The Android team relies on the Jenkins Android emulator plugin for CI emulator testing, but it is increasingly a stretch to call it actively maintained. The GitHub repo has 13 open pull requests and its last commit was May 23, 2016. Its constants file has not been updated since Android 6.0 (for context, 7.1 is the current version and 8.0 will likely ship in the next few months). Due to some no-longer-valid hardcoded bits in SdkInstaller.java it is now blocking T150623.
If we are going to continue relying on this piece of software I propose that we fork it so that we can update it as needed to provide us the functionality we need on an ongoing basis.
