Google released the Android N Developer Preview 4 (build number NPD56N) for supported devices with some significant changes and fixes. If you are signed up for the Android beta program, you will get the OTA update on all supported devices, such as Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, Nexus Player, Pixel C, General Mobile 4G (Android One), Sony Xperia Z3 (D6603 and D6653).
The fourth Android N Developer Preview brings some major changes, including the final API level 24 for the upcoming Android N platform. It means developers can now publish Android N apps with API level 24 supports on the Play Store in alpha, beta and production release channels.
Below are the some of the new changes of Android N Developer Preview 4
1. 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.
2. As announced at Developer Preview 3, the Launcher Shortcuts feature postponed to a later release of Android. In Developer Preview 4, the Launcher Shortcuts APIs have been removed.
3. In DP4, applications will be stopped from starting and stopping scans more than 5 times in 30 seconds. Long running scans will be converted to opportunistic scans.
4. The Multi-Window and Width attributes have been renamed.
