OpenHarmony Technology Day comprehensively interprets the 3.1 Release version of the system's basic capabilities and then upgrades

On April 25th, the OpenAtom OpenHarmony (hereinafter referred to as "OpenHarmony") Technology Day was held in Shenzhen. It conducted an in-depth interpretation of the core technologies of OpenHarmony 3.1 Release, and shared the latest ecological progress. The new OpenHarmony 3.1 Release version has greatly optimized and enhanced the basic capabilities of the system, built a strong support for the vigorous development of the open source ecosystem, and demonstrated the strong resilience of the OpenHarmony open source ecosystem.

The OpenHarmony 3.1 Release version supports the development of complex standard screen devices and complex UI applications for the first time. In the kernel layer, system service layer, framework layer and development resources & tool chain, the basic capabilities have been upgraded, marking a new turning point for OpenHarmony. stage.

OpenHarmony version continues to iterate and ecological products begin to take shape

From 1.0 to 3.1, in less than two years, the system capabilities of the OpenHarmony version have continued to develop. OpenHarmony 1.0 has a lightweight OS basic framework, OpenHarmony 2.0 supports audio, video and multi-core capabilities, and OpenHarmony 3.0 supports ArkUI framework and basic distributed capabilities, and now OpenHarmony 3.1 has new features such as complex graphics, security, telephony, and distributed enhancements.

The continuous iteration of system capabilities helps OpenHarmony to continuously enrich development resources and support a wider range of applications and device types. In terms of system capabilities, OpenHarmony 3.1 Release version has supported the development of complex UI applications. In terms of device types, the new version has supported the development of complex standard screen devices.

Up to now, more than 80 software and hardware products are passing the compatibility evaluation, and the OpenHarmony ecological products have begun to take shape. With the arrival of OpenHarmony 3.1 Release, it is believed that OpenHarmony ecological products will be further expanded.

OpenHarmony system capabilities continue to enhance distributed technology with unique characteristics

Facing the all-scenario, all-connected, and all-intelligent era, OpenHarmony has three major features: "unified OS, flexible deployment"; "hardware mutual assistance, resource sharing" ; and "one-time development, multi-terminal deployment" . Now, OpenHarmony 3.1 Release has comprehensive enhancements in the kernel layer, system service layer, framework layer, and development resources & tool chain, bringing unique functions such as distributed hardware mutual assistance capability, object-level data management capability, and distributed security framework. At the same time, the new UX design language of the new version also endows OpenHarmony with a more youthful and concise style.

At the kernel layer, the new version brings an adaptive kernel scheduling mechanism to create a base for a smooth performance experience; enriches the HDI interface to provide the system with more hardware access capabilities. In terms of system service layer, the new graphics and window framework can provide a smooth basic interactive graphics experience and animation experience; new capabilities such as encoding and decoding, video recording, and media management are added to build an end-to-end audio and video data processing platform.

Distributed technology is the unique function of OpenHarmony, and it is also the key to its competitiveness in the industry. The OpenHarmony 3.1 Release version has a new hardware resource pooling architecture, which realizes the "Hyper Terminal" hardware mutual assistance capability of the camera and the screen. The distributed camera supports the preview of the remote camera, takes pictures, and can control the zoom and camera angle of the remote camera. The screen supports screen mirroring between two devices to expand the projection capability; the distributed data object capability is added to continuously improve the development experience of global "one copy" data of various data types; the new distributed security framework is also continuously improved, Build a stronger basic platform for system integrity protection, system isolation and access control security, including distributed device mutual trust authentication, distributed user identity authentication, cross-device data security, program access control, and a trusted security environment. The version adopts hierarchical security control to further enhance system security capabilities.

The underlying capabilities of the system are enhanced, the distributed technology creates a differentiated service experience, and the comprehensive upgrade of the system capabilities of the OpenHarmony 3.1 Release version will bring rich functional experience to more devices and promote the successful implementation of OpenHarmony applications and devices.

Developers OpenHarmony application development environment and device development tools continue to upgrade

The prosperity of the ecological industry is inseparable from the contribution of every developer. Developers are the cornerstone to promote the development of OpenHarmony's open source ecosystem. The OpenHarmony 3.1 Release version brings developers a more efficient application development environment and device development tools.

The new one-stop OpenHarmony application development environment, DevEco Studio 3.0 Beta3, supports low-code development, native development, brings information center, new build tool Hvigor, two-way speed component preview, one-click automatic debugging signature and other features; convenient and efficient OpenHarmony The device development tool DevEco Device Tool 3.0 Release provides developers with a one-stop development platform and one-stop capability acquisition, enabling developers to efficiently complete device development.

Improve open source base capabilities to support the implementation of OpenHarmony ecological products in thousands of industries

ArkUI root technology, distributed root technology, kernel root technology... Why does OpenHarmony keep insisting on the innovation of root technology? With the rapid development of the global digital economy, the demand for digitalization exceeds expectations. The industry needs to explore new theories, new architectures, and reconstruct the technical base to support the sustainable development of the digital economy. The density of connections multiplied by the precision of calculations is the strength of the digital economy. Therefore, deep roots can lead to lush foliage.

With the development of the digital economy, the operating system, which is the root technology of digital infrastructure, has become a key force in digital transformation. OpenHarmony, as a digital base for pan-intelligent terminals, supports the industrial ecology of thousands of industries. Up to now, OpenHarmony has 2,000+ community contributors and 1.6 million+ community users, and is currently one of the most popular open source projects among enterprises and developers in China.

In the future, OpenHarmony will continue to invest in root technology innovation, continue to improve performance, enhance privacy security, expand distributed capabilities, and improve development efficiency to support large-scale distributed applications and full system device functions, thus effectively supporting the implementation of equipment and applications in thousands of industries. In response to the common needs of multiple industries, the OpenHarmony community will conduct continuous version maintenance to help industry software distributions build advanced productivity. OpenHarmony will continue to improve the open source base capabilities, support the vigorous development of open source ecology, better empower the industrial ecology of thousands of industries, and make greater contributions to the digital transformation of enterprises.
