Chapter 2. Kotlin, XML, and the UI Designer
At this stage, we have a working Android development environment and we have built and deployed our first app. It is obvious, however, that code autogenerated by Android Studio is not going to make the next top-selling app on Google Play. We need to explore this autogenerated code so that we can begin to understand Android and then learn how to build on this useful template. With this aim in mind, we will do the following in this chapter:

- Examine the Kotlin code and User Interface (UI) XML code from our first app.
- Get our first taste of using the Android UI designer.
- Write our first Kotlin code.
- Learn some core Kotlin fundamentals and how they relate to Android.
