Google's Project Treble, introduced with Android 8.0 Oreo, addresses a longstanding challenge in the Android ecosystem by restructuring the platform's architecture. The primary purpose of Project Treble is to expedite and simplify the process of delivering Android updates to devices, ultimately improving the fragmentation issue.

Traditionally, updating Android devices required collaboration between device manufacturers (OEMs), chipset manufacturers, and carriers. This intricate process often led to delays and, in some cases, devices being left without the latest updates. Project Treble aims to streamline this by separating the underlying Android operating system framework (the "vendor implementation") from the vendor-specific customizations and drivers.

With this separation, OEMs can now update the Android framework without waiting for chipset manufacturers to provide updated drivers. This modular approach significantly reduces the dependencies involved in the update process, enabling faster and more efficient deployment of Android updates.

Project Treble benefits both device manufacturers and end-users. Manufacturers can more easily adapt new Android versions to their devices, reducing development time. Users, in turn, receive timely access to the latest security patches, features, and optimizations, addressing one of the historical challenges associated with Android's update ecosystem.
