>Do you really think people at the FOSDEM don't know this?
Yes, as such a comment wouldn't make sense if they did as Android is the consumer operating system with the highest market share.
>And saying that android use the linux kernel is honestly close to saying that mac os use Unix
It's no different than saying that Ubuntu uses the Linux kernel.
>Plus the userland and systems api are fully google proprietary
No, you can find open source code for userland and system apis at https://cs.android.com/
>you couldn't just make a android app work "on linux".
They already do as Linux is the kernel for Android.
