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.
- 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.

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.
- Sqlite (Utility)
library that contains abstract interfaces along with basic implementations which can be used to build your own libraries that access SQLite.
- 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.
- WorkManager (Utility)
an API that makes it easy to schedule deferrable, asynchronous tasks that must be run reliably .
- FasterXML Jackson (Utility)
a fast and compliant streaming JSON parser/writer with a StAX-like API and support for marshalling/unmarshalling POJOs via annotations.
- jackson-coreutils (Utility)

a fully functional Java implementation of URI templates (RFC 6570): create URIs for your REST API without room for errors.
- Google Play OSS-Licenses (UI Component)
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© (Development Framework)
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.
- 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.
- Error Prone (Utility)
a static analysis tool for Java that catches common programming mistakes at compile-time.
- Google Gson (Utility)
A Java serialization/deserialization library to convert Java Objects into JSON and back.
- libphonenumber (Utility)
library for parsing, formatting, and validating international phone numbers.
- J2ObjC (Utility)
Java to Objective-C Translator and Runtime.

Barcode scanning library for Android, using ZXing for decoding.
- OkHttp (Utility)
OkHttp is an HTTP+HTTP/2 client for Android and Java applications.
- Sun Mail (Utility)
part of the JavaMail™ API provides classes that model a mail system.

- JavaX Dependency Injection (Utility)
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.
