我正在尝试在React Native中实现lottie框架。它在iOS中完美运行。当我尝试在Android中运行该应用程序并收到以下错误。我不知道是什么问题以及它来自何处。我在互联网上搜索过,但我无法找到解决方案。

我有同样的问题。 link命令不能完全正常工作。您需要手动链接库。如果您不知道如何执行此操作,请发布build.gradle和settings.gradle。
看到gradle文件后编辑:
在这里你有两次lottie:
dependencies {
...
compile project(':lottie-react-native')
...
compile 'com.airbnb.android:lottie:2.2.5'
}
第二个是文档中推荐的那个,但对我来说不起作用,我假设一个新的RN版本。第一个是链接命令添加的那个,应该可以工作。尝试评论第二次编译,看看是否完成了构建。
