GPSTracker.java 		object that keeps track of GPS (from open source)
can be used as: 
//        GPSTracker gps = new GPSTracker(MyActivity.this);
//        if(!gps.canGetLocation()) {
//            gps.showSettingsAlert();
//        }
//
//        double latitude = gps.getLatitude();
//        double longitude = gps.getLongitude();
//        Log.v("MyActivity", "latitude: " + latitude + " longitude: " + longitude);

// It somehow worked without setting service but the location update has to be 
// in main thread otherwise I'll get an error.
