Camera2Interop.Extender

Camera2Interop.Extender

public Camera2Interop.Extender (ExtendableBuilder<T> baseBuilder)

Creates an Extender that can be used to add Camera2 options to another Builder.

setCaptureRequestOption

public Extender<T> setCaptureRequestOption (Key<ValueT> key, 
                ValueT value)

Sets a CaptureRequest.Key and Value on the configuration.

setDeviceStateCallback

public Extender<T> setDeviceStateCallback (CameraDevice.StateCallback stateCallback)

Sets a CameraDevice.StateCallback.

The caller is expected to use the CameraDevice instance accessed through the callback methods responsibly. Generally safe usages include: (1) querying the device for its id, (2) using the callbacks to determine what state the device is currently in. Generally unsafe usages include: (1) creating a new CameraCaptureSession, (2) creating a new CaptureRequest, (3) closing the device. When the caller uses the device beyond the safe usage limits, the usage may still work in conjunction with CameraX, but any strong guarantees provided by CameraX about the validity of the camera state become void.

setSessionCaptureCallback

public Extender<T> setSessionCaptureCallback (CameraCaptureSession.CaptureCallback captureCallback)

Sets a CameraCaptureSession.CaptureCallback.

The caller is expected to use the CameraCaptureSession instance accessed through the callback methods responsibly. Generally safe usages include: (1) querying the session for its properties. Generally unsafe usages include: (1) submitting a new CaptureRequest, (2) stopping an existing CaptureRequest, (3) closing the session, (4) attaching a new Surface to the session. When the caller uses the session beyond the safe usage limits, the usage may still work in conjunction with CameraX, but any strong guarantees provided by CameraX about the validity of the camera state become void.

The caller is generally free to use the CaptureRequest and CaptureResult instances accessed through the callback methods.

setSessionStateCallback

public Extender<T> setSessionStateCallback (CameraCaptureSession.StateCallback stateCallback)

Sets a CameraCaptureSession.StateCallback.

The caller is expected to use the CameraCaptureSession instance accessed through the callback methods responsibly. Generally safe usages include: (1) querying the session for its properties, (2) using the callbacks to determine what state the session is currently in. Generally unsafe usages include: (1) submitting a new CaptureRequest, (2) stopping an existing CaptureRequest, (3) closing the session, (4) attaching a new Surface to the session. When the caller uses the session beyond the safe usage limits, the usage may still work in conjunction with CameraX, but any strong guarantees provided by CameraX about the validity of the camera state become void.
