At the 100.4 release, do you support the rubberband aoi box to zoom in (in 10.2.4 this was called ZoomBoxOverlay).

At the 100.4 release, do you support the rubberband aoi box to zoom in (in 10.2.4 this was called ZoomBoxOverlay). This is a very useful capability and I would hope their is similar functionality at 100.4.

What is mapview.setEnableTouchZoom(true).

Sorry, zoom box is currently not available for 100.4 but it is quite easy to create the functionality by creating a custom interaction listener e.g.

import com.esri.arcgisruntime.geometry.Envelope;
import com.esri.arcgisruntime.geometry.Point;
import com.esri.arcgisruntime.mapping.ArcGISMap;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.Viewpoint;
import com.esri.arcgisruntime.mapping.view.Graphic;
import com.esri.arcgisruntime.mapping.view.GraphicsOverlay;
import com.esri.arcgisruntime.mapping.view.MapView;
import com.esri.arcgisruntime.mapping.view.MapView.DefaultInteractionListener;
import com.esri.arcgisruntime.symbology.SimpleFillSymbol;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.geometry.Point2D;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

public class ZoomBoxTest extends Application {
  private MapView mapView = new MapView();

  @Override
  public void start(Stage stage) throws Exception {
    Platform.setImplicitExit(true);

    BorderPane borderPane = new BorderPane();

    javafx.scene.Scene fxScene = new javafx.scene.Scene(borderPane);

    stage.setWidth(500);
    stage.setHeight(500);
    stage.setScene(fxScene);
    stage.show();

    stage.show();

    ArcGISMap map = new ArcGISMap(Basemap.createDarkGrayCanvasVector());
    mapView.setMap(map);

    borderPane.setCenter(mapView);
    mapView.setInteractionListener(new ZoomBoxInteraction(mapView));
  }

  @Override
  public void stop() {
    if (mapView != null) {
      mapView.dispose();
    }
  }

  public static void main(String[] args) {
    Application.launch(args);
  }

  /**
   * Creates an interaction listener that allows you to zoom in by defining an envelope by dragging the mouse.
   */
  class ZoomBoxInteraction extends DefaultInteractionListener {

    private GraphicsOverlay graphicsOverlay = new GraphicsOverlay();
    private Graphic boxGraphic;
    private Envelope box;
    Point firstPoint;
    Point lastPoint;

    ZoomBoxInteraction(MapView mapView) {
      super(mapView);
    }

    @Override
    public void onMousePressed(MouseEvent e) {
      mapView.getGraphicsOverlays().add(graphicsOverlay);
      boxGraphic = new Graphic();
      graphicsOverlay.getGraphics().add(boxGraphic);
      boxGraphic.setSymbol(new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, 0x88FF0000, null));
      firstPoint = mapView.screenToLocation(new Point2D(e.getX(), e.getY()));
      lastPoint = firstPoint;
      box = new Envelope(firstPoint, lastPoint);
      boxGraphic.setGeometry(box);
    }

    @Override
    public void onMouseReleased(MouseEvent e) {
      mapView.setViewpoint(new Viewpoint(box));
      mapView.getGraphicsOverlays().remove(graphicsOverlay);
      graphicsOverlay.getGraphics().clear();
      firstPoint = null;
      lastPoint = null;
      box = null;
      boxGraphic = null;
    }

    @Override
    public void onMouseDragged(MouseEvent e) {
      lastPoint = mapView.screenToLocation(new Point2D(e.getX(), e.getY()));
      box = new Envelope(firstPoint, lastPoint);
      boxGraphic.setGeometry(box);
    }
  }
}

What is mapview.setEnableTouchZoom(true).

This enables/disables zooming in/out by using a pinching touch gesture on touch enabled devices.
