如何解决 Android Studio 中的 Lottie 动画错误

Question

Gradle 文件

implementation "com.airbnb.android:lottie:6.4.0"

布局代码

<com.airbnb.lottie.LottieAnimationView
  android:id="@+id/flightAnimation"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:layout_gravity="center"
  android:layerType="hardware"
  android:paddingTop="5dp"
  android:visibility="visible"
  app:lottie_autoPlay="true"
  app:lottie_loop="true"
  app:lottie_rawRes="@raw/coffee_anim" />

原图

当我运行我的应用程序时

当我打开应用程序时，有时它会崩溃，有时动画会变得受宠若惊。应用程序崩溃，错误显示未跟踪版本。请让我知道问题是什么。我想知道是否有任何特定版本的lottie动画问题或其他问题。

logcat 出错

Answer 1

您的 json 文件似乎有问题：

尝试用 this json 代替 Coffee_anim。

输出：

<div style="position: relative; padding-bottom: 56.25%; height: 0;"><iframe src="https://jumpshare.com/embed/njrpEifqrLbuwPc6BrR7" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen style="position: absolute; top: 0; left: 0; width: 100%; height: 100%;"></iframe></div>
