一、ArkUI框架

ArkUI框架是鸿蒙开发中使用的一套UI框架，类似于Android或iOS中的UI一样，具备了界面布局、动画、UI交互等基本功能。方舟开发框架采用了基于ArkTS语言的声明式开发范式。UI的更新方式采用数据驱动。

二、应用模型

应用模型，就是应用程序运行所必须具备的能力和运行机制。

Stage模型是 HarmonyOS API 9开始新增的应用模型，是官方主推并且会长期支持的应用模型。

三、项目的目录结构

1.app.json5配置文件

{
  "app": {
    "bundleName": "com.example.myapplication",
    "vendor": "example",
    "versionCode": 1000000,
    "versionName": "1.0.0",
    "icon": "$media:app_icon",
    "label": "$string:app_name"
  }
}

2.module.json5配置文件

{
  "module": {
    "name": "entry",
    "type": "entry",
    "description": "$string:module_desc",
    "mainElement": "EntryAbility",
    "deviceTypes": [
      "phone"
    ],
    "deliveryWithInstall": true,
    "installationFree": false,
    "pages": "$profile:main_pages",
    "abilities": [
      {
        "name": "EntryAbility",
        "srcEntry": "./ets/entryability/EntryAbility.ets",
        "description": "$string:ability_desc",
        "icon": "$media:icon",

        "exported": true,
        "skills": [
          {
            "entities": [
              "entity.system.home"
            ],
            "actions": [
              "action.system.home"
            ]
          }
        ]
      }
    ]
  }
}

3.模块级build-profile.json5配置文件

{
  "apiType": "stageMode",
  "buildOption": {
  },
  "buildOptionSet": [
    {
      "name": "release",
      "arkOptions": {
        "obfuscation": {
          "ruleOptions": {
            "enable": true,
            "files": [
              "./obfuscation-rules.txt"
            ]
          }
        }
      }
    },
  ],
  "targets": [
    {
      "name": "default"
    },
    {
      "name": "ohosTest",
    }
  ]
}

4.模块级构建脚本hvigorfile.ts文件

import { hapTasks } from '@ohos/hvigor-ohos-plugin';
export default {
    system: hapTasks,  /* Built-in plugin of Hvigor. It cannot be modified. */
    plugins:[]         /* Custom plugin to extend the functionality of Hvigor. */
}

5.obfuscation-rules.txt混淆规则文件

# Define project specific obfuscation rules here.
# You can include the obfuscation configuration files in the current module's build-profile.json5.
#
# For more details, see
#   https://gitee.com/openharmony/arkcompiler_ets_frontend/blob/master/arkguard/README.md
# Obfuscation options:
# -disable-obfuscation: disable all obfuscations
# -enable-property-obfuscation: obfuscate the property names
# -enable-toplevel-obfuscation: obfuscate the names in the global scope
# -compact: remove unnecessary blank spaces and all line feeds
# -remove-log: remove all console.* statements
# -print-namecache: print the name cache that contains the mapping from the old names to new names
# -apply-namecache: reuse the given cache file
# Keep options:
# -keep-property-name: specifies property names that you want to keep
# -keep-global-name: specifies names that you want to keep in the global scope

6.应用级配置信息build-profile.json5文件
