Android Vuforia Native SDK camera direction Front

Unable to change camera direction using Vuforia Native SDK.

I am changing 

vuforiaAppSession.startAR(CameraDevice.CAMERA_DIRECTION.CAMERA_DIRECTION_DEFAULT);

at ImageTargets.java inside Vuforia sample app. The result I am getting with front camera is just black screen.

Here is the error code: 

VuforiaSamples E/ImageTargets: Unable to open camera device: 2
    com.vuforia.samples.SampleApplication.SampleApplicationException: Unable to open camera device: 2
        at com.vuforia.samples.SampleApplication.SampleApplicationSession.startCameraAndTrackers(SampleApplicationSession.java:153)

Not able to find some more specific information.

From what I see, Vuforia has deprecated this option.

See CameraDevice.CAMERA_DIRECTION Class Reference. Same for C++ headers:

enum CAMERA_DIRECTION
{ 
    CAMERA_DIRECTION_DEFAULT,   ///< Default camera direction (device-specific,
                                ///  usually maps to back camera) (DEPRECATED)
    CAMERA_DIRECTION_BACK,      ///< The camera is facing in the opposite direction as the screen (DEPRECATED)
    CAMERA_DIRECTION_FRONT,     ///< The camera is facing in the same direction as the screen. (DEPRECATED)
                                ///< Notes: This enum is deprecated.
                                ///< Front camera support will be removed in a future Vuforia release.
                                ///< The front camera is not compatible with DeviceTracker
                                ///< nor with SmartTerrain.
};
