Fuchsia already runs Java code with Android's DalvikVM

Ok I am not an Android User and I dont follow Fuchsia closely, but I thought DalvikVM was discontinued on Android? And why having Java running on DalvikVM, which we fully expected to do so, is news worthy? What are the context here?

DalvikVM probably can still run a lot of Android apps/power Android development. ART probably requires OS features that aren't implemented yet to do the JIT safely. I'm sure this is the first step to enable parallel development so that people can start developing Android apps on Fuschia while the OS team works on support to get ART running.

The context is replacing the Linux part of Android with Fuschia or at least letting Fuschia share with Android's userspace SW ecosystem even if Android continues to use Linux.

Way off target (sorry) but I wonder when consumer Chromebook-like devices running Fushia will be generally available.

It is partly because of some dissatisfaction with Apple that I have been looking kindly at Chromebooks. For the price of a magic keyboard cover for an iPad Pro, I bought a Lenovo Chromebook last year (including a keyboard cover with trackpad and pen stylus) that does fine for enjoying all types of media, and if I don’t run anything else then the Linux container system is adequate for some light weight development.

If Fushia ends up being good, I look forward to something like a Chromebook that uses it.

Dalvik is gone, it is all ART now, the name stayed for compatibility purposes.

==> com.android.art.debug

Currently it is the Nest OS, it remains to be seen when it will move beyond that.

Android Things nee Brillo, didn't last long after being released with hype.

You are better off buying a proper Linux laptop from an Linux OEM like Tuxedo.

So you already have your ChromeOS, just by starting Chrome. :)
