Android adb server version (32) doesn’t match this client (Genymotion)

Probably you have seen this type of error when using Genymotion as the Android emulator on which you test your device. This is how the error looks like:

adb server version (32) doesn’t match this client (35); killing…
error: could not install *smartsocket* listener: Address already in use
ADB server didn’t ACK
* failed to start daemon *

There is one simple thing that worked for me. I opened the Settings menu of Genymotion, then ADB tab and selected: Use custom android SDK tools and I set the path to the tools. By default Genymotion uses its built-in tools. After that killing all working emulators and starting them again makes everything  work.

Hope I have helped!
