Android Oreo
Android Oreo (codenamed Android O during development) is the eighth major release and the 15th version of the Android mobile operating system.
It was initially unveiled as an alpha quality developer preview in March 2017 and later made available to the public, on August 21, 2017.
It contains a number of major features, including notification channels, picture-in-picture support for video, performance improvements, and battery usage optimization, and support for autofillers, Bluetooth 5, system-level integration with VoIP apps, wide color gamuts, and Wi-Fi Aware. Android Oreo also introduces two major platform features: Android Go – a software distribution of the operating system for low-end devices – and support for implementing a hardware abstraction layer.
As of September 2025, Android Oreo (which has ceased receiving security updates as of October 2021) ran 1.8% of Android devices.
Android Oreo was internally codenamed "Oatmeal Cookie." On March 21, 2017, Google released the first developer preview of Android "O", available for the Nexus 5X, Nexus 6P, Nexus Player, Pixel C, and both Pixel smartphones. The second, considered beta quality, was released on May 17, 2017. The third developer preview was released on June 8, 2017, and offered a finalized version of the API. DP3 finalized the release's API to API level 26, changed the camera UI, reverted the Wi-Fi and cellular connectivity levels in the status bar back to Wi-Fi being on the left, added themed notifications, added a battery animation in Settings: Battery, a new icon and darker background for the Clock app, and a teardrop icon shape for apps.
On July 24, 2017, a fourth developer preview was released which included the final system behaviors and the latest bug fixes and optimizations. Android "O" was officially released on August 21, 2017, under the name "Oreo", after the Oreo brand of sandwich cookie. Its lawn statue was unveiled at a promotional event across from Chelsea Market in New York City—a building which formerly housed a Nabisco factory where Oreo cookies were first produced. Factory images were made available for compatible Pixel and Nexus devices later that day. The Sony Xperia XZ1 and Sony Xperia XZ1 Compact were the first devices available with Oreo pre-installed.
Android 8.1 was released in December 2017 for Pixel and Nexus devices, which features minor bug fixes and user interface changes.
Notifications can be snoozed, and batched into topic-based groups known as "channels". The 'Major Ongoing' feature orders the alerts by priority, pinning the most important application to the top slot. Android Oreo contains integrated support for picture-in-picture modes. The "Settings" app features a new design which has been reduced in size, with a white theme and deeper categorization of different settings, while its ringtone, alarm and notification sound settings now contain an option for adding custom sounds to the list. Tooltips can also be set for views.
