Reference: Genymotion how to debug with Chrome Dev Tools
I'm also trying to get chrome developer tools to work with a genymotion emulator. However, when I follow all of the steps recommended (including at the above link), I don't get the "inspect" link. See: http://neu14.com/demos/screenshot.png
Note: I found out that the default browser on the android devices, at least on most of the prior os versions is not Chrome. Finding an apk to download for Chrome android compatible versions, without an actual google play account, is quite challenging?
