不要从外部存储打开数据库

Question

我需要从文件（例如sdcard的示例）打开Sqlite数据库。 我得到了Uri：

          Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
          intent.setType("*/*");

接下来我尝试：

 sqLiteDatabase = SQLiteDatabase.openDatabase(uri.getPath(), null, 
 SQLiteDatabase.OPEN_READONLY);

并得到错误：

 E/SQLiteLog: (14) cannot open file at line 35803 of [605907e73a]
  (14) os_unix.c:35803: (2)
