With the growing importance of smartphones, developers face the challenge of creating separate applications for multiple platforms (e.g., Android, iOS, and HarmonyOS), leading to increased development costs and longer iteration cycles. One potential solution is to develop an app on one platform and then automatically convert it to other platforms, reducing the need for separate development efforts. However, migrating user interfaces (UIs) between platforms is particularly challenging due to significant differences in layout structures and development paradigms, such as the disparity between XML layout files in Android and ArkUI framework in HarmonyOS. Manual conversion of UIs is time-consuming, error-prone, and inefficient, necessitating an automated solution to streamline the process and enable seamless migration from Android to HarmonyOS. To address this challenge, we propose the A2H Converter, an automated tool for migrating Android UIs to HarmonyOS. The tool employs an large language model (LLM)-driven multi-agent framework to convert Android XML layouts into HarmonyOS ArkUI layouts. Using the RAG combing with decision rules, the system maps Android UI components to ArkUI equivalents, while a reflective mechanism continuously improves conversion accuracy. A2H Converter handles project-level layouts, ensuring consistency across multiple files and addressing complex UI logic. Experiments on six Android applications collected from GitHub demonstrate that our A2H Converter achieves a migration success rate of over 90.1%, 89.3%, and 89.2% at the component, page, and project levels, respectively.
