Communicating between a Chrome packaged app and a Chrome extension?

阅读更多关于 Communicating between a Chrome packaged app and a Chrome extension?

It seems that neither a packaged app nor an extension can achieve both these things, so I'm now considering trying to achieve what I'm after with a separate packaged app and extension communicating.
