Android N available the Developer Preview 2

Google releases the second Android Developer Preview N (NPC91K) in just over a month away from the first version.

Access continues to be reserved for holders of a Nexus device: supported 5X Nexus, Nexus 6, 6P Nexus, Nexus 9 and Pixel C.

The innovations introduced by the new release of Android N include:

As is known, by reducing the overhead of API (reduction of GPU workload to process requests made by bees) promise a major increase in performance compared to OpenGL ES libraries. With the Developer Preview 2 Android, Vulkan is an integral part of the platform, and developers can start using Vulkan Developer Tools .
Shortcuts in the launcher. The app supports the shortcuts that the user can freely position in the launcher. Shortcuts trigger specific actions or sections of the app, allowing, for example, to quickly send a message, play the next episode of a TV series in an app like Netflix, etc.
Emoji support Unicode 9. Google has introduced a new design for the emoji that become less generic and more "human". Developers can then begin to incorporate new emojii in messaging app. Below are some examples provided by Google.

M Android Developer Preview 2 also brings an update of the API with the aim of refining capabilities previously introduced. Google specifically refers to APIs that let you manage the multi-window mode and notifications, but the list is even more extensive. These are changes that can not be immediately perceived end user side, but important to advance the development path of the operating system.
