Un broadcastReceiver può catturare più trasmissioni?

Question

Sto cercando di creare più avvisi di prossimità ma non riesco a farlo funzionare ...

Penso che il destinatario della trasmissione venga sovrascritto e quindi gestisca solo l'ultima trasmissione. Quindi se avessi due punti vicini da solo quello il cui intento è stato creato per ultimo genererà un avviso ...

Ho letto che dovrei usare i codici di richiesta ma non ho idea di come farlo ...

il mio metodo per impostare gli intenti pendenti e il ricevitore broadcast ...

private void addProximityAlert(double latitude, double longitude, String poiName, String intentfilter) { 

    Bundle extras = new Bundle(); 
    extras.putString("name", poiName); 
    Intent intent = new Intent(PROX_ALERT_INTENT+poiName); 
    intent.putExtras(extras);  
    PendingIntent proximityIntent = PendingIntent.getBroadcast(MainMenu.this, requestCode, intent, 0); 
    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 
    ); 
    requestCode++; 
    IntentFilter filter = new IntentFilter(intentfilter); 
    registerReceiver(new ProximityIntentReceiver(), filter); 
} 

la mia classe broadcastreceiver

public class ProximityIntentReceiver extends BroadcastReceiver { 

private static final int NOTIFICATION_ID = 1000; 

@Override 
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 approaching: " +intent.getExtras().get("name"), pendingIntent);  
                     //here------------------------------------- 
    notificationManager.notify(NOTIFICATION_ID, notification); 

} 

private Notification createNotification() { 
    Notification notification = new Notification(); 

    notification.icon = R.drawable.androidmarker; 
    notification.when = System.currentTimeMillis(); 

    notification.flags |= Notification.FLAG_AUTO_CANCEL; 
    notification.flags |= Notification.FLAG_SHOW_LIGHTS;   
    notification.flags |= Notification.FLAG_INSISTENT; 

    notification.defaults |= Notification.DEFAULT_VIBRATE; 
    notification.defaults |= Notification.DEFAULT_LIGHTS; 
    notification.defaults |= Notification.DEFAULT_SOUND; 

    notification.ledARGB = Color.WHITE; 
    notification.ledOnMS = 300; 
    notification.ledOffMS = 1500; 

    return notification; 
} 

} 

Potete aiutarmi per favore ??? Sono davvero bloccato con questo ...

Qualsiasi aiuto sarebbe molto apprezzato !!!
