Alas, I have not got this working yet. When I point Cocoon at my zip file in Dropbox it displays an error:
Could not launch your app. Please verify your internet connection.
Now, this sounds like an obvious error but the WiFi on my phone is working. I know this because I sent, received and copied the Dropbox URL from my Gmail account on my phone. I also know there are no typos.
Am I missing something simple here?
PS - I have a Samsung Galaxy S
EDIT: I also tested the URL in chrome to ensure that the link was correct. This was OK.
EDIT #2: Ok. I realised my mistake in the end. I initially put the zip file into a private folder and copied the link. Even though I could download the file from my browser it didn't work with Cocoon. I put the zip file into the public folder and then copied that link. It worked a treat. It may have something to do with the private folder link started with https:// but I'm not sure about that.
