使用React Native创建apk时遇到麻烦

我是新来的React Native，刚刚用React Native init rnapp命令创建了一个应用程序，它发出了许多警告：

然后我转到android文件夹并运行以下命令：

gradlew assemblerelease

但我明白了：

*

有人知道如何修复这个问题，并在这个空应用程序上为Android构建apk文件吗？

Answer 1

首先，您可以清理Gradle文件，然后使用此命令/gradlew AssemblereRelease。

Answer 2

这里有一个官方react本地网站的链接，展示了如何构建签名的android apk。

https://facebook.github.io/react-native/docs/signed-apk-android#__docusaurus

首先，您需要创建密钥库，下面是如何创建密钥库(https://stackoverflow.com/a/30254012/4829343)然后按照react native网站上的说明进行操作。
