CameraX

CameraX is a Jetpack support library, built to help you make camera app development easier. It provides a consistent and easy-to-use API surface that works across most Android devices, with backward-compatibility to Android 5.0 (API level 21).

- Ease of use
- Consistency across devices
- New camera experiences

While it leverages the capabilities of camera2, it uses a simpler, uses a case-based approach that is lifecycle-aware. It also resolves device compatibility issues for you so that you don't have to include device-specific code in your codebase. These features reduce the amount of code you need to write when adding camera capabilities to your app.

Lastly, CameraX enables developers to leverage the same camera experiences and features that preinstalled camera apps provide, with as little as two lines of code. CameraX Extensions are optional add-ons that enable you to add effects like Portrait, HDR, Night, and Beauty within your application on supported devices.
