Understanding the Android Support Library.
- AndroidX Activity (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
- Android Jetpack Annotations (Utility)
library that contains the annotations for Android Jetpack.

helper for other arch dependencies, including JUnit test rules that can be used with LiveData.
- AppCompat (Utility)
support newer Android features on older Android versions.
- Cardview (UI Component)
AndroidX library to implement the Material Design card pattern with round corners and drop shadows.
- Android Support Library collections (Utility)
standalone efficient collections.
- Concurrent (Utility)
AndroidX library to help move tasks off the main thread with coroutines and take advantage of ListenableFuture.
- Constraint Layout Library (Utility)
library to reduce the number of nested views needed.
- Coordinatorlayout (UI Component)
AndroidX library to position top-level application widgets, such as AppBarLayout and FloatingActionButton.
- Androidx Core (Utility)
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.
- Android Support Library Custom View (UI Component)
a module to implement custom views. Part of the Android Support Library.
- Android Emoji2 Compat (UI Component)
core library to enable emoji compatibility in Kitkat and newer devices to avoid the empty emoji characters.
- AndroidX Fragment (UI Component)
AndroidX library to encapsulate part of the user interface or behavior into reusable components.
- Interpolator (UI Component)
AndroidX library to use animation interpolators on older platforms.
- Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
- Loader (Utility)
library to load data for your UI that survives configuration changes.
- AndroidX Local Broadcast Manager (Utility)
an application-wide event bus and embraces layer violations in your app: any component may listen events from any other.
- Preference (Utility)
a library to build interactive settings screens without needing to interact with device storage or manage the UI.
- ProfileInstaller (Utility)
AndroidX library that enables libraries to prepopulate ahead of time compilation traces to be read by ART.
- Recyclerview (Utility)
display large sets of data in your UI while minimizing memory usage.
- Android Activity Saved State (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
- Startup (Utility)
AndroidX library to implement a straightforward, performant way to initialize components at app startup.
- Tracing (Utility)
AndroidX library to write trace events to the system trace buffer.
- Transition (UI Component)
animates motion in the UI with starting and ending layouts.
- Vectordrawable (UI Component)
AndroidX library to render vector graphics.
- Android Jetpack VersionedParcelable (Utility)
Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
- AndroidX Widget ViewPager2 (UI Component)
replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.
- Logback (Utility)
a logging helper intended as a successor to the popular log4j project, picking up where log4j leaves off.
- Google Material Design (Utility)
library to help with material design guidelines.
- Google Core Libraries for Java 6+ (Utility)
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.
- Google Gson (Utility)
A Java serialization/deserialization library to convert Java Objects into JSON and back.
- Google Protocol Buffers (Utility)
library that deals with Protocol Buffers (a.k.a., protobuf) – Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data.
- ZXing ('Zebra Crossing') (Utility)
ZXing („zebra crossing“) is an open-source, multi-format 1D/2D barcode image processing library.
- gRPC-Java (Utility)
RPC library and framework.
- Netty Project (Development Framework)
an event-driven asynchronous network application framework.
- PerfMark (Utility)
a low-overhead, manually-instrumented, tracing library.
- jmDNS library (Utility)
an implemenation of multi-cast DNS in Java, fully interoperable with Apple's Bonjour.
- Kotlin (Utility)
The Kotlin Programming Language
- kotlinx.coroutines (Utility)
library support for Kotlin coroutines.
- OkHttp okio Framework (Utility)
A modern I/O API for Java to make it much easier to access, store, and process your data.
- Bouncy Castle (Utility)
a collection of APIs used in cryptography. Also see
Wikipedia.
- Conscrypt (Utility)
a Java Security Provider (JSP) that implements parts of the Java Cryptography Extension (JCE) and Java Secure Socket Extension (JSSE). It uses BoringSSL to provide cryptographic primitives and Transport Layer Security (TLS) for Java applications on Android and OpenJDK.
- OpenJAX Security NaCl (Utility)
easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc.
- Simple Logging Facade for Java (Utility)
abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing to plug in the desired logging framework at deployment time.
