Overview of this book

Machine learning presents an entirely unique opportunity in software development. It allows smartphones to produce an enormous amount of useful data that can be mined, analyzed, and used to make predictions. This book will help you master machine learning for mobile devices with easy-to-follow, practical examples. You will begin with an introduction to machine learning on mobiles and grasp the fundamentals so you become well-acquainted with the subject. You will master supervised and unsupervised learning algorithms, and then learn how to build a machine learning model using mobile-based libraries such as Core ML, TensorFlow Lite, ML Kit, and Fritz on Android and iOS platforms. In doing so, you will also tackle some common and not-so-common machine learning problems with regard to Computer Vision and other real-world domains. By the end of this book, you will have explored machine learning in depth and implemented on-device machine learning with ease, thereby gaining a thorough understanding of how to run, create, and build real-time machine-learning applications on your mobile devices.

Creating a text recognition app using Firebase on-device APIs


To get started in ML Kit, you need to sign in to your Google account, activate your Firebase account, and create a Firebase project. Follow these steps:

  • Go to https://firebase.google.com/.
  • Sign in to your Google account, if you are not already signed in.
  • Click Go to console in the menu bar.
  • Click Add project to create a project and open it.

Now open Android Studio, and create a project with an empty activity. Note down the app package name that you have given while creating the project—for example,  com.packt.mlkit.textrecognizationondevice.

Next, go to the Firebase console. In the Project overview menu, click Add app and give the required information. It will give you a JSON file to download. Add to the app folder of your project in project view in Android Studio, as shown in the following screenshot:

Next, add the following lines of code to the manifest file:

<uses-feature android:name="android.hardware.camera2.full" /<
<uses...
