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.

Handling sensors using the Android sensor framework

The approach described in the previous chapter works if we want to read the pressure and the temperature one shot. In the project we are developing in this chapter, the app has to read the temperature and the pressure continuously. Therefore, it is convenient to use another approach. This approach is the same strategy we implement in Android when the app needs to monitor the smartphone sensors. As you know, nowadays a smartphone has several built-in sensors and to read their values we use the sensor framework provided by Android SDK.

Just to recap briefly how sensor framework works in Android SDK, we can remember that there are key elements that play an important role in these frameworks. These elements are:

  • SensorManager
  • Sensor
  • SensorEvent
  • SensorEventlistener

Luckily, these classes and interfaces are also present in Android Things SDK, and they help us to develop smart Android Things apps easily. The following is a brief description of the most...
