HarmonyOS developers provide key technology analysis, version updates, Codelabs practice, and event information for HarmonyOS. Welcome developers to join the HarmonyOS ecosystem and create infinite possibilities together!
This article explains how to migrate HarmonyOS Web components between windows using BuilderNode, NodeController, and NodeContainer, enabling browser-like tab drag-out/in experiences without recreating pages, while emphasizing the critical rule of removing before remounting to avoid unexpected behavior.
This guide details how to use DevTools for debugging HarmonyOS frontend pages, covering wireless and USB debugging methods, setup steps, convenience scripts, and solutions for nine common issues like device detection failures and port forwarding errors.
HarmonyOS SDK introduces requestPermissionOnSetting() API to display a half-modal permission settings dialog directly in-app after user denial, replacing 5–7 step system settings navigation with a one-tap flow that takes ~8 lines of code and boosts authorization conversion and retention.
SpecArtisan addresses requirement understanding deviations in AI-assisted development by converting natural language requirements into structured, verifiable design contracts with Hoare-style pre/post conditions and branch scenarios, employing mechanical verification for structural integrity and semantic checking for behavioral correctness while producing four core artifacts.
This guide presents a five-step systematic approach to diagnose HarmonyOS ArkWeb page loading issues, covering network permissions, DevTools error analysis, callback-based error classification, User-Agent compatibility checks, and Cookie configuration for login state persistence.
This guide details ArkWeb performance optimization across four dimensions—page load, load completion delay, click response, and frame rate—using DevEco Profiler and DevTools to trace bottlenecks and apply techniques like pre-rendering, Code Cache, async JSBridge, and same-layer rendering for smooth HarmonyOS web experiences.
This article details six HarmonyOS diagnostic tools—GWPAsan for buffer overflows, AppFreeze enhanced logs for main-thread stalls, JSLeakWatcher for ArkTS memory leaks, AppFreeze-Analysis for AI-driven freeze diagnosis, APMS for proactive alerting, and DevEco Profiler for native memory leaks—explaining each tool's mechanism, core value, and target scenarios to help developers quickly resolve stability issues.
This guide explains how to enable ArkTS's built-in ArkGuard obfuscation with just two configuration files and a release build, detailing its bytecode-level operation, automatic semantic-aware rules for ArkUI and system APIs, multi-module rule management, mapping files for debugging, and step-by-step rollout with practical demos for property, filename, and dynamic access keep rules.
ArkTS introduces the `import lazy` syntax to defer module execution until first use, reducing cold-start latency by ~15% through compiler-runtime collaboration and integrated profiling tools that detect, mark, verify, and quantify redundant loads without rewriting call sites.
This guide teaches HarmonyOS developers to troubleshoot ArkTS compilation errors using log levels (ERROR/WARN/INFO/DEBUG), error code navigation via official documentation, common error patterns (syntax, imports, memory), and advanced techniques like debug-mode configuration, cache cleaning, and vendor version checks.
