The name of the Intent action used to launch a camera in still image mode for use when the device is secured (e.g. with a pin, password, pattern, or face unlock). Applications responding to this intent must not expose any personal content like existing photos or videos on the device. The applications should be careful not to share any photo or video with other applications or internet. The activity should use Android.Views.WindowManagerLayoutParams.FLAG_SHOW_WHEN_LOCKED to display on top of the lock screen while secured. There is no activity stack when this flag is used, so launching more than one activity is strongly discouraged.
