How to catch "com.esri.arcgisruntime.internal.io.handler.request.BaseRequest getInvalidApiKeyException?"

Question

When an API key is bad resulting in an application failing to download a base map, the runtime outputs this message to stdout, "com.esri.arcgisruntime.internal.io.handler.request.BaseRequest getInvalidApiKeyException?" How to we catch this exception so that we can inform the user that the API key is bad? Right now, it just produces an error with a INFO log statement which a user will not see. We want to catch it and display an alert box in the GUI when the key is bad.

You can identify this state in code by adding load listener to the map which is trying to use your bad API key.

I've done this very crudely in the code below:

// authentication with an API key or named user is required to access basemaps and other location services
      ArcGISRuntimeEnvironment.setApiKey("bad API key");
      // create a map with the standard imagery basemap style
      ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_IMAGERY);

map.addDoneLoadingListener(()-> {
        System.out.println("load status" + map.getLoadStatus());
        if (map.getLoadStatus() == LoadStatus.FAILED_TO_LOAD) {
          System.out.println("error " + map.getLoadError().getCause());
        }
      });

// create a map view and set the map to it
      mapView = new MapView();
      mapView.setMap(map);

We don't throw a specific error for this condition (IOException), but the cause comes up as you spotted in the console window.

Does this help?
