Google recently blogged disclose ， Chrome OS bottom layer will share the same technology stack with Android more widely 。
A related example is that Chrome OS has used its own Bluetooth protocol stack before, but now it has switched to Android's Bluetooth protocol stack. This conversion (from Bluez to Fluoride) not only improves the pairing speed, but also improves the Bluetooth pairing success rate and reconnection rate.
Google believes that this change will help "different devices such as mobile phones and accessories work better with Chromebook". Take the Bluetooth protocol stack as an example. Most accessories are tested for Android and mobile devices rather than Chromebook. The switching of Chrome OS can benefit laptops from existing mobile support.
Google also said:
In order to continue to introduce new Google AI functions to users in a faster and larger way, we Some Android stacks (such as Android Linux kernel and Android framework) will be used as part of the foundation of Chrome OS 。
Introducing the Android based technology stack into Chrome OS will enable us to accelerate the AI innovation pace of Chrome OS core, simplify engineering work, and help different devices such as mobile phones and accessories better work with Chrome Book.
It can be seen that Google made this change for several reasons, including Improve development efficiency And help your phone and accessories become more compatible with Chromebook. But more importantly, it can speed up the implementation of more AI functions and tools on the Chromebook platform.

In addition to search, G Suite and Gmail, for most users, Android devices are the devices that they interact most frequently with Google AI products.
Therefore, it is not surprising that Google focuses on Android for AI development. If Chrome OS can also be transformed into sharing the same underlying technology as Android, the technical difficulty and development cost of porting AI functions and tools to Chrome OS will be greatly reduced.
But you don't need to expect to see the results of this work on Chrome Book soon.
Google said that although the development work related to replacing the underlying technology of Chrome OS has begun, the update "will not be launched to consumers for a long time". Once Chrome OS is ready for major changes, Google promises to bring a "seamless" transition experience.
BTW， Last month, Google engineers demonstrated "running Chrome OS in Android virtual machine" at a private event: This activity was mainly demonstrated by Google to its Android partners who had close communication with Google. The internal code of this special Chrome OS build is "ferrochrome", which is intended to run in a virtual machine. According to the demo video, "ferrochrome" has been able to run smoothly in Google Pixel 8 - and in a virtual machine. At that time, it was speculated that this was the precursor of Android's support for Chrome OS, but later "Ferrochrome" team Clarification - said that this project aims to show the practical application of its virtualization technology (AVF), which is a "very cool challenge" and can challenge the limits of new virtualization technology. Although the result was successful, that was all. This is just a proof of concept.
