title: PopUp dialog Android from background thread
body: <p>I need a popup dialog to be shown when i get a message from different thread but the dialog should be not dependent on Activity i.e, it should display the dialog wherever the screen focus is. </p>
  
  <p>Can it be done? Because the dialog is handled per Activity, I thought of using a service but again it would be one more thread added and I want to avoid that. </p>
  
  <p>Any other options available?</p>
