The third Android N Developer Preview announced at Google I/O last month was the first beta stable enough for daily use. Developer Preview 4 continues on that path with final APIs and the official SDK for developers to begin publishing apps for Android N devices. We’re installing DP4 on our Nexus devices right now and updating a full list of all the new features.
Factory images and OTAs can be found at the Android Developers site. The following links below are factory images for build NPD56N. You can learn how to install Android N Developer Preview factory images using our simple guide.
Instead of flashing and wiping your devices, Google also provides download links to the same OTAs that are rolling out as we speak. You can use these if your device already has Android Developer Preview 4 for a faster update. Simply follow our guide for installing Marshmallow OTAs if you need to learn how to do this.
