I've seen many posts with a similar problem and tried many solutions but so far none have helped. This all started after I upgraded Genymotion from 2.5.2 to 2.6.0.
I'm using Android Studio 1.5.1 on Ubuntu 15.10 64 bit. The Genymotion plugin is version 1.0.7. VirtualBox is 5.0.12 r104815
When I try to start a Genymotion Emulator I get:
I have several machines defined and all do this.
However, I can start them from the Genymotion app.
One other piece of information...if I have Android Studio and Genymotion running I get the following error when I try to issue any adb command from the command line:
adb server is out of date. killing... cannot bind 'tcp:5037' ADB server didn't ACK * failed to start daemon * error:
I've tried restarting the computer, restarting Android Studio, and removing and reloading the plugin. I've also set Genymotion to use the same adb that Android Studio uses.
Any ideas? Let me know if you need more info.
Thanks, Rich
