parcel#readByteArray

are typically used in the examples I've seen:

byte[] _byte = new byte[in.readInt()]; 
in.readByteArray(_byte);

      

        
        
        
      

    

But there is no reason (I see) to write this instead

byte[] _byte = in.createByteArray();

      

        
        
        
      

    

It seems to be read*Array

more useful when the length is known in advance, but write*Array

always records the length. Is there a way to avoid writing it?
