Now that Android 16 has been out for quite some time already, Google is working on the new OS, Android 17 . However, we don’t know too many details about the OS currently. A leak from August claimed that Android 17’s codename is “Cinnamon Bun,” continuing Google’s dessert tradition, at least internally. New findings now present strong evidence and confirm that this is indeed the internal moniker.
New evidence confirms Cinnamon Bun is Android 17’s codename
Android Authority reports that while digging through the latest 2511 Android Canary release, which is the latest preview build that offers a glimpse of future Android features, they have spotted the “first public” mention of Cinnamon Bun in Android code. The “android.os.Build now lists “CINNAMON_BUN” as a valid Android version.
“CINNAMON_BUN” has been assigned the version code “10000.” This number apparently represents the API level, a unique identifier for each Android version. Google uses API levels to describe features and behaviors, which will help developers understand what’s available and how the system-level changes may affect their applications .

But does it matter?
Google usually increments the API level sequentially for each major release. Considering Android 16 is API level 36, Android 17 could become API level 37. This will only happen when the OS reaches “Platform Stability” next year. Until then, it will be the “1000” placeholder.
Though we now have a confirmation of sorts that Cinnamon Bun is Android 17’s codename, it doesn’t change anything. Google stopped referring to Android versions by dessert names after Android 9 Pie in 2018. As for Android 17, it could launch in June 2026, so we’ll know more then.
