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.

a framework to define UIs programmatically with composable functions that describe its shape and data dependencies.

Firebase Data Transport is part of Google’s Firebase SDK.

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.

 

Firebase Installations is a service that allows you to manage the installation of your app on a user's device. The Firebase installations service (FIS) provides a Firebase installation ID (FID) for each installed instance of a Firebase app. Used e.g. for FCM, but also for Analytics.
