- 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.

- Startup (Utility)
AndroidX library to implement a straightforward, performant way to initialize components at app startup.
- AndroidX Test (Development Framework)
an extensive framework for testing Android apps.
- 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.

AndroidX library to display Views or Fragments in a swipeable format.
- 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.
- Jetpack WindowManager Library (Utility)
enables application developers to support new device form factors and multi-window environments. The library provides a common API surface for API versions 14 and later. Especially provides additional functionality on foldable devices.
- MPAndroidChart (Utility)
Android chart view / graph view library, supporting line- bar- pie- radar- bubble- and candlestick charts as well as scaling, dragging and animations.
- 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.
- Dagger (Utility)
A fast dependency injector for Android and Java.
- 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.
