Android O: First Developer Preview released by “Android 8.0”

Android O: First Developer Preview released by "Android 8.0"

Without a media-aware idea, yes without any advance notice, Google has released the first preview of the next Android for developers. Android 8.0 is called Android O and can be installed on the Nexus 5X, 6P, Player as well as Pixel, XL and C devices.

As major innovations in the next version of Android, Google first presents the aspects “Notification Channels”, “Picture-in-Picture”, “Autofill” and “Adaptive Icons”.

Notifications in categories

With the new Notification Channels, users should be able to assign apps notifications to different categories, which can be individually customized in their properties such as urgency, sound, color, vibration, visibility on the screen, and the behavior when “not disturbing”. By touching it long, an app can be assigned to an app immediately upon its appearance, and the developer of the app no ​​longer has any influence on its behavior; Provided it uses the new API, because untapped apps still behave as they are used by Android 7.0. The new API is not yet mandatory.

Picture-in-picture as with Android TV

With Android O, apps on smartphones and tablets will be able to play back an image in the picture. As a rule, it should be the presentation of videos. So far, this feature was only available on Android TV.

More easily

With the Autofill framework, Android O is designed to simplify the handling of forms, such as the input of address or credit card information, because the data required for this can be stored centrally and accessed decentrally in apps. This is intended to reduce user effort and eliminate a source of error.

Customizable app icons with two layers

With the Adaptive Icons, Google provides developers with new guidelines for deploying logos for apps. They will consist of two levels – the background and the logo. The logo itself is 72 × 72 pixels much smaller than the 108 × 108 pixel area, which ensures that icons can be displayed automatically in various forms without blending. Two layers also allow for effects such as parallax.

Advanced Farbraume, Multi-Monitor and Wi-Fi Aware

Further innovations in Android O concern, among other things, the identification of displays with extended color schemes such as DCI-P3. Apps, which make use of it, can then use the respective optimal representation on appropriate terminals. In addition, Android O provides an API for handling multiple displays, where apps can be pushed back and forth – but only one can be active.

With Wi-Fi Aware, Android O also supports a Wi-Fi Direct extension on compatible devices that allows end-users to continually look for other end-to-end devices that can connect without a wireless router.

Stronger specifications for apps in the background

With background limits, Google introduces three new categories for dealing with inactive apps. With the classes implicit broadcast, background services and location updates, developers should be able to more easily determine what an app is doing in the non-active state, which in turn increases the battery-time of the terminal.

Test at your own risk

The decision to release Android O before the Google I / O in May, justifies Google with the great benefit from the feedback from the testers, but directs a warning to the community: ” We are very early, more features will come, and We still have a lot of work to do in terms of stability and performance. But it booted! 🙂

More details about Android O Google will reveal Google I/O 2017, which takes place from 17 to 19 May.
