我们就本项目 "被卖课" 一事，在掘金发表一期专访 [《开源项目被人拿去做课程卖了 1000 多万是什么体验》](https://juejin.im/post/5ecb4950518825431a669897)
本项目系我为方便开发者们 **无痛理解 Google 开源 Jetpack MVVM 中每个架构组件的 存在缘由、职责边界**，而 **精心设计的高频应用场景**，
与此同时，本项目是作为 [《重学安卓》](https://xiaozhuanlan.com/topic/6017825943)专栏 Jetpack MVVM 系列文章 “配套项目” 而存在，**文章内容和项目代码设计均涉及本人对 Jetpack MVVM 独家理解，本人对此享有著作权**。
任何组织或个人，未经与作者本人沟通，不得将本项目代码设计和本人对 Jetpack MVVM 独家理解用于 "**打包贩卖、引流、出书 和 卖课**" 等商业用途。
# 架构图一览
# 前言
上周我在各大 “技术社区” 发表了一篇 [《Jetpack MVVM 精讲》](https://juejin.im/post/5dafc49b6fb9a04e17209922)，原以为在 “知识网红” 唱衰 Android 的 2019 会无人问津，没想到文章一经发布，从 “国内知名公司” 架构师、技术经理，到 “世界级公司” Android 开发都在看。
且从读者反馈来看，近期大部分 Android 开发已跳出舒适圈，开始尝试认识和应用 Jetpack MVVM 到实际项目中。
只可惜，关于 Jetpack MVVM，网上多是 **东拼西凑、人云亦云、通篇贴代码** 文章，这不仅不能提供 “完整视角” 帮助读者 首先明确背景状况，更是给还没入门 Jetpack 读者 **徒添困扰**、起 **劝退** 作用。
好消息是，这一期，我们带着 **精心打磨 Jetpack MVVM 最佳实践案例** 来了！

# 项目简介
本人拥有 3 年 “移动端业务架构” 践行和设计经验，领导或参与团队 “重构” 中大型项目多达十数个，对 Jetpack MVVM 架构在 “确立规范化、标准化开发模式 以 **减少不可预期错误**” 所作的努力，有深入理解。
在这个案例中，我将为你展示，Jetpack MVVM 是如何 **以简驭繁** 地将原本十分容易出错、一出错就会耽搁半天的开发工作，通过寥寥几行代码 轻而易举完成。
> 👆👆👆 划重点！
该项目中，
> 我们为 **横、竖屏** 场景安排两套 **截然不同布局**，且在 [生命周期](https://xiaozhuanlan.com/topic/0213584967)、[重建机制](https://xiaozhuanlan.com/topic/7692814530)、[状态管理](https://xiaozhuanlan.com/topic/7692814530)、[DataBinding](https://xiaozhuanlan.com/topic/9816742350)、[ViewModel](https://xiaozhuanlan.com/topic/6257931840)、[LiveData](https://xiaozhuanlan.com/topic/0168753249) 、[Navigation](https://xiaozhuanlan.com/topic/5860149732) 等知识点帮助下，通过寥寥几行代码，轻松做到 **在横竖屏两种布局间 无缝切换，且不产生任何 预期外错误**。
> 我们在多个 Fragment 页面 分别安排 **播放状态指示器**（包括 播放暂停按钮状态、播放列表当前索引指示 等），并向你展示 “如何” 及 “为何” 通过 [LiveData](https://xiaozhuanlan.com/topic/0168753249) **配合** 可信源 [ViewModel](https://xiaozhuanlan.com/topic/6257931840) 或单例，实现 **全应用范围内 “可追溯事件” 统一分发**。
> 我们在 Fragment 和 Activity 之间分别安排 跨页面通信，从而向你展示 如何基于 **迪米特原则**（也称 最少知道原则）、通过 UnPeekLiveData 和 应用级 SharedViewModel 实现 **生命周期安全、确保消息同步可靠一致的 页面通信**。
> 我们在 `ui.page` 、`domain.request` 、`data.repository` 等目录下，分别安排 视图控制器、[ViewModel](https://xiaozhuanlan.com/topic/6257931840) 、Dispatcher 、DataRepository 等 内容，从而向你展示，**单向依赖** 架构设计，是如何通过分层 数据请求和响应，**规避 “内存泄漏”** 等问题。
> 本项目代码一律采用 经过 ISO 认证 标准化工业级语言 Java 来编写。且在上述类中，我们大都 **提供丰富注释**，助你理解 “骨架代码” 为何要如此设计、如此设计能 **在软件工程背景下** 避免哪些不可预期错误。
除了 **在 "以简驭繁" 代码中 掌握 MVVM 最佳实践**，你还可从该项目中获得内容包括：
1. 整洁代码风格 和 标准资源命名规范。
2. 对 “视图控制器” 知识点的 深入理解 和 正确使用。
3. AndroidX 和 Material Design 2 全面使用。
4. ConstraintLayout 约束布局最佳实践。
5. **优秀的 用户体验 和 交互设计**。
6. 绝不使用 Dagger，绝不使用奇技淫巧、编写艰深晦涩代码。
7. The one more thing is：
即日起，可在 "应用商店" 下载体验！

