Ahead of the IO conference, Google is surprisingly making the developer preview of the Android N available for Nexus devices. The release of a WIP (work-in-progress) build is to incorporate developer feedback earlier in the product-development life cycle.
The most important inclusions are multi-window, which will be a game-changer once it gets incorporated into consumer models, direct reply as well as bundled notifications, improved Java 8 support and an overall focus on better efficiency in terms of resource usage.
The build will also be available for end users via an OTA (Over-The-Air) update after registering here. However, Google doesn’t recommend it since it doesn’t feature regular functionality.
