I like to develop a small application, that can read out a XML File with coordinates (a track) and compare them with my current position. If the first coordinate is reached (within a specific range) it should display my next waypoint.
I'm not familiar in Java, because I'm a web developer and usually programming PHP.
So it would be very nice, if you can help me.
I have to do these steps:
1. choose a xml file (like file->open)
2. load its content dynamically
3. get current position and compare with next waypoint
First of all, I have to create a button and attach an onClick event, right?
How I can call a fileselector afterwards?
Thank you very much for your help and best regards from Germany.
