ADB server version (36) doesn't match this client (39); killing [duplicate]

Solution 1:

This works for me...

• go to GenyMotion settings -> ADB tab
• instead of Use Genymotion Android tools, choose custom Android SDK Tools and then browse your installed SDK.

Solution 2:

In my case this error occured when I set up my environment adb path as ~/.android-sdk/platform-tools (which happens when e.g. android-platform-tools is installed via homebrew), which version was 36, but Android Studio project has Android SDK next path ~/Library/Android/sdk which adb version was 39.

I have changed my PATH to platform-tools to ~/Library/Android/sdk/platform-tools and error was solved
