The emulator would not complete the boot sequence for me on ubuntu, it just forever hanged, and I had to use a macos agent for android.

The docs also state:

Note: The Android Emulator is currently available only on the Hosted macOS agent.

You are a god among men, worked on macOs-latest out of the box with minor tweaks.

@badsyntax you're right, it doesn't work on non macos agents.. I recall myself trying the android/ubuntu-latest one only to find out it doesn't support emulator... so I switched to macos one

Now I would consider trying the official docker image for RN in the android one (I don't recall how to use azure devops in depth anymore so I won't be updating this gists XD)

@asenmitrev
thank you, I'm really glad I can help other devs ❤️

Could you share which parameters are you passing to avdmanager and emulator tools? In my case, it gets stuck on adb wait-for-device

I am using macOs-latest image

@tomasfly I'm sorry, I'm not using azure since some months after posting this

You can however try to boot the emulator without the nohup part and look at the logs
