In this chapter we revisited the AndroidSample project created earlier in the book and created a new version of the project structured to comply with the Android Jetpack architectural guidelines. The chapter outlined the structure of the Fragment + ViewModel project template and explained the concept of basing an app on a single Activity using Fragments to present different screens within a single Activity layout. The example project also demonstrated the use of ViewModels to separate data handling from user interface related code. Finally, the chapter showed how the ViewModel approach avoids some of the problems of handling Fragment and Activity lifecycles.
