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.

How to implement the notification system

Now we are ready to implement the last part of this project: the notification system. In the next paragraphs, we will describe how to send a notification to the user smartphone when motion is detected. As the messaging system, this IoT project uses Google Firebase. This is a cloud platform developed by Google providing several interesting services. We will use the Notification service.

There are several ways we can send a notification from the Android Things app to a user smartphone. To keep things simple, we will use topic. You can imagine a topic like a channel.

Now it is clear the roles these two apps play in this project.

Before implementing it, we have to configure the Firebase...
