CameraConfig.FacingDirection


          public static final   enum
          CameraConfig.FacingDirection

Describes the direction a camera looks relative to the device. Used by CameraConfig.getFacingDirection().

public static final CameraConfig.FacingDirection BACK

Back-facing (world) camera (away from the user).

When used as a camera filter, via CameraConfigFilter.setFacingDirection(CameraConfig.FacingDirection), filters for camera configs that use a back-facing (world) camera.

public static final CameraConfig.FacingDirection FRONT

Front-facing (selfie) camera (toward the user).

See ARCore supported devices for available camera configs by device.

To limit distribution of your app to only devices that have a front-facing camera, use uses-feature with android.hardware.camera.

When used as a camera filter, via CameraConfigFilter.setFacingDirection(CameraConfig.FacingDirection), filters for camera configs that use a front-facing (selfie) camera.

To create a session using the front-facing (selfie) camera, use Session.setCameraConfig(CameraConfig) to set a front-facing (selfie) camera config retrieved from Session.getSupportedCameraConfigs(CameraConfigFilter).

When the front camera is selected, ARCore's behavior changes in the following ways:

The display will be mirrored. Specifically, Camera.getProjectionMatrix(float[], int, float, float) will include a horizontal flip in the generated projection matrix and APIs that reason about things in screen space such as Frame.transformCoordinates2d(Coordinates2d, float[], Coordinates2d, float[]) will mirror screen coordinates. Open GL apps should consider using glFrontFace to render mirrored assets without changing their winding direction.
Camera.getTrackingState() will always return TrackingState.PAUSED.
All forms of Frame.hitTest() will always return an empty list.
Camera.getDisplayOrientedPose() will always return an identity pose.
Session.createAnchor(Pose) will always throw NotTrackingException.
Planes will never be detected.
Session.configure(Config) will throw if the supplied configuration requests Cloud Anchors or Augmented Images.
