How to optimize cards in Android and IOS application?

Question

Java

How to properly optimize images in the application itself and in the database ?? What are the methods or ways to optimize?

Answer 1

Not sure what "optimize" means? the files themselves? so you don't really optimize them. Access to them? For DB, make indexes, for a cache client or a local database, so as not to load it every time. You can pre-load and save before you need to display.

Answer 2

It's interesting to hear for yourself about optimization methods in the application....
I usually optimize images outside the application...
