Could you give some more context here about why this is needed? Is it
because Google is moving Chromebooks to Android?

We also need to think about if this needs addition of an Android build to
CI and who will support that.

Also, it seems Android was added previously but removed in 2017 in
430946d0b881 ("igt: Remove Android support"). So this seems to be a new
attempt to add Android to IGT.

Thanks.
