Where is an example of using Robospice + OAuth?

Question

Android

I'm trying to figure out how to work with REST on android. I decided to try using Robospice, but I can’t understand how it looks in practice when using OAuth (what a competent architecture looks like, where to save the token, etc.): it’s still a mess in my head. Maybe someone will share an example of a client logging in via OAuth and then making some requests to the server?
The choice of Robospice is not justified by practical experience, something else is possible, the main thing is that all the nuances with the Activity life cycle are taken into account.
