对于低版本的鸿蒙系统

1 使用hdc的命令查询手机使用的 sdk 版本

2 DevEco中下载对应的SDK

3 关闭当前的工程

4 使用对应的SDK 新建一个新的工程

5 重新申请一个 keysotre 就可以运行了

在HarmonyOS鸿蒙Next stage Model下开发，目前确实不支持在鸿蒙3.0系统的真机上进行调试。Next stage Model是鸿蒙系统的一个新架构，它引入了新的开发框架和API，与鸿蒙3.0系统的架构存在差异。由于Next stage Model的设计目标和功能特性与鸿蒙3.0不完全兼容，因此在进行开发时，无法直接在鸿蒙3.0系统的真机上进行调试。开发者需要使用支持Next stage Model的设备或模拟器进行调试和测试。
