Android SQLCipher和资产文件夹中的数据库

At the moment, my sqlite db file is NOT encrypted and it's copied from the assets folder to the application data/data/mypackage/databases folder.

目前，我的sqlite db文件未加密，而是从assets文件夹复制到application data / data / mypackage / databases文件夹。

Now I want to add the SQLCipher libraries to my project and start using them. Can I encrypt the db file and copy it to assets and use the same key inside the application? Is it possible to encrypt the database on Windows? What I need to do?

现在我想将SQLCipher库添加到我的项目中并开始使用它们。我可以加密db文件并将其复制到资产并在应用程序中使用相同的密钥吗？是否可以在Windows上加密数据库？我需要做什么？

i think we should do like that

我想我们应该这样做

SQLiteDatabase normalDB = null;
SQLiteDatabase cryptedDB = null;
normalDB = SQLiteDatabase.openDatabase(dbPath, "", null,
    SQLiteDatabase.OPEN_READONLY
    | SQLiteDatabase.NO_LOCALIZED_COLLATORS);

cryptedDB = SQLiteDatabase.openOrCreateDatabase(
    encrypteddbPath, Constants.CRYPT_KEY, null);

Cursor cursor;

cursor = normalDB.query(TABLE_CITY,
new String[] { FIELD_CITY_CODE, FIELD_NAME1,
    FIELD_NAME2, FIELD_NAME3 }, null, null, null,
    null, null);
int i = cursor.getCount();
while (i > 0) {
    ContentValues newLabelValues = new ContentValues();

newLabelValues.put(FIELD_CITY_CODE, cursor.getString(0));
        newLabelValues.put(FIELD_NAME1, cursor.getString(1));
        newLabelValues.put(FIELD_NAME2, cursor.getString(2));
        newLabelValues.put(FIELD_NAME3, cursor.getString(3));
        cryptedDB.insert(TABLE_CITY, null, newLabelValues);

cursor.moveToNext();
}
