  1. Foundation Components
  2. Architecture Components
  3. Behavior Components
  4. UI Components

  1.  Foundation Components - 

These are the main parts of foundation components.

  • Backward compatibility
  • Testing
  • Support for the Kotlin language.

App Compat: Material design user interface implementation support. 

Android KTX:  Kotlin extensions to write idiomatic, concise Kotlin code. 

Multidex: multiple dex files support for apps. 

Test: Testing framework for unit, runtime UI test.

  1.  Architecture Components - 

By using Architecture components we are building the following.

  • Robustable Apps
  • Testable Apps
  • Maintainable Apps

Following are the all architecture components.

  • Data Binding: Binding the UI elements to our layout for app data sources.
  • Lifecycles: It manages the activity and fragment of our app life cycles .
  • LiveData: It notifies us of the views of database changes.
  • Navigation: It handles everything for in-app navigation.
  • Paging: It loads the information on demand from your data source to your app.

  • Sharing: A share action which is suitable for the app's action bar.
  • Slices: It creates flexible UI elements which display app data outside the app.
  1.  UI Components - 

        These UI components provide widgets and helpers to make android apps that are easy and delightful to use.

Following are the all UI components.

  • Animation and transitions: It provides the moving widgets and transition between screens.
