How is it possible to upload large files with Volley? ( Android )

I would like to upload large files in a POST request using Volley. I tried to use a VolleyMultiPartRequest library, but I get java.lang.OutOfMemoryError:

All of the libraries like VolleyPlus MultiPartRequest overrides the function public byte[] getBody(). This seems to be the problem, because if a large file is converted into a byte array, then it can not fit into the memory. I need to send the request in chunks. How is that possible?
