+ + + +

New in DP3

+

VR Mode for Android

-

API changes

+

+ Android N adds platform support and optimizations for a new VR Mode to let + developers build high quality mobile VR experiences for users. There are a + number of performance enhancements, including access to an exclusive CPU core + for VR apps. Within your apps, you can take advantage of intelligent + head-tracking, and stereo notifications that work for VR. Most importantly, + Android N provides for very low latency graphics. +

+ +

+ For more information, see the Google VR SDK for Android. +

+ +

Sustained performance mode

+ +

+ Android N includes optional support for sustained + performance mode, enabling OEMs to provide hints on device performance + capabilities for long running applications. App developers can then use these + hints to tune applications for a predictable, consistent level of device + performance over long periods of time. App developers can try out this new + API in the developer preview on Nexus 6P devices only. +

+ +

Multiprocess WebView

+ +

+ Starting with version 51 in Android N, WebView will run web content in a + separate sandboxed process when the developer option "Multiprocess WebView" + is enabled. The WebView team is looking for feedback on compatibility and + runtime performance in N before enabling multiprocess WebView in a future + version of Android. In this version, regressions in startup time, total + memory usage and software rendering performance are expected. +

+ +

+ If you find unexpected issues in multiprocess mode we’d like to hear about + them. Please get in touch with the WebView team by + filing a bug. +

+ +

Keyboard Shortcuts helper

+ +

+ Android N lets users press Meta+/ to trigger a Keyboard + Shortcuts screen that displays all shortcuts available both from the + system and from the app in focus. Developers can add their own shortcuts or + trigger the Shortcuts screen from their apps. See Keyboard + Shortcuts helper for details. +

+ +

FrameMetrics API

+ +

+ DP3 introduces a new FrameMetrics API + that allows an app to monitor its UI rendering performance by exposing a + streaming pubsub API to transfer frame timing info for the application’s + current window. FrameMetricsListener can be used to measure + interaction-level UI performance in production with higher granularity and + without the need for a USB connection. +

Feature and API changes

-
Number-blocking
-
If an unauthorized user attempts to block or unblock a number, the operation - now fails with {@link java.lang.SecurityException}. (Previously, the - operation threw {@link java.lang.UnsupportedOperationException}.)
+
+ Launcher Shortcuts and the Launcher Shortcuts API +
-
Quick - Settings Tile API
-
The system now uses the activity's metadata to decide on the tile mode. +
+ We’ve decided to defer this feature to a future release of Android. We plan + to remove the Launcher Shortcuts APIs (ShortcutManager and others) from the + public Android N API starting in the next developer preview. +
+ +
+ WebView Javascript run before page load +
+ +
+ Starting with apps targeting Android N, the Javascript context is reset + when a new page is loaded. Currently, the context is carried over for the + first page loaded in a new {@link android.webkit.WebView} instance. + Developers looking to inject Javascript into the {@link + android.webkit.WebView} should execute the script after the page has + started to load. +
+ +
+ WebView Geolocation on insecure origins +
+ +
+ Starting with apps targeting Android N, the geolocation API will only be + allowed on secure origins (over HTTPS.) This policy is designed to protect + users' private information when they're using an insecure connection. +
+ +
+ Data Saver +
+ +
+ Starting in Developer Preview 3, apps can use use an intent to display a + system dialog that lets the user directly add the app to the Data Saver + exemption whitelist. See the Data Saver + documentation for details. +
+ +
+ Number-blocking +
+ +
+ If an unauthorized user attempts to block or unblock a number, the + operation now fails with {@link java.lang.SecurityException}. (Previously, + the operation threw {@link java.lang.UnsupportedOperationException}.) +
+ +
+ Quick Settings Tile + API +
+ +
+ The system now uses the activity's metadata to decide on the tile mode. (Previously, tile mode was determined by the return value of TileService.onTileAdded().) For more information, see - TileService.META_DATA_ACTIVE_TILE in the downloadable - API Reference. + TileService.META_DATA_ACTIVE_TILE in the downloadable API Reference.
