Our efforts till now have been focussed on making OS updates easier and faster to deploy. The other side of this coin is supporting updates for a longer period of time, and today we’d like to provide an overview of the changes we are making to help our partners achieve this.
. As a part of this split, the Android OS framework guarantees backward compatibility with the vendor implementation, which is checked through a standardized compliance test suite - (GSIs) that are built from AOSP sources, and are guaranteed to be backwards-compatible with the previous 3 versions of vendor implementations, in addition of course to the current release—for a total span of four years. Devices launching with the new Android release must have vendor implementations compatible with that GSI. This is the primary vehicle for reducing fragmentation within the OS framework. While we allow and encourage our partners to modify the framework itself, the modifications post-Treble must be done in a way that reduces upgrade costs from one version to the next.
Besides the reuse of a vendor implementation across OS updates, the Treble architecture also facilitates the re-use of the same OS framework code across different vendor implementations.
Considering that SoC providers have dozens of SoC models at any point of time, the full picture looks closer to this:
This change is taking effect with all SoCs launching with Android 11 and later. By working closely with Qualcomm to offer an extended period of OS and security updates, we are looking forward to delivering the best of Android to our users faster, and with greater security for an extended period of time.
