I have just downloaded "PhoneGap-start" source, which is like a hello world that one can use to develop with PhoneGap.
Then I installed Ripple for google chorome to debug my app.
But there is the problem, when I start this hello world app it just shows me "connecting to device" and that's it.
I am googling that problem for good 6 hours, but non of the suggestions helped so far...
Hey I'm having the same problem and I just figured it out..
Click on the ripple icon in the top right then manage
After that check the checkbox that reads allow access to files..
refresh and it should work
