Introducing Jetpack
This book is titled “Elements of Android Jetpack”. Yet, we have not yet discussed Jetpack at all. So, it’s about time that we saw what Jetpack is and what it has to do with Android app development, your future projects, and the rest of this book.
What, Exactly, is Jetpack?
Jetpack… is a brand name.
In 2018, Google elected to use the term “Jetpack” to refer to a seemingly-random collection of Android technologies and tools. In many respects, the only things that those technologies and tools have in common is:
- They are involved in Android app development
- Google thinks that they are part of Jetpack
There is no singular “Jetpack” tool or library. In fact, outside of the cover and the contents of this chapter, “Jetpack” will not be used much as a term in this book, as it focuses on what is in Jetpack more so than Jetpack itself.
