JetPack includes a number of components that can be used independently of one another, and cover four main concern areas: Foundation, Architecture, Behavior, and User Interface, as shown in the following image.Īlong with JetPack, Google published its own recommended Android app architecture, which defines what modules usually make an Android app and how they interact with each other. Second, it also provides higher-level abstractions on top of those found in the Android SDK, such as Fragments and Activities, in order to allow developers to express complex tasks in a simpler way. First, JetPack aims to leverage advanced Kotlin features in order to reduce boilerplate code programmers have to write. Two key ideas drove the design of JetPack towards that goal. When Google introduced JetPack, it set an ambitious goal for it: accelerating development of high-quality apps for the Android platform. Along with the Google JetPack collection of libraries, Dropbox Store provides a solution to create modern Android apps. Store has since been rewritten in Kotlin on the foundations provided by Coroutines and Flow. Originally developed at the New York Times, Store is a library for 'effortless, reactive data loading' that was originally written in Java.

Dropbox recently took ownership of the open-source Store library to revamp it and bring it closer to the current Android developer ecosystem.
