The Android must be running firmware 3.1 or greater, and it will need an Android USB host adapter cable, usually referred to as OTG. Please see your manufacturers documentation for the correct part to use. Use a standard USB-miniUSB plug to attach the UniMag (mini-USB port on left side) to the Android host adapter cable.
