HarmonyOS 7: Window Breakpoints, On-Device AI, and Agentic Dev Tools Close the Loop

HarmonyOS 7 introduces window-breakpoint UI adaptation for triple-fold and wide-form devices, on-device Core Vision Kit APIs for 4× image super-resolution, text-to-image search, and face comparison, a lightweight ArkGraphics 3D engine, and DevEco CLI/Code agentic tooling that turns natural language into runnable apps with free GLM-5.1 on Ascend NPU.

HarmonyOS 7 Floating Tabs: Window-Width-Driven Layouts for Foldables & Tablets

This article demonstrates how to build responsive HarmonyOS 7 floating tab layouts that adapt to foldable phones, tablets, and split-screen windows by reading actual container width via ContainerReader, using breakpoints at 440/600/840 vp to switch column counts, preserving business state during layout changes, and avoiding device-type branching.

HarmonyOS 7: Spatialization & Multi-Device Adaptation — 5 Page Types to Prioritize First

This guide explains how to combine spatialization and multi-device adaptation in HarmonyOS 7, recommending that ordinary apps first refine five core page types — home/workbench, list/detail, edit/form, empty states, and settings — by restructuring information hierarchy, master-detail layouts, confirmation boundaries, and responsive width thresholds before adding visual effects.
