title: Use Android Device Sensors To Measure Distance
body: <p>I have started programming an Android Application to <strong>Measure short distances (in Meters)</strong> between two points so for example the user hits a start button then the application saves the current Location then while the user is walking the application shows him the distance in <strong>meters</strong> from the starting point.</p>
  
  <p>How to achieve that <strong>considering not to use GPS or Networking</strong> ? I have searched around in Google and SO. I think <strong>Motion Sensors and Accelerometers</strong> are not the way to go but found nothing about Position Sensors like <strong>Orientation Sensor and Geomagnetic Field Sensor</strong>. Can I use Position Sensors to Achieve the case described above?</p>
