SQLiteDatabase打開具有路徑的特定數據庫

Question

我想打開一個包含所有短消息和mms消息的數據庫。我想這樣做，因爲我需要做一個原始查詢，所以我需要得到它的工作。 我想這樣做是這樣的：

try{ 
     SQLiteDatabase sqLiteDatabase = SQLiteDatabase.openDatabase("/data/data/com.android.providers/telephony/databases/mmssms.db", null, SQLiteDatabase.OPEN_READWRITE); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 

我也得到類似這樣的錯誤：

我想知道如何正確地打開該數據庫。

Answer 1

你的問題並不新鮮。看起來你需要得到一些關於你的數據庫服務器連接是如何工作的信息。
