I used below code for displaying notification in notification Bar.
it worked fine.
But i need to display notification icon dynamically that will come from w
just add some icons in your resource folder and then
int myIcon = R.drawable.image;
your logic goes here ....
and change value of icon according to your logic like myIcon = R.drawable.somenewimage;
and then finally set your notification
Notification note = new Notification(myIcon,"status message", System.currentTimeMillis());