# Who is using
根据小伙伴们 “开源库使用情况” 匿名调查问卷参与，截至 2022年5月28日，我们了解到
包括 “腾讯音乐、网易、BMW、TCL” 在内诸多知名厂商软件，都参考过我们开源的此架构模式，或正在使用我们维护的 [UnPeek-LiveData](https://github.com/KunMinX/UnPeek-LiveData) 等框架。
目前已将统计数据更新到 相关开源库 ReadMe 中，错过本次问卷调查的小伙伴也不用担心，我们继续对此保持开放，不定期将小伙伴们登记的公司和产品更新到表格，
以便吸纳更多小伙伴参与对 “架构组件” 的使用和反馈，集众人所长，让组件得以不断演化和升级。

<p><span>并且从读者的反馈来看，近期大部分安卓开发 已跳出舒适圈，开始尝试认识和应用 Jetpack MVVM 到实际的项目开发中。</span></p>
<p><span>只可惜，关于 Jetpack MVVM，网上多是 </span><strong><span>东拼西凑、人云亦云、通篇贴代码</span></strong><span> 的文章，这不仅不能提供完整的视角 来帮助读者 首先明确背景状况，更是给还没入门 Jetpack 的读者 </span><strong><span>徒添困扰</span></strong><span>、起到 </span><strong><span>劝退</span></strong><span> 的作用。</span>

<h2><a class="md-header-anchor" name="项目简介"></a><span>项目简介</span></h2>
<p><span>本人拥有 3 年的 移动端架构 践行和设计经验，领导或参与团队重构的 中大型项目 多达十数个，对 Jetpack MVVM 架构在 确立规范化、标准化 开发模式 以 </span><strong><span>减少不可预期的错误</span></strong><span> 所作的努力，有着深入的理解。</span>
</p>
<p><span>在这个案例中，我将为你展示，Jetpack MVVM 是如何 </span><strong><span>以简驭繁</span></strong><span> 地 将原本十分容易出错、一出错就会耽搁半天时间的开发工作，通过 寥寥的几行代码 轻而易举地完成。</span>
</p>
<blockquote><p><span>👆👆👆 划重点！</span></p></blockquote>
<p> </p>
<p><span>在这个项目中，</span></p>
<blockquote><p>
<span>我们为 </span><strong><span>横、竖屏</span></strong><span> 的情况 分别安排了两套 </span><strong><span>截然不同的布局</span></strong><span>，并且在 </span><a
href='https://xiaozhuanlan.com/topic/0213584967'><span>生命周期</span></a><span>、</span><a
href='https://xiaozhuanlan.com/topic/7692814530'><span>重建机制</span></a><span>、</span><a
href='https://xiaozhuanlan.com/topic/7692814530'><span>状态管理</span></a><span>、</span><a
href='https://xiaozhuanlan.com/topic/9816742350'><span>DataBinding</span></a><span>、</span><a
href='https://xiaozhuanlan.com/topic/6257931840'><span>ViewModel</span></a><span>、</span><a
href='https://xiaozhuanlan.com/topic/0168753249'><span>LiveData</span></a><span> 、</span><a
href='https://xiaozhuanlan.com/topic/5860149732'><span>Navigation</span></a><span> 等知识点的帮助下，通过寥寥几行代码，轻松做到 </span><strong><span>在横竖屏两种布局间 无缝地切换，并且不产生任何 预期外的错误</span></strong><span>。</span>
</p></blockquote>
<p> </p>
<blockquote><p><span>我们在多个 Fragment 页面 分别安排了 </span><strong><span>播放状态 指示器</span></strong><span>（包括 播放暂停按钮状态、播放列表当前索引指示 等），并向你展示了 如何 以及为何 通过 </span><a
href='https://xiaozhuanlan.com/topic/0168753249'><span>LiveData</span></a><span> </span><strong><span>配合</span></strong><span> 作为可信源 的 </span><a
href='https://xiaozhuanlan.com/topic/6257931840'><span>ViewModel</span></a><span> 或单例，来实现 </span><strong><span>全应用范围内 可追溯事件 的统一分发</span></strong><span>。</span>
</p></blockquote>
<p> </p>
<blockquote><p><span>我们在 Fragment 和 Activity 之间分别安排了 跨页面通信，从而向你展示 如何基于 </span><strong><span>迪米特原则</span></strong><span>（也称 最少知道原则）、通过 UnPeekLiveData 和 应用级 SharedViewModel 来实现 </span><strong><span>生命周期安全的、确保消息同步一致性和可靠性的 页面通信</span></strong><span>（事件回调）。</span>
</p></blockquote>
<p> </p>
<blockquote><p>
<span>我们在 </span><code>ui.page</code><span> 、</span><code>data.repository</code><span>、</span><code>bridge.request</code><span> 等目录下，分别安排了 视图控制器、</span><a
href='https://xiaozhuanlan.com/topic/6257931840'><span>ViewModel</span></a><span> 、DataRepository 等 内容，从而向你展示，</span><strong><span>单向依赖</span></strong><span> 的架构设计，是如何通过分层的 数据请求和响应，来 </span><strong><span>规避 内存泄漏</span></strong><span> 等问题。</span>
</p></blockquote>
<p> </p>
<blockquote><p>
<span>本项目的代码一律采用 经过 ISO 认证的 标准化工业级语言 Java 来编写。并且，在上述目录 所包含的 类中，我们大都 </span><strong><span>提供了丰富的注释</span></strong><span>，来帮助你理解 骨架代码 为何要如此设计、如此设计能够 </span><strong><span>在软件工程的背景下</span></strong><span> 避免哪些不可预期的错误。</span>
</p></blockquote>
<p>
</p>
