Google have been working on it's Fuchsia OS for some years now (since 2016) and it has been gradually gaining progress, though we are yet to see it start rolling out for devices, news regarding the OS development keeps pouring in.
According to a new file spotted by 9to5Google posted on Android's open source project website, Fuchsia OS will use a special version of ART or Android Runtime to run android applications.
"These targets are used to build ART for Fuchsia," the REDAME file said, adding that the version of Android Runtime will be installable on any Fuchsia device using a .far file package.
"They differ from usual android devices as they do not target specific hardware. They will produce a fuchsia package (.far file)," the file read.
Though it is still unclear how Fuchsia will use the Android Runtime, what we know for certain is that Fuchsia will be able to run Android applications, and the OS will be able to run on PCs, mobile phones, and tablets.
One of the major reasons why Google wants Fuchsia OS to be able to run Android apps is to make it easy for Android users to switch to the new platform when Fuchsia OS finally launches.
