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.

AndroidX library to inflate layouts asynchronously to avoid jank in the UI.

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.

AndroidX library to position top-level application widgets, such as AppBarLayout and FloatingActionButton.

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.

static library support version of the framework's CursorAdapter.

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

stores data asynchronously, consistently, and transactionally, overcoming some of the drawbacks of SharedPreferences.

a library to view a file document.

AndroidX library to implement a Material Design drawer widget.

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

a library to read and write image file EXIF tags.

AndroidX library to encapsulate part of the user interface or behavior into reusable components.

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.

a framework for navigating between 'destinations' within an Android application that provides a consistent API whether destinations are implemented as Fragments, Activities, or other components.

AndroidX library to make it easier to load data gradually and gracefully within an app's RecyclerView.

a library to build interactive settings screens without needing to interact with device storage or manage the UI.

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.

AndroidX library to surface the attributes of custom views in Android Studio’s Live Layout Inspector.

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

display large sets of data in your UI while minimizing memory usage.

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

AndroidX library to implement a sliding pane UI pattern.

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

AndroidX library to render vector graphics.

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

AndroidX library to display Views or Fragments in a swipeable format.

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.

an API that makes it easy to schedule deferrable, asynchronous tasks that must be run reliably .

an image loading library for Android backed by Kotlin Coroutines.

a collection of extension libraries for 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 Java serialization/deserialization library to convert Java Objects into JSON and back.

library that deals with Protocol Buffers (a.k.a., protobuf) – Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.

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