History

DevEco Studio was launched on September 9, 2020, a day before Huawei Developer Conference 2020 (HDC 2020) as the first stable build starting from version 1.0 for Huawei Vision TVs on HarmonyOS 1 and HarmonyOS 2 Beta versions for phones, tablets and watches in app development via Ark Compiler. [3]

DevEco Studio 2.1 was released on June 4, 2021 with cross-device project templates, atomic service development and other features with HarmonyOS 2.0 SDK for HarmonyOS 2 that was launched on June 2, 2021. On July 2021, Huawei launched sdkmgr, a new HarmonyOS SDK management tool. [4] [5]

On July 8, 2022, after the following release of DevEco Studio 3.0 Beta 4 JS/eTS declarative programming development with ArkUI replaced imparative Java development as Huawei's preferred language for HarmonyOS app development since HarmonyOS .hap module of .app file packaged apps don't support Java language on API8 for HarmonyOS 3.0 [6] as Huawei plans to release its own Cangjie programming language in Q4 2024 for HarmonyOS which is equivalent to Google's Kotlin for Android platforms and Apple's Swift for Apple platforms. [7] Java is still supported, as is C++ on older API level versions of the previous versions of HarmonyOS 2.0. The later 3.0 IDE update came with in-house Hvigor build tool developed by Huawei that replaced Java based Gradle on 1.0, which is a newer 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 and Oniro OS development tools for TS/JS developers that supports OpenHarmony SDK for OpenHarmony applications. Alongside faster UI preview on IDE in event driven app development. [8]

On April 8, 2023, Huawei DevEco Studio rolled out the 3.1 API 9 release version for the developers that contains HarmonyOS 3.1 SDK that debuts the refined eTS language as ArkTS, Huawei's forked TypeScript programming language for more advanced apps, with the new structure of the HarmonyOS App package file format after built and packaged in a stage model. DevEco studio 3.1 was under beta for the past 6 months prior. DevEco Studio 3.1.1 was launched outside China to global markets in January 2024. [9] AOT (Ahead Of Time) compilation on ArkCompiler Toolchain was introduced into DevEco Studio 3.1.1 with HarmonyOS 3.1 SDK and OpenHarmony 3.2 that allows the ability to compile bytecode into machine code that can be run on the target side (i.e., the device running the application) on the host side (i.e., the computer running DevEco Studio) in advance, so that the bytecode can be fully compiled and optimized, and it can be accelerated when it is put on the target side. [10]

Since August 4, 2023, DevEco Studio went through internal changes with HarmonyOS NEXT development based on OpenHarmony, with toolkits, compilers, new structural base for app development taking advantage of the full developer kit with HarmonyOS SDK like OpenHarmony SDK, that contains Enablement Kit. Alongside DevEco Studio Testing. By October 2023, Huawei internally updated it's DevEco Studio 3.2 retooled for HarmonyOS NEXT 3.1 SDK API 9 and 10 to 4.0 Canary builds SDK on internal DevEco Studio 4.1.3 IDE on API 12 for macOS Internal and registered external third-party selected partnered developers in China. January 18 2024, Huawei announced HarmonyOS NEXT ecology plan for Q2 Beta and Q4 commercialisation with internal shipment of upgraded DevEco Studio. By April 11, 2024, Huawei formally announced a new HarmonyOS NEXT Beta with a new DevEco Studio IDE 5.0 upgrade by June 2024, that was internally upgraded for external developers by April 2, 2024 through rigorous feedback from domestic Chinese developer community and maturity of developer tools. [11]

Previously, the models that could run were and above, that was only be used with emulators and the capabilities were limited. Those toolkits were upgraded to the development preview for devices such as Mate 40 Kirin 990, P50 Snapdragon, Mate 60, Mate 60 Pro and Mate X5 Kirin 9000s powered devices. It is reported that the previous IDE used on version 3.2 of DevEco Studio, use of ArkTS syntax is more matured and 5.0 version of the editor is syntactically rigorous and provides more complete and rich capabilities from API 9 to API 12 upgrade. [12]

You'll get access to key insights when developing and releasing premium products. It includes the DevEco Marketplace. [13]

DevEco Marketplace

The DevEco Marketplace which was launched on September 25, 2021 that allows developers access to various development resources here including native libraries, third-party libraries, sample codes, and more., which can make app development of Super Device hardware and atomic services easier to implement into native based HarmonyOS apps.

HarmonyOS DevEco Marketplace polymerization a wealth of ecosystem resources development kits, enabling developers to easily obtain the resources needed one-stop, easy to complete the development of Hong Meng-chi of hardware, atomic services, and applications.

The DevEco Marketplace website divides resources into two categories, which are displayed on the following two pages: “Device Components” page: Resource library for device developers, providing release and component package resources.

The marketplace includes System Bundles such as a wide array of system capabilities such as kernel, drivers, and service framework bundles. Atomic Services section that includes in typical scenarios which includes security, multimedia, and network atomic services. Project Templates section that includes Application development project templates for Super Device and various devices, covering various typical industry use cases and Code Samples of API code samples and typical scenarios for HarmonyOS apps. [14]
