Crash. UnknownHostException when there is no connection.

That's how I use map in my app:

     private com.esri.android.map.MapView _mapView;
     ////////////////////////////////////////////////////
    _mapView = (com.esri.android.map.MapView) view().findViewById(R.id.map);
    _tiledMapService = new ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer");

   _mapView.addLayer(_tiledMapService);
   /////////////////////////////////////////////////////

Then when there is no internet connection app crashes with Log:

As I see the crash caused by arcgis lib. So I can't catch it in my app.

Is there way to use arcgis runtime sdk with bad connection without crash?

PS Tested on the real device not emulator.
