How to make it possible not to enter authorization data every time in Android?

Question

Android

Hello. Actually the question is in the title.
Recently got into android development. There is a client-server application. The exchange with the server takes place via json. I made authorization with registration and I would like to protect users from entering data for authorization every time the application starts.
Are there any ready-made recipes, links, code for solving this problem?
Thanks in advance to all who respond.

Why not make the "Remember me" functionality like on many sites?
