Google has released the second Android N Developer Preview, bringing with it a number of changes. This build includes the Vulkan rendering API, launcher shortcuts, and Unicode 9 emoji support. In addition, there are a number of bug fixes, like for hidden Wi-Fi networks, Direct Reply issues and more.
Google noted some of the big changes in the official announcement post:
- Vulkan: Vulkan is a new 3D rendering API which we've helped to develop as a member of Khronos, geared at providing explicit, low-overhead GPU (Graphics Processor Unit) control to developers and offers a significant boost in performance for draw-call heavy applications. Vulkan's reduction of CPU overhead allows some synthetic benchmarks to see as much as 10 times the draw-call throughput on a single core as compared to OpenGL ES.
- Launcher shortcuts: Now, apps can define shortcuts which users can expose in the launcher to help them perform actions quicker. These shortcuts contain an Intent into specific points within your app (like sending a message to your best friend, navigating home in a mapping app, or playing the next episode of a TV show in a media app).
- Emoji Unicode 9 support: We are introducing a new emoji design for people emoji that moves away from our generic look in favor of a more human-looking design. If you're a keyboard or messaging app developer, you should start incorporating these emoji into your apps. The update also introduces support for skin tone variations and Unicode 9 glyphs, like the bacon, selfie and face palm.
The new factory images are now available, and the OTA version should begin rolling out shortly.
