Chrome packaged application and Facebook redirect url

Question

I have a Chrome Packaged Application that I am currently integrating with the Facebook API. The Facebook Javascript SDK requires that I provide the URL of where my application is hosted and for security reasons they only redirect to this url.

The problem is that a Chrome Packaged Application doesn't have a url. I am aware of the chrome.extension.getURL but this url is not static, it changes per installation. Is there any way to set a URL for a Chrome Application that works for all installations?

Answer 1

Once you publish your app the id from chrome.extension.getURL will not change. The id matches the key used to sign the extension and once you publish an extension to the Web Store that key doesn't change. Developing locally will be more annoying since each time you "load an unpacked extension" it will get a new id.
