Emulator failed to boot

[AndyTWF]

When running the emulator on GitHub Actions (macos-latest), we occasionally get an error of Timeout waiting for emulator to boot. This is probably around 25-30% of test runs that we get this. I did a dive into the differences between a successful build and this error in terms of logs, but couldn't spot anything obvious.

The build logs are as follows:

Thanks! :)

Also running into the same since last 3 days.

+1 Also experiencing this for past 3 days. Seems to fail 70-80% of the time

[matt-ramotar]

Hey friends we are hitting this as well with Store

[Waltari10]

Same here. Running on 4-core latest ubuntu and it maybe starts 15% of time.

[mikus]

Same story, timeout in most cases:

777 /usr/local/lib/android/sdk/platform-tools/adb shell getprop sys.boot_completed
Terminate Emulator

780 OK: killing emulator, bye bye
781 OK
782 Error: Timeout waiting for emulator to boot.

[ipopov-belkacar]

API 29 with default config is working, but with API 30 I'm facing the same

782 Error: Timeout waiting for emulator to boot.

[josiasvfigueredo1985]

API 29 with default config is working, but with API 30 I'm facing the same

782 Error: Timeout waiting for emulator to boot.

I´m facing the same problem with that API, was everything fine until 2 day ago, and now that

[p709723778]

I have the same problem bytedance/flutter_ume#107

[matheusPereiraG]

It looks like the main workflow of this repo is also failing with the same problem we are all having :/ Is there any more information on what the problem is and when it will probably be fixed? Thank you in advance :)

[accounts01]

Same here for me. Has anyone made any headway?

[nihartsx]

has been happening for almost two months now. Are there any other alternate options that anyone is using with Github actions?

[accounts01]

I ended up firing up a Firebase Test Lab test from my Github Action. It's not as elegant as having everything running neatly in my own runner, but it'll do for now.
