- 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. 
- Arch (Utility)   helper for other arch dependencies, including JUnit test rules that can be used with LiveData. 
- Android Support Library collections (Utility)   standalone efficient collections. 
- Jetpack Compose (Development Framework)   a framework to define UIs programmatically with composable functions that describe its shape and data dependencies. 
- Concurrent (Utility)   AndroidX library to help move tasks off the main thread with coroutines and take advantage of ListenableFuture. 
- 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.

- Lifecycle (Utility)   perform actions in response to a change in the lifecycle status of another component, such as activities and fragments. 
- Navigation (Utility)   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. 
- ProfileInstaller (Utility)   AndroidX library that enables libraries to prepopulate ahead of time compilation traces to be read by ART. 
- Room (Utility)   a persistence library that provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite. 
- Android Activity Saved State (Utility)   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. 
- 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. 
- Android Jetpack VersionedParcelable (Utility)   Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely. 
- Accompanist (Utility)   a collection of extension libraries for Jetpack Compose. 
- MMKV (Utility)   small mobile key-value storage framework developed by WeChat. 
- Dagger (Utility)   A fast dependency injector for Android and Java. 
- Kotlin (Utility)   The Kotlin Programming Language 
- kotlinx.coroutines (Utility)   library support for Kotlin coroutines. 
- Kotlin serialization (Utility)   Kotlin cross-platform / multi-format serialization.
