We learned a lot in this chapter about Libgdx and how all the projects of an application work together. We covered Libgdx's backends, modules, and Starter Classes. Additionally, we covered what the Application Life-Cycle and corresponding interface are and how they are meant to work. The debugger has been used to inspect the demo application at runtime, and furthermore we made use of the JVM Code Hot Swapping feature.
We now know the basics of the Libgdx applications, so now we are ready to start developing a real game. We will start at the very beginning of the development cycle step-by-step. Since Libgdx is a framework but not a game engine, we first have to build our own engine. So, we will learn how to create an appropriate program architecture that is suitable to handle our game in the next chapter.
