map.getOperationalLayers().add(mapImageLayer);
mMapView.setViewpoint(new Viewpoint(23.056295, 46.195800, 29000000));
GraphicsOverlay graphicsOverlay = addGraphicsOverlay(mMapView);
mMapView.setMap(map);
// Add a listener that is invoked when layer loading has completed.
mapImageLayer.addDoneLoadingListener(() -> {
    if (mapImageLayer.getLoadStatus() == LoadStatus.LOADED) {
        ArcGISMapServiceInfo mapServiceInfo = mapImageLayer.getMapServiceInfo();
    }
    else if(mapImageLayer.getLoadStatus()==LoadStatus.FAILED_TO_LOAD)

Hi,
Can you print your load error for the layer and see the exception and its cause/message ? 

mapImageLayer.getLoadError() 

Thanks
