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.

standalone efficient collections.

library to reduce the number of nested views needed.

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 library to view a file document.

 

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.

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.

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

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.

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

scans the AAR and JAR dependencies in the project at compile time and provides a list of found licenses to present to the user.

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.

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.

The Kotlin Programming Language

library support for Kotlin coroutines.
