原因：尝试播放抽奖动画时

我遇到错误，原因是：尝试播放抽奖动画时出现java.io.FileNotFoundException：asset / loader.json。

正如您在我的布局xml中看到的那样，我将auto play设置为true，因此动画应在应用程序上播放。

但是我因上述错误而崩溃。

您可以在xml下面找到完整的日志。 如何解决？

顺便说一句，彩票的完整路径是：D：\ Project files \ MovieApp \ app \ src \ main \ assets \ loader.json。 在fileName属性中，我尝试设置不同的路径，但是对我来说没有任何作用。

这是我的splash_layout.xml 

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".view.activities.SplashActivity">

    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="wrap_content"
        android:id="@+id/lavLoader"
        app:lottie_autoPlay="true"
        app:lottie_loop="true"
        app:lottie_fileName="assets/loader.json"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

将app:lottie_fileName="assets/loader.json"替换为app:lottie_fileName="loader.json"。默认情况下，Lottie在src/main/assets文件夹中查找。
