You can use this library
https://github.com/MoeidHeidari/LocationTracker
public class MainActivity extends AppCompatActivity {
LocationTracker tracker;
@OverRide
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tracker =new LocationTracker(this);
Toast.makeText(this, String.valueOf(tracker.getLatitude()),
Toast.LENGTH_LONG).show();
tracker.setOnLocationChanged(new OnLocationChanged() {
@OverRide
public void OnChange(Location location) {

            //Write your codes here
        }
    });


}

}
