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.

support newer Android features on older Android versions.

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

AndroidX library to implement the Material Design card pattern with round corners and drop shadows.

standalone efficient collections.

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

library to reduce the number of nested views needed.

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.

a library to view a file document.

AndroidX library to implement a Material Design drawer widget.

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.

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

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.

share media contents and controls with other apps.

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

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

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.

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

implemtation of the swipe-to-refresh UI pattern.

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

animates motion in the UI with starting and ending layouts.

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.

replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.

library to help with material design guidelines.

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.

The Kotlin Programming Language

allows to obtain the same experience as with some of these libraries, without having to add any extra code or shipping any additional runtime.

library support for Kotlin coroutines.

Kotlin cross-platform / multi-format serialization.

Android optimized event bus that simplifies communication between Activities, Fragments, Threads, Services, etc.

development helper: integration for the IntelliJ IDEA IDE.

a Java library for working with real-world HTML. It provides an API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods.
