Catch up on what you might have missed.

Day one of Google's annual developer conference has passed, and as promised there's a ton of video from all of the sessions to check out. Google is only livestreaming select sessions this year, but they will all be recorded and published on the Google Developers and Android Developers YouTube channels. We've taken the liberty of cherry picking some of the great sessions you might have missed yesterday, so you can catch up on all of the great things happening in Mountain View right now.

What's new in Android N

Every year we get a What's New in Android session, and this year is all about N. This year is a little unusual, since we've had access to the developer preview for Android N for a little while already, but with the release of what Google is calling "beta stable" Android N Preview images there's a little more to look at. We've got a great list of the changes coming to Android N if you're unfamiliar with what has been happning with this soon to be crowdsourced flavor of Android, but if you've got 45 minutes to kill this session is a fantastic breakdown of some of the important changes on the way.

Android Auto: The Road Ahead

Some big changes are coming to Android Auto over the next few months. We've already seen plans to make a standalone app for use in the car without an embedded screen to connect to, but there's a lot more going on with the interface itself. This session does a great job breaking down all of the changes coming to Android Auto, including how it's going to be more accessible to everyone in the not-so-distant future.

Android Pay everywhere: New Developments

Google continues to push forward with new features for Android Pay, and this session is all about breaking down all of the new things headed to the world of seamless transactions through your smartphone. Android Pay headed to ATMs, Android Pay ready to roll on the updated N Developer Preview, and the expansion of what it means to make a payment with your phone are all bit topics for this presentation.

Shinier, faster mobile games with Vulkan

Now that Google has started moving to make Vulkan a big part of the Android experience with the N release, developers need to be shown how valuable Vulkan can be for gaming on Android. As we've seen from talking to existing developers, Vulkan's biggest challenge is adoption. With Google leading the charge and walking developer through the benefits of Vulkan, there's a good chance we'll see some great Vulkan apps by the time a new Nexus is rolling out.

Introducing Project Tango Area Learning

Project Tango is a fascinating idea Google has been working on for a couple of years now, and as the platform becomes more capable there are an increasing number of reasons to be excited about what it means for the future. Google's first Tango session of I/O this year is all about Area Learning, which allows Tango to see and "remember" the physical space around you. In this video, Google shows off a little of how Area Learning works and how it will be helpful for the future of Augmented Reality.

Behind the scenes: What's new in Android accessibility

Accessibility features don't usually get time to shine in a keynote presentation, but they are frequently some of the most important parts of a smartphone to users with disabilities. This sessions breaks down how some of the significant accessibility features that have been added to Android N work, and how those feature are useful to everyone.

Keynote in 360

You've probably already seen the keynote from this year, but have you checked it out in a 360-degree view? Google made the video accessible live for folks who wanted to tune in through Google Cardboard and feel like they were standing in the crowd to enjoy the presentation. It's a fun demonstration of how Google is managing 360-degree video, as well as a way to see the resolution Google is working with for their live streaming 360-degree videos.
