Google  has   previewed the next   Android -- 8.0 Oreo  
August 26 2017:Google’s next version of Android is called Oreo and is coming to smartphones and tablets in the near future. Google has announced that it has pushed the final version of Android 8 Oreo out to the Android Open Source Project, the underlying software that the Android loaded on smartphones and other devices is built on. Google’s Pixel and Nexus handsets will also soon see the update, with beta programme participants receiving it first. Here are the key  new features:
Faster Performance and Improved battery: The new update boots your tasks two times faster, which means no lags. For longer battery life, the overlaying apps running in the background and the apps that are less used,  close automatically. Oreo will automatically delete cache if your device becomes slow.
Multitask: A new picture-in-picture feature lets you open video apps like YouTube, Netflix, Duo, while you are working on any other app.
Notifications: Now you can organize and customize your notifications according  to how you  view them,  and decide on a particular sound or vibration for any particular notification. You can also snooze them up to 2 hours.  .
AutoFill and Smart Text Select: Jump into new apps directly from the browser; no installation needed. When you select a text, the app associated with it will automatically pop-up. For example, a selected phone number will get phonebook app or an address will get you Maps. Also, you can choose to auto-fill your log-in credentials, so you don’t have to remember every time.

Sameer Samat, VP of product management for Android and Google Play, described the operating system as “smarter, faster and more powerful than ever”.
“It comes with new features like picture-in-picture and Autofill to help you navigate tasks seamlessly. Plus, it’s got stronger security protections and speed improvements that keep you safe and moving at lightspeed. When you’re on your next adventure, Android Oreo is the superhero to have by your side (or in your pocket!),” he wrote in a blog post
