A question about the <intent> tag

Hi,

I am working on developing an UA on Android now, I mean, out of the Chrome
world. The problem is it seems now most working demos are implemented as a
Chrome extension which is registered by its manifest file.

I tried the apps on http://demos.webintents.org/, but unfortunately the
ones I need now seem to have bugs out of Chrome.

My question is how I can find the registration data (which should appears
in the <intent> tag) of the web intents extensions in the Chrome Web Store?

Thanks
Cheng
