I've had a very awful experience using the emulator quick boot.
its suppose to allow the emulator to open under 6 seconds with state preserved. it is just constantly freezing or shows an error of "guest is not online". I'd rather just disable quickboot but i cant find an option for it. Is there any adb command then that can be used to disable quick boot ?
I"ve tried with emulators running api 23, & 26 on mac high sierra with Hax 6.2.1
as pointed out in the comments there is now a quick boot option in the AVD Manager when editing/creating a emulator. I set mine to cold boot to disable Quick boot.
