Hi guys,

I am trying to create a an application similar to the UC2012 android application by ESRI. I show some relevant places in an ERSI map using some pin graphics. Now i want to create a callout when the use touches these 'pins' similar to UC2012 app. I am able to display a callout at random points specifed through code and I know how to use the 'onsingletaplistener' but  I couldnt find any function that  detects whether the touch was over the graphics. Can some one help me out?

Basically I am looking for a convenience function to detect whether the touch occurred over a graphic(with PictureMarkerSymbol).
Thanks in Advance
