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.

Initializing OpenAL and playing the .wav files


In this recipe, we present the simplest possible example to play uncompressed audio files in PCM format (pulse-code modulation, http://en.wikipedia.org/wiki/Pulse-code_modulation). This example just plays a single file in an infinite loop. We will create a single device, a single device context, and an audio source. All of this is done in a single dedicated thread, but we should not worry about multithreading issues because OpenAL functions are guaranteed to be thread-safe.

Getting ready

The source code and build scripts for the OpenAL library can be found in the 0_OpenAL folder, and precompiled static libraries are included with each of the examples for this chapter. For Windows, we use dynamic linking with OpenAL. Explanations on how to load files from the Android .apk package can be found in the Chapter 4, Organizing a Virtual Filesystem. The complete source of the example for this recipe can be found in the 0_AL_On_Android folder.
