Question

I want to display 5 images on a Map View as map overlay with an interval of 1 minute each. I use sleep to make a delay. But it is not working. After all delay, the images are displaying altogether. How to do this? Please help

Look at this link. I think, it is, what you need

http://developer.android.com/resources/articles/timed-ui-updates.html

UPD:

Define in your activity:

private Handler mHandler = new Handler();
private int cnt = 0;

private Runnable mUpdateTimeTask = new Runnable() {
   public void run() {

      if (cnt < 5)
      {     
         // Display new Image
         mHandler.postDelayed(mUpdateTimeTask, 60000);
         cnt++;
      }
      else
      {
         mHandler.removeCallbacks(this);
      }
   }
};

and call then somwhere in onCreate or onResume

mHandler.postDelayed(mUpdateTimeTask, 60000);
