Google has made Android N Developer Preview 4 available to developers and beta testers.
Google says devices that are enrolled in the beta program should be able to update to the newest preview right away. The N Developer Preview is available to the Nexus 6, 5X, 6P, 9, and Pixel C devices, as well as the Sony Xperia Z3.
In addition to releasing the preview, Google also finalized the APIs for Android N. This means developers have the complete set of tools they need in order to create apps compatible with Android N.
Developers will need to download the final SDK for Android N in order to access the finished APIs. Google says it will release Android N later this summer.
