<h4 id="">New feature</h4>
<h4>Android N final APIs</h4>
<p>Description of new feature.</p>
<p>
Developer Preview 4 includes the <strong>final APIs</strong> for the upcoming
Android N platform. The new API level is 24.
</p>
<h4>Play publishing</h4>
<p>
You can now publish apps that use <strong>API level 24</strong> to Google
Play, in alpha, beta, and production release channels.
</p>
<h4>Android Studio and tools updates</h4>
<p>
Along with Developer Preview 4 we’re providing the <strong>final API 24
SDK</strong> to be used with Android Studio 2.1.2 and higher. In addition,
we’re releasing updated Developer Preview 4 system images for the emulator to
help test your apps.
</p>
<p>
As new updates roll out for Android Studio, you should see minor improvements in
the new project wizards and AVD manager as we add enhanced support for API 24.
These are primarily cosmetic changes and should not stop you from getting
your app ready for an update in the Play store.

<h4 id="dp4-fixes">Fixes for issues reported by developers</h4>
<p>
A number of issues reported by developers have been fixed, including:
</p>
<ul>
<li><strong>TODO</strong>
</ul>
<li>In previous versions of Android, an app activates with all of its locale
resources loaded before locale negotiation begins. Starting in Android N DP4,
the system negotiates resource locales individually for each resource object
before the app activates.
</li>
<p>For the full list of fixed issues, see <a href="https://goo.gl/6uCKtf">the
issue tracker</a>.</p>
<li>As announced at Developer Preview 3, we’ve deferred the Launcher
Shortcuts feature to a later release of Android. In Developer Preview 4,
we’ve removed the Launcher Shortcuts APIs.
</li>
<li>We’ve changed the BLE Scanning behavior starting in DP4. We’ll prevent
applications from starting and stopping scans more than 5 times in 30
seconds. For long running scans, we’ll convert them into opportunistic scans.

<!--
<h4>Product area</h4>
<h4>Stability</h4>
<ul>
<li>Description of bug</li>
<li>Users may encounter system instability (such as kernel panics and
crashes).
</li>
</ul>
-->
<h4>Launcher</h4>
<ul>
<li>The default launcher’s <strong>All Apps</strong> tray may become
unresponsive after cycling the screen off and on. Returning to the
homescreen and relaunching the <strong>All Apps</strong> tray may resolve
this issue.
</li>
</ul>
<h4>Setup Wizard</h4>
<ul>
<li>Crash on selecting "Not now" in "Set up email" screen.
</li>
</ul>
<h4>Media</h4>
<ul>
<li>Media playback may be unreliable on Nexus 9 and Nexus Player, including
issues playing HD video.
</li>
<li>Occasional freeze when running the YouTube app with other apps in
multi-window mode on Pixel C devices. In some cases hard reboot is required.
</li>
<li>Apps may have issues playing some Widevine DRM-protected content on Nexus
9 devices.
</li>
<li>Issues handling VP8 video on Nexus 9 devices.
</li>
</ul>
<h4>External storage</h4>
<ul>
<li>Apps may become unstable when the user moves them from internal storage
to adoptable external storage (this can include SD card or devices attached
over USB).
</li>
</ul>
<h4>Screen zoom and multiple APKs in Google Play</h4>
<ul>
<li>On devices running Android N, Google Play services 9.0.83 incorrectly
reports the current screen density rather than the stable screen density.
When screen zoom is enabled on these devices, this can cause Google Play to
select a version of a multi-APK app that’s designed for smaller screens. This
issue is fixed in the next version of Google Play services and will be
included in a later Developer Preview release.
</li>
</ul>
<h4>Vulkan support and multiple APKs in Google Play</h4>
<ul>
<li>On devices running Android N, Google Play services 9.0.83 currently
reports Vulkan support but not Vulkan version. This can cause Google Play to
select a version of a multi-APK app that’s designed for lower Vulkan support
on devices with higher version support. Currently, the Google Play Store does
not accept uploads of apps which use Vulkan version targeting. This support
will be added to the Google Play Store in the future and fixed in the next
version of Google Play services (to be included in a later Developer Preview
release). Any N devices using the version of Google Play services 9.0.83 will
continue to receive versions of apps targeting basic Vulkan support.
</li>
</ul>
<h4>Accessibility</h4>
<ul>
<li>Switch access doesn't allow user to navigate web pages in Chrome.
</li>
<li>Accessibility issues for talkback users with notification dismissal, and
wifi selection screen.
</li>
</ul>
<h4>Android for Work</h4>
<ul>
<li>Currently, CA certificates provisioned through {@link
android.app.admin.DevicePolicyManager} are not
available to profiles other than the primary user/profile due to a preload
issue. For example, this could prevent a user from connecting to a trusted
server when in a Work profile. This issue will be resolved in the next
Developer Preview.
