I have been working on android for some time and i wondered today that :

Why do we make a Singleton Class for Retrofit Client?

What happens if we don't?

CodePudding user response：

It is very simple,

Singleton class is used for this, so that only one object can be created at a time so this helps us in memory management.

If you don't make a class singleton then multiple instances will be created and if you don't trash those objects even by mistake then it will hold a lot of memory which is not good.
