首先，把簡訊資料庫匯出來

安卓資料庫的名字叫mmssms.db，在/data/data/com.android.providers.telephony目錄下，該目錄需要手機root之後才能看

用SQLite DataBase Browser開啟

如圖，一共有這麼多的表：

但是真正有用的只有3個，

Canonical_addresses表————如下：_id對應threads表裡面的recipient_ids，address對應sms表裡面的address

Threads表————這個相當於手機打簡訊後按聯絡人分的組的那個介面，是按聯絡人分的會話列表

Sms表————手機所有簡訊都在這裡

接下來，需要了解一些基本的知識

ContentResolver

Cursor

這個可以自己從網上搜看看

下面是部分關鍵程式碼，所有的在我的上傳裡能搜到：

從threads表獲取日期，訊息數量，部分訊息內容，從sms表裡面取得threads裡_id對應的電話號碼
