Overview of this book

Android Things makes developing connected embedded devices easy by providing the same Android development tools, best-in-class Android framework, and Google APIs that make developers successful on mobile. With this book, you will be able to take advantage of the new Android framework APIs to securely build projects using low-level components such as sensors, resistors, capacitors, and display controllers. This book will teach you all you need to know about working with Android Things through practical projects based on home automation, robotics, IoT, and so on. We’ll teach you to make the most of the Android Things and build enticing projects such as a smart greenhouse that controls the climate and environment automatically. You’ll also create an alarm system, integrate Android Things with IoT cloud platforms, and more. By the end of this book, you will know everything about Android Things, and you’ll have built some very cool projects using the latest technology that is driving the adoption of IoT. You will also have primed your mindset so that you can use your knowledge for profitable, practical projects.

Handle different boards in Android Things

There are two important aspects that we have not covered:

  • How to select the pin to connect the peripherals to
  • How to identify the pin name

Regarding the first aspect, in Raspberry Pi 3 and Intel Edison, but in general for all the boards, the pins do not provide the same features. In other words, we cannot connect the peripherals to a pin by choosing it randomly. We have to select the pin according to the peripheral specifications. In this context it is important to know the pinout of the boards so that we can identify the right pins for our peripherals.

The second aspect is relevant when we want to develop an Android Things app that will run on different boards. As we said in the previous chapter, from the code point of view, this is not a problem because the Java language at the base of Android Things SDK guarantees us that we can run it on all compatible boards. Until now, when we had to identify a pin, we used a double version, one for Raspberry Pi...
