Android Location Manager

Download a gpx file and put in any folder, in this case GPX Files folder. Then load it from DDMS Emulator GPX tab.

Below is the main activity file. No xml layout file needed. Run the bottom part of GPX file which is collection of points by clicking on the play button of the DDMS. This simulates GPS tracking.
