The next concept is Layouts. We will be dealing with Layouts in the next chapter but, just to give you a small introduction, let's provide a few examples. We will make a game, and in a game, we do not need to display the status bar, which means that we need to have a Fullscreen Layout. If you were making an app, then you probably would not mind allowing the status bar to be displayed on top. So, in this case, you can use a Relative Layout or Linear Layout. The really interesting aspect of this book is that, by the end, you will also have a basic idea of how to create a non-gaming app as well. So, it is highly recommended that you grasp the knowledge of the first three chapters properly.
