Android ContentProvider（类容提供者）之操

Android系统一般自带有：电话，邮件，浏览器功能；在电话通讯录及通信记录，均是以ContentProvider的形式向外来应用共享，所以我们要访问和操作通讯录，就需要通过ContentProvider实现。

操作通讯录：逻辑

• 首先需要知道Android系统的通讯录ContentProvider清单类容
• 然后获得其唯一标示
• 再然后去获得通讯录ContentProvider的业务路径
• 最后去操作通讯录的ContentProvider

查看Android自带电话通讯录源代码，得到ContentProvider如下：
