If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
OpenHarmony 3.2 Release 开发
HAP 包构建
商显界面开发
视频与图片播放
AtomGit 与 Git
Apache 2.0 开源合规
The real friction is usually not library usage. It is validation, time allocation, and task framing.
核心挑战不只是做出展示界面，而是交付一个兼容 OpenHarmony 3.2 Release、符合商显实际用途且稳定流畅的完整应用；评审特别看重多设备分布式、卡片、云服务等特性对行业的提升，以及容错能力，避免应用崩溃。提交流程也较重：项目申报须先审核通过，最终要在 AtomGit 提交源码、HAP 包、MD 说明和演示链接。
