title: Get current location (lat,long) in android google map when app start
body: <p><strong>FYI:</strong> <em>I've searched for an appropriate answer but couldn't find one. Most of them are old and used deprecated methods.</em></p>
  
  <p>What I need is, when the app start it will display google map with marker at the current position. I can set marker using latitude and longitude. But, I couldn't find any way of getting current lat-long using <strong>GPS</strong>.</p>
  
  <p>Could you please help me to get the current lat-long using GPS?</p>
  
  <p>Thanks in advance.</p>
