Earlier today, Google had announced the release of factory images and OTA files of the Android N Developer Preview 4. Now, it has also started the actual OTA of the developer preview for users who have joined the Android Beta Program.

The Android N Developer Preview 4 is available for Nexus 5X, Nexus 6P, Nexus 6, Nexus 9, Nexus 9 LTE, Nexus Player, Pixel C and General Mobile 4G (Android One device). The build number of the update is NPD56N. The factory of NPD56N is also available for Sony Xperia Z3 with model numbers D6603 and D6653, but the full OTA images are not available for it yet.

The fourth developer preview contains final APIs of level 24. Apps supporting API level 24 can be published on Google Play in alpha, beta and production release channels. The Launcher Shortcuts APIS are now no longer available in DP4.

The BLE Scanning behavior has been modified in DP4. It will now allow apps from beginning or stopping scans over 5 times in 30 seconds. Scans that can run for longer duration will be converted to opportunistic scans. The DP4 also contains renamed attributes for Multi-Window. The new attributes are android:minHeight and android:minWidth.

Google is yet to announce the official name for Android N. Rumors have it that it may launch as Android Nutella as an image tweeted by Hiroshi Lockheimer, the senior VP in charge of Android with Google showed that he was searching for Nutella on Google Chrome browser.

The Demo Mode feature of Android usually shows a clean screen without any notification icons on the status bar along with current version of the operating system as its time. Since the Demo Mode in DP4 now shows the timing as 7.0, it indicates that the version of Android N will be numbered as 7.0, 9to5Google reported.
