Hey everyone, so I looked into this deeper and I think the new behavior stems from the new Android emulator package that was released on March 29th. See https://developer.android.com/studio/releases/emulator.html#28-0-25.
I did some tests on Travis CI and it seems that the only armeabi-v7a based emulator that’s working now is the android-24 one i.e. "system-images;android-24;default;armeabi-v7a".
I have a sample config that you can look into here: https://travis-ci.org/cotsog/travis_ci_prod_regular/jobs/516178009/config.
Could you try this out and let us know if it helps?
Thanks!
