Arduino USB host android tablet send and receive data?

Okay so I had just purchased a usb host controller for my Arduino mega (http://www.ebay.com/itm/251631192067?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

I am planning on hooking this Arduino module up to an android tablet. I have watched plenty of youtube tutorial showing how to connect an android tablet to your Arduino with one of these modules. And basically have the tablet send data to the Arduino mega board :)

But my question is can this work in reverse can the Arduino send data to the android tablet. (Basically my question is can they talk freely back and forth?)

Thank you for all help
