Chapter 12 ends with the following paragraph:
“In the next chapter, you will learn how to further improve your code by integrating the Data Binding library to bind your UI components in your layouts to your data sources.”
However, the upcoming chapter is Chapter 13: MVVM Testing. I believe this is meant to refer to the previous chapter, Chapter 11: MVVM Sample with Data Binding. I assume the chapters were likely moved around at some point. Just wanted to make sure you guys were aware.
Solid book so far!
