| * |
| * <p>PermissionsUtil.registerPermissionReceiver(getActivity(), receiver, READ_CONTACTS); |

| * <p>If you register to listen for multiple permissions, you can identify which permission was |
| * granted by inspecting {@link Intent#getAction()}. |
| * |
| * <p>In the fragment that requests for the permission, be sure to call {@link |
| * #notifyPermissionGranted(Context, String)} when the permission is granted so that any |
| * interested listeners are notified of the change. |
