It uses the most popular programming language, Java, as the primary language for building apps of all types. However, this book is unlike other Android books in that it doesnt assume that you already have Java proficiency. This new and expanded second edition of Learning Java by Building Android Games shows you how to start building Android games from scratch. The difficulty level will grow steadily as you explore key Java topics, such as variables, loops, methods, object oriented programming, and design patterns, including code and examples that are written for Java 9 and Android P. At each stage, you will put what youve learned into practice by developing a game. You will build games such as Minesweeper, Retro Pong, Bullet Hell, and Classic Snake and Scrolling Shooter games. In the later chapters, you will create a time-trial, open-world platform game. By the end of the book, you will not only have grasped Java and Android but will also have developed six cool games for the Android platform. What you will learn Set up a game development environment in Android Studio Implement screen locking, screen rotation, pixel graphics, and play sound effects Respond to a players touch, and program intelligent enemies who challenge the player in different ways Learn game development concepts, such as collision detection, animating sprite sheets, simple tracking and following, AI, parallax backgrounds, and particle explosions Animate objects at 60 frames per second (FPS) and manage multiple independent objects using Object-Oriented Programming (OOP) Understand the essentials of game programming, such as design patterns, object-oriented programming, Singleton, strategy, and entity-component patterns Learn how to use the Android API, including Activity lifecycle, detecting version number, SoundPool API, Paint, Canvas, and Bitmap classes Build a side-scrolling shooter and an open world 2D platformer using advanced OOP concepts and programming patterns Who this book is for Learning Java by Building Android Games is for you if you are completely new to Java, Android, or game programming and want to make Android games.
