error: device offline

Hi,

i just found your GitHub action and wanted to use it for instrumented tests.

Unfortunately i don't get it working. Every run ends in an endless-loop, like this:

You can find my configuration here: https://github.com/stefan-niedermann/nextcloud-deck/blob/instrumented-tests-ci/.github/workflows/android.yml#L25-L39 and the full log output here: https://github.com/stefan-niedermann/nextcloud-deck/runs/597664917 (raw)

Do you have any clue what i am doing wrong?

Thank you in advance

[stefan-niedermann]

I just switched to api-level: 27 after reading #45 and i don't get the error: device offline error any more. Maybe i just haven't been patient enough.

I will try it further and close this issue when i get one successful build :)

Hi. It's not an endless loop, just the emulator being incredibly slow without hardware acceleration especially on the later API levels. Please read this issue for why Linux VMs are expected to be slow and that you probably shouldn't run the action with ubuntu VMs. If your project's opensource, definitely use the macos-latest VM instead.

[stefan-niedermann]

My dear, i am such an idiot. I read about the slow Linux VMs, and i was so sure, i explicitly set macos-latest, but i just double-checked it and i really set a linux vm.

Sorry and thanks for the quick response. 🚀
