I’m working right now to integrate my app with facebook. I followed Jonathan and crawlspace tutos about SSO e like button.
By now, my app can post a comment and retrive users’ likes without problem. With that done, I would like to have my user like our page and our game. So, I build the like box and put it on our website. When the user touch a button within our game, I call the facebook.login and after that, I open a popup(or a newwebview, both of them has the same result) with our like box.
When the user touch the like button, the page asks him to login again and after a login, it shows an empty facebook (with visual headers) page.
Is there a way to avoid this behavior? If I ask for two autentications, is easier to receive a “hate” than a “like”.
