No Android connected device found, and no emulators could be started automatically. Please connect a device or create an emulator (https://docs.expo.dev/workflow/android-studio-emulator). Then follow the instructions here to enable USB debugging: https://developer.android.com/studio/run/device.html#developer-device-options. If you are using Genymotion go to Settings -> ADB, select "Use custom Android SDK tools", and point it at your Android SDK directory.

똑같은 오류 찾음!!

https://github.com/expo/expo/issues/15183

Gradle build fail on first time doing expo run:android · Issue #15183 · expo/expo

여기에 있는대로 시키는대로 똑같이 하니까 에뮬레이터 키는거 까진 성공
