title: Reload only UI, not main view on an Android app
body: <p>I'm making a video app in Android Studio and having problem with moving between profile and landscape orientation where the whole activity is being reloaded. </p>
  
  <p>I want only to reload the UI layout while flipping the phone without having to reload the main View that streams my video from my main Activity. I have two layout, one for profile and one for landscape (in each respective catalog; layout and layout-land), and they're being reloaded correctly on tilting the phone. But how do I still keep the video from playing without reloading with the main activity?</p>
  
  <p>I've tried to look into Fragments, but it only keep the UI element from not being reloaded and not the main activity. Am I missing something fundamental here? </p>
