title: What is the grid behind the map in an Android app developed with the ArcGIS SDK for Android?
body: <p>I am creating a simple mapping app using the ArcGIS Runtime SDK for Android. I created a <code>MapView</code> and added a tile package (.tpk) to it as its base map. The picture below is how it appears on the screen. Can anyone tell me why there is a grid above and below my map and how to remove it? I thought it was the <code>MapView</code>'s grid so I tried calling <code>mapView.getGrid().setVisible(false)</code>, but the grid still appears.</p>
