Google provides 1st peek at next Android operating system

Google is previewing the next version of its Android operating system two months ahead of schedule in an effort to get the upgraded software on more mobile devices.
The new rendition initially is being recommended only for mobile app makers and will only work on a few smartphones and tablets.
Google usually hasn't released test versions of Android until its annual developers' conference. The event begins May 18 this year.
The upgraded software, known as "Android N" for now, offers a split-screen feature so users can toggle between apps and the ability to reply directly to notifications. Those options are already on the operating system that runs Apple's iPhone.

Although Android powers most of the world's smartphones, it often takes years before consumers install upgraded versions of the software.
