+
+<p>
+  Android N integrates <a href="http://www.khronos.org/vulkan" class=
+  "external-link">Vulkan™</a>, a new 3D rendering API, into the platform. Like
+  <a href="https://www.khronos.org/opengles/" class="external-link">OpenGL™
+  ES</a>, Vulkan is an open standard for 3D graphics and rendering maintained
+  by the Khronos Group.
+</p>
+
+<p>
+  Vulkan is designed from the ground up to minimize CPU overhead in the driver,
+  and allow your application to control GPU operation more directly. Vulkan
+  also enables better parallelization by allowing multiple threads to perform
+  work such as command buffer construction at once.
+</p>
+
+<p>
+  Vulkan development tools and libraries are rolled into the Android NDK. They
+  include:
+</p>
+
+<ul>
+  <li>Headers
+  </li>
+
+  <li>Validation layers (debug libraries)
+  </li>
+
+  <li>SPIR-V shader compiler
+  </li>
+
+  <li>SPIR-V runtime shader compilation library
+  </li>
+</ul>
+
+<p>
+  Vulkan is only available to apps on devices with Vulkan-capable hardware,
+  such as Nexus 5X, Nexus 6P, and Nexus Player. We're working closely with our
+  partners to bring Vulkan to more devices as soon as possible.
+</p>

+
+<p>
+  In Android N, print service developers can now surface additional information
+  about individual printers and print jobs.
+</p>
+
+<p>
+  When listing individual printers, a print service can now set per-printer
+  icons in two ways:
+</p>
+
+<ul>
+  <li>You can set an icon from a resource ID by calling
+  <code>PrinterInfo.Builder.setResourceIconId()</code>
+  </li>
+
+  <li>You can show an icon from the network by calling
+  <code>PrinterInfo.Builder.setHasCustomPrinterIcon()</code>, and setting a
+  callback for when the icon is requested using
+  <code>android.printservice.PrinterDiscoverySession.onRequestCustomPrinterIcon()</code>
+  </li>
+</ul>
+
+<p>
+  In addition, you can provide a per-printer activity to display additional
+  information by calling <code>PrinterInfo.Builder.setInfoIntent()</code>.
+</p>
+
+<p>
+  You can indicate the progress and status of print jobs in the print job
+  notification by calling
+  <code>android.printservice.PrintJob.setProgress()</code> and
+  <code>android.printservice.PrintJob.setStatus()</code>, respectively.
+</p>
+
+<p>
+  For more information about these methods, see the downloadable <a href=
+  "{@docRoot}preview/setup-sdk.html#docs-dl">API Reference</a>.
