39. Modern Android App Architecture with Jetpack
Until recently, Google did not recommend a specific approach to building Android apps other than to provide tools and development kits while letting developers decide what worked best for a particular project or individual programming style. That changed in 2017 with the introduction of the Android Architecture Components which, in turn, became part of Android Jetpack when it was released in 2018.
The purpose of this chapter is to provide an overview of the concepts of Jetpack, Android app architecture recommendations and some of the key architecture components. Once the basics have been covered, these topics will be covered in more detail and demonstrated through practical examples in later chapters.
