title: map.setMyLocationEnabled(true); is not working
body: <p>I have just started working on a android project and is using the Google Map API. </p>
  
  <p>I am able to fetch the map on my app but when i try to enable the current location with <code>map.setMyLocationEnabled(true);</code>, the app says unfortunately app has stopped working. </p>
  
  <p>When I removed the line <code>map.setMyLocationEnabled(true);</code> then it worked fine. Can anyone please help me to get the current location button enabled.</p>
