The much anticipated Google I/O, an annual developer conference, kick started on Wednesday in San Francisco, with the giant search engine introducing several devices from new version of Android to Nexus to Project Glass.

Here is Google I/O keynote on day 1:

Android Activation

Starting the keynote, Google announced that more than 400 million Android devices have now been activated, up from 100 million last June. It also said that twelve new Android devices are activated every second - that's more than 1 million a day.

Android 4.1 Jelly Bean

Google rolled out a new version of Android called Jelly Bean, an improvement from Ice Cream Sandwich. Jelly Bean uses cards to help gets the right information at the right time.

"Starting in mid-July, we'll start rolling out over-the-air updates to Galaxy Nexus, Motorola Xoom and Nexus S, and we'll also release Jelly Bean to open source," said Andy Rubin, Senior Vice President of Mobile and Digital Content.

Google Play

Google Play is your digital entertainment destination, with more than 600,000 apps and games plus music, movies and books. It's entirely cloud-based, which means all of your content is always available across all of your devices. Google will also offer magazines, episodes of broadcast and cable TV shows, purchase and rent movies etc.

Nexus 7

All of this great Google Play content comes to life on Nexus 7, a powerful new tablet with a vibrant, 7" 1280x800 HD display. The Tegra-3 chipset, with a quad-core CPU and 12-core GPU, makes everything, including games, extremely fast. And best of all, it's only 340 grams, lighter than most tablets out there. It comes preloaded with some great entertainment, including the movie "Transformers: Dark of the Moon," the book "The Bourne Dominion," magazines like Condé Nast Traveler and Popular Science, and songs from bands like Coldplay and the Rolling Stones.

Nexus Q

Nexus Q combines the power of Android and Google Play to easily stream music and video in your home - all controlled by an Android phone or tablet. Designed and engineered by Google, it is a small sphere that plugs into the best speakers and TV in your house. It's the first-ever social streaming device like a cloud-connected jukebox where everyone brings their own music to the party.

Project Glass

Google also highlited the amazing potential of Project Glass at the conference.

"This morning at the Google I/O conference we did a special kind of demo. I'm very proud of the talented skydivers, mountain bikers and rappellers we worked with to push technology limits while showing the amazing potential of Project Glass," wrote Sergey Brin, Co-Founder.

Project Glass Demo: Hangouts In Air

The three-day conference, Google I/O, will feature more than 130 technical sessions, 20 code labs and 155 Sandbox partners. Over 40 sessions on Android, Chrome, Google+ and your favorite APIs will be streamed live.
