with os dialog you can shot a photo from a qr code
and the url will be displayed (if possible).
by button you can open link in your default web browser.
you need a cam with (auto) focus.
i made this app for myself,its nothing special.
notes to permissions :
the permissions are default by application game kit development tool.
1. system-tools standby-mode
the device should not sleep if you do a few seconds nothing in app.
2. netcommunication internet access
not used by this app, with the app game kit you can make also a multi player game,
facebook actions or in game advertising.
3. memory sd-card contens change/delete
the app should only have access to the path given by os
and save only settings or his state.
maybe it exists if you install at sd-card.
