將數據存儲在共享偏好和數據庫之間的差異android

我正在android中創建一個應用程序，我想存儲在谷歌地圖上選擇的地方用戶的數據。我目前通過將它們全部添加到一個數組中存儲所有的地方，然後通過Gson庫對它們進行序列化，並且它工作正常，並且編碼非常簡單和容易，但是如果我使用數據庫而不是那個那麼編碼將會更加複雜，因爲數據庫的植入更爲複雜，那麼只需將這些地方的數組串聯起來就可以共享偏好。下面是我的對象是存儲和保存在共享偏好的類，但如果想要將它們存儲在數據庫上，那麼我必須經歷更復雜的創建查詢插入，刪除更新等，所以建議我我應該使用db還是shred首選項可以很好地保存位置列表。將數據存儲在共享偏好和數據庫之間的差異android
