Android M will now officially be known as Android 6.0 Marshmallow.
Google revealed the next version with the unveiling of a new Android statue in front of the iconic Building 43 at their Mountain View campus. Some people were speculating that Android M might have been called Android 6.0 Milkshake, as indicated by the watch face that was on the watch that Google’s VP of Engineering, David Burke was wearing back at Google I/O 2015.
