Open source HarmonyOS system system can make a phone call! OpenHarmony is getting closer and closer to the mobile phone OS.

Electronic enthusiast network reports (text/Huang Jingjing) Recently, experts from the OpenHarmony community even released a video. In the video, it is mentioned that using the Herun DAYU200 development kit, equipped with OpenHarmony3. 1 release version, can make calls on the dial-up interface, which also means that this new version is more and more like a mobile phone.

Since Huawei's mobile phone was equipped with HarmonyOS system, the voice of domestic mobile phone operating system is getting higher and higher. Due to competition, other mobile phone manufacturers did not directly adopt HarmonyOS system. Under the development trend of independent operating system of the Internet of Everything, OpenHarmony may be another big choice.

OpenHarmony is an open source project hatched and operated by the Open Atomic Open Source Foundation. Its goal is to build the operating system framework and platform of intelligent terminal equipment in the era of full scene, full connection and full intelligence, and promote the prosperity and development of the Internet of Everything industry.

Of course, OpenHarmony was originally donated by Huawei.

In September 2020, the Open Atomic Open Source Foundation accepted the code related to the basic capabilities of the intelligent terminal operating system donated by Huawei, and then opened the source, and named the open source project "OpenAtom OpenHarmony" according to the naming rules.

HarmonyOS OS released by Huawei in August 2065438+2009 can also be said to be a commercial version of its own brand HarmonyOS system based on the basic capabilities of OpenHarmony.

Similarly, the operating system developed based on OpenHarmony in the past two years is also oriented to household appliances, industry, finance and other fields.

For example, on June 4, 20021,10, Midea released Midea's Internet of Things operating system 1.0, which was jointly launched by Midea and the Open Atomic Open Source Foundation. It has the characteristics of cross-platform, distribution and openness.

This is the first Internet of Things system based on OpenHarmony2.0 besides Huawei.

In addition, ChinaSoft International and Huichuan Technology released the world's first OpenHarmony industrial intelligent operating system, and * * * promoted the process of industrial intelligence based on domestic independent controllable bases.

At present, only in the field of smart phones, there is still a lack of mobile phone operating system based on OpenHarmony.

Now the development kit equipped with open harmony 3. 1 version can realize the function of making phone calls, which is believed to boost everyone's confidence in OpenHarmony's mobile phone operating system.

First, let's take a look at the hardware support of OpenHarmony3. 1. According to the standard system, the electronic enthusiast network mainly includes chips such as Hi35 16DV300 and RK3568.

Audio-visual entertainment, smart travel, smart home, such as smoking machine, oven, treadmill, etc.

According to the previous introduction, Dayu of He Run Software is a development kit supporting mobile phone for OpenHarmony 2.0 Canary. However, the calling function should be implemented in open harmony 3. 1 version.

On the software side, OpenHarmony has updated several versions since its release.

On September 10, 2020, the version of OpenHarmony 1.0 was officially launched, supporting terminal devices with memory from 128K to 128M;

On 202 1 June1day, the version of OpenHarmony 2.0 Canary was announced to be online, supporting all kinds of intelligent terminal devices with memory above 128M. Unlike OpenHarmony 1.0, OpenHarmony 2.0 covers rich media terminal devices with more than 100 megabytes of memory.

202 1 10, released by OpenHarmony.

202165438+February 31openharmony-v3.1-beta released.

OpenHarmony-v3. 1-Beta is based on OpenHarmony 3.0 LTS, and this update supports the following functions:

The basic capability of standard system OS is enhanced: CMA STA(Station, graphics) is enhanced by kernel, rendering back-end engine is added to support RenderService, short-distance communication supports basic features of STA and SoftAP, algorithm interface supports geomagnetic field, sensor-driven model is enhanced, application account information inquiry and subscription are supported, globalization features are supported, and compilation and construction support unified construction templates. Compiler runtime provides a front-end compiler tool chain for Windows/MacOS/Linux, JS runtime supports previewers, and adds six JS tripartite libraries, such as JSON processing, Eventbus, Vcard, Protobuf, RxJS and LibphoneNumber, to increase time zone management. DFX supports HiSysEvent components to provide query and subscription interfaces.

