Google today announced the first preview of Android O, the unnamed next version of its core mobile operating system. This early version of Android O brings with it a handful of new features that clearly target developers and device makers more so than end users. The primary consumer-facing function is a picture-in-picture viewer for Android phones (this feature is already available to Android tablets). Developers will be able to take advantage of a new background limiter, which can control how much power apps are allowed to consume when running in the background. Android O takes a new stab a notifications with what it calls notification channels. These will let users manage which types of notifications are allowed from individual apps, including new visual groupings that make it easier to see what's going on. The new Autofill API will let developers of apps such as password managers choose autofill defaults across keyboards. Adaptive icons for the home screen will automatically change based on system preferences so they can adapt to different phones and user interfaces. Android O adds new support for Bluetooth audio codecs, such as Sony's LDAC codec. Other features include: in-app pinning of shortcuts and widgets; support for Wi-Fi Aware; XML fonts; wide-gamut color apps; new WebView APIs; expanded accessibility options; improved support for multiple displays; and changes to the MediaPlayer, including new support for the MPEG2_TS codec for media streaming. Developers can install this first Android O preview on their Pixel, Pixel XL, Nexus 6P, Nexus 5X, Pixel C, and Nexus Player, but will have to do so manually via their computer. Google says Android O will see at least one more developer preview before the company releases a consumer beta of the operating system. Google didn't suggest when the final version of Android O might be ready, but it typically releases new Android operating systems in the fall.
