According to the website, it has a countdown timer to the eclipse which is taking place on the 21st of August. Google writes, “On August 21st, a solar eclipse will sweep across the entire United States for the first time since 1918. Android is helping you experience this historic natural phenomenon so you can learn more about the eclipse and count down to the big day—when you’ll meet the next release of Android and all of its super (sweet) new powers, revealed via livestream from New York City at 2:40PM ET.”
This is in line with what we had previously heard in which it was suggested that Android O could be officially launched on the day of the eclipse along with its name, which at the moment seems to be more than likely known as Android Oreo. This would be an interesting move as it means that Google could be doing another collaboration with a brand, like they did with Android 4.4 KitKat. In any case we should find out pretty soon so check back with us in the next couple of days for the details.
