About

This lesson is going to show you how to release a peripheral driver library in AndroidThings. We’ll discuss just what is a driver library and the benefits of using one. Then we will take an AndroidThings gesture sensor driver library and release it to BinTray and JCenter.

A released driver library is a reusable piece of code that you can run to control a peripheral sensor or actuator at a higher level of abstraction without having to worry about how the peripheral works or its low level communication details. They will be available online to use as a dependency in your own apps or by other people.

When complete, you will understand how to release driver libraries for your Android Things peripherals. You will be able to release your separated driver libraries for cleaner code and potential reuse on your other projects.

This lesson references the code already written for the ZX Sensor in this UART lesson and the Creating a Peripheral IO Driver Library lesson you maybe want to check them out first, although it is not necessary at all.

Hardware Needed

For this lesson, no actual hardware is needed. However if you want to test out the completed demo application. You will need:

  • A Raspberry Pi 3 flashed with Android Things
  • A ZX Gesture Sensor

If you need to buy the Raspberry Pi to start with Android Things I would recommend this kit. It contains:

  • Raspberry Pi 3
  • Rainbow HAT
  • Pibow Coupé for Android Things
  • 2.5A official Raspberry Pi worldwide power supply
  • 8GB microSD card
