title: How do I keep my Android app continuously connected with my own RESTful API to retrieve data continuously?
body: <p>Please help me guys ! Please </p>
  
  <p>I am using <em>retrofit</em> to connect with my RESTful API which is running on Express and Node. Now I want to fetch my data from api continuously means there should be a continuous connection of my app with api.</p>
  
  <p>Retrofit enqueues the requests and we need to keep it sending again and again. I've tried by creating a retrofit call inside a services but it reflects the UI constantly which means it makes call continuously.</p>
  
  <p>So how can I do that? DO I need to make my restful service a real-time? or is there any way to make this calls? (Please don't tell me about Firebase or Parse or Anything)  </p>
