Android ContentProvider（類容提供者）之操作通訊錄聯繫人 添加查詢聯繫人

Android系統一般自帶有：電話，郵件，瀏覽器功能；在電話通訊錄及通信記錄，均是以ContentProvider的形式向外來應用共享，所以我們要訪問和操作通訊錄，就需要通過ContentProvider實現。

操作通訊錄：邏輯
- 首先需要知道Android系統的通訊錄ContentProvider清單類容
- 然後獲得其唯一標示
- 再然後去獲得通訊錄ContentProvider的業務路徑
- 最後去操作通訊錄的ContentProvider

查看Android自帶電話通訊錄源代碼，得到ContentProvider如下：
