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.

support newer Android features on older Android versions.

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

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.

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.

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

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.

share media contents and controls with other apps.

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.

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.

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 straightforward, performant way to initialize components at app startup.

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.

library that allows launching a custom activity when your app crashes, instead of showing the hated „Unfortunately, X has stopped“ dialog.

library to help with material design guidelines.
