This display can be controlled with either SPI or serial TTL communication. However, since the SPI pins are required for communication with the USB Host, TTL serial must be used (this also requires fewer pins, one instead of three). So, connect the RX pin on the serial display to the serial TX pin on the Arduino (determined by the firmware sketch) and connect GND and VCC on the serial display to ground and+5v respectively. Here is a diagram of the completed circuit (created with Fritzing):
Next, upload the Arduino sketch to the microcontroller. The sketch uses the Microbridge implementation by Niels Brouwers. Microbridge uses Android Debug Bridge (ABD) forwarding over TCP, rather than the Google Android ADK. You can checkout the source for the Arduino sketch from Github, or just copy and paste the following into the Arduino IDE.
