App Runtime for Chrome (ARC) Welder allows Android apps to run on Chrome for Linux, Windows, and OS X systems. Google launched a limited beta “ARC” project last year at Google I/O developer event, which now expanded to run millions of Android apps within Chrome browser. Google’s ARC Welder app can now run any of your favorite Android apps like WhatsApp, Candy Crush, Angry Birds, all from your Chrome web browser. The tool operates via some special runtime implemented using Native Client (NaCl) in-browser binary execution tech.
