Google just blogged about a few lines of code that would allow third party apps to integrate with Google Now. Would be great to be able to do a okay Google voice search and have it search within the plex app for shows/movies.

As explained on Engadget:
Google wants even third-party Android apps to be able to do searches using "Ok, Google" voice commands, so it's now making it easier for developers to integrate the feature. Now, all devs have to do is add a few lines of code to their AndroidManifest.xml -- they can even copy and paste those lines straight from the company's post in the Android Developers Blog. After that, users can issue vocal commands to make a query (for instance: "Ok Google, search for hotels in Maldives on TripAdvisor") from within the app. They can even do that from any screen on their phones, so long as they activate hot-word detection. Cool, right?
