All future Jetpack libraries will be distributed under the AndroidX namespace. To use Jetpack Compose or cameras, for example, you must move to the AndroidX namespace.

2. Effortless App Structure

The Jetpack Navigation Component is required if you want to use Google’s suggested Single-Activity Architecture app strategy.

4. Efficient package management

AndroidX provides standardized and independent versioning, as well as improved name standards and more frequent releases. Other libraries, such as Google Play services, Firebase, Butterknife, Databinding Mockito, and SQL Delight, have transitioned to use the AndroidX namespace libraries.
