title: Real time tracking in google map
body: <p>I already wrote a android apps to upload the lat and long to MySQL database(updated every 2min).</p>
  
  <p>now, i have no idea how to show the real time location on Google map in the website(php,javascript,html)
  which means how to dynamic update the Google map markers every 2 min [get the last two minutes records from MySQL database 
  and show the markers(update or disappear)] </p>
  
  <p>and after i click the marker, it should show the info[get from mysql database(not important point because it same with static Google map!?]</p>
  
  <p>just like this: <a href="http://traintimes.org.uk/map/tube/" rel="nofollow noreferrer">http://traintimes.org.uk/map/tube/</a></p>
  
  <p>I just know how to do when i just get 1 time (Static Google map!?) with my limited knowledge.</p>
  
  <p>I have already searched same question in stack overflow and google
  but i am sorry i still no idea how to do it because of my lack of knowledge.</p>
