The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see Understanding the Android Support Library.

provides the base Activity subclass and the relevant hooks to build a composable structure on top.

library that contains the annotations for Android Jetpack.

helper for other arch dependencies, including JUnit test rules that can be used with LiveData.

improve autofill accuracy via extending hints.

standalone efficient collections.

a framework to define UIs programmatically with composable functions that describe its shape and data dependencies.

AndroidX library to help move tasks off the main thread with coroutines and take advantage of ListenableFuture.

a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.

a module to implement custom views. Part of the Android Support Library.

a library to view a file document.

create smooth animations with a physics-based animation API.

core library to enable emoji compatibility in Kitkat and newer devices to avoid the empty emoji characters.

leverages graphics facilities across multiple Android platform releases.

 

AndroidX library to use animation interpolators on older platforms.

a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.

perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.

library to load data for your UI that survives configuration changes.

an application-wide event bus and embraces layer violations in your app: any component may listen events from any other.

provides APIs to easily intercept platform navigation events, including swipes and clicks, to provide a consistent API surface for handling these events.

a library to print photos, docs, and other graphics and images.

AndroidX library that enables libraries to prepopulate ahead of time compilation traces to be read by ART.

a persistence library that provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.

provides the base Activity subclass and the relevant hooks to build a composable structure on top.

library that contains abstract interfaces along with basic implementations which can be used to build your own libraries that access SQLite.

AndroidX library to implement a straightforward, performant way to initialize components at app startup.

AndroidX library to write trace events to the system trace buffer.

animates motion in the UI with starting and ending layouts.

Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.

enables application developers to support new device form factors and multi-window environments. The library provides a common API surface for API versions 14 and later. Especially provides additional functionality on foldable devices.

Multiplatform color space conversions for Kotlin.

a component that provides two different HSV color pickers, written in Jetpack Compose.

a set of core libraries that includes new collection types (such as multimap and multiset), immutable collections, a graph library, functional types, an in-memory cache, and APIs/utilities for concurrency, I/O, hashing, primitives, reflection, string processing, and much more.

a static analysis tool for Java that catches common programming mistakes at compile-time.

A Java serialization/deserialization library to convert Java Objects into JSON and back.

OkHttp is an HTTP+HTTP/2 client for Android and Java applications.

library for handling IP addresses and subnets, both IPv4 and IPv6.

The Kotlin Programming Language

library support for Kotlin coroutines.

Kotlin cross-platform / multi-format serialization.

A modern I/O API for Java to make it much easier to access, store, and process your data.

development helper: integration for the IntelliJ IDEA IDE.

an artifact of fully-specified annotations to power static-analysis checks, beginning with nullness analysis.

abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing to plug in the desired logging framework at deployment time.

an implementation of DNS in Java. It supports all defined record types (including the DNSSEC types), and unknown types. It can be used for queries, zone transfers, and dynamic updates.
