Project Explorer and project anatomy
When we create a new Android project, we most often do so with a project template, just as we did in Chapter 1, Getting Started with Android and Kotlin. The template that we use determines the exact selection and contents of the files that Android Studio will generate. While there are big similarities across all projects that are worth noting, seeing the differences can also help. Let's build two different template projects and examine the files, their contents, and how they are all linked together through the code (XML and Kotlin).
The Empty Activity project
The simplest project type with an autogenerated UI is the Empty Activity project. Here, the UI is empty, but it is ready to be added to. It is also possible to generate a project without a UI at all. When we create a project, even with an empty UI, Android Studio autogenerates the Kotlin code to display the UI. Therefore, when we add to it, it is ready to be displayed.
