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.

Installing the MQTT server

The last step of this wide IoT project is installing the MQTT server. As you already know, this is the link between the publisher and the subscriber. We added this step at the end because it is not the main focus of this chapter, but it is important to know how to do it so that you gain a deep knowledge about MQTT and the steps necessary to implement an IoT ecosystem that exchanges data and information using MQTT protocol. As stated before, this IoT project uses Mosquitto an open source MQTT broker ( There are several versions working on different operating systems. You can find more information about the platforms supported at this link ( In this project, we will use the Raspberry Pi 2, anyway, you are free to use any version you like according to your needs.

Installing the MQTT broker

To install the MQTT broker you have to connect to Raspberry Pi 2 and follow these steps:

  1. The first step is adding a repository...
