Much awaited annual conference by Google took start yesterday, with the event tickets sold out in less than an hour.
Google I/O day 1 brought handful of exciting announcements.
First of all, the big surprise of Google's I/O keynote was a Samsung Galaxy S4 running stock Android! Although the details are still somewhat scant, Android VP Hugo Barra said simply that "it's pretty awesome", with the great battery life and super-fast responsiveness. Hugo Barra commented that it’s not a finished product yet, having really only come together in the last week. This Nexus device combines Samsung's great camera and display with the purest form of Android (and LTE support). The phone is expected to become available for $649 by June 26th.
Android / Chrome boss Sundar Pichai also made an impressive announcement on stage at Google I/O 2013, revealing the key stats of Google’s mobile OS. 900 million Android devices have been activated since Google's mobile operating system launched to consumers four and a half years ago, with over 48 billion apps been installed thus far! It’s been forecasted that Android could cross the billion activation mark by the end of this year!
With Android 4.3 still being a mystery, it has been confirmed in a search listing on Google's developer website and is expected to support Bluetooth Low Energy (BLE) and the OpenGL for Embedded Systems 3.0 graphics specification. This will help conserve battery life on mobile devices that connect to peripherals like smartwatches and speakers, and OpenGL allows for advanced visual effects in games and graphics-intensive applications.

Google also announced its brand new development environment for Android
at Google I/O: Android Studio. Hugo Barra, VP of Android product management, commented: “This is just scratching the surface of all the new features in Android Studio." Moreover, the developer console has also been improved, with more ability given to the developers to earn money from the Android Apps.
Hangouts: a unified messaging system for Android, iOS, and Chrome was also unveiled, replacing Google Talk, Google+ Messenger, and the original Google+ Hangout video chat service — Hangouts will eventually replace all of Google's communication properties. It’s basically a messaging app, in the same realm as WhatsApp and Facebook Messenger, but with some of its own twists, including Google Voice integration and more.
Stay tuned, we’ll be back with more news from Google I/O 2013 soon! By then, do not hesitate to share your thoughts in the comments below!
