There are more exciting features packed into Android O such as
Web View enhancements: Android O enables the multi process mode for Web View components from Nougat as the default and adds an API so that developers can handle their own errors and crashes.
This makes applications that use web development languages better stability and security, and users will benefit if developers enable Google Safe Browsing for remote URLs.
Connectivity:
Android O brings some changes to the way our devices communicate with other devices. Welcome changes include:
• High-quality Bluetooth audio through the Sony code. Your favorite songs will sound even better through Bluetooth connections.
• NAN (Neighborhood Aware Networking) connectivity using the Wi-Fi Aware specification. Devices with supported hardware can communicate with each other using Wi-Fi without a central access point.
• Telecom framework introduces new ways for third-party calling apps to work with each other and with your carrier’s special features. New APIs now support apps that don’t need to use the universal system phone app to display calling information and this data can be displayed and controlled over Bluetooth.
Wide-gamut color for apps:
Developers building applications for Android O on devices that support wide-gamut color can now leverage those displays.
Apps like photo editors and image viewers can make use of this, and the developers simply need to enable a setting letting the system know the app is wide-gamut color aware and embed a wide floor profile.
Adaptive Icons:
Pixel launcher brought adaptive icons, and now Android supports them system wide and natively.
Options can be given for different shaped masks that define the outside border and icons can be animated. Adaptive icons will be supported in the launcher, shortcuts, device Settings, sharing dialogs, and the app overview screen.
