I Embed GE in my app and try to plot some driving route on it. I tried Place marks and "Line String" coordinates to plot that. what I am looking for is a way that I update the plot and plot a new route by new coordinates, So I need a way to delete old place marks and plot new one by "KML" code or other programing techniques.
In other word I want to delete temporary places folder by programming instead of GUI "Delete Contents" in GE.
Any help is appreciated. thanks ....
