I am getting below error:
emulator: ERROR: Unfortunately, there\'s an incompatibility between HAXM hypervisor and VirtualBox 4.3.30+ which doesn\'t
You likely have two emulators that are trying to use the same resources on the computer i.e. both the Google one and the Genymotion (VirtualBox) one. Who knows how long/if that will be addressed. If you are running Genymotion you use VirtualBox. So, try to run the Oracle VM Virtual Box Manager and check that no virtual machines are running and shut down any that are. You should be able to run emulators in studio again, just make sure you pick one (Genymotion) or the other (Android AVD manager).
