title: Generate a Popup window in Android Map App using Mapbox SDK
body: <p>I am developing a map app in Android using Mapbox Android SDK. I want to creat a popup on map when tap on map. Please note that not on any icon or marker. The popup should appear at the pin point of tapping position. The position information in longitude and latitude can be get from the following code.</p>
  
  <pre><code>@Override
              public void onTapMap(MapView pMapView, ILatLng pPosition) {
                  String coords = String.format("Zoom = %f, Lat = %f, Lon = %f", pMapView.getZoomLevel(), pPosition.getLatitude(), pPosition.getLongitude());
                  String utfGrid = MapboxUtils.getUTFGridString(pPosition, Float.valueOf(pMapView.getZoomLevel()).intValue());
                  Log.i("TapForUTFGridTestFrag", String.format("coords = '%s', UTFGrid = '%s'", coords, utfGrid));
                  Toast.makeText(getApplicationContext(), coords + " == " + utfGrid, Toast.LENGTH_LONG).show();
              }
  </code></pre>
  
  <p>I am actually want to get the following design. the red popup window's lower pin will be positined at the tapping position.</p>
