I would argue that Android has very little to do with Linux. You don't even have to go far into the quirks of the userland, the kernel is a heavily modified flavor of it to which the linux documentation simply does not apply, or not really accurately.
With recent versions it might be better now, but holy guacamole it is very bad in those before that, basically it's filled with nonstandard modifications (well, probably depends on what you call standard, though…)
android works on upstream kernel fine. in fact, you can even run a linux chroot inside of a booted android perfectly fine. android, especially newer ones, really arent that far off normal linux at all anymore, hell Waydroid is literally running android inside of an LXC container with some patches to get proper integration with the host working
