Thank CTOnews.com netizen Mo Luo for his clue delivery! CTOnews.com, April 19, the Open Atomic Open Source Foundation OpenHarmony developer Conference 2023 (referred to as "the conference") is held today. The conference is under the guidance of the Open Atomic Open Source Foundation, sponsored by the working Committee of the OpenHarmony Project Group, and supported by Huawei, Kaihong Zhigu, Wanlihong, Shenkaihong, Chengmai Technology, Jiulian Science and Technology, run Kaihong, Honghu Wanlian, Youbo Terminal, Olympic thinking and other units. OpenHarmony 3.2 Release version was released for the first time on the site, interpreting the technical features of the new version, and sharing the landing achievements of partners' OpenHarmony-based development practices, community ecological progress, industry distributions and solutions.

Up to now, there are 51 co-builders and more than 5100 co-builders in OpenHarmony community, with a total code volume of more than 100 million lines, Huawei, Shenkaihong, Softong Power, Runhe Software, Jiulian Technology, Youbo Terminal, six 100-person code contribution units, more than 260 software and hardware products have passed the compatibility evaluation, covering education, transportation, finance, home, security and other industries.

After the iteration of 5 Beta versions, OpenHarmony 3.2 Release version was officially released, which further improved the system capability and comprehensively enhanced the experience of complex devices with screens.

In terms of system fluency, the OpenHarmony 3.2 Release version has a "visible" improvement. This is mainly due to the comprehensive optimization at the architecture level and the introduction of many new technologies, including ArkUI minimization update technology, parallel fast startup architecture, RenderService unified rendering architecture, high-performance ArkTS engine, infrastructure performance optimization, etc., to achieve smooth interaction, natural ease, rich dynamic effects and global consistency.

According to reports, the OpenHarmony 3.2 Release system is fluent enough to support the development of complex devices with screens in various industries. Beijing Wanlihong Science and Technology shared the landing cases of their tablet computers based on OpenHarmony and a number of commercial rich devices with screens, as well as the practice of government ecology based on OpenHarmony.

In the function of the system, the new version is constantly improved. Among them, HDF supports more than 800 HDI standardized device interfaces; the Stage model further improves the introduction of OpenHarmony application running rules and background running model from a system point of view; the distributed security and privacy protection basic platform for system integrity protection, isolation and access control is also greatly improved; at the same time, in terms of supporting application development, the new version of API 9 has 18000 + ArkTS API, which is enough to support the development of large and complex applications.

JD.com shared the application development practice and development planning based on OpenHarmony. By trying OpenHarmony component-based multi-projects, the collaborative development efficiency of large-scale App is improved, and the overall project compilation time is reduced by more than 70%. At the same time, the dynamic cross-end scheme of JD MCube developed by JD.com has adapted to OpenHarmony, and JD.com will continue to carry out large-scale App engineering transformation based on OpenHarmony in the future.

In addition, in terms of support for extremely high-performance applications, by providing NAPI and mixed development capabilities, rich Native API, TaskPool parallel development frameworks, DevEco Insight real-time performance analysis tools, etc., OpenHarmony 3.2Release system is open enough to support the development of extremely high-performance frameworks and applications. Cocos has completed the OpenHarmony adaptation of the open source game engine Cocos 2dx, and the Kaixiaole game application developed based on the Cocos-2dx engine has been able to run smoothly.

The Unity local engine in China will be launched this year. The local engine improves rendering performance and quality, and can deeply support mobile devices. At the same time, the engine has been able to support OpenHarmony system. In the future, Unity China will fully support the domestic operating system OpenHarmony.

At the level of distributed technology, the new version supports the automatic selection of transmission channels of distributed soft bus, and further optimizes and improves the ability of distributed screen, distributed data technology and multi-terminal deployment at one time.

Tencent Sogou Input shared the development practice and landing cases based on OpenHarmony distributed technology. With the development of OpenHarmony distributed technology, Sogou Input can realize the characteristics of multi-terminal UI adaptation, cross-screen linkage, free flow, computing cooperation, distributed data synchronization, multi-form and multi-ability of input method, etc.

The Release version of OpenHarmony 3.2 improves the development efficiency. DevEco Studio provides a new set of development kits, and the efficient compilation and construction tool Hvigor supports fine-grained parallel compilation and task-level incremental compilation; the scene performance tuning tool DevEco Insight provides a scenario tuning template according to typical performance problems; runtime function hot overloading technology saves developers' waiting time, and code changes are immediately apparent. The ability of visual development and debugging has also been further improved. At the same time, developer materials make it easier for developers to use by optimizing document architecture and content logic; in addition, developers are provided with rich code samples and high-frequency three-party libraries and other learning resources, and the OpenHarmony application development system has been basically completed.
