Android version updates are painfully facing issues for slow updates. This has been the reality ever since the operating system’s inception. By having concern over it, Google is announcing Project Treble to tackle one of Android’s biggest issues.
Starting with Android O, the OS is being re-engineered to make updates easier, faster, and less costly for manufacturers. Developers got the idea from the Compatibility Test Suite that enables them to write apps. It works across billions of phones and tablets without asking to make tweaks for each device type.
Developers designing the Project Treble with whole new architecture. In actual, Google is separating the vendor implementation, lower level software written in large part by the silicon manufacturers from Android OS.
Instead, it introduces a new vendor interface that is validated by a Vendor Test Suite (VTS), to ensure forward compatibility of the vendor implementation.
The Project Treble holds the potential to speed up the update process for end users, but probably not by a lot. Any handset manufacturer can own its features on top of the new Android release, but some of those need to rewriting.
Google says, “it’s working with its silicon and device-making partners to move some of their code changes, such as specific features for a specific network in a specific country, into the Android Open Source Project code. That means the developers of that code (say, Sony and Qualcomm) won’t need to rework those patches for every new Android iteration anymore.”
