Mastering Android NDK

Overview of this book

Android NDK is used for multimedia applications that require direct access to system resources. NDK is also the key for portability, which in turn allows a reasonably comfortable development and debugging process using familiar tools such as GCC and Clang toolchains. This is a hands-on guide to extending your game development skills with Android NDK. The book takes you through many clear, step-by-step example applications to help you further explore the features of Android NDK and some popular C++ libraries and boost your productivity by debugging the development process. Through the course of this book, you will learn how to write portable multi-threaded native code, use HTTP networking in C++, play audio files, use OpenGL ES 3, and render high-quality text. Each chapter aims to take you one step closer to building your application. By the end of this book, you will be able to create an engaging, complete gaming application.

Dynamic linking on Windows platform


The libraries considered in this chapter can be built for Windows as dynamic link libraries. We do not provide recipes for doing this because each project already contains all the necessary instructions, and Windows development is not the focus of this book. The only exception is the libcurl and OpenSSL libraries. We recommend that you download the prebuilt DLL files from the official library site.

In the example code for FreeImage, FreeType, and Theora, we use function pointers, which are initialized using the GetProcAddress() and LoadLibrary() functions from WinAPI. The same function pointers are used on Android, but in this case, they point to appropriate functions from a static library.

For example, the function FreeImage_OpenMemory() is declared as follows:

typedef FIMEMORY* ( DLL_CALLCONV* PFNFreeImage_OpenMemory )
  ( void*, unsigned int );
PFNFreeImage_OpenMemory  FI_OpenMemory = nullptr;

On Windows, we initialize the pointer with the GetProcAddress...
