Hello, here is the code that worked for me, I followed the feature-layer-show-attributes sample exactly, only implementing it for two layers instead of one:  public class MainActivity extends AppCompatActivity {     // existing map references     private MapView aMapView;     private LocationDisplay mLocationDisplay;     private Spinner mSpinner;     // request codes from Android     private int requestCode = 2;     String[] reqPermissions = new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission             .ACCESS_COARSE_LOCATION};     // popups     private Callout aCallout;     private ServiceFeatureTable table0, table1;     // private static final String sTag = "Gesture"; @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     // get the Spinner from layout     mSpinner = (Spinner) findViewById(R.id.spinner);     // inflate MapView from layout     aMapView = (MapView) findViewById(mapView);     final ArcGISMap map = new ArcGISMap(Basemap.Type.DARK_GRAY_CANVAS_VECTOR, 48.6596, -113.7870, 9);     aMapView.setMap(map);     // get the callout that shows attributes     aCallout = aMapView.getCallout();     // layer 0, facilities     table0 = new ServiceFeatureTable(getResources().getString(R.string.layer0_url));     FeatureLayer featureLayer0 = new FeatureLayer(table0);     map.getOperationalLayers().add(featureLayer0);     // get the callout that shows attributes     aCallout = aMapView.getCallout();     // layer 1, trails     table1 = new ServiceFeatureTable(getResources().getString(R.string.layer1_url));     FeatureLayer featureLayer1 = new FeatureLayer(table1);     map.getOperationalLayers().add(featureLayer1);     // set an on touch listener to listen for click events     aMapView.setOnTouchListener(new DefaultMapViewOnTouchListener(this, aMapView) {         @Override         public boolean onSingleTapConfirmed(MotionEvent e) {             // remove any existing callouts             if (aCallout.isShowing()) {                 aCallout.dismiss();             }             // get the point that was clicked and convert it to a point in map coordinates             final Point clickPoint = aMapView.screenToLocation(new android.graphics.Point(Math.round(e.getX()), Math.round(e.getY())));             // create a selection tolerance             int tolerance = 10;             double mapTolerance = tolerance * aMapView.getUnitsPerDensityIndependentPixel();             // use tolerance to create an envelope to query             Envelope envelope = new Envelope(clickPoint.getX() - mapTolerance, clickPoint.getY() - mapTolerance, clickPoint.getX() + mapTolerance, clickPoint.getY() + mapTolerance, map.getSpatialReference());             QueryParameters query = new QueryParameters();             query.setGeometry(envelope);             // request all available attribute fields             final ListenableFuture<FeatureQueryResult> future_0 = table0.queryFeaturesAsync(query, ServiceFeatureTable.QueryFeatureFields.LOAD_ALL);             final ListenableFuture<FeatureQueryResult> future_1 = table1.queryFeaturesAsync(query, ServiceFeatureTable.QueryFeatureFields.LOAD_ALL);             //print all available attr fields in logcat             System.out.println(future_0.toString());             Log.d("FUTURE0", "see ^");             // example return: com.esri.arcgisruntime.data.ServiceFeatureTable$4@36c3a76             System.out.println(future_1.toString());             Log.d("FUTURE1", "see ^");             // add done loading listener to fire when the selection returns             future_0.addDoneListener(new Runnable() {                 @Override                 public void run() {                     try {                         //call get on the future to get the result                         FeatureQueryResult result = future_0.get();
