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

Sample	Description
todo‑mvp	Demonstrates 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‑loaders	Fetches data using the Loaders API.
todo‑databinding	Uses the Data Binding Library.
todo‑mvp‑clean	Uses concepts from Clean Architecture.
todo‑mvp‑dagger	Uses Dagger2 to add support for dependency injection.
todo‑mvp‑contentproviders	Based on the todo-mvp-loaders sample, this version fetches data using the Loaders API, and also makes use of content providers.
todo‑mvp‑rxjava	Uses RxJava to implement concurrency, and abstract the data layer.

Samples in progress

Sample	Description
dev‑todo‑mvp‑tablet	Adds a master and detail view for tablets.
dev‑todo‑mvvm‑databinding	Based 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.

Sample	Description
todo‑mvp‑fragmentless	Uses View objects instead of Fragment objects.
todo‑mvp‑conductor	Uses 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
