As we get closer to Google's big event – Google I/O 2013 – the company has released an update to the Android app for the event. The update brings a number of new features to the app that more or less turns the app into one of the most useful things an attendee can take along with them for Google I/O 2013.

Some of the new features of the app include the ability to scan attendee badges using NFC, schedule changes synchronising between devices, a lock screen widget for checking schedules quicker for Android 4.2 devices, vector-based maps with session information, dedicated HDMI video output for livestreams, automatic Wi-Fi setup for attendees and an off-site attendee mode for livestream-only viewers.

While the new update does bring the ability to livestream events, it's still not very useful if you don't actually plan on going to the event itself since most of the new features are location-based. The app is available for free on Google Play and will be open sourced a few weeks after the event.

Google is expected to show off a number of new things at the event, including a much-awaited new version of Android. Originally, Google was expected to showcase the next major version of Android, numbered at 5.0 and codenamed Key Lime Pie, but that seems to not be the case as evidence has popped up that the next version will instead be numbered at 4.3 and will stick to the Jelly Bean codename. Other than a new version of Android, Google is also set to show off a new refreshed version of the Nexus 7 tablet.
