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.

In the previous chapter, we built the libcurl library. As a refresher on how to download a web page, refer to the 1_CurlDownloader example in the accompanying materials for this chapter.

The information about using Picasa and Flickr in C++ is somewhat limited, but calling the REST (Representational State Transfer) APIs of these sites is no different from downloading web pages. All we have to do is form a correct URL for the images list, download an XML file from this URL, and then parse this file to build a list of individual image URLs. Usually, REST APIs require some form of authentication using oAuth, but for the read-only access, it is sufficient to use only the application key, which is available through the simple online registration.

Note

The example code in this recipe only forms the URLs and it is up to the reader to download the actual image list. We also do not provide an application key here, and we encourage the reader to obtain a...
