1项目介绍和基础架构
在现代生活中，越来越多的都市居民也开始崇尚居家做菜的理念。为了更好的服务这部分的群体，因此我们决定制作简洁方便的食谱应用为快节奏的都市工作者提供方便快捷的食谱汇总，能够更轻松的完成自己想要的菜品。并通过获取网络上的食谱资源来满足用户对选择范围的需求。用户可以通过应用来获取自己想要的食谱并进行收藏。
项目采用了 MVP 的架构。presenter 通过 view 和 model 接口的引用，来调用具体实现类实现的方法，这么做的好处是，业务结构清晰，且将来更换实现类更为方便。

2使用的开发框架和资源库

2.1Material Design：

由 Google 开发的设计语言，充满简练干净的风格。食谱的布局里使用了许多来自 Material Design 的控件。确定了食谱软件简洁的 ui 风格。

2.2litePal：

LitePal 是一款开源的 Android 数据库框架，采用对象关系映射（ORM）模式， 将常用的数据库功能进行封装。软件中，用户的账号信息都由 LItePal 来进行本地存储。

2.3Retrofit2：

Retrofit2 针对于 Android/Java 的、基于 okHttp 的、一种轻量级且安全的、并使用注解方式的网络请求框架。
Retrofit 使用注解方式，大大简化了我们的 URL 拼写形式，而且注解含义一目了然，简单易懂；本文转载自http://www.biyezuopin.vip/onews.asp?id=15218支持同步和异步执行，使得请求变得异常简单。
App 通过 Retrofit 请求网络，实际上是使用 Retrofit 接口层封装请求参数、
Header、Url 等信息，然后使用 OkHttp 完成请求操作，然后 OkHttp 将原始的结果交给 Retrofit，Retrofit 根据用户的需求对结果进行解析。

2.4Rxjava:

RxJava 是目前比较流行的多线程的编程方式，将原本复杂的 java 多线程调

用瀑布流的方式呈现出来，简洁易用。
