If you've bemoaned the inability to use your personal Android phone for company business, Google has some heartening news. It just unveiled Android for Work, a code platform that lets your business and personal info coexist on a single device. The technology (derived from Samsung's Knox) keeps the data types separate without requiring any changes to existing apps. Every major Android manufacturer should have Android for Work certification in the fall, with promises of both guaranteed updates and full security. The office-friendly feature is baked into the Android L release from the start, but don't despair if you're toting an older device -- Google is promising an app that works on Android gadgets running Ice Cream Sandwich or later.
