HDC 2021: Huawei officially releases the developer preview of HarmonyOS 3 | Building a new cornerstone for billions of connections

On October 22, 2021, Beijing time, the Huawei Developer Conference 2021 (HDC Together) was held in Songshan Lake, Dongguan, and the HarmonyOS 3 developer preview was officially released.

"HarmonyOS continues to iterate and evolve to become the technical cornerstone for building billions of connections. The continuously upgraded development kit helps developers to develop more efficient cross-end development. The HarmonyOS 3 developer preview allows developers to use more and more powerful tools, Innovate on more types of terminal devices to bring consumers a new experience of intelligent connection of all things." said Gong Ti, president of Huawei's consumer business software department: "In the near future, we will bring a new programming language developed for HarmonyOS. , To make up the last link for Hongmeng's ecological infrastructure."

Each Huawei Developer Conference marks an important milestone for HarmonyOS.

In 2019, HarmonyOS 1.0 was released, which revolutionized distributed technology and verified its feasibility. In 2020, Huawei released HarmonyOS 2.0 for developers, which not only brought major upgrades to distributed capabilities, but also released smart Developer Beta version of screen, smart wearable, car and machine products. HarmonyOS 2 brings new features such as the control center and universal cards, as well as more comprehensive performance improvements and more complete privacy protection. It has been welcomed and loved by a large number of consumers, and the upgrade speed has repeatedly broken records. So far, the number of devices equipped with HarmonyOS has exceeded 150 million, making it the fastest-growing terminal operating system in history.

At this year's developer conference, Huawei continued its tradition and launched the latest version of HarmonyOS-the HarmonyOS 3 developer preview version. It reinnovated around the three core values of flexible deployment, super terminal, and multi-terminal deployment at one time. System performance and development tools were fully upgraded. .

As a new generation of smart terminal operating system, the system architecture of HarmonyOS can be deployed flexibly, allowing smart devices with different memories to communicate in the same language. The HarmonyOS 3 developer preview version brings a new visual and flexible deployment automation tool. Device developers can flexibly choose the required components of the operating system according to different hardware, so that more devices can be more easily equipped with HarmonyOS.

Distributed technology has always been the core of HarmonyOS's capabilities, allowing multiple devices to be freely combined and integrated into a hyper terminal at the system level. Each device can become a functional module of each other, achieving mutual assistance in capabilities and sharing of resources. The HarmonyOS 3 developer preview released this time brings innovative heterogeneous networking technology, allowing distributed capabilities to support more devices, better performance, and creating a more robust hyper terminal base. For example, a mobile phone, smart screen, and 4 speakers can be combined into a super terminal with 6 devices, so that mobile video can also enjoy a large screen and 5.1-channel cinema-level experience; the combination of mobile phones, tablets, and PCs brings an upgraded version of multi-screen collaboration. Three-screen collaboration improves office efficiency.

With the release of the new HarmonyOS 3 developer preview version, the HarmonyOS application and service development tool suite Family Bucket has also been fully upgraded, helping developers to complete the development of cross-end applications and services with high efficiency and low cost end-to-end. Among them, the Harmony Design System (Harmony Design System) provides design tools such as complete design specifications for multi-terminal devices, atomized adaptive layout capability plug-ins, and service card templates that support different devices, allowing different devices to achieve a consistent visual experience while maintaining the overall Consistency of design language; Ark Development Framework 3.0 (ArkUI 3.0) brings a new declarative UI framework, using TS/JS language, reducing the amount of cross-end application front-end development and design code, greatly improving efficiency and performance; Ark Compiler 3.0 (ArkCompiler 3.0) Realize cross-device unified compilation, which can run across terminals with only one compilation; DevEco Studio 3.0 brings high-efficiency coding, cross-terminal collaborative debugging, multi-device integration testing and other tool upgrades, effectively improving the efficiency of cross-terminal application development ; HarmonyOS SDK opens 6000+ TS/JS API capabilities to support efficient development of cross-terminal distributed experience. The ability of one-time development and multi-terminal deployment helps multiple global head applications such as Sina News and Wish 107.5 to quickly cover multiple devices.

At the same time, Huawei also announced that the HarmonyOS 3 Beta version is expected to be released in the first quarter of 2022. By then, developers will be provided with more complete system capabilities and development tools, which is worth looking forward to!
