Classes

Name	Description
CameraAccessException	`CameraAccessException` is thrown if a camera device could not be queried or opened by the `CameraManager`, or if the connection to an opened `CameraDevice` is no longer valid.
CameraCaptureSession	A configured capture session for a `CameraDevice`, used for capturing images from the camera or reprocessing images captured from the camera in the same session previously.
CameraCaptureSession.CaptureCallback	A callback object for tracking the progress of a `CaptureRequest` submitted to the camera device.
CameraCaptureSession.StateCallback	A callback object for receiving updates about the state of a camera capture session.
CameraCharacteristics	The properties describing a `CameraDevice CameraDevice`.
CameraCharacteristics.Key	A `Key` is used to do camera characteristics field lookups with `CameraCharacteristics#get`.
CameraConstrainedHighSpeedCaptureSession	A constrained high speed capture session for a `CameraDevice`, used for capturing high speed images from the `CameraDevice` for high speed video recording use case.
CameraDevice	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.
CameraDevice.CameraDeviceSetup	CameraDeviceSetup is a limited representation of `CameraDevice` that can be used to query device specific information which would otherwise need a CameraDevice instance.
CameraDevice.StateCallback	A callback objects for receiving updates about the state of a camera device.
CameraExtensionCharacteristics	Allows clients to query availability and supported resolutions of camera extensions.
CameraExtensionSession	A camera capture session that enables access to device-specific camera extensions, which often use multi-frame bursts and sophisticated post-process algorithms for image capture.
CameraExtensionSession.ExtensionCaptureCallback	A callback object for tracking the progress of a `CaptureRequest` submitted to the camera device.
CameraExtensionSession.StateCallback	A callback object for receiving updates about the state of a camera extension session.
CameraExtensionSession.StillCaptureLatency	Realtime calculated still `#capture` latency.
CameraManager	A system service manager for detecting, characterizing, and connecting to `CameraDevice CameraDevices`.
CameraManager.AvailabilityCallback	A callback for camera devices becoming available or unavailable to open.
CameraManager.TorchCallback	A callback for camera flash torch modes becoming unavailable, disabled, or enabled.
CameraMetadata	The base class for camera controls and information.
CameraOfflineSession	A camera capture session that was switched to offline mode via successful call to `CameraCaptureSession#switchToOffline`.
CameraOfflineSession.CameraOfflineSessionCallback	Receives notifications about the state of an offline camera capture session.
CaptureFailure	A report of failed capture for a single image capture from the image sensor.
CaptureRequest	An immutable package of settings and outputs needed to capture a single image from the camera device.
CaptureRequest.Builder	A builder for capture requests.
CaptureRequest.InterfaceConsts	Contains constants from the Android interfaces implemented by CaptureRequest.
CaptureRequest.Key	A `Key` is used to do capture request field lookups with `CaptureRequest#get` or to set fields with `CaptureRequest.Builder#set(Key, Object)`.
CaptureResult	The subset of the results of a single image capture from the image sensor.
CaptureResult.Key	A `Key` is used to do capture result field lookups with `CaptureResult#get`.
DngCreator	The `DngCreator` class provides functions to write raw pixel data as a DNG file.
MultiResolutionImageReader	The MultiResolutionImageReader class wraps a group of `ImageReader ImageReaders` with the same format and different sizes, source camera Id, or camera sensor modes.
MultiResolutionImageReader.ActiveOutputSurfacesEventArgs	Provides the active output surfaces, timestamp, and frame number for a multi-resolution capture.
MultiResolutionImageReader.Builder	Builder class for `MultiResolutionImageReader` objects.
TotalCaptureResult	The total assembled results of a single image capture from the image sensor.

Interfaces

Name	Description
MultiResolutionImageReader.IOnActiveOutputSurfacesListener	Callback interface for being notified of the surfaces used for the capture.
