HarmonyOS NEXT (Chinese: 鸿蒙星河版; pinyin: Hóngméng Xīnghébǎn) is a proprietary distributed operating system and a major iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system is primarily aimed at software and hardware developers that deal directly with Huawei. Unlike the standard HarmonyOS and the global market EMUI, it does not include Android's AOSP core and is incompatible with Android applications.
HarmonyOS NEXT both discards the common Unix-like Linux kernel and replaces the previous multikernel system with its own bespoke HarmonyOS microkernel. The rich execution environment (REE) version of HarmonyOS microkernel is placed at its core with a single framework as kernel mode. The OS shares lineage with the lightweight LiteOS real-time operating system for resource-constrained devices like smart wearables and IoT products.
