This may seem overwhelming at first, but as the book goes on, things will make more and more sense. I recommend checking out the source code I’ll mention in the next section to see how things fit together. With Android apps, a high-level overview is that your UI (what the user sees) is mostly handled within XML, while the logic is handled with the Kotlin code.

Speaking of Kotlin, you’ll find a number of mentions to Java in the book. Now, we are not going to be writing any Java code in the book, but we will be interacting with it, as most Android libraries were written in Java. Therefore, our Kotlin setup includes associating with a Java version, and we even use a directory called java for our Kotlin code. This is all because both Java and Kotlin compile down to the same byte code, so we can use them interchangeably. Just try to not be thrown off when you see Java mentioned, because it doesn’t mean you need to start writing Java code or anything.
