无法使行为子类com.luseen.spacenavigation.SpaceNavigationViewBehavior膨胀

Question

在我的应用程序中，我已将此库https://github.com/armcha/Space-Navigation-View包含在底部导航中，并添加了回收器视图滚动行为

<com.luseen.spacenavigation.SpaceNavigationView
        android:id="@+id/space"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        app:space_background_color="@color/colorPrimary"
        app:active_item_color="@color/colorTextPrimary"
        app:inactive_item_color="@color/colorWhite"
        app:centre_button_color="@color/colorAccent"
        app:centre_button_icon="@drawable/ic_camera_white_24dp"
        app:inactive_centre_button_icon_color="@color/colorWhite"
     app:layout_behavior="com.luseen.spacenavigation.SpaceNavigationViewBehavior" />

我在gradle文件中有mutidexenabled。没有为库添加progaurd规则。他们没有提到要包含的内容。现在这在调试模式下运行良好。在发布模式下，此操作失败并出现以下错

我有解决方案： -

        }
    }
