title: What's message queue in Android?
body: <p>Can someone explain what's the message queue in Android? Is it the list of processes running? I can't find a good source explaining it.  </p>
  
  <p>I am asking because I was reading about the method post of the class View. </p>
  
  <p><a href="https://developer.android.com/reference/android/view/View.html" rel="noreferrer">POST</a> </p>
  
  <p>added in API level 1
  boolean post (Runnable action)</p>
  
  <blockquote>
    <p>Causes the Runnable to be added to the <strong><em>message queue</em></strong>. The runnable
    will be run on the user interface thread.</p>
  </blockquote>
  
  <p>Thank you in advance.</p>
