The stream is over but you can check the key highlights here:

Google's I/O 2015 developer conference is set to kick off in a few minutes and we've got you covered with live video of all the major announcements going down at San Francisco's Moscone Center. The keynote is scheduled to start at 9.30 AM PDT / 11.30 AM CDT but the stream will open a little earlier.

What's on the agenda? The next version of Android will likely take center stage, with rumors pointing at new features like universal fingerprint support, granular control of notifications and app permissions, and a brand new standalone Photos app. There's also some speculation that the update is going to be very work-focused, as evidenced by an event listing that says "Android M is bringing the power of Android to all kinds of workplaces." 

As for what Android M stands for, the internal name is reportedly "Macadamia Nut Cookie", but Google will likely wait until the operating system's formal release this fall before revealing its name, as it did with Lollipop. Don't let us stop you from venturing a guess, though. Marshmallow? Muffin? Milkshake?

Other than that we'll be on the lookout for updates to Android Wear, Google Cardboard, Chrome OS, Android Pay, Android Auto, Brillo, Project Fi and more – Google's keynotes are usually two-and-a-half hours long.
