Summary
In this chapter, we achieved quite a bit. We saw and edited our layout XML file using both the UI designer, as well as through tinkering with the raw code. We took a glimpse at our first Java code and even added our own methods in order to output debugging messages to the console, and pop-up Toast messages to the user.
In the next chapter, we will take a complete guided tour of Android Studio to see exactly where different things get done at the same time, to understand how our projects assets, such as files and folders, are structured, and to learn how to manage them. This will prepare us to take a more in-depth look at the UI design in Chapter 4, Designing Layouts and Chapter 5, Real-World Layouts, and build some significant real-world layouts for our apps.
