On December 16, Huawei held the launch event for the HarmonyOS 2.0 mobile phone developer beta in Beijing. The company stated that HarmonyOS is a full-scenario distributed operating system designed for the era of all-connected devices. Huawei aims to work with partners and developers to create a super terminal experience for the era of all-connected devices.
Wang Chenglu, President of Huawei Consumer BG Software Department, believes that HarmonyOS is the key to the era of all-connected devices. In 2021, more than 100 million devices will become new entry points for the Internet of Things. In addition, Wang Chenglu introduced development tools for developers, including HarmonyOS design tools and DevEco Studio 2.0 Beta 3.0, significantly reducing the development difficulty for HarmonyOS developers. A single development can be adapted to devices such as phones, watches, and large screens.
In addition, the HarmonyOS 2.0 developer beta for smartphones has launched an open recruitment for online testing, and the recruited models include the P40, P40 Pro, Mate30, Mate30 Pro, and MatePad Pro.
This public beta activity is aimed at developers. The official offers two ways to participate. One is to use the remote simulator in HUAWEI DevEco Studio and download the DevEco Studio 2.0 Beta3 from the HarmonyOS official website. The second is to use the exclusive OTA upgrade. Once registration is successful, you will receive an OTA push.
The public beta adds 15,000 new APIs, supporting the development of applications for mobile phones, tablets, large-screen devices, wearables, and in-car systems. Its core features include a distributed application framework, distributed user interface controls, and the DevEco Studio 2.0 Beta3 development platform.
Sina’s mobile channel shared a hands-on video of the HarmonyOS 2.0 developer test version. Users reported that the interface of this version is no different from the Android-based EMUI 11, and it was confirmed that the new system is compatible with Android apps.
HarmonyOS 2.0 mobile phone developer beta provides the following main functions:
- Brand new mobile UI controls, adding more than 50 UI controls for developers to create HarmonyOS mobile applications, achieving a unified UI interaction experience across multiple devices.
- The HarmonyOS application framework supports fast migration, connection, and installation-free loading between mobile devices and multiple other devices.
- Provides development and compilation toolchain experiences for Windows and Mac platforms, helping developers quickly develop HarmonyOS applications.
- Provides mobile developers with over 40 sample codes to help them quickly understand and adapt to HarmonyOS interfaces and development methods.
- Open distributed capability interfaces (such as multimodal perception) support the detection of various user movement states.
- Provides a standardized input method framework and capabilities; developers can develop multiple input methods and functions.
- Provide standardized telephone system interface capabilities.
- Provide a barrier-free development framework that enables developers to easily build applications.
