Question

我是React-native的新手，并使用“ react-native init myApp”和“ react-native run-android”运行了我的第一个应用程序。但是，当我尝试安装第三方库（react-native-track-player）时，出现以下错误。我已经在这个问题上待了几天，并且尝试了许多其他建议的解决方案，例如运行'./gradlew clean build'，'删除app / build并再次运行它'，'更改构建工具版本以匹配android studio版本”，但这些都不能解决问题。提前非常感谢您的帮助。

Execution failed for task ':app:transformClassesWithDexBuilderForDebug

然后在添加这两行之后，按照文档https://developer.android.com/studio/build/multidex启用multidex ..

multiDexEnabled true
compile 'com.android.support:multidex:1.0.3'

我仍然遇到相同的错误。在文档中，它说明了有关覆盖应用程序类的内容，我不确定这意味着什么。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithDexBuilderForDebug'.
