What are the architectural principles for building a backend component for mobile Android / iOS applications?

Question

Mobile development

Hello!
Recently, I have turned my eyes towards development for the web and mobile devices. Now I'm still studying RoR, in the future, programming for iOS and Android. Now I want to start creating a web service application on rails with the possibility of its further use as a data source for mobile platforms. Question - is it possible? I assume so, so the question is - tell me what to read on this topic, in order to initially lay the right principles and technologies in my service, set the direction for searching and studying.
Thank you!

Rails supports REST out of the box, so a web service can be built in this paradigm. I personally found this book very helpful.
It describes the basics of building a rest API in general, without being tied to specific technologies.
You need to start by designing a REST API. For implementation on rails, you can first use the out-of-the-box jbuilder, a fairly simple and convenient thing.
