Google on Tuesday launched the fourth and final developer preview of its latest Android OS, Android O, indicating that the official release of the new mobile OS is inching closer. There aren’t any major changes in this release except for incremental upgrades and ‘stability’. The fourth developer preview includes the final system behaviours, the latest bug fixes, optimization and final APIs for Android O that arrived with the third developer preview.
With this new release, the Android Support Library (version 26.0.0) is now said to be stable. Ars Technica points out that Android Support Library is basically a collection of libraries which developers can add to their apps to bring some of the latest Android features to an app, irrespective of the ‘host OS’ version.
Moving on, all the major Android SDKs, tools and the Android Emulator will get incremental upgrades in the next few days, Google said in its blog post.
Notably, the latest version of Android will mostly bring better notifications support ‘across the OS’, autofill, picture in picture support, notification channels and dots, shortcut pinning etc., for developers and users as well. It is also said to include features that will help users to optimise their phone battery.
“Battery is also a top concern for users, so they’ll appreciate your app being optimized for background execution limits and other important changes in vital system behavior for O apps,” Google wrote in its Developer blog post.
As with past previews, the only supported devices for this new release include select Pixel and Nexus smartphones. Factory images for Android O fourth developer preview can be flashed on the following compatible devices- Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, Nexus Player. Users can alternately opt-in their eligible device by visiting the android.com/beta page. The final version of the new Android OS Android 8.0 ‘O’ will be out “later this summer.”
