Today I was Googling for "material design components" I ended up at this site:

https://material.io/components/

As I remember, I've never seen it before.

In the Android section there are instruction to use the components and ok, it seems to be the well-known Android Design Support Library:

Screenshot of dependencies

But what intrigues me is that there are components there that are not in the design library, such as:

Back Layer Layout, Material Card and Material Button.

The docs for these classes seems to be not ready yet and the links points to nowhere, like: material button doc.

There is something in the github site.

Sorry for ignorance, but what is the purpose of this site? Is it something future or something left behind?

Android 设计支持库是 Material Design 组件的前身。从支持库 28.0.0-alpha1 版本开始，设计库现在包含材料设计组件中引入的所有新组件：

我们引入了新的应用程序主题 Theme.MaterialComponents，其中包含新的属性和更新的组件样式。

我们添加了以下组件：

  • 底部应用栏
  • 芯片
  • 芯片组
  • 材质按钮
  • MaterialCardView

虽然该28.0.0-alpha1版本确实包含所有新类，但 developer.android.com 上的文档尚未包含来自设计库的更新（将文档有效地保留在以前公开可用的内容上），但如果您使用它们肯定会存在那个依赖。

支持库现在可通过 Google 的 Maven 存储库获得。我们不再支持通过 SDK 管理器下载库，并且该功能将很快被删除。

as the Support Library Setup says. And this repository and material library within it will be offical to use.

Latest dependencies to use material components is:

com.google.android.material:material:1.0.0-alpha1

Getting started with Material Components for Android will help you to setup your project.
