If you are using eclipse did you try to clean the project ? I think on the menu item. Project: Clean and then select the project you would like to clean.

Looking at your code closer I see there is some logic errors here. You have an array of coordinates where lat and lng is separated by comma, but the way you assigned to lat and lng, you are using 2 different coordinates from the array ?

What you really want is
lat = Double.parseDouble(coordiantes[0].split(",")[0]);
lng = Double.parseDouble(coodinates[0].split(",")[1]);

Still this will only show one coordinate on the map not all of your coodinates.

The way you have it now, the program will throw an exception. (NumberFormatException ??)

What I want the code to do is select one location at a time and give directions to it based on the current location. How far is my code from this??
 
I think you are looking to do something like this

:)

Based on your code posted here, you got a long way to go. First look for sample code on using GPS to detect where you are. I think you want to use google as your friend for code sample.

When I started to code up the App above a year ago I started with no JAVA or Andriod knowlege. So it is not hard, just take some time to sink in.

Good luck.
