title: Every Activity in Android is a Process,or One Application is one process
body: <p>In this page, <a href="http://androidapps.org.ua/androidintro_ipc.html" rel="noreferrer">http://androidapps.org.ua/androidintro_ipc.html</a> , intent switching between activities is described as Inter Process Communication. Now  I am confused whether every activity is a separate process in android or All activities inside an application is one process. I have checked the process id of all activities and service in my Application using: </p>
  
  <pre><code> int id = android.os.Process.myPid();
   System.out.println("Process id of Activity1 :"+id);
  </code></pre>
  
  <p>But it is showing same process id.
  Please reply back.</p>
