HarmonyOS is built upon open-source OpenHarmony (which seems to have many variants, not sure all of them are open), and OpenHarmony runs on Linux / HongMeng kernel (see OSDI '24 paper for the latter, code not open yet)
- markus_zhang 2y agoI think HarmonyOS != OpenHarmony because the later still retains compatibility with Android while the former does not. I could be wrong.
- cyp0633 2y agoThe OS compatible with Android apps is HarmonyOS (<5.0), which you can literally think of as Android + some (maybe much) Huawei stuff. The thing based on OpenHarmony is sometimes referred to as HarmonyOS Next / 5.0, and some of those having upgraded to HMOS 5.0 are always complaining its compatibility in Chinese communities. Huawei always invents so many names so that people often confuse them.
- jauntywundrkind 2y agoHuweii's Harmony NEXT came about shortly after OpenAtom formed, which is sort of the Linux Foundation of Harmony. NEXT definitely has a lot of new & rebuilt aspects of Harmony, seems unlikely to be compatible or really the same; it's a major shift with new kernels & all.
