描述

Description

I'm not sure what's going on. I spent the afternoon trying to figure out how to run a new React Native project at version 0.78.0. I simply created a new project using the following command:

npx @react-native-community/cli@17.0.0 init AwesomeProject --version 0.78.0

The project was created, and I was able to build it successfully. However, as soon as I ran the Metro bundler, the app displayed a black screen. I had to manually close the app and reopen it for anything to appear.

Steps to reproduce
  1. First init a new project with npx @react-native-community/cli@17.0.0 init AwesomeProject --version 0.78.0
  2. Run npm run android && npm run start
  3. Await it to build, as soon as the app run close it, and open again manually.
React Native Version

0.78.0

调研方向

使用指定的 CLI 命令创建 React Native 0.78.0 来复现该问题,然后在报告中的 Android 环境上运行 npm run android  npm run start。首先跟踪 Metro bundler 的启动路径,并比较首次启动与重新打开应用的情况。当新构建的应用在首次启动时能够正常显示,且无需手动关闭并重新打开应用时,即表示完成。
