内容提供商结果
是门面，它定义了一种应用程序之间共享数据。你很多附加本地数据库您的应用程序或创建映射到一个通用数据库内容提供商，使所有在同一台设备上的应用程序可以共享它。
Content Provider
is a facade and it defines a way to share data among applications. You many attach a local database to your app or create Content Provider mapped to a universal database so that all the application on the same device can share it.
服务结果
是需要从主要活动脱钩长时间运行的进程。它具有本地和远程服务。本地服务类的本地数据库，远程服务就像是内容提供商共享该数据库的信息。
Service
is long running processes that need to be decoupled from main activity. It has local and remote service. local service is like the local database, and remote service is like Content Provider sharing the database info.
什么我的应用程序在做什么？结果
下载信息。在后台的多个互联网资源（我想这将是服务）和存储信息。进入数据库，多个应用程序需要检索数据，格式化它们，它们输出到用户（我想这将是一个内容提供商）。
What My App is doing?
downloads info. from multiple internet resource in the background (I suppose this will be Service) and store the info. into database, and multiple applications will need to retrieve the data, format them and output them to user (I guess it will be a Content Provider).
