Error with generating parameters for downloading a map for use offline?

Hello, I am trying to download a map for offline use but am running into trouble with generating the parameters as per this error I get (I have included my code also):

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_offline);

    // inflate MapView from layout
    aMapView = (MapView) findViewById(R.id.mapView);
    map = new ArcGISMap(Basemap.Type.LIGHT_GRAY_CANVAS_VECTOR, 48.6596, -113.7870, 9);
    aMapView.setMap(map);
    // create a graphics overlay and symbol to mark the extent
    mGraphicsOverlay = new GraphicsOverlay();
    aMapView.getGraphicsOverlays().add(mGraphicsOverlay);

    mProgressLayout = (RelativeLayout) findViewById(R.id.progressLayout);
    final ProgressBar progressBar = (ProgressBar) findViewById(R.id.taskProgressBar);
    mProgressTextView = (TextView) findViewById(R.id.progressTextView);

    // get the callout that shows attributes
    //aCallout = aMapView.getCallout();
    // layer 0, facilities
    table0 = new ServiceFeatureTable(getResources().getString(R.string.layer0_url));
    final 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));
    final FeatureLayer featureLayer1 = new FeatureLayer(table1);
    map.getOperationalLayers().add(featureLayer1);

E/CRGdb: Error generating geodatabase parameters : com.esri.arcgisruntime.ArcGISRuntimeException: Invalid response

*******I have commented out portions of the code because it was returning this error each time and I wanted to know when it began (apparently it was after this line:

                            GenerateGeodatabaseParameters parameters = defaultParameters.get();

I realize this thread is ancient, but curious if anyone else has encountered this or has a solution? I am having the same issue when upgrading an app to 100.* The specific error message when running the .get() method is: "extent geometry and spatial reference must be non-null. The createDefaultGenerateGeodatabaseParametersAsync method doesn't take a spatial reference parameter and I am passing an extent into the the method, so the error message doesn't make sense in this context.
