  • Support the rapid acquisition of relevant resources during the development of OpenHarmony applications, and improve the efficiency of information acquisition.

Provide multi-device engineering templates:

Based on the declarative development paradigm and web-like development paradigm, Huawei DevEco Studio 3.0 beta 3 provides OpenHarmony developers with multi-device project templates and supports cross-device development. When developing an application/service, after the developer creates a project according to the wizard, DevEco Studio will automatically generate sample code and related resources. After the project is synchronized, it can be run directly. The developer does not need to type code from scratch, and can quickly get started.

Efficient code editing:

In the stage of writing application or service code, using common code skills can improve coding efficiency. DevEco Studio provides various common skills such as code highlighting, code folding, and code formatting, and supports Lenovo completion, code jumping, code verification, etc., to achieve efficient code editing.

Support visual interface UI development:

OpenHarmony low-code development provides an efficient visual design method, has rich UI interface editing functions, its interface and logic are separated, supports free drag & drop of various components, quick preview effects, what you see is what you get. It supports cards Zero-code development effectively improves the efficiency of building UI interfaces. Developers can choose to enable Super Visual when creating a project, enable the low-code development function, and open the “.visual” file in the project directory structure to design and develop the visual layout of the page.

Two-way, extremely fast UI preview:

In the process of OpenHarmony application/service development, DevEco Studio provides developers with a previewer function, which supports bidirectional preview, fast preview, real-time preview, dynamic preview, multi-device preview, and a component preview of UI code, which is convenient for developers to check the UI running effect at any time.

  • Two-way preview: Support linkage between code editor, UI interface, and Component Tree. For example, if you select a component in the UI interface, the corresponding component in the component tree will be selected, and the corresponding code block in the editor will be highlighted; if you click on the code or component tree, it will also be highlighted in the UI interface. ; In addition, if a property is modified in the property box, the corresponding property in the code will also be modified synchronously.

  • Fast preview: In the process of developing the UI code of the interface, if the properties of the component are modified, the previewer will refresh the preview result in real-time (sub-second level) to achieve the effect of the fast preview. The current version supports eTS components.

  • Real-time preview: In the process of developing UI code, if you add or delete UI components, you just need to Ctrl+S to save, and the previewer will immediately refresh the preview results.

  • Dynamic preview: In the previewer interface, you can operate the interface interaction actions of the application/service in the previewer, such as click events, jumping, sliding, etc., which is consistent with the interface interaction experience of the application/service running on the real device.

  • Multi-device preview: Supports viewing the UI layout and interaction effects of applications/services on different devices, and supports up to 4 devices at the same time. Click the button in the upper right corner of the Previewer to turn on the Multi-profile preview switch in Profile Manager, and then you can view the running effect of applications/services on multiple devices at the same time.

  • Component preview: Support eTS component preview by adding the annotation @Preview in front of the component. In a single source file, you can use up to 10 @Preview to decorate custom components.

Brand new compilation tool Hvigor

For OpenHarmony-oriented JS/eTS development, based on the compiling, packaging, and package management technologies in the JS field, DevEco Studio provides Hvigor, an automated construction tool, to realize one-click automated construction of OpenHarmony applications/services.

Hvigor is a new front-end lightweight construction tool based on TS. Combined with the npm package management mechanism, it mainly provides key capabilities such as task management mechanism, task registration and scheduling, project model management, configuration management, and new command line entry, which is more in line with openHarmony Development habits of TS/JS developers.

Support application development based on device system capability set SysCap:

SysCap, the full name of System Capability, that is, system capability, refers to each relatively independent feature in the operating system, such as Bluetooth, WIFI, NFC, camera, etc., is one of system capabilities. DevEco Studio supports importing the system capability Syscap set defined by the device through PCID (Product Compatibility ID). After importing PCID, the editor automatically filters and automatically associates supported APIs according to the system capability SysCap set. When compiling and building the HAP package, DevEco Studio generates RPCID (Required Product Compatibility ID) according to the system capability Syscap set used by the application, and the application market automatically distributes the application to the supported devices according to the RPCID.

Supports a fully automated application signing mechanism:

In order to ensure the integrity of OpenHarmony applications and services, OpenHarmony manages applications through digital certificates and authorization files, and only signed HAPs are allowed to be installed and run on devices. In order to facilitate developers debugging, DevEco Studio provides a fully automated signature scheme to generate signature information with one click.

Rich code debugging and tuning capabilities:

  • Code debugging: DevEco Studio supports the debugging of OpenHarmony applications/services, supports one-click application packaging, installation, running, and debugging, and supports JS / TS / eTS / C++ language debugging, including support for breakpoint management, single-step debugging, and variable viewing In addition to basic debugging capabilities, it also supports variable visualization, application attach debugging, HiLog log printing, filtering, and exporting functions, which are convenient for developers to efficiently debug code and analyze and locate problems.

  • Code tuning: Supports the display of real-time CPU load and memory usage of the current application and system, supports offline analysis and display of function stack trace files and perf files, and supports recording and exporting of such files.

Known Issues

During the process of using DevEco Studio V3.0 Beta3, you may encounter the following problems, and we will improve and optimize these problems in subsequent versions.
