 Notification notification = new Notification(R.drawable.ic_launcher,  "Notify",System.currentTimeMillis()); 
  notification.setLatestEventInfo(NotificationActivity.this, 
  "notify","Description", 
  PendingIntent.getActivity(this.getBaseContext(), 0, intent, 
  PendingIntent.FLAG_CANCEL_CURRENT)); 
      notification.number = 5;
      mManager.notify(APP_ID, notification);

When you are on the track it will alert voice navigation (ex: next you have turn left pass Taj hotel)

cool  and thanks..

Android Calculate distance between two geo location In KM

Android: calculate distance between two geo location in KM.

Below i added code for distance between two geo location in KM

Just you have to pass Start lat , lng and Destination lat ,lag value.

Screen Shot

Source Code :

    public double CalculationByDistance(GeoPoint StartP, GeoPoint EndP) {
       
        double lat1 = StartP.getLatitudeE6()/1E6;
  
        double lat2 = EndP.getLatitudeE6()/1E6;
  
        double lon1 = StartP.getLongitudeE6()/1E6;
  
        double lon2 = EndP.getLongitudeE6()/1E6;
  
        double dLat = Math.toRadians(lat2-lat1);
  
        double dLon = Math.toRadians(lon2-lon1);
  
        double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
  
        Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
  
        Math.sin(dLon/2) * Math.sin(dLon/2);
  
        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));

//6378.1 is gravity of earth
        return  c*6378.1;
  
     }
