The code bellow tries to ask the user to upload kml file and then saves the file at the same time it shows the kml data in google maps using google maps api v2. I could successfully take the kml file and saves it at a specific directory, HOWEVER, i am facing some problem in displaying the file on google maps immediately after the user clicks on KML TEST button. The error is Uncaught ReferenceError: showKML is not defined
Here is the code that I used
