+ * <p>Specifically, this class is responsible for:
+ * <ul>
+ * <li>Adjusting the scheduling of VR render threads while in VR mode.
+ * <li>Handling ActivityManager calls to set a VR or a 'persistent' VR thread.
+ * <li>Tracking the state of ActivityManagerService's view of VR-related behavior flags.
+ * </ul>
+ *
+ * <p>This is NOT the class that manages the system VR mode lifecycle. The class responsible for
+ * handling everything related to VR mode state changes (e.g. the lifecycles of the associated
+ * VrListenerService, VrStateCallbacks, VR HAL etc.) is VrManagerService.
+ *
+ * <p>This class is exclusively for use by ActivityManagerService. Do not add callbacks or other
+ * functionality to this for things that belong in VrManagerService.
