title: Pinpoint current GPS location on mapview
body: <p>I have tried following many tutorials on here and on Google, but it seems like none of the tutorials relate to me.</p>
  
  <p>Basically, so far, I have been able to display the mapview on my app, and implement the setBuiltInZoomControls. I just cant get the map to pinpoint the users current location like on google latitude. </p>
  
  <p>I would like my app to detect my current position and then pinpoint it when i press a button.
  I would show you guys what I have done so far with my codes, but after attempting many tutorials, I feel my codes are now too sloppy and incomplete to understand. </p>
  
  <p>If there is any tutorial that I may have overseen, please send me the link. If not, can you please help steer me in the right direction?</p>
  
  <p>Thanks guys, happy coding!</p>
