Google focuses on Android, development of Internet of Things, Photos, and virtual reality at this year's Google I/O developer conference. The conference began with a brief introduction to Android M, Google's next software for mobile devices. From there, they went on to celebrate their first billion user products and the release of Android Pay. Needless to say, this wasn't a super Chrome-focused sort of day. This was a day of mobile engagement from the start of this first keynote to the end. All about movement and tiny device software.
