UART and I2C are simple enough. The underlying Linux drivers should be part of the kernel and you simply open them from /dev in your Android App. The only issue you may have is not having user rights access to them.
What I did was give user access to GPIO, UART, I2C, and SPI from the init.rc and then wrote a JNI to access the /dev or /sys/class/gpio etc. This is assuming you are developing the Android OS build yourself. That certainly makes it easier to set up access rights from init.rc. Check your /dev directory and see if the tty or i2c devices are already present in your build. If so, you just need to check the access rights and write a JNI to use them from an Android App. Dave...
