@ njbuch - The provided libraries do not work on an Android. There is a Java FTDI driver for Android on the other hand. You will need to check to see if your device supports USB Host though. Not all do as Android introduced the software support in 2.2.3. I have a new LG Intuition with 4.0.1 and do not have the option of running USB Host. You will also need to get a compatible USB Host cable for your phone if it does support it.
