title: specify the name of country using longitude and latitude on android
body: <p>I'm using google api 15 on android emulator.</p>
  
  <p>I want to specify a country from a map by using a touch to the screen,
  So if I made a touch to the screen on some longitude and latitude, I can know to what country or a city those belong to?</p>
  
  <p>.. Thanks a lot.</p>
