Android NDK Game Development Cookbook

Android NDK Game Development Cookbook

Overview of this book

Android NDK is used for multimedia applications which require direct access to a system's resources. Android NDK is also the key for portability, which in turn provides a reasonably comfortable development and debugging process using familiar tools such as GCC and Clang toolchains. If your wish to build Android games using this amazing framework, then this book is a must-have.This book provides you with a number of clear step-by-step recipes which will help you to start developing mobile games with Android NDK and boost your productivity debugging them on your computer. This book will also provide you with new ways of working as well as some useful tips and tricks that will demonstrably increase your development speed and efficiency.This book will take you through a number of easy-to-follow recipes that will help you to take advantage of the Android NDK as well as some popular C++ libraries. It presents Android application development in C++ and shows you how to create a complete gaming application. You will learn how to write portable multithreaded C++ code, use HTTP networking, play audio files, use OpenGL ES, to render high-quality text, and how to recognize user gestures on multi-touch devices. If you want to leverage your C++ skills in mobile development and add performance to your Android applications, then this is the book for you.

Introduction

No doubt, any game needs to render some graphics. In this chapter, we will learn how to create a portable graphics rendering subsystem for your game. The chapter is titled Unifying OpenGL ES 3 and OpenGL 3; however, in this book we deal with portable development, so we start our recipes with the OpenGL 3 desktop API. This serves two purposes. First, OpenGL 3 is almost a superset of OpenGL ES 3. This will allow us to port applications between two versions of OpenGL API easily. Second, we can create a simple but very effective wrapper to abstract both APIs from the game code, so that we are able to develop our games on a desktop PC.

Note

OpenGL ES 3 support was introduced in Android 4.3 and Android NDK r9. However, all of the examples in this book are backwards-compatible with the previous version of this mobile API, OpenGL ES 2.

OpenGL itself is a huge topic which merits a dedicated book. We recommend starting with The OpenGL Programming Guide, Pearson Publications (the red book...
