Reports indicate that like last year Google will follow the lottery system to pick the I/O attendees from the interested developers. So, just register for the event and hope that you get picked.
To remind you, I/O is Google’s flagship developer event of the year and it includes several developer related announcements as well as sessions from Android, Chrome, Google+, and other divisions of the search giant.
We expect to hear about the next Android version at this year’s I/O along with improvements on Android TV, Wear and Auto platforms. Google will also most likely talk about developments on Chrome OS as well as Google Glass, Project Tango and Project Ara.
You can find more information about I/O 2015 at the official website.