The enhanced distributed capabilities of the standard system include new features supporting distributed DeviceProfile, distributed data management supporting cross-device synchronization and subscription, distributed soft bus supporting network exchange and networking, and distributed file system supporting Statfs API capabilities.

Enhancement of the application framework of the standard system: increase the self-defined drawing ability of ArkUI and Lottie animation ability, and increase package management, implicit query and multi-hap package installation, event notification support authority management, setting notification vibration, notification sound setting and query, uninterrupted notification, session notification, etc.

The application ability of the standard system is enhanced: the input method application supports text input and horizontal screen layout display, SMS application information management, contact application call record and dial display, and settings application more settings.

Lightweight system capability enhancement: HiStreamer lightweight supports customizable media pipeline framework, Linux version init supports hot plug, and OS is light kernel &; Driver startup optimization and fast startup capability support.

Simply put, Open Harmony 3. 1 supports more capabilities, such as contact record and dial display, such as terminal devices with larger memory, which makes the optimization and function of operating system interface more and more like mobile phones.

With the goal of covering everything, OpenHarmony can run on various terminal devices. It can run not only on 100 KB-level resource-limited devices and wearable devices, but also on 100 MB-level smart home cameras and driving recorders, GB-level smart TVs and other devices with relatively rich resources. We see that the memory capacity supported by 1.0 is increasing.

In terms of mobile phones, early smartphones had 5 12MB, 1GB of memory, and later they had 3GB of memory. Now 6GB, 8GB, 12GB of memory has become the mainstream trend. To run applications, you must have available memory, such as WeChat, photo and video apps, games, etc. These applications have different memory requirements.

Although the tablet computer equipped with OpenHarmony is currently being tried out, there are actually many mobile phone chips supporting HarmonyOS system. Qualcomm Snapdragon 870 and 888 and MediaTek Tianji 720 and 800 support Huawei HarmonyOS system. It should be natural for these mobile phone chips to support OpenHarmony in the future.

When the HarmonyOS system is released, will there be doubts about the Android system? It is pointed out in the developer forum that Huawei HarmonyOS system can run Android applications, mainly because HarmonyOS system has realized the operation of existing Android Eco-application (AOSP).

The user application of OpenHarmony is developed based on the newly designed OpenHarmony API/SDK, which can run on the system developed based on the OpenHarmony open source project and can flow seamlessly between multiple terminals.

The OpenHarmony program framework only supports the running of OpenHarmony user applications, and does not support the running of user applications developed based on Android API/SDK.

So there is no such thing as an "Android case" in OpenHarmony. Instead, developers are encouraged to develop applications belonging to OpenHarmony.

In terms of prospering the open source ecology, at a meeting at the end of last year, Zhu, head of the ecological construction team of the OpenHarmony project team, said: In the future, OpenHarmony will carry out in-depth cooperation with mainstream chip manufacturers and gradually realize the code entering the backbone of the community. The OpenHarmony project team will provide special technical support jointly with member units and working groups, and it is expected to reach in-depth cooperation with 20 mainstream chips before the end of September 2022. With the mainstream chip code entering the backbone, there will be more OpenHarmony development boards in the future, which will integrate the needs of various industries, accelerate the technological evolution and promote the presentation of various terminal products in various industries.

Summary:

OpenHarmony aims to cover everything, and smartphones are inevitable, which is also eye-catching. In fact, OpenHarmony 2.0 has all the capabilities to support smart phones, including libraries and API interfaces. 3. The function optimization of1further enhances the functions of smart phones. At present, it is not known which mobile phone manufacturers or third-party manufacturers will take the lead in launching the smartphone operating system based on OpenHarmony.
