Android 17 Cinnamon Bun codename confirmed

Android 17 uses Cinnamon Bun as its internal codename and signals a shift to trunk based development with a June 2026 release window.

Android 17 Cinnamon Bun codename confirmed

Google has moved to a trunk based development model for Android, and the internal codename Cinnamon Bun has surfaced for Android 17. The new approach centers on a single main code branch, with features guarded behind flags until they are ready for release. This is a major change from the previous branch based workflow and is intended to improve stability and speed of updates. The article notes that Android 14 QPR2 and QPR3 used build IDs AP1A and AP2A as part of the shift to trunk based builds, with the letter A reflecting the first year of trunk stability and later letters signaling additional platform releases. Internally, Cinnamon Bun is tied to API level 37.0, which maps to Android 17 in the public release. While users will likely see Android 17 on labels, the dessert codename will mostly live in internal documentation and beta notes. The planned release window remains around June 2026, following the pattern of summer device launches seen in recent years.

The shift to a trunk based system marks a practical bet on reliability over ceremonial branding. By keeping all work in a single main branch and gating features with flags, Google aims to reduce messy merges and late stage churn that used to slow Android updates. Cinnamon Bun as an internal codename is a cultural artifact, a reminder that much of what powers a daily phone experience happens behind the scenes. For developers and device makers, the change should translate into more predictable schedules and safer early builds. For the public, the real story is whether the new process delivers faster, more stable updates without sacrificing transparency. The dessert naming habit may fade from public view, but the core mechanics of how Android evolves—carefully, with guardrails—could become the lasting takeaway.

Highlights

The next phase will prove whether speed and stability can coexist in a faster release cadence.
