The CameraDevice class is a representation of a single camera connected to an Android device, allowing for fine-grain control of image capture and post-processing at high frame rates.

Remarks
The CameraDevice class is a representation of a single camera connected to an Android device, allowing for fine-grain control of image capture and post-processing at high frame rates.
Your application must declare the android.Manifest.permission#CAMERA Camera permission in its manifest in order to access camera devices.
A given camera device may provide support at one of several levels defined in CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL. If a device supports CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY LEGACY level, the camera device is running in backward compatibility mode and has minimum camera2 API support. If a device supports the CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED LIMITED level, then Camera2 exposes a feature set that is roughly equivalent to the older android.hardware.Camera Camera API, although with a cleaner and more efficient interface. If a device supports the CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_EXTERNAL EXTERNAL level, then the device is a removable camera that provides similar but slightly less features as the CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED LIMITED level. Devices that implement the CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_FULL FULL or CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_3 LEVEL3 level of support provide substantially improved capabilities over the older camera API. If your application requires a full-level device for proper operation, declare the "android.hardware.camera.level.full" feature in your manifest.
