What’s new in Android N Developer Preview?
Multi-window – This new multitasking feature lets users view two apps or Activities at the same time, with the system resizing them as needed to fit the device or tablet screen. All apps targeting Android N are resizeable unless they opt-out, so make sure your layouts and resources are optimized.
Bundled notifications – You can use the Notification.Builder.setGroup() method to group your app’s notifications together for easier scanning.
Direct reply notifications – Use the RemoteInput notification API to enable users to respond quickly to notifications, without leaving the notification shade.
Efficiency – Adapt your apps to use Doze to save even more power in Android N. There are also new behaviors in Project Svelte, aiming to reduce the memory needs of Android.
