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.

Flurry analytics


Let's touch one more Java-related thing and its binding to the native C++ code. Flurry.com is a popular in-app analytics service. Determination of the most used features in your app is accomplished by sending information to Flurry.com and later accessing gathered statistics on their web pages.

For example, you have several options in your application such as the different game modes: campaign, single level, or online. User selects one of the modes and an event is generated and sent to Flurry.com. We want to send those events from our C++ code.

Check out the sample application in the 5_Flurry folder. The main.cpp file contains a typical usage example:

  void OnStart()
  {
    TrackEvent( "FlurryTestEvent" );
  }

The definition of TrackEvent() and the difference between Android and desktop implementations is located in the Callbacks.cpp file:

  extern "C"
  {
    void Android_TrackEvent( const char* EventID );
  };
  void TrackEvent( const char* EventID )
  {
    #if defined(ANDROID...
