HarmonyOS开发实例：【app帐号管理】

应用帐号管理

介绍

本示例选择应用进行注册/登录，并设置帐号相关信息，简要说明应用帐号管理相关功能。效果图如下：

效果预览

使用说明参考鸿蒙文档：qr23.cn/AKFP8k点击或者转到。

1.首页面选择想要进入的应用，首次进入该应用需要进行注册，如已注册帐号则直接登录。

2.注册页面可设置帐号名、邮箱、个性签名、密码（带*号为必填信息），注册完成后返回登录页面使用注册的帐号进行登录。

3.登录后进入帐号详情界面，点击修改信息按钮可跳转至帐号信息修改页面重新设置帐号信息。

4.点击切换应用按钮则退出该帐号并返回首页面。重新选择想要进入的应用。

5.点击删除帐号按钮则会删除该帐号所有相关信息。

具体实现

本示例分为音乐，视频，地图三个模块
- 音乐模块
  - 使用Navigation,Button，Text,TextInput组件开发注册，登录，修改信息和切换应用页面， createAppAccountManager方法创建应用帐号管理器对象
  - 源码链接：[AccountData.ts]

鸿蒙开发岗位需要掌握那些核心要领？

目前还有很多小伙伴不知道要学习哪些鸿蒙技术？不知道重点掌握哪些？为了避免学习时频繁踩坑，最终浪费大量时间的。

自己学习时必须要有一份实用的鸿蒙（Harmony NEXT）资料非常有必要。这里我推荐，根据鸿蒙开发官网梳理与华为内部人员的分享总结出的开发文档。内容包含了：【ArkTS、ArkUI、Stage模型、多端部署、分布式应用开发、音频、视频、WebGL、OpenHarmony多媒体技术、Napi组件、OpenHarmony内核、Harmony南向开发、鸿蒙项目实战】等技术知识点。

废话就不多说了，接下来好好看下这份资料。

如果你是一名Android、Java、前端等等开发人员，想要转入鸿蒙方向发展。可以直接领取这份资料辅助你的学习。鸿蒙OpenHarmony知识←前往。下面是鸿蒙开发的学习路线图。
