x/build: Android emulator builders sometimes fail with: go_android_exec: no exit code: ""

[eliasnaur]

For example:

https://build.golang.org/log/f8a11e4d226addf61b7bb461663e63e34b699783 (android/amd64)
https://build.golang.org/log/a30de87209a4b63ed9fc511199bfcbe2aade16e9 (android/386)

I seems to be a bug in adb. I reported it here:

https://issuetracker.google.com/issues/73230216

Change https://golang.org/cl/93395 mentions this issue: misc/android: retry if adb fails to output anything

It seems like the upstream issue hasn't seen any activity, unfortunately. I count 6 occurrences just in the first page of build.golang.org, which makes it the most common flake on the Android builders by far.

Yes, and the issue also blocks my hope of having android emulator builders in the trybot set. If it's not too inappropriate to ask, could someone at Google prod the Android team for progress on the upstream issue?
