Google have made improvements in new iteration of Android. Android Oreo can apply automatic limits on what applications can do in the background in a number of key areas.
These changes will make it easier to create apps that have minimum impact on a smartphone device and battery. Background limits represent a significant change in Android battery life.
Android oreo will have new picture-in-picture functionality, which is probably one of the most useful changes.
This feature would allow users to continue watching videos on a small virtual screen while getting work done within other apps.
Apps will be able to put themselves in picture-in-picture mode. User can watch a YouTube video while sending e-mails in the Gmail app.
Android oreo can group notifications into channels, giving users greater control over their app notification categories.
Users can block or change the behavior of each channel individually, rather than managing all of the apps’ notifications together.
It is also possible to snooze individual notifications, which is seriously useful given the persistence of some Android system notifications. User can snooze notifications for 15 minutes, 30 minutes, or one whole hour.
Autofill APIs will allow your favourite password manager applications to work with the Android operating system, so you can access them like you would a third-party keyboard.
Another feature in Oreo is the addition of adaptive icons. Developers will be able to use different-shaped app icons, depending on the manufacturer’s preference.
Android's in-built manager will be improved in order to provide way to browse files without having to install an additional app.
Pixel and Pixel XL smartphones were shipped with an exclusive feature which allowed users to expand their notification tray by swiping down on the phone's fingerprint scanner.
Google will provide that fingerprint-swipe gesture to a new level in Android Oreo.
A new feature in Android oreo called Wi-Fi Aware has some enhanced functionality. Without needing to be on the same Wi-Fi network, devices running the new Android version will be able to discover one another, then create a private network between them that can allow the devices to share data among themselves.
To install apps from external sources on previous Android versions, "Unknown Sources" in Settings was there.
With Android 8.0, this setting is not available, and user has to trust individual apps before you can install APKs they have downloaded.
