title: How do I customize the Marker popup with Mapbox for Android
body: <p>I'm building an Android application using the Mapbox Android SDK.  I'm adding markers to the map as shown below.  How can I customize the popup so that it can have a button that will call a navigation intent?</p>
  
  <pre><code>LayerData.LayerFeature feature = layerDataArray.get(i).features.get(j);
  Marker m = new Marker(map, feature.name, feature.address1 
    + ", " + feature.address2 + ", " + feature.city + ", " + feature.state,
  new LatLng(feature.lat, feature.lng));
  m.setIcon(new Icon(this, Icon.Size.MEDIUM, 
    feature.marker_symbol, feature.marker_color));
  map.addMarker(m);
  locationItemArray.add(new LocationItem(layerDataArray.get(i).features.get(j).title, layerDataArray.get(i).features.get(j).description,
  layerDataArray.get(i).features.get(j).lat, layerDataArray.get(i).features.get(j).lng));
  </code></pre>
