title: Forcing admob to refresh ad every second in Android
body: <p>I have built an android app which has a fixed screen that will remain focused for more than a minute. Kind of a story in the page.</p>
  
  <p>I have integrated Admob adrequest into the application. But it is the single ad that comes on load of the screen and remains till I quit.</p>
  
  <p>Can I do something so that the Ad will change every 1 sec.</p>
