android - 无法将 Android 模拟器连接到 React Native 调试器

Question

我无法将 android 模拟器与 react native 调试器连接起来。

当我运行 react-native run-android ，它会成功启动应用程序而不会显示任何错误。它还带来了节点 Metro Bundler。但它没有在 RN 调试器中打印任何日志。当我在页面上按 Reload app 时，它显示以下弹出错误:

React Native: No apps connected
Sending 'reload' to all React Native apps failed. Make sure your app is running in the simulator or on a phone

Popup error when press on RN debugger "Reload app" button

我试过运行这个 adb reverse tcp:8081 tcp:8081但它不起作用。当我在模拟器中按 Cmd+m 时，它显示多点触控。所以我也无法打开开发者菜单。

Answer 1

模拟器是指真机还是安卓工作室？

如果您尝试从 android studio 连接模拟器，请卸载设备并安装 Pixel 2，它可能会对您有所帮助。

并卸载 React native 调试器并安装最新的
