Excerpt -  try                      cnt   scnt   now System currentTimeMillis   r rand nextInt 6  r                loc lm getLastKnownLocation best               if loc  null  lat loc getLatitude   lng loc getLongitude                  Thread sleep 100               handler sendMessage handler obtainMessage                         catch  InterruptedException e                         Toast makeText this   Error   e toString    Toast LENGTH LONG  show                As you can see above  a thread is running alongside main thread of user-interface activity which continuously displays GPS lat long alongwith current time and a random dice throw    IF you are curious then just check the full code  GPS Location with a randomized dice throw  amp  current time in separate thread

The initial issue is solved by changing lat and lon to double   I want to add comment to solution with Location location   locationManager getLastKnownLocation bestProvider   It works to find out last known location when other app was lisnerning for that  If  for example  no app did that since device start  the code will return zeros  spent some time myself recently to figure that out    Also  it s a good practice to stop listening when there is no need for that by locationManager removeUpdates this    Also  even with permissions in manifest  the code works when location service is enabled in Android settings on a device

Give it a try     public LatLng getLocation                 Get the location manager      LocationManager locationManager    LocationManager  getSystemService LOCATION SERVICE        Criteria criteria   new Criteria         String bestProvider   locationManager getBestProvider criteria  false        Location location   locationManager getLastKnownLocation bestProvider        Double lat lon       try          lat   location getLatitude            lon   location getLongitude            return new LatLng lat  lon               catch  NullPointerException e            e printStackTrace           return null

Here s your problem   int latitude    int   location getLatitude     int longitude    int   location getLongitude       Latitude and Longitude are double-values  because they represent the location in degrees    By casting them to int  you re discarding everything behind the comma  which makes a big difference  See  Decimal Degrees - Wiki
