I am having trouble with this. here is a try push that the run job is blue and keeps retrying, basically the emulator is not able to startup.

I see stuff in the emulator logs:

overall it looks like things are working (no glaring errors), but obviously something is wrong. Maybe other logs could help out.

Ted, would you have some ideas as to why this is happening and what we could do to get this to work?

A few thoughts..

• We seem to be using emulator 32.1.15.0 which is about two years out of date. https://developer.android.com/studio/releases/emulator#32-1-15
• We can try to update the emulator, but that looks tangled up in dropping Android 7. https://searchfox.org/mozilla-central/rev/59cf9b740d7f5db77c595d0c886734780bfb257b/taskcluster/scripts/misc/repack-android-emulator-linux.sh#13-14 . It isn't clear that that is what is blocking us though, but we could have multiple emulators staged if we need.
• The live.log shows that mozharness times out before successfully booting. We could try bumping the timeout if the modern images are just slow to boot. https://searchfox.org/mozilla-central/source/testing/mozharness/mozharness/mozilla/testing/android.py#221
• The ERROR | Running multiple emulators with the same AVD message seems to be tied to us restarting the emulator a few times without cleanly shutting down the previous time. This is kind of gross, but we probably want to just ignore this if we can get the emulator to actually boot the first time.

Start with bumping the 330s timeout to something much larger and see if the screenshots show better progress through boot.
