HarmonyOS : Open source operating system for smartphones and smart devices

Huawei has finally announced HarmonyOS. HarmonyOS is an open source operating system for smartphones, tablets and smart IoT devices such as smart speakers, computers, smartwatches, wireless earbuds, cars and more.

CEO Richard Yu said that the HarmonyOS is the first microkernel-based distributed OS for all scenarios and was created with four major building blocks in mind, ensuring a new generation OS that is best suited for the digital world today. The HarmonyOS microkernel can be scaled on demand for wider system security. The Microkernel does away with root access to protect system security from the source compared to Android.

It is built with a deterministic latency engine that gives a smooth interactive experience, so the latency is at a minimum; bringing fluid interactive experience to the maximum. HarmonyOS will have a verified TEE (Trusted Execution Environment) which improves connected security across multiple smart devices in a connected all-scenario world.

HarmonyOS can be nested to adapt flexibly to any device to create a seamless cross-device experience. Developed via the distributed capability kit, it builds the foundation of a shared developer ecosystem. The OS uses HUAWEI ARK Compiler with support for app development in multiple languages (Kotlin, Java, Javascript, C, and C++). The platform will support HTML5, Linux, and Android app compatibility in the future.

HarmonyOS Roadmap

HarmonyOS 1.0 in 2019 — In-house development for key modeuls based on open source framework will debut with HONOR Vision Smart TV, which will be launched in China tomorrow, August 10th.
 HarmonyOS 2.0 in 2020 — In-house development for kernel and app framework will support PCs, smartwatches, smart bands and head units.
HarmonyOS 3.0 in 2021 — Optimization in software-hardware synergy and support speakers and headsets
HarmonyOS in 2022 — Support VR glasses and other products.

Huawei CEO said it will take just a day or two to migrate from Google’s Android to the new HarmonyOS if needed, but it will stick to Google’s platform for now. HUAWEI can switch HarmonyOS anytime if it faces any issues regarding Android in the future.
