New feature

Android N final APIs
-
Description of new feature.
+
+ Developer Preview 4 includes the final APIs for the upcoming
+ Android N platform. The new API level is 24.
+
+
+
Play publishing
+
+
+ You can now publish apps that use API level 24 to Google
+ Play, in alpha, beta, and production release channels.
+
+
+
Android Studio and tools updates
+
+
+ Along with Developer Preview 4 we’re providing the final API 24
+ SDK 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.
+
+
+
+ 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.

Fixes for issues reported by developers
-
-
- A number of issues reported by developers have been fixed, including:
-
-
+
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.
+

-issue tracker.
+
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.
+
+
+
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.
+
+
+
The Multi-Window
+ android:minimalHeight and android:minimalWidth
+ attributes have been renamed to android:minHeight and
+ android:minWidth.
+
+
Known Issues
-
+
Launcher
+
+ - The default launcher’s All Apps tray may become
+ unresponsive after cycling the screen off and on. Returning to the
+ homescreen and relaunching the All Apps tray may resolve
+ this issue.
+
+
+
+
Setup Wizard
+
+
+ - Crash on selecting "Not now" in "Set up email" screen.
+
+
+
+
Media
+
+
+ - Media playback may be unreliable on Nexus 9 and Nexus Player, including
+ issues playing HD video.
+
+
+ - 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.
+
+
+ - Apps may have issues playing some Widevine DRM-protected content on Nexus
+ 9 devices.
+
+
+ - Issues handling VP8 video on Nexus 9 devices.
+
+
+
+
External storage
+
+
+ - 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).
+
+
+
+
Screen zoom and multiple APKs in Google Play
+
+
+ - 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.
+
+
+
+
Vulkan support and multiple APKs in Google Play
+
+
+ - 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.
+
+
+
+
Accessibility
+
+ - Switch access doesn't allow user to navigate web pages in Chrome.
+
+
+ - Accessibility issues for talkback users with notification dismissal, and
+ wifi selection screen.
+
+
+
+
Android for Work
+
+
+ - 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.
+
+
+
Fixes for issues reported by developers
+
+
+ A number of issues reported by developers have been fixed, including:
+
+
+
+ - The active network state ({@link android.net.NetworkInfo#getState
+ NetworkInfo.getState()} and {@link android.net.NetworkInfo#getDetailedState
+ NetworkInfo.getDetailedState()}) might return incorrect values during some
+ restricted background scenarios
+
+
+ - Data Saver restricts the foreground MMS mobile network request
+ (bug
+ 208478)
+
+
+ - Quick settings tiles and notifications sometimes unresponsive
+
+
+ - Unable to dismiss Clock notifications
+
+
+ - Duplication of bluetooth icon and other status icons
+
+
+ - Additional bluetooth connectivity fixes
+
+
+
