title: Updating and Synchronizing multiple GPS Geopoints in android application
body: <p>I have an <code>Android</code> Project that helps a taxi driver to get the location of the passengers who request a taxi and place them on a map , the project have two parts(seperate Project connected via a webservice) ,the passenger part which reads the <code>GPS</code> coordinates of the passenger and update it every 30 second or each 200 meter and sends the update to a web service.
  The second part is the driver part which reads the <code>GPS</code> of the driver sends it to the web service and then display only the usres who are only on the range on the map
  I have a problem that i don't know how to get the <code>GPS</code> coordinates from the two parts to the webservice exactly at the same time to set only an accurate points on the map .</p>
