geolocation - How to get current location on android -


Hey guys, I want to get the latitude and longitude of the users' location. I have tried to overflow the developers site and stack, some examples are loaded on the user who runs something: - onLocationChanged () I do not need location updates, the user can now take a minute or two minutes Will need to know the location of the time i started the location and what if the user has never used any geographic location app before, then i Also would like an option for LocationManager.getLastKnownLocation ()

My code is: - 

  Location Manager LM = (Location Manager) getSystemService (context.LOCATION_SERVICE); // Connect to GPS location service location public = lm.getLastKnownLocation (lm.NETWORK_PROVIDER); Toast. Make text (current location, "latitude ->" + double.toastring (loc.getLatitude (+) + "longitude -> gt; double +string (loc.getLongitude ()), toast .LENGTH_LONG ) Showing ();   
 and is working fine but I'm afraid that getLastKnownLocation may be zero when the first time it is used.  
 Thanks   
 
 
 Sign up for location updates and once you first If you receive the update, you can cancel the registration for future updates.  
 In other words, create a  LocationListener  and assign it to your  location manager  's  request location update  method. In the  onLocationChanged  your  LocationListener , call the  removeUpdates  method to your  LocationManager ,  this  parameter.  
 Before you take some time to get a new position, but there is actually no alternative to using  getLastKnownLocation .
