Com.android.camera2

The com.android.camera2 package provides a set of classes and interfaces that enable developers to access and control the device’s camera hardware. The API is designed to replace the older Camera API, which was limited in its capabilities and flexibility.

The com.android.camera2 package is a part of the Android operating system, providing a powerful API for developers to interact with the device’s camera hardware. Introduced in Android 5.0 (Lollipop), the Camera2 API offers a more comprehensive and flexible way to control camera functionality, allowing developers to create more sophisticated camera-based applications. hardware
