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.

display webpages in the user's default browser.

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 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.

library to help building dialogs that meet the Material Design standards, including e.g. progress display, multiple-choice selections with check-boxes, password (and other) text input.

logging helper: SLF4J binding for Jake Wharton's Timber logging library.

a fast and compliant streaming JSON parser/writer with a StAX-like API and support for marshalling/unmarshalling POJOs via annotations.

simple OAuth library.

Firebase Data Transport is part of Google’s Firebase SDK.

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 collection of source code generators for Java.

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.

 

library to parse JSON into Java objects.

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

A fast dependency injector for Android and Java.

specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

The Kotlin Programming Language

library support for Kotlin coroutines.

core library for Android „Locus Map“ application.

A modern I/O API for Java to make it much easier to access, store, and process your data.

development helper: integration for the IntelliJ IDEA IDE.

a small library to lets you write dependency injection in a concise and pragmatic way.

collection of various android-related utilities.

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

Type-safe HTTP client for Android and Java by Square, Inc.

logger with a small, extensible API which provides utility on top of Android's normal Log class.
