Book Description

Android is one of the most popular mobile operating systems today. It uses the most popular programming language, Java, as one of the primary languages for building apps of all types. Unlike most other Android books, this book doesn’t assume that you have any prior knowledge of Java programming, instead helps you get started with building Android games as a beginner.

This new, improved, and updated third edition of Learning Java by Building Android Games helps you to build Android games from scratch. Once you've got to grips with the fundamentals, the difficulty level increases steadily as you explore key Java topics, such as variables, loops, methods, object-oriented programming (OOP), and design patterns while working with up-to-date code and supporting examples. At each stage, you'll be able to test your understanding by implementing the concepts that you’ve learned to develop a game. Toward the end, you’ll build games such as Sub Hunter, Retro Pong, Bullet Hell, Classic Snake, and Scrolling Shooter.

By the end of this Java book, you'll not only have a solid understanding of Java and Android basics but will also have developed five cool games for the Android platform.

What you will learn

• Set up a game development environment in Android Studio
• Respond to a player's touch and program intelligent enemies who can challenge the player in different ways
• Explore collision detection, sprite sheets animation, simple tracking and following, AI, parallax backgrounds, and particle explosions
• Animate objects at 60 FPS and manage multiple independent objects using OOP
• Work with design patterns such as OOP, singleton, strategy, and entity-component
• Work with the Android API, the SoundPool API, Paint, Canvas, Bitmap classes, and detect version numbers
