Year: 2026
Type: conference-paper
Abstract: With the development of mobile Internet and diversified creative expression needs, lightweight and personalized creative sharing tools have become a research hotspot. HarmonyOS supports develop-once and deploy-everywhere, providing technical support for cross-device creative applications. This paper designs and implements the "Phrase" creative expression application based on HarmonyOS. The front end adopts ArkUI and ArkTS, while the back end adopts Spring Boot 3.0+ and MySQL 8.0, together with a dual-storage architecture of local RelationalStore/Preferences and cloud MySQL. The system covers user functions such as private material acquisition, public material browsing, shared resource review, creative work editing, and meme-library management, as well as administrator functions including user management, public material management, and statistical analysis. Practical algorithms and strategies are provided for material retrieval and ranking, like/download de-duplication, incremental synchronization with conflict handling, and canvas undo/redo. Tests show that the system runs stably with good usability and compatibility, meeting end-to-end creative expression and management requirements.
