The example game used in this book, Virgins Versus Vampires, was written using the Java programming language, which runs in the Dalvik virtual machine on Android devices. The game makes use of an open-source game engine called AndEngine and a physics engine called Box2D, both of which have been ported to Android. The game and all of its intellectual property were created using freely available software development tools, graphics tools, and audio. All of these items are described in this chapter, which also offers our first exposure to actually writing some code-specifically, a splash screen for the game.
