Deveco Studio

On September 29th, Huawei has launched DevEco Studio 3.0 and released the DevEco Studio 3.0 beta 1, which is now available to download for the HarmonyOS development. This new version brings two new tool support and existing feature optimizations for the next version of the HarmonyOS operating system.

Huawei DevEco Studio is a one-stop integrated development environment (IDE) powered by the IntelliJ IDEA Community Edition and oriented to HarmonyOS-based devices in all scenarios. It allows you to create project templates, and develop, build, debug, and release HarmonyOS apps from end to end, thereby empowering you to innovate and develop products.

The developers with the eligible resource can download this version from the official website of the company. Users of 64-bit Windows 10 and macOS 10.14/10.15/11.2.2 with a minimum of 8GB RAM, 100GB internal storage, and 1280×800 pixel resolution can download this version.

Huawei DevEco Studio 3.0 beta 1

Let’s explore the new changes that Huawei DevEco Studio 3.0, beta 1 brings-


New Features:

  1. New Scoring Tool: The new Scoring Tool local HarmonyOS application or atomic service evaluation tool tests and evaluates the quality of HarmonyOS applications or atomic services. The developer uses it to perform self-testing on HarmonyOS applications or atomic services. In addition, it can quickly provide evaluation results and improvements Suggestions to help developers quickly improve product quality.
  2. Support for compiling a single Module: When compiling and constructing the HAP package, new support for compiling a single Module is added. For scenarios where only one of the Modules needs to be compiled in a multi-module project, the compilation and construction will have more improve speed. At the same time, it supports a one-click reconstruction of the HAP package. Now before compiling and building HAP, the Clean Project operation will automatically execute.

Enhanced Features:

  1. Optimization: Compile and build the plug-in update to version
  2. Simulator mirroring update: The remote simulator mirroring update supports API 6 Release. At the same time, the distributed simulator adds support for the “Phone+TV” networking scenario.
  3. Low-code Development Function: Now supports tablet device development, atomic layout development, and multi-device development switching functions.
  4. Enhanced Editors: Java, XML, and JSON editors have enhanced, resource index errors support quick fixes, and support quick viewing of resource values.
  5. Ohos View Support: The project view supports the Ohos view. The default view is the Project view, and the developer can switch it manually.

Now, let’s move further and check what are the know issues-

After the beta 1 installation, there may be some problems in the future. You can check below for the details and pay more attention to it. However, the company will improve and optimize them with the upcoming releases.

  1. When using the C++ variable visualization function to debug, the single-step debugging operation will be stuck. Meanwhile, the continuous change value of the variable will be abnormal.
  2. Don’t support the preview for projects of Video Player Ability(Java), Device Control Ability(JS), Image Editor Ability(Java), Picture Browser Ability(Java).
  3. The project created by the DeviceConfigureAbility(JS) template does not support Js debugging.
  4. Splash Screen Ability (JS) template does not support the writing of app. terminate, and there will be debugging problems.
  5. If there are multiple modules in the project and the “package” is the same, multiple hap installation and debugging are not supported, you can select a single hap package for debugging.
  6. The About Ability(JS) template does not support this writing, and there will be debugging problems.

Huawei will continuously solve survival problems: Chairman




On September 26, Huawei attended the opening ceremony of STW 2022. At this event, the new rotating chairman of the company – Xu Zhijun delivered a short speech. He described how Huawei needs to make efforts in the field of research and development to solve environmental and survival problems.

Xu Zhijun reports that for confronting the survival problems in an extreme environment and developing a fruitful future, Huawei must continue its research and open innovation. Although, the company is trying its level best to prepare itself for future challenges. Yet, it is necessary to concentrate well on the technical field.

Over the last decade, Huawei has funded more than 845 billion yuan [118 trillion USD] in research and development. Besides, it marked an expenditure of more than 20 billion yuan [2.81 billion USD] in basic research.

However, the Chinese manufacturer managed to establish 86 basic tech labs and 172 joint laboratories for innovation. But, it’s time to focus on the new emerging obstacles that could harm the growth and evolution of the company, if not prevented.


Some major challenges:

Xu believes that even after a lot of achievements, several hurdles are waiting ahead in this evolution journey:

  • Firstly the carbon neutrality goal. Challenges like poor stability in energy generation, low conversion efficiency, high energy storage price, less security, and mismanagement are standing in the mid-way.
  • Global computing power demand is facing 2-3 orders of magnitude in the next coming years. Supply Chain and other essential components require more enhancement.
  • Users are expecting the 5.5G network to exhibit an increase of 5 times in the uplink and downlink rates. What kind of core technology will the 6G network need is still a big question for the company.
  • Artificial Intelligence is still a topic of concern for many operators. Its security, interpretability, small samples, computing data, and more are not easy to handle.

And the list continues to a far distance. Though the company has come up with several things, there is still a lot to move on with. Xu says,

“We need to work together to fully release the productivity of all walks of life, give birth to new industries, new business forms, and new models, and promote the progress of the world.”

Huawei and other companies certified for 100W fast charging power



Huawei 100W fast charging power

Today, Huawei and some other tech manufacturers have gained fast charging certificates with a certified power of 100W. Apart from the smartphone devices, the certificates have approached some other charging equipment as well.

So far, we only heard that the general charging power of the new technology at the moment is 40W and it will gradually come to the count of 65W. However, the fast-charging certified power for Huawei and other partners is dynamically 100W.

Aside from smartphones, a few fast-charging chips, and charging products have also obtained these certificates. This is a good sign and indicates that soon consumers will experience an advanced way of powering up their devices.

Fast Charging: New Addition to the Technology field

Fast Charging is a new topic in the world of technology. Recently, the China Communications Standard Association and Telecom Terminal Industry jointly conducted a huge fast charging achievement conference in Beijing.


At this event, the cooperation released the first batch of fast charging certificates for 11 high-end products. These products consist of 4 terminals, 5 adapters, and 2 chipsets from 6 companies including Huawei, Oppo, Vivo, and Xiaomi.

As a major part of this event, all four tech giants also delivered a short speech on how this unified fast charging will bring a safer and more secure environment for consumers. Thereafter, the cooperations began the certificate distribution procedure.

New Charging Technology will take time to adapt!

The Chairman of the Telecommunications Terminal Industry Association – Shi Xiaoguang mentioned that the sudden change in the traditional charging technology can give rise to several problems. For instance interoperability issues in interfaces, protocols, cables, and more.

Consequently, these issues will not only harm the user experience but will also risk security. Hence, to maintain the charging ecosystem, the Telecom Association will continue to integrate with China Communications firm to promote and expand the fast charging technology in the field of technical application.


In this manner, the objective of bringing an efficient and universal charging technology to users will be fulfilled.
