Sessions on a web service for an Android application, are they needed?

Question

Android

Help me figure it out. I'm new to this business. I have a web service that saves user registration data and their messages (service order, text) in the database. An android application should be able to register a user, log in and send a message to the web service (order for the user). Do I need to create sessions...authorization token....etc?

Answer 1

Not sure if sessions are needed.
And the token is needed, after logging in on the android, the token is followed by the server api.

Answer 2

Read about RESTful API
As one pavel rightly said , you don’t need sessions, just sign requests with a token and most importantly, don’t bother and don’t be afraid of tricky names in bourgeois, everything is actually very simple and the simpler and more logical the client will work with the server, the better)
