Chrome App inside an Extension

Question

I am trying to create a Chrome app but I need it to be accessible from any web page the user is viewing as the app is supposed to interact with the content of the page. From what I have seen, this is only done through extensions, but apps are the only ones that have the file system permissions needed to do what I am trying to accomplish.

Is it possible wrap a Chrome app with a Chrome extension to get the best of both worlds?

Answer 1

It should be possible to write both an app and an extension that interact through External Messaging.

Your question is a bit unclear as to what you want to achieve (a single item? then, no), but it's the best approximation.

Answer 2

It's hard to prove a negative, but I'm about 99.99% sure the answer is no.
