As I mentioned in my tutorial how to customize the exported HTML5 index.html
you can edit directly the file export-fs.html from the "C2 install base/exporters/html5" folder.
You will have to do this edit on every upgrade of C2 though, since those files will be overwritten/destroyed (as it is strongly advised to uninstall the previous version of C2 when updating to a newer one).
On the other hand, you're talking about accessing the game from android directly through the browser aren't you ? because I believe wrappers like cocoon.js deal with those kind of details "naturally".Kyatric2012-08-20 22:36:16
