Android O Developer Preview now available to download
Android O Developer Preview can be installed on the following devices: Google Pixel, Google Pixel XL, Google Pixel C, Nexus 6P, Nexus 5X, and Nexus Player. You can download Android O Developer Preview system images via the first source link below, while release notes (including a lengthy list of bugs and issues) can be found at the second source link.
For now, it's not clear what final name Android O will have, though it may be Android 8.0 Oreo. Regardless of the final name, here are some of the new features that this next iteration of Android will bring:
- Enhanced notifications (with users getting "fine-grained control over different kinds of notification")
- App background limits (for improved battery life)
- Picture in Picture (PIP) display - enabling actions like watching a video while chatting or using other apps
- Adaptive icons
- Wide-gamut color for apps
- Support for high-quality Bluetooth audio codecs
P.S.: The yellow thingie that you're seeing above seems to be the official Android O logo!
