In the announcement post on the Android Developers Blog, Google notes that while last month’s dev preview included the final APIs for Nougat, this new preview gives developers the “near-final” system updates for all compatible preview devices. Below you can find a quick rundown of what’s included in this new release:
System images for Nexus and other preview devices
An emulator that you can use for doing the final testing of your apps to make sure they’re ready
The final N APIs (API level 24) and latest system behaviors and UI
The latest bug fixes and optimizations across the system and in preinstalled apps
The fifth dev preview comes in at build number NPD90G.
Both factory images and OTA zip files are now available at the links below, and over-the-air updates will start rolling out later today for folks who are enrolled in the Android Beta Program.
