What to expect at Google I/O 2015

Google talks a lot. Unlike Apple, which primarily speaks through its public-facing product events that take place a few times a year, Google tends to announce updates to its products, along with new ones, with reliable regularity.

Nonetheless, Google usually saves much of its best stuff for Google I/O, its annual developer conference, which begins Thursday morning. Last year, it used the event to unveil Android TV, Android Auto and Android Lollipop (then just called "L"). It was also the launchpad for Android Wear.
