title: set 2 proximity alerts with the same broadcast
body: <p>I create a proximity alert in this way</p>
  
  <pre><code>    private void setProximityAlert(float radius, double lat, double lng, String place)
  {
      long expiration = -1;
      LocationManager locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
      Intent intent = new Intent(TREASURE_PROXIMITY_ALERT);
      intent.putExtra("lat", lat);
      intent.putExtra("lng", lng);
      intent.putExtra("place", place);
      PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), -1, intent, 0);   
      locManager.addProximityAlert(lat, lng, radius, expiration, pendingIntent);
  }
  </code></pre>
  
  <p>and on my activity I registered the receiver in this way</p>
  
  <pre><code>    IntentFilter intentFilter = new IntentFilter(TREASURE_PROXIMITY_ALERT);
      registerReceiver(new ProximityIntentReceiver(), intentFilter);
      setProximityAlert(10, 45.150344, 9.999815, "POINT1");
  </code></pre>
  
  <p>and my broadcast receiver is correctly called.
  So now, I want to add another proximity alert, is it possible? I want that the same boadcast receiver is called by 2 proximity alert.
  I made this:</p>
  
  <pre><code>    IntentFilter intentFilter1 = new IntentFilter(TREASURE_PROXIMITY_ALERT1);
      registerReceiver(new ProximityIntentReceiver(), intentFilter1);        
      setProximityAlert(200f, 45.143848, 10.039741, "POINT2");
  </code></pre>
  
  <p>but it does not work, nothing happen. I'm really now on it and I was wondering if it is the right way. My intent is trigger 2 alerts, one when GPS get the position POINT1 and another one at the position POINT2.
  Any helps are welcome.</p>
