title: GPS waypoint latitude and longitude
body: <p>I am making a GPS app on my phone using the Goggle Maps SDK.  I would like to add a feature to allow the user to get the latitude and longitude for a specific point simply by taping that point on the screen.</p>
  
  <p>An example would be if there is a "what's this?" kind of function like there is on Google Maps, but on the phone version? And how would I do that in code?</p>
