Changing the GPS coordinates with out moving anywhere
<blockquote>
  <p><em>*</em>*i have used the gps coordinates for calculating the distance using location updates. but problem is that if i am standing at same place the coordinates changes and distance is changing with out moving anywhere. I want to change it only when I have moved min 10 mtrs.</p>
