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.

standalone efficient collections.

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.

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.

 

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.

helps deploying applications with multiple dex files on pre-Android 5 devices.

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 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 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.

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 .

API to automatically handle access to Google Maps servers, data downloading, map display, and response to map gestures.

give an indication that the device is currently located at a particular Place.

Google Mobile Services in terms of the Android library refers to Google Play Services, a proprietary background service and API package for Android devices which is not part of the Android Open Source Project (AOSP). The library does not contain those services (i.e. it usually requires the Google Framework, often referred to as „GApps“, being installed on the device), but allows an app to communicate with them. Be aware this usually goes along with transferring at least parts of your personal data to the Google network.

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.

Java to Objective-C Translator and Runtime.

repackaged upstream version of HttpClient and depdendencies.

library using static analysis to look for bugs in Java code.

common annotations for the JavaTM Platform API.

The Kotlin Programming Language

library support for Kotlin coroutines.

a cleanroom implementation of the JCIP (Java Concurrency in Practice) annotations.

pluggable type-checking to detect and prevent errors in their Java programs.

build signatures of APIs and to check your classes against previously generated signatures.

development helper: integration for the IntelliJ IDEA IDE.

a geodetic library with basic representations for Latitude, Longitude, MGRS, Universal Transverse Mercator (UTM), 2-D and 3-D bounding boxes, etc.

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