解决方案
与Android，它实际上是pretty容易，以获得从GPS服务的位置。使用的LocationManager 最简单的方法来做到这一点。
的LocationManager =（的LocationManager）getSystemService（Context.LOCATION_SERVICE）;customLocationListener =新CustomLocationListener（）;locationManager.requestLocationUpdates（
LocationManager.GPS_PROVIDER，
0，
0，
二）;
....一个Spagehtti code GOES HERE .....
类CustomLocationListener实现LocationListener的{............
公共无效onLocationChanged（位置argLocation）{
如果（位置！= NULL）{
INT纬度=（INT）（argLocation.getLatitude（）* 1E6）;
INT经度=（INT）（argLocation.getLongitude（）* 1E6）;
}
}} ........

解决方案
With android it is actually pretty easy in order to get the location from the GPS Service. Use the LocationManager the easiest way to do it
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
customLocationListener = new CustomLocationListener();
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
0,
0,
ll);
....A Spagehtti CODE GOES HERE.....
class CustomLocationListener implements LocationListener{ ............
public void onLocationChanged(Location argLocation) {
if(location != null) {
int latitude=(int)(argLocation.getLatitude()*1E6);
int longitude=(int)(argLocation.getLongitude()*1E6);
}
} ........ }
