HarmonyOS is gaining traction across multiple device form factors, but developers face the challenge of maintaining separate codebases for phones, tablets, and TVs. This article provides a practical approach to building a single app that adapts seamlessly. Key strategies include using HarmonyOS's adaptive layout capabilities, leveraging the distributed device framework for cross-device interactions, and handling input differences (touch vs. remote control). The article also discusses performance considerations and testing across screen sizes. For developers entering the HarmonyOS ecosystem, this is a valuable resource to reduce development and maintenance costs while reaching a wider audience. The approach mirrors concepts from responsive web design but is tailored to HarmonyOS's native APIs and device capabilities.
This article explores how to architect a single HarmonyOS application that adapts to phones, tablets, and TVs. It highlights the importance of responsive layouts, device-specific capabilities, and the HarmonyOS distributed framework. For developers targeting the growing HarmonyOS market, this is a practical reference for reducing fragmentation.
