For retrofit2:

@POST("/send")
void upload(@Body RequestBody bytes, Callback cb);

usage:

byte[] params = ...
RequestBody body = RequestBody.create(MediaType.parse("application/octet-stream"), params);
remoteService.upload(body, new Callback() {
    @Override
    public void success(String s, Response response) {
        //Success Handling
    }

    @Override
    public void failure(RetrofitError retrofitError) {
        //Error Handling
    }
});
