title: Multiple Instances of an Activity
body: <p>I am trying to show the user information on incoming-call screen, whenever there is an incoming-call. So I have a broadcast receiver listening to incoming calls, which starts the intent service, which subsequently starts an activity (<em>with Theme Dialog</em>). </p>
  
  <p>Now, whenever there is an incoming-call, my activity dialog pops up and shows as intended.</p>
  
  <p><strong>Problem</strong>:  When the activity dialog is already on the screen and incoming-call happens, there is no new activity dialog with new information. I guess that whenever there is an instance, Android does not creates the new one.  So it seems like my problem is "<em>creating multiple instances of an activity</em>".</p>
  
  <p>Please note that I am starting an activity from an intent service using <strong>FLAG_NEW_TASK</strong>.</p>
