Which is faster retrieving data from internet or from database in android app?

Question

I am creating a quiz app which is for now retrieving list of data objects from retrofit and as data is asynchronous , it takes 2 or 3 seconds to retrieve it.

But there are apps which are using databases instead of retrieving whole sum of data from internet. As i have never worked with android sq-lite which is better for performance and will produce efficient results?

What are your opinion do i have to change my app and work with sq-lite instead of retrofit.

Answer 1

为了获得更快的数据，您可以使用改造 REST API 进行实时存储，使用 Room 数据库进行本地存储，而不是使用 SQLite 数据库。

Answer 2

Getting value from local database is faster. But when working online you have other benifits. You have to figure out what fits you better.
