Google has announced that the name of the latest version of its Android mobile operating system will be Android KitKat.
The internet giant has teamed up with Nestle, with the title following other sweet-themed names such as Android Cupcake and Android Jelly Bean.
There had been speculation that the latest version would be named Android Key Lime Pie.
Marc Vanlerberghe, director of Android marketing, said: "We couldn't imagine a better name for our Android K release than the tasty chocolate that's been a favourite among the team since the early days of Android."
Patrice Bula, Nestle's head of marketing, said: "We're excited to announce this partnership with Android, the world's most popular mobile platform, which will help us to enable even more KitKat fans to enjoy their break.
"KitKat is one of the world's top 10 fast-moving consumer goods brands in social media in terms of fan numbers and engagement.
"We continue to build on its strong digital presence with interactive, creative branding campaigns."
The release of Android KitKat will be marked with a competition to win prizes including 1,000 Google Nexus 7 tablets through more than 50 million specially-branded KitKat bars.
Consumers can take part by buying special packs of KitKat four-finger and KitKat Chunky multipacks available in Sainsbury's, Morrisons, Asda and Tesco.
