+# MDM应用配置说明
+
+## 概述
+
+此应用是一个OpenHarmony MDM（移动设备管理）应用，用于控制设备相机功能。为了使MDM功能正常工作，需要进行特殊的签名配置。
+
+## 配置步骤
+
+### 1. 注册成为企业开发者
+
+1. 访问[华为开发者联盟](https://developer.huawei.com/)官网
+2. 注册并认证为企业开发者
+
+### 2. 创建项目和应用
+
+1. 登录AppGallery Connect
+2. 创建新项目
+3. 在项目中创建应用
+4. 记录应用的包名（Bundle Name）
+
+### 3. 申请MDM证书和Profile
+
+1. 在AppGallery Connect中进入"用户与访问"->"设备管理"->"证书与Profile"
+2. 申请MDM证书
+3. 创建Profile文件，并添加以下权限：
+   - `ohos.permission.ENTERPRISE_MANAGE_RESTRICTIONS`
+   - `ohos.permission.MANAGE_ENTERPRISE_DEVICE_ADMIN`
+   - `ohos.permission.ENTERPRISE_GET_DEVICE_INFO`
+
+### 4. 配置开发环境签名
+
+在DevEco Studio中配置签名：
+
+1. 打开项目后，选择菜单 "File" -> "Project Structure"
+2. 在左侧面板选择 "Project"
+3. 在右侧面板中找到 "Signing Configs"
+4. 选择 "Automatically generate signature" 选项
+5. 点击 "Apply" 保存配置
+
+### 5. 修改应用包名
+
+MDM应用需要使用特定的包名格式，通常以企业域名开头。修改[module.json5](file:///Users/yuangyaa/workfiles/huawei/easyMDM/entry/src/main/module.json5)中的`bundleName`字段：
+
+```json
+{
+  "app": {
+    "bundleName": "com.yourcompany.mdmapp",
+    // ... 其他配置
+  }
+}
+```
+
+## 重要注意事项
+
+1. MDM应用只能安装在企业设备上，不能在普通消费者设备上运行
+2. MDM功能需要设备管理权限激活后才能使用
+3. 签名配置是必需的，否则MDM功能将无法正常工作
+4. 应用需要通过hdc命令激活设备管理权限进行测试
+
+## 测试说明
+
+在开发环境中测试MDM功能需要：
+
+1. 使用hdc命令激活设备管理权限：
+   ```
+   hdc shell bm enable-admin -n com.yourcompany.mdmapp/.EnterpriseAdminAbility
+   ```
+
+2. 使用hdc命令解除激活：
+   ```
+   hdc shell bm disable-admin -n com.yourcompany.mdmapp/.EnterpriseAdminAbility
+   ```
+
+## 常见问题
+
+### 1. 编译时出现权限错误
+
+确保在[module.json5](file:///Users/yuangyaa/workfiles/huawei/easyMDM/entry/src/main/module.json5)中声明了所有必需的MDM权限，并且这些权限已在Profile中配置。
+
+### 2. 运行时无法控制设备功能
+
+确保应用已被正确激活为设备管理器，并且设备支持MDM功能。
