Android 8. Improved app notifications: Through notification channels, apps will have more control over the types of notifications they send, and users will be able to better manage notification settings. App icons can display a notification dot, alerting you that a notification needs to be addressed or dismissed. Picture-in-picture comes to phones: On phones and tablets, apps will be able to open a floating window for video playback.
Focus on power conservation and performance: Behind the scenes, Android 8. Support for autofill: Android 8. And more: The update will do a better job of managing fonts, reproducing colors, and handling audio.
And Oreo will support Wi-Fi Aware, also called Neighborhood Awareness Networking, which lets Android phones within range of each other receive notifications of applications or services in the area. Finally, Oreo will let users add shortcuts and widgets to perform actions and tasks. And wait. So far, handset makers and carriers have successfully resisted Google's push to get them to release major Android updates more quickly. OEM overlays and apps: It's great for the Android handset makers and carriers that Google lets them add their own custom interfaces and apps because it lets them differentiate their devices.
For the handset owners, however, it's not so great. Users have to navigate through multiple cameras, calendars, clocks, messaging apps, and security tools -- often using identical names and similar icons -- to find the apps they want to use. For a pure Android experience, get a Nexus or Pixel. With Oreo, Google keeps to its annual Android update. Accessibility services can optimize the audio experience for users with disabilities.

This change is backward-compatible, as Editable implements CharSequence. The Editable interface provides valuable additional functionality. For example, because Editable also implements the Spannable interface, you can apply markup to content within an instance of EditText. By default, the WebView shows an interstitial that warns users of the known threat.
This screen gives users the option to load the URL anyway or return to a previous page that's safe. Note: For optimal protection against known threats, wait until you've initialized Safe Browsing before you invoke a WebView object's loadUrl method. The following code snippets show how you can instruct your app's instances of WebView to always go back to safety after encountering a known threat:.
The MediaMetadataRetriever class has a new method, getScaledFrameAtTime , that finds a frame near a given time position and returns a bitmap with the same aspect ratio as the source frame, but scaled to fit into a rectangle of given width and height. This is useful for generating thumbnail images from video. We recommend using this method rather than getFrameAtTime which can waste memory because it returns a bitmap with the same resolution as the source video.
For example, a frame from a 4K video would be a 16MB bitmap, far larger than you would need for a thumbnail image.
