Google Launches Android O: Developer Preview Image is Now Available

Google launches Android O with some interesting changes such as picture-in-picture mode, new notification channels, adaptive icons, and much more. Probably to be named Android Oreo, the first developer preview is now out.

The tech giant is continuing its transparency of pre-releasing early builds of new Android versions with the announcement of Android O Developer Preview. In the past, Google had released the Android 7.1 Developer Preview, which lets you get early Android builds via over-their-air on Nexus devices.

Android O Developer Preview includes an updated SDK with system images for all the supporting devices, including Nexus 5X and Nexus Player. Google launches Android O with a ton of new eye-popping features and APIs, so we’ll briefly highlight several of these below:

1. Background Limits

Android O puts a big focus on enhancing the battery life and a device’s interactive performance. The new version puts additional automatic limits on what apps can do in the background. To do so, it comes with three categories: Implicit broadcasts, location updates, and background services. Background limits represent a major change in Android.

2. Notification Channels

Android O unveils notification channels to provide a unified system, helping users to manage notifications with app-defined categories. It will let developers create a notification channel for different sorts of notification that they need to send.

Users can even manage most of the notification settings using a consistent system UI. All notifications posted to a particular channel will act the same.

Google’s Android O also deprecates developers to set priority levels for individual notifications. As an alternative, one can now set an optional importance level while creating a notification channel. After you succeed in creating a notification channel, only the system can customize its importance level, giving power back to users.

In addition, it gives users the ability to snooze notifications to reappear at a later time. Notifications reappear with the same importance level they first appeared with.

On top of that, Google launches Android O with new visuals and grouping to notifications.

7. Adaptive Icons

Google launches Android O with adaptive icons which can now display a range of shapes across different models and devices. Users can set a launcher icon using a circular shape on one OEM device and use a ‘squircle’ on another.

Each OEM device will offer a mask which the system can use to render all icons with the same shape. The OS also animates interactions with icons and utilizes icons in the Settings app, sharing dialog, shortcuts, and overview screen.

8. Wide-Gamut Color for Apps

Android O comes with a wide-gamut color display for apps. In order to display wide gamut images, apps will need to turn on a flag in their manifest per activity and load bitmaps with an embedded wide color profile.
