adb shell getprop init.svc.bootanim
This will tell you whether or not the boot animation is running. It's what we use on our headless build server to check if the emulator is up. The sys.boot_completed from dac2009 is what lead me to find that flag. We use init.svc.bootanim instead because boot_completed has a tendency of triggering too early.
How to load headless emulator in memory?
While I was testing @neuron's answer, I realized that I had to check for a different property to achieve the most reliable verification dev.bootcomplete (please note the prefix: dev and not sys, as sys.boot_completed turns to 1 way before initialisation has finished)
I found dev.bootcomplete to be unreliable too, I still prefer init.svc.bootanim
Note: This does not work if
-no-boot-animflag is enabled.
