Serial Port Usb Android Camera App

I have one custom made device for measuring current. This device can be connected to PC and communication is done over USB. It is based on FTDI chip. I have application written in Java and that application is using rxtxSerial.dll library and gnu.io.rxtx2.1.7.4.jar. Now I want to port this application on my android device and I'm litte bit confused what to do that?

All I have is android tablet (os version 4.1.1), OTG cable and this measuring device.Should my device be rooted? Is there any kind of library that I can simply add to my Java Android application and read data over USB? Where to start?I have tried to port existing application for PC using same library, but rxtxSerial.dll is missing and I can't transfer it to my android device.
