At the Huawei Developer Conference 2021 held today in Songshan Lake, Dongguan, the HarmonyOS 3 Developer Preview was officially released. In 2019, HarmonyOS 1.0 came out, proposed distributed technology, and verified the feasibility. In 2020, Huawei released HarmonyOS 2.0 for developers, bringing the upgrade of distributed capabilities, and also released smart screens. The company also released the beta version for developers of smart wearable, cars, and other products. So far, the number of devices that use the HarmonyOS exceeds 150 million.
At this year’s Developer Conference, Huawei launched the latest version of HarmonyOS -HarmonyOS 3 Developer Preview. According to Huawei, HarmonyOS 3 continues to innovate around the three core values of system architecture. It focuses on the super terminal, one-time development of multi-terminal deployment, and bringing a comprehensive upgrade of system capabilities and development tools.
According to reports, as a new generation of smart terminal operating system, HarmonyOS 3 system architecture is flexible. This allows smart devices with different memories to communicate in the same language. The HarmonyOS 3 developer preview version brings new flexible deployment automation tools. Device developers can select the required components according to different hardware.
In addition, distributed technology has always been the core of HarmonyOS’s capabilities. This allows multiple devices to freely combine and merge into a super terminal at the system level. The HarmonyOS 3 developer preview also brings heterogeneous networking technology, allowing distributed capabilities to support more devices and better performance. For example, a mobile phone, smart screen, and 4 speakers can combine into a 6-device super terminal. Thus, the smartphone can take advantage of the large screen for a better experience.
HarmonyOS 3 developer preview features
With the release of the new HarmonyOS 3 developer preview version, the HarmonyOS application and service development tool suite get a full upgrade.
- Harmony Design System provides design tools that support different devices. This allows different devices to achieve a consistent visual experience while maintaining the overall design language consistency
- Ark Development Framework 3.0 (ArkUI 3.0) brings a new declarative UI framework using TS/JS language. It also reduces the amount of cross-end application front-end development and design code. This greatly improves efficiency and performance.
- DevEco Studio 3.0 brings high-efficiency coding, cross-terminal collaborative debugging, multi-device integration testing, and other tool upgrades. These effectively improve 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.
Huawei also announced that HarmonyOS 3 Beta is expected to be released in the first quarter of 2022.
