HarmonyOS App Publishing Guide Goes Live

Read original on 少数派
#app-publishing#developer-ecosystem#mobile-development

Learn how AI-assisted developers can move from a working prototype to publishing on HarmonyOS NEXT.

30-Second TL;DR

What Changed

The guide focuses on completing the HarmonyOS NEXT app listing and publishing workflow.

Why It Matters

The guide could lower the operational barrier for AI-assisted developers who want to ship applications on HarmonyOS NEXT. More accessible publishing procedures may encourage experimentation and increase the number of applications in the emerging ecosystem.

What To Do Next

Use the HarmonyOS App Publishing Guide to create a small AI-assisted prototype, then verify its packaging, metadata, and submission requirements before committing to a full production build.

Who should care:Developers & AI Engineers

Key Points

  • •The guide focuses on completing the HarmonyOS NEXT app listing and publishing workflow.
  • •It targets independent developers and small teams entering the emerging HarmonyOS ecosystem.
  • •AI-assisted coding has made functional code and polished UI development more accessible.
  • •Publishing readiness remains an important step beyond writing code and designing interfaces.

Deep Insight

Enhanced Key Takeaways

  • •HarmonyOS NEXT has transitioned to a 'pure' HarmonyOS architecture, removing support for Android AOSP code to enforce a native-only ecosystem.
  • •The publishing process requires mandatory security compliance testing, including automated vulnerability scanning and privacy policy verification via the Huawei Developer Alliance portal.
  • •Huawei has implemented a 'HarmonyOS Developer Service' program that provides dedicated technical support and expedited review channels for high-quality independent applications.
  • •The ecosystem now mandates the use of ArkTS and the ArkUI framework, requiring developers to migrate legacy codebases to these specific languages to pass the app store's compatibility verification.
  • •The publishing guide emphasizes the 'One-Time Development, Multi-Device Deployment' capability, which requires developers to configure specific adaptive layout parameters for different form factors like foldables, tablets, and wearables.

Technical Deep Dive

  • ArkTS: A superset of TypeScript that provides high-performance execution through the Ark Compiler, optimized for memory management in resource-constrained environments.
  • Distributed Soft Bus: A core technical component that allows apps to seamlessly share hardware capabilities (camera, screen, sensors) across devices without additional network configuration.
  • ArkUI Framework: A declarative UI development framework that uses a state-driven approach to ensure consistent rendering performance across diverse screen sizes and input methods.
  • HAP (HarmonyOS Ability Package): The standard installation package format that includes the application code, resources, and configuration files required for the HarmonyOS runtime environment.

Future ImplicationsAI analysis grounded in cited sources

HarmonyOS NEXT will achieve a 20% increase in native app penetration by Q4 2026.
The removal of AOSP support forces developers to prioritize native development, accelerating the transition of major Chinese apps to the platform.
Independent developers will shift focus toward cross-device 'Super Device' features.
The technical architecture of HarmonyOS incentivizes developers to build features that leverage distributed hardware, creating a unique value proposition compared to siloed mobile OSs.
