But, we see you scratching your heads through the screen, wondering how and why Cinnamon Bun. Why not something with “W” to follow Android 16 “Baklava”? Wait, Android 16 “Baklava”? It actually makes perfect sense. You can head on over to the source link for a more in-depth explanation, but here’s the gist of it. Google relatively recently switched Android development from the old branch-based model to a new “Trunk Stable” model. Instead of merging new release branches back into the stable one like before, the new model has a constantly ideally stable single main code branch with all new features, fixes and APIs developed behind “feature flags” to keep them disabled until they are ready.
You still with us? Good. The important bit here is that Google completed the migration to the new trunk-based dev model with Android 14 QPR2, and to mark the change, the build ID scheme was reset, so Android 14 QPR2 became build ID AP1A and QPR3 got build ID AP2A. The first time Google released a trunk stable build was in 2024, hence the use of the letter “A” to preface the build ID. However, presumably by that time Android 14 already had its “Upside Down Cake” name and Android 15 its “Vanilla Ice Cream” moniker, so it was too late to “restart” the names and call Android 15 something with “A”. Once the year turned over to 2025, however, the build IDs started coming out with the letter “B” and Google decided to call Android 16: “Baklava”. The next letter for build IDs is “C” and hence a dessert with “C” – enter “Cinnamon Bun”, presumably since “Cupcake” was already taken.
Of course, ultimately, the dessert name doesn’t really matter that much, especially since Google decided to move away from it as a public branding. Nowadays, it is a remnant on the development side of things. Still, it is interesting to see what sweets the Google team chooses now that it is essentially the second time around for each letter. As for Android 17, we expect it to land around June 2026.
