好吧，我在React Native expo中使用Lottie，并使用Bodymovin插件将我在AfterEffects中制作的动画导出为json。我import LottieView from 'lottie-react-native'，它们在iOS上运行良好。
问题是，我在安卓系统上运行时出现此错误https://github.com/react-native-community/lottie-react-native/issues/473
这个答案表明问题是Lottie的新版本，所以我在Lottie网站上找到了旧的动画，它们在Android上没有问题。所以我进入Bodymovin高级设置并勾选"；"遗留"；框中，然后导出。但我的动画仍然在安卓系统上崩溃。
我的动画出了什么问题？
编辑这是json:

所以，我试过你的彩票文件，结果她是空的。
在我的项目中，每个彩票都做得很好，所以我想你的项目的解决方案是：
在package.json上，将lottie-react-native版本替换为^3.3.2然后，在项目根文件夹上使用终端，运行：rm -rf node_modules && npm install --save(如果使用yarn而不是npm，则运行yarn install(
然后，使用任何可以在lottiefiles 上下载为json的文件替换您的lottie文件
这应该工作
