[Bug] Failed to install apk UNAVAILABLE: io exception

[woen4]

This error happens when in a android emulator or in a android real device, I run the flow:

appId: com.woendev.fleet
---
- launchApp
- tapOn: "http://10.0.2.2:8082"

I'm using React native 0.70.5 with Expo SDK 47

Hi @woen4, thanks for submitting an issue!

We recently released a guide on how to work with Maestro and React Native -- you can find it here and hopefully you can get going with the help of the guide!

On another note, your tapOn command is invalid -- tapping on a URL is not supported. You can read more about the tapOn command and view usage examples here.

Please feel free to reopen if this issue persists after going through the guide!
