🚑 Detox, CircleCI and Android are not compatible

[a-tokyo]

Although Detox is supposedly compatible with CircleCI, It is impossible to run Android on CircleCI due to a requirements deadlock.

• Detox only supports macOS. https://github.com/wix/Detox#environment
• CircleCI MacOS machines come with Java 11. Which is supported by android command line tools https://developer.android.com/studio/ (refer to Command line tools only section for downloads for CI)
• CircleCI MacOS machines don't support running android emulator with Java 11 and latest command line tools due to Incompatible hardware. (Note, a common thought would be to go with Intel HAXM package installation, but it's not supported due to the hardware as well). CircleCI build hosts are Intel-based Mac.

Android Emulator requires an Intel processor with VT-x and NX support.

A workaround would be to use another emulator like Genymotion, however, that's not a viable approach for everyone.

We support Linux and Windows as well. Maybe we are a bit slower and less concentrated on fixing OS-specific issues, but still we do support all the three major platforms. пн, 14 лист. 2022 р. о 13:14 Ahmed Tarek ***@***.***> пише:

I updated our README to eliminate the source of the confusion.

@a-tokyo thanks for bringing this to our attention.
Mind that it's not that Detox support only MacOS, as @noomorph explained -- it's Apple that only allow for running iOS simulators on Mac machines. Android can be launched in any of the mentioned environments.
I'm not familiar with the specs of CircleCI but strikes me odd that they do not support Android emulators. Perhaps running in headless mode or using a non-default gpu setting would help.
