Android is highly coupled to Linux, and this is visible at various places in the SDK such as: https://developer.android.com/reference/android/system/Os?hl=en https://developer.android.com/reference/android/system/Os?hl... But even just behaviorally it doesn't pretend to be OS agnostic at all. Setting thread priorities isn't even abstracted, it's just "uses the Linux values for this" https://developer.android.com/reference/android/os/Process#setThreadPriority(int,%20int) https://developer.android.com/reference/android/os/Process#s... That doesn't prevent building an abstraction layer and plopping Android onto a different kernel, of course. After all that's what Microsoft did with WSL.
