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.

How to read data from sensors

Now we are ready to start acquiring data from I2C sensors. Usually, in order to use an I2C peripheral, we need a driver. A driver is a set of classes that handle the communication between the Android Things board and the peripheral. Moreover, these classes handle the specific protocols implemented by the peripheral. We will describe how to implement a low-level protocol in the next sections. By now, we can use a pre-built driver that is a library we have to include in our project. All the drivers officially supported by Android Things are available at GitHub under the folder contrib-drivers at

Let us start:

  1. Create a new Android Things project by cloning the repository as described in the first chapter.
  2. Open build.gradle and add the following line under the dependencies:
compile ''

Where xx is the version of the driver.

Now you are ready to use the BMP280/BME280 sensor...
