The HarmonyOS Developer Community is a learning-oriented community for developers to learn, communicate, ask questions, and share.
Learn to use the free GLM-4.7 model through Alibaba's iflow-cli terminal AI assistant with step-by-step installation, VS Code and DevEco Studio plugin integration, and a complete command reference for model switching, session management, and development workflows.
This tutorial walks through creating a WeChat-like interface on HarmonyOS 6, covering four main pages — Chat, Contacts, Discovery, and Me — using Tabs for bottom navigation, Swiper for swipe gestures, and reusable ArkTS components for lists, dividers, and tab bar styling.
This article details implementing a high-performance line art extraction feature in HarmonyOS using ArkTS, covering grayscale conversion, differential edge detection, efficient pixel buffer access, sketch and comic style rendering, and time-sliced chunk processing to prevent UI freezes on large images.
This case study details how HarmonyOS 6 distributed features — soft bus, atomic services, distributed data management, and task scheduling — were used to create a unified elderly care platform connecting seniors, families, caregivers, and doctors across devices and locations, with code examples and lessons on elderly-friendly design.
This article shares the complete development journey of PromptTuner, a HarmonyOS 6 native app for prompt discovery, optimization, and management, covering architecture, ArkUI declarative UI patterns, state management, API abstraction, local analytics, privacy compliance, and performance optimization techniques with concrete code examples and metrics.
This tutorial walks through the complete lifecycle of a HarmonyOS atomic service — from UI implementation with Navigation, Grid, LazyForEach, and @Builder, to AI-powered text-to-speech, and finally manual code signing, packaging, and release via AppGallery Connect.
A HarmonyOS developer shares the full technical practice of building a children's flag-learning app, covering technology selection (Core Speech Kit, ArkTS, Stage model), core feature implementation (offline voice synthesis/recognition, canvas drawing, puzzle game), global state management with AppStorage, performance optimizations for 200+ flags, and future plans for multi-device collaboration and AI integration.
Learn to implement scroll-responsive navigation bars in HarmonyOS 6.0 using HdsNavigation's dynamicHideTitleBar API, with step-by-step configuration, hide modes (SCROLL_UP_TO), offset tuning, blur effect combination, conditional enabling, and debugging techniques for smooth immersive UIs.
A developer shares technical insights from building 'Light Meal,' a cross-device health diet app on HarmonyOS 6, covering declarative UI with ArkUI, @ComponentV2 state management, performance optimizations cutting startup time 40%, service cards boosting daily active users 20%, and fine-grained permissions raising consent rates to 85%.
The article shares the development of 'Hongtu Zhidao', a travel app built on HarmonyOS 6, detailing its architecture, challenges like multi-tab navigation and AI content persistence, and solutions using ArkTS/ArkUI declarative UI, ArkData local storage, AppStorageV2 for global state, real-time AI itinerary planning, and DevEco Studio's hot reload and multi-device preview.
