关于 setImageAssetsFolder("sucess/images");报错的问题

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.airbnb.lottie.LottieAnimationView.setImageAssetsFolder(java.lang.String)' on a null object reference
    at com.example.myapplication4.BlankFragmentgame1.onActivityCreated(BlankFragmentgame1.java:45)只知道是空指针异常，请大佬帮帮忙

你的lettie是空的
你先确认一下该组件是否真实存在吧
