First Preview of Android N: Developer APIs & Tools
Posted by Dave Burke, VP of Engineering Today weâ€™re happy to announce a Developer Preview of the N release of Android! Weâ€™re doing something a little different this year by releasing the preview earlyâ€¦ really early. By releasing a â€œwork in progressâ€ build earlier in development, we have more time to incorporate developer feedback. Also, the earlier preview allows us to hand off the final N release
