- Android Support v4 (Development Framework)
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see
Understanding the Android Support Library.
- AndroidX Activity (Utility)

- 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.
- 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.
- AndroidX Fragment (UI Component)
AndroidX library to encapsulate part of the user interface or behavior into reusable components.
- Lifecycle (Utility)

- Android Activity Saved State (Utility)

- Viewpager (UI Component)
AndroidX library to display Views or Fragments in a swipeable format.
- AndroidX Widget ViewPager2 (UI Component)

- 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 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 Gson (Utility)
A Java serialization/deserialization library to convert Java Objects into JSON and back.
- Calligraphy (UI Component)
