android如何使用BroadcastReceiver后台实现来电通话记录的监听并存取到sqllite数据库通过Contentprovilder实现接口

BroadcastReceiver 是android四大组件的一个，本质上是一种全局的监听器，用于监听全局的广播消息。下面实现了后台监听android手机通话记录。本demo分两个程序，第一个程序是设置监听器，然后模拟器重启后就会有一个全局的service在后台监听你的来电显示，大多数通话管理软件都是这么干的，第二个项目是获取通话记录的，由于只是做一个小实验，所以是根据某个项目改的，里面涉及到一些ContentPrivler的知识，还有sqllite数据库，里面定义名称并非其意思。
