Exploring Android is an integrated set of tutorials, guiding you step-by-step in building an Android application.
The current source code for this book can be found in this repository. That GitLab repository has the code for the second-generation Exploring Android, demonstrating Kotlin and the Jetpack.
The repository that you are viewing is for the first-generation Exploring Android, demonstrating Java.

Each directory in this repository reflects the "answers" to having completed
the tutorials to a certain point. So, for example, the T14-RecyclerView/
directory contains a copy of the app being built, after having completed the
14th tutorial ("Populating Our RecyclerView"). If you wish to import
the results of one of the tutorials into Android Studio, you want to import
the ToDo/ directory inside of one of the top-level directories. In other
words, import T14-RecyclerView/ToDo/, not T14-RecyclerView/.
Remember,
always check the gradle-wrapper.properties file before importing anything into Android Studio,
as there is always the chance that somebody has published material linking you to a hacked Gradle installation.
