Google has gone ahead and pushed out the fourth Android N developer preview this week, which means we should be nearing a public release for the still yet to be named OS update. The fourth developer preview update adds in some finalised APIs and the final SDK for developers, there will be just one more preview before Android N lands in the hands of everyone.
These finalised APIs mean that developers can get a head start in bringing their apps to the Google Play Store, meaning those inside of the Android beta program can start testing to help identify bugs.
Developers can now start pushing their app updates to those in the new developer preview and get to work on squashing bugs, checking backwards compatibility and finalising things for release. We don't know what will be in the final developer preview, but this seems to be the biggest step to getting ready for the public release.
KitGuru Says: With Android N so close to being done, it would also make sense for Google to decide on a name some time soon. Things kicked off a little early with Android this year, so we still aren't sure if the final version will come out alongside new Nexus devices in October or earlier at the end of the Summer.
