Android O is officially “API Level 26.” The Play Store and SDK are ready for apps.

Less than a month after the release of the second Android O developer preview, Google is back dropping yet another version of the OS on us. The third developer preview should be rolling out to beta devices now, and along with an update to the Android Studio SDK, it finalizes the APIs for Android O.

Android O brings a revamp of the notification panel with snoozable notifications and a whole new settings app. There's easier updating with Project Treble, totally redesigned emoji, and a low-end phone configuration called "Android Go." Phones get picture-in-picture mode, Android TV gets a new home screen, and faster boot times should help every version, but cars with Android should especially benefit from it.

The Android O APIs are now officially finalized as "API level 26." With the finalized APIs, Google says developers should be testing apps to ensure they still work after the changes to background limits, networking, and security. The Play Store is also ready to take API Level 26 apps and start sending them out to users.

The O Developer Preview is available for the Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, and Nexus Player. Users signed up to the Android Beta Program should be receiving an update any day now. There are also updated system images for manual flashing. We're still due for one more preview in July, and Google says the consumer release will be "later in the summer."
