新手用在 Android studio 使用 flutter 连接 virtual device 失败

我创建了一个 virtual device ，点击运行时提示

 Launching lib\main.dart on sdk gphone64 x86 64 in debug mode... Running Gradle task 'assembleDebug'...

但是我如果设备选择 chrome 就能运行。 找了一下资料，说要配置 flutter 的 Android SDK 目录。我也配置了。 系统是 windows10 ,Android studio 版本是 2022.2.1 Patch 2
