Hi, To communicate via your USB to serial interface, use Android drivers supplied by the manufacturer. The main USB to serial interfaces to support are Prolific and FTDI. If you Google those two, you can find the Android driver library for each, which you'd include in your project.
I have an Android application which supports these two manufacturers' USB to serial interfaces using their respective drivers, and in the several years the application has been in development, I very rarely come across a user whose device isn't FTDI or Prolific. The Prolific driver is a bit annoying because the latest version intentionally drops support for older Prolific interfaces; a move they apparently did to fight counterfeits, but one which caused many of my users problems. I got around this by using both old and new Prolific drivers in my application. I'm aware that there is an Android USB driver project on Github, but I don't know a great deal about it.
