title: Find out the speed of the User in android Using GPS
body: <p>I tried to find out the speed of User, while user is moving with device. Here, I followed one link with sample code. i.e: <a href="http://code.google.com/p/krvarma-android-samples/source/browse/#svn/trunk/SpeedDemo" rel="noreferrer">Here</a> SpeedDemo. </p>
  
  <p>The problem is, by using <code>location.getSpeed()</code> method, we are finding the speed. So, for that I changed the location values in device, but every time the value of the <code>location.getspeed()</code> return '0' only. Why it happen, even changing the location itself.</p>
  
  <p>Can any one known about this?</p>
