Google's Project Treble aims to make slow Android updates a thing of the past

Now, Google is taking tangible steps to reduce the overhead and quicken up those updates a bit. Ahead of I/O 2017, the Android household announced Project Treble. Touting it as the biggest change to Android's system architecture ever, PT separates the low-level code written by SoC manufacturers like Samsung and Qualcomm from the Android OS codebase. This is the very basic gist of it, and the result is that device makers can now deliver updates by updating only code relevant to the OS without further work needed from the silicon slingers.

Thus, a significant bottleneck in the update process is bypassed and new Android updates ought to be reaching devices sooner. Additionally, Google is trying to get its processor and device-making partners to bring their code changes, such as new features and bugfixes, to the common Android Open Source Project codebase.

Project Treble is part of the upcoming Android O and is already running on the Developer Preview version for Pixel phones. All devices that launch on O or get updates to it will support the program. The next Android version is coming later this year.
