Android 官方示例：android-architecture 学习笔记(一)

项目地址：https://github.com/googlesamples/android-architecture

architecture的解释：n. 建筑学；建筑风格；建筑式样；建筑艺术；架构。 说明该项目就是GG官方的一个关于架构的示例

项目down下来之后，使用git 查看分支就是一个个简单的架构示例 如下：

master todo-databinding * todo-mvp todo-mvp-clean todo-mvp-contentproviders todo-mvp-dagger todo-mvp-loaders todo-mvp-rxjava remotes/origin/HEAD -> origin/master remotes/origin/dev-todo-mvp-clean-fix-memory-leak remotes/origin/dev-todo-mvp-tablet remotes/origin/dev-todo-mvp-tablet_dialogfragment remotes/origin/dev-todo-mvvm-databinding remotes/origin/master remotes/origin/todo-databinding remotes/origin/todo-mvp remotes/origin/todo-mvp-clean remotes/origin/todo-mvp-contentproviders remotes/origin/todo-mvp-dagger remotes/origin/todo-mvp-loaders remotes/origin/todo-mvp-rxjava

README.md中的描述：

Stable samples

SampleDescriptiontodo‑mvpDemonstrates a basic Model‑View‑Presenter (MVP) architecture and provides a foundation on which the other samples are built. This sample also acts as a reference point for comparing and contrasting the other samples in this project.todo‑mvp‑loadersFetches data using the Loaders API.todo‑databindingUses the Data Binding Library.todo‑mvp‑cleanUses concepts from Clean Architecture.todo‑mvp‑daggerUses Dagger2 to add support for dependency injection.todo‑mvp‑contentprovidersBased on the todo-mvp-loaders sample, this version fetches data using the Loaders API, and also makes use of content providers.todo‑mvp‑rxjavaUses RxJava to implement concurrency, and abstract the data layer.

Samples in progress

SampleDescriptiondev‑todo‑mvp‑tabletAdds a master and detail view for tablets.dev‑todo‑mvvm‑databindingBased on the todo-databinding sample, this version incorporates the Model‑View‑ViewModel architecture.

For information about planned samples, see “New sample” issues.

External samples

External samples are variants that may not be in sync with the rest of the branches in this repository.

SampleDescriptiontodo‑mvp‑fragmentlessUses View objects instead of Fragment objects.todo‑mvp‑conductorUses the Conductor framework to refactor the app to use a single Activity architecture.

简单的说下，”stable samples” 就是稳定的示例；”smaples in progress”就是正在完善开发中的示例；”external samples”就是其他一些开发者fork本项目后做的一些改进版

关于todo app这个项目的内容，它的基本业务：核心就是一个任务列表。包括编辑创建任务(任务属性有标题和内容)；勾选已完成的任务；查看所有任务列表，有三种状态，All、Active、Completed；任务统计 不同分支，只是用了不同的architecture
