Android：試圖寫一個只讀數據庫

我有一個sqlite數據庫文件，我無法讀寫這個數據庫文件。我使用這個代碼：Android：試圖寫一個只讀數據庫

fileIsExists = new File(Environment.getExternalStorageDirectory() 
      + "/bbmp/bbmp2.sqlite"); 
    if (fileIsExists.exists()) { 
db = SQLiteDatabase.openDatabase(fileIsExists.toString(), null, 
       SQLiteDatabase.OPEN_READWRITE);   
}

此擲以下錯誤：
