title: Create an array of markers Google Maps V2
body: <p>Good afternoon. In my application I extract data from the database for the markers on parse.com : </p>
  
  <pre><code>public void ParseQueryMap() {
            ParseQuery query = new ParseQuery("MyObject");
            query.findInBackground(new FindCallback() {

                           int distance = (int)aLocation.distanceTo(bLocation);
                                if (distance&lt;rad) {  // where "rad" radius display points
                                    myMap.addMarker(new MarkerOptions().position(new LatLng(geo1Dub,geo2Dub)).title(commGet)                                   .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)));

  <p>I want to create an array of markers to test its size, and if it is zero, then show AlertDialog. That is, I want to know how many bullets I got. Thank you for your help</p>
  
  <p><strong>UPDATE:</strong> I want to know how many markers shown on the map</p>
