Jetpack is a suite of libraries to help developers follow best practices, reduce boilerplate code, and write code that works consistently across Android versions and devices so that developers can focus on the code they care about.
Jetpack Compose
A modern toolkit for building native UI that enables you to simplify and accelerate UI development on Android.

Why use Android Jetpack?

Built around modern design practices, Android Jetpack Libraries enable fewer crashes and less memory leaks with backwards-compatibility baked in.
Android Jetpack manages tedious activities like background tasks, navigation, and lifecycle management, so you can focus on what makes your app great.
Reduce complexity with libraries that work consistently across Android versions and devices.

* Popular and often-used libraries are listed first

activity * Access composable APIs built on top of Activity.
appcompat * Allows access to new APIs on older API versions of the platform (many using Material Design).
appsearch * Build custom in-app search capabilities for your users.
camera * Build mobile camera apps.
compose * Define your UI programmatically with composable functions that describe its shape and data dependencies.
databinding * Bind UI components in your layouts to data sources in your app using a declarative format.
fragment * Segment your app into multiple, independent screens that are hosted within an Activity.
hilt * Extend the functionality of Dagger Hilt to enable dependency injection of certain classes from the androidx libraries.
lifecycle * Build lifecycle-aware components that can adjust behavior based on the current lifecycle state of an activity or fragment.
Material Design Components * Modular and customizable Material Design UI components for Android.
navigation * Build and structure your in-app UI, handle deep links, and navigate between screens.
paging * Load data in pages, and present it in a RecyclerView.
room * Create, store, and manage persistent data backed by a SQLite database.

Compose August 2023
Jetpack Compose 1.5.0 moves to stable and brings major performance improvements including a refactoring of high-level modifiers such as `Clickable` that can improve composition time by 80%. August‘23 Compose also brings up to 70% improvement in memory allocation (especially in the graphics stack), which will reduce the memory footprint of compose on devices
Wear Compose and Tiles 1.2
Both Wear Compose and Wear Tiles have moved to stable to further enhance the experience of wearOS developers. Both are complementary to each other where Wear Compose can be used to build complex app screens on wear devices, and wear tiles can be used to create the app tiles. The new Wear Compose release contains new functionalities such as Expandable Items and Swipe to reveal. Wear Tiles release also now supports widget animation, and platform data binding (such as health data source).
Window 1.1
1.1 stabilizes activity embedding APIs, allowing apps like WhatsApp, eBay and Temu to ship large screen layouts. The API is enriched with features, as it enables developers to modify split screen behavior, check (and change) split state at runtime, implement horizontal splits, and start a modal in full window.
