 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.

 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.
