Android is an operating system based on Linux produced by Google that targets smart, portable and/or embedded devices such as phones, tablets, smartwatches, televisions, cars and other embedded systems. Android was originally developed by a company called Android Inc. Google later acquired the company in July 2005 and then made the Android SDK available in November 2007. One year later, the first version of Android was released in September 2008.
From Android 1.5 until Android 10, every major Android version had a name based on different desserts in alphabetical order. Since Android 10 to 12L, the version number is used instead in official releases, while the dessert names only remain for internal codenames. Starting from Android 13, the dessert name is mentioned in the public SDK and shown in developer previews and early beta versions.
Starting from Android 14 QPR2, Android uses a trunk stable development model. Every quarter the platform will advance to a much more recent version of the primary development branch, with incomplete/unreleased functionality being disabled through configuration (aconfig) build system flags.
In January 2020, Microsoft released the first preview of their custom Android experience meant to run on the Surface Duo, build 2020.117.2.
Timeline
The codenames are named after desserts, similar to how Ubuntu's codenames were named after animals.
