title: MVC like logic separation of Android apps
body: <p>I recently began to make my first Android app, and, while learning the tricks, I messed up my code by not separating the logic. Then I wondered if there exists some sort of standard for logic separation on Android (like MVC). I would really appreciate if you could show me some ways of packaging my app in a MVC manner, or some other pattern, if any.</p>
  
  <p>Thanks</p>
