title: What is the way to run a new thread and a UI thread in Android?
body: <p>As far as I can understand in android when we are running processes they start off in the Main thread. When we are doing some heavier work we use a new thread. If we like to modify the UI appearance we use the run on UI.</p>
  
  <p>Can someone explain to me what these threads do and how they are used?</p>
