AppCompat (Utility)
support newer Android features on older Android versions.
Jetpack Compose (Development Framework)
a framework to define UIs programmatically with composable functions that describe its shape and data dependencies.
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.
DataStore (Development Aid)
stores data asynchronously, consistently, and transactionally, overcoming some of the drawbacks of SharedPreferences.
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.
Glance (UI Component)
AndroidX library to build layouts for remote surfaces using a Jetpack Compose-style API.
Androidx Graphics (Utility)
leverages graphics facilities across multiple Android platform releases.
Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
ProfileInstaller (Utility)

Startup (Utility)
AndroidX library to implement a straightforward, performant way to initialize components at app startup.
Android Jetpack VersionedParcelable (Utility)
Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
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.
WorkManager (Utility)
an API that makes it easy to schedule deferrable, asynchronous tasks that must be run reliably .
Google Material Design (Utility)
library to help with material design guidelines.
Tink (Utility)
a multi-language, cross-platform library that provides cryptographic APIs that are secure, easy to use correctly, and hard(er) to misuse.
