GeoQuiz 3e -> 4K Changelog

Android Programming (4th Edition) General Book Discussion
1

I didn’t take a listing by listing set of notes for changes, but did note some high level feature differences:

Additions

  • Ch. 4 - QuizViewModel in addition to onSaveInstanceState()

Modifications

  • None

Deletions

  • None

Lingering Questions

  • In the context of the GeoQuiz, I’m unsure why the ViewModel is used and a Kotlin object declaration isn’t used in its place. My thought is the ViewModel was used to introduce the concept.
