Android M is no longer being code-named but has an official name. The next mobile operating system from Google will be called Android Marshmallow, CNet reports.

Android Marshmallow has been referred to as Android M since May when it was announced at Google's annual developer conference, Google I/O.

Google has a history of giving its Android operating system updates a new sweet name each time. Before Marshmallow, there was KitKat and Lollipop.

Android is a big focus for Google. Android is used in more than 80 percent of mobile device in the world today, with companies like HTC, LG, Samsung and Motorola using it in their devices. Google wants people to use its other services like Google Maps, YouTube and Google search while they are using their devices to keep them loyal to the Google brand.

The official release for Android Marshmallow is expected sometime this fall, likely September. Developers are already testing the beta versions of Marshmallow, and they will continue provide feedback to Google as they test it out, according to Tech Radar.

AndroidPay will work with Android Marshmallow. The service will allow for mobile payments at a variety of retailers. Users will not be required to open up any app to use the service, instead transactions will be performed by simply placing the device on the compatible payment terminal.

Fingerprint sensors will also be a big part of Android Marshmallow. Users will be able to unlock their phones and authorize transactions, but they will also be able to use fingerprints for other apps and for password entry.

The Google voice recognition features will see an improvement as well. Users will be able to tell Google to do something and Google will talk back. For instance, users can tell Google to open a music program and the program will ask them what they would like to listen to. It will be a much more natural conversation between the user and the device.

Android Marshmallow will likely debut first on Google Nexus phones and tablets.
