## 简介<a name="section1470103520301"></a>

为帮助开发者快速熟悉OpenHarmony SDK所提供的API和应用开发流程，我们提供了一系列的应用示例，即Sample。每一个应用示例都是一个独立的DevEco Studio工程项目，开发者可以将工程导入到DevEco Studio开发工具，通过浏览代码、编译工程、安装和运行应用示例来了解应用示例中涉及API的使用方法。

## 约束<a name="section18841871178"></a>

安装应用示例之前，请先查看"README_zh.md"文件来确认应用示例是否为stage模型，若为Stage模型需要查看entry/src/main路径下的module.json5文件中的"deviceType"字段来确认该应用支持的设备类型；否则为FA模型，查看entry/src/main路径下的config.json文件中的"deviceType"字段来确认该应用示例支持的设备类型，两种模型都可尝试通过修改该字段使其可以在相应类型的设备上运行。

## 使用方法<a name="section17988202503116"></a>

1. 将独立的应用示例工程导入DevEco Studio进行编译构建及运行调试。
2. 部分应用示例中含有多个模块，开发者可以选择对单个模块进行编译构建，生成一个HAP应用安装包，也可以对整个工程进行编译构建，生成多个HAP应用安装包。
3. 安装运行后，即可在设备上查看应用示例运行效果，以及进行相关调试。
