Proximity Alert giving no notifications

Question

I want to be notified when user enters particular area , but it is not working, yet I receive no error! I am stuck here for the past a week , kindly cooperate with me!

 public class MainActivity extends FragmentActivity{


protected GoogleMap gMap;
private LocationManager locationManager;
 TextView txt;
double clat,clong;

private static final String PROX_ALERT_INTENT ="com.example.map.ProximityAlert";



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    gMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
    if (gMap == null) {
            Toast.makeText(this, "Google Maps not available",           
         Toast.LENGTH_LONG).show();}


    txt=(TextView) findViewById(R.id.text1);



    locate();



    gMap.setMyLocationEnabled(true);
  }    

 private void locate() {


    locationManager = (LocationManager)    getSystemService(Context.LOCATION_SERVICE);

    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {

            clat=location.getLatitude();
            clong=location.getLongitude();         
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {}
        public void onProviderEnabled(String provider) {}
        public void onProviderDisabled(String provider) {}
      };

      locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 10, locationListener);
      addProximityAlert(clat,clong);

  }
      private void addProximityAlert(double latitude, double longitude) {

          Intent intent = new Intent(PROX_ALERT_INTENT);

                  PendingIntent proximityIntent = PendingIntent.getBroadcast(this, 0, intent,PendingIntent.FLAG_CANCEL_CURRENT);

                  float POINT_RADIUS=10000;
                long PROX_ALERT_EXPIRATION=10000;
                locationManager.addProximityAlert(

                      latitude, // the latitude of the central point of the alert region

                      longitude, // the longitude of the central point of the alert region

                      POINT_RADIUS, // the radius of the central point of the alert region, in meters

                      PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration

                      proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
                 );
                 IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT); 
                 registerReceiver(new ProximityIntentReceiver(), filter);
              }
    }

Here is the Proximity receiver class ,

    public class ProximityIntentReceiver extends BroadcastReceiver {

private static final int NOTIFICATION_ID = 1;

    @SuppressWarnings("deprecation")
    public void onReceive(Context context, Intent intent) {

        String key = LocationManager.KEY_PROXIMITY_ENTERING;

        Boolean entering = intent.getBooleanExtra(key, false);



        if (entering) {

            Log.d(getClass().getSimpleName(), "entering");

        }

        else {

            Log.d(getClass().getSimpleName(), "exiting");

        }

        NotificationManager notificationManager =
            (NotificationManager)    context.getSystemService(Context.NOTIFICATION_SERVICE);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, null, 0);       
        Notification notification = createNotification();
        notification.setLatestEventInfo(context,"Proximity Alert!", "You are near your point of interest.", pendingIntent);
        notificationManager.notify(NOTIFICATION_ID, notification);
    }
    private Notification createNotification() {
        Notification notification = new Notification();
        //notification.icon = R.drawable.image_1.jpg;
        notification.when = System.currentTimeMillis();
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.flags |= Notification.FLAG_SHOW_LIGHTS;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notification.defaults |= Notification.DEFAULT_LIGHTS;
        notification.ledARGB = Color.WHITE;
        notification.ledOnMS = 1500;
        notification.ledOffMS = 1500;

        return notification;
    }
  }

Are you using the new Location API? There's a nice tutorial here (official doc) about geofences: https://developer.android.com/training/location/geofencing.html
