Supported

Android "Oreo" (codenamed Android O during development) is the eighth major version of the Android mobile operating system. It was first released as an alpha quality developer preview in March 2017 and released to the public on August 21, 2017.

Google unveiled a statue of the dessert-themed update at 14th Street Park in Manhattan, close to the original Nabisco factory that created the first Oreo.[3]

The Sony Xperia XZ1 is the first device available with Oreo pre-installed.[4][5]

History

Android Oreo was internally codenamed "Oatmeal Cookie."[6] On March 21, 2017, Google released the first developer preview of Android "O",[7][8][9] available for the Nexus 5X, Nexus 6P, Nexus Player, Pixel C, and both Pixel smartphones.[10]

The second, considered beta quality, was released May 17, 2017.[11]

The third developer preview was released on June 8, 2017 and offered a finalized version of the API.[12] DP3 finalized the release's API to API level 26,[12] changed the camera UI, reverted the Wi-Fi and cellular connectivity levels in the status bar back to Wi-Fi 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.[13]

On July 24, 2017, a fourth developer preview was released which included the final system behaviors and the latest bug fixes and optimizations.[14]

On August 18, 2017, Google launched an eclipse-themed teaser website, stating the release date and name unveiling of Android O as August 21, coinciding with the solar eclipse in the US.[15] The name ultimately turned out to be "Oreo", as a partnership between Google and Nabisco, the producers of the world-famous cookie.[16] Factory images were made available for compatible Nexus and Pixel devices later that day.[17]

Features

User experience

Notifications can be snoozed, and batched into topic-based groups known as "channels".[18][19] Android Oreo contains integrated support for picture-in-picture modes (supported in the YouTube app for YouTube Red subscribers).[20][21][22][23] Adding a custom ringtone, alarm or notification sound is simplified.[24][25] The "Settings" app features a new design, with a white theme and deeper categorization of different settings.[26] Android TV features a new launcher.[27] Google claims faster startup times from a powered-off state,[28] and improved battery life by minimizing background activity for infrequently used apps.[29][30]

Platform

Android Oreo adds support for Neighborhood Aware Networking (NAN) for Wi-Fi based on Wi-Fi Aware,[31] wide color gamuts in apps,[32] an API for autofillers, multiprocess and Google Safe Browsing support for WebViews, an API to allow system-level integration for VoIP apps, and launching activities on remote displays.[7] Android Runtime (ART) features performance improvements[7] and better cache handling.[33] Android Oreo contains additional limits on apps' background activities in order to improve battery life.[34] Apps can specify "adaptive icons" for differently-shaped containers specified by themes, such as circles, squares, and squircles.[35]

Android Oreo supports new emoji that were included in the Unicode 10 standard. A new emoji font was also introduced, which notably redesigns its face figures to use a traditional circular shape, as opposed to the "blob" design that was introduced on Android "KitKat".[36][37]

The underlying architecture of Android was revised so that low-level, vendor-specific code for supporting a device's hardware is separated from the Android OS framework using a hardware abstraction layer known as the "vendor interface". Vendor interfaces must be made forward compatible with future versions of Android; theoretically, OEMs would only need to perform their necessary modifications to the OS framework and bundled apps to update a device to a future version of Android, while maintaining the same vendor interface.[38] The "seamless updates" concept introduced in Android 7.0 is updated to download update files directly to the system partition, rather than requiring them to be downloaded to the user partition first, thus reducing storage space requirements for system updates.[39]

Android Oreo introduces a new automatic repair system known as "Rescue Party"; if the operating system detects that core system components are persistently crashing during startup, it will automatically perform a series of escalating repair steps. If all automatic repair steps are exhausted, the device will reboot into recovery mode and offer to perform a factory reset.[40][41]

A tailored distribution for low-end devices known as Android Go is also being made available, which will be used on all devices with 1 GB of RAM or less. These devices will ship with platform optimizations designed to reduce mobile data usage (including enabling Data Saver mode by default), and a special suite of Google Mobile Services designed to be less resource- and bandwidth-intensive. Google Play Store will also highlight lightweight apps suited for these devices.[42][43]

Security

Android Oreo re-brands automatic scanning of Google Play Store and sideloaded apps as "Google Play Protect", and gives the feature, as well as Find My Device (formerly Android Device Manager) higher prominence in the Security menu of the Settings app. As opposed to a single, system-wide setting for enabling the installation of apps from sources outside of the Google Play Store, this function is now implemented as a permission that can be granted to individual apps (i.e. clients for third-party app repositories such as Amazon Appstore and F-Droid). Verified boot now includes a "Rollback Protection" feature, which enforces a restriction on rolling back the device to a previous version of Android, aimed at avoiding a potential thief from bypassing security measures by installing a previous version of the operating system that doesn't have them in place.[44][45]

Issues

There are multiple Bluetooth connectivity issues that were not present in previous releases.[46]

Android Oreo may use mobile data even if Wi-Fi is enabled.[47]
