On Android / Nexus 7 I use a  Terminal emulator with a USB-OTG adapter on
the tablet and an FDDI to serial adapter connected to the USART on the uC.

If you want to write your own android app in place of the terminal it
should work just as well with the same hardware but I
haven't personalty done so.

Cheers
Chris
