title: Android -- How does Google+ instant upload work?
body: <p>I was playing around with the new Google+ application on the Android and I had a technical question that I couldn't seem to find online. How does the instant upload hook into the native camera application?</p>
  
  <p>I can turn on a feature in the Google+ application and any pictures that I take with the native camera app are automatically uploaded to a private album on Google+. And this seems to be true whether the Google+ application is currently running or not. Is there any type of hook that I can register a callback event for in my application to access "just-taken" pictures for some post-processing goodness? I'd really like to tap into this functionality for an application that I am currently writing.</p>
  
  <p>Any insight or hints in the right direction are greatly appreciated! Thanks!</p>
