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);

Hello, here is what my code in my onCreate method looks like now (I am following the code found on the Create an offline map guide page). I am using a button to begin the downloading process...I am confused because I do not find that the map is downloaded in the Downloads folder -- this code doesn't do anything but display my portal item: @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_offline);     // inflate MapView from layout     aMapView = (MapView) findViewById(R.id.mapView);     // get the portal url for ArcGIS Online     aPortal = new Portal(getResources().getString(R.string.portal_url));     // get the pre-defined portal id and portal url     aPortalItem = new PortalItem(aPortal, getResources().getString(R.string.webmap_glacier_national_park_id));     // create a map from a PortalItem     map = new ArcGISMap(aPortalItem);     // set the map to be displayed in this view     aMapView.setMap(map);     Log.d("MAP SET", "we have set our map!"); final Button startdownload = (Button) findViewById(R.id.startdownload); startdownload.setOnClickListener(v -> {    // create an offline map task         OfflineMapTask offlineMapTask = new OfflineMapTask(map);         //get all of the preplanned map areas in the web map         ListenableFuture<List<PreplannedMapArea>> mapAreasFuture = offlineMapTask.getPreplannedMapAreasAsync();         mapAreasFuture.addDoneListener(() -> {             try {                 // get the list of areas                 List<PreplannedMapArea> mapAreas = mapAreasFuture.get();                 // loop through the map areas                 for (PreplannedMapArea mapArea : mapAreas) {                     // load each map area                     mapArea.loadAsync();                     // create the job                     DownloadPreplannedOfflineMapJob downloadJob =                             offlineMapTask.downloadPreplannedOfflineMap(mapArea, Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString());                     //start the job                     downloadJob.start();                     // listen for job complete                     downloadJob.addJobDoneListener(() -> {                         // get the download result                         DownloadPreplannedOfflineMapResult downloadResult = downloadJob.getResult();                         // check for errors                         if (downloadResult.hasErrors()) {                             // code here to examine errors:                             Map<Layer, ArcGISRuntimeException> layerErrors = downloadResult.getLayerErrors();                             Map<FeatureTable, ArcGISRuntimeException> tableErrors = downloadResult.getTableErrors();                         } else {                             // no errors so use the map straight away                             map = downloadResult.getOfflineMap();                         }                     });                     mapArea.addDoneLoadingListener(() -> {                         // get the map area geometry so the is can used to display a graphic on the map                         Geometry areaGeometry = mapArea.getAreaOfInterest();                         // get the area title so it can be used in a UI component                         String areaTitle = mapArea.getPortalItem().getTitle();                         // UI code for showing map areas goes here:                     });                 }             } catch (InterruptedException e) {                 e.printStackTrace();             } catch (ExecutionException e) {                 e.printStackTrace();             }         });     }); } ...

It seems that all of the map objects that can be used to download a map are constructed using PortalItems in the Create an offline map guide. Is there a way to download a map to view offline using the Services pattern that is from a hosted feature service? Am I misreading the fact that you can allow feature service data to be downloaded, edited, and changes synchronized?  Also, when you view the map you have dowloaded offline, can you still enable popups to display the attributes of the features?  ...

Using the "Feature layer selection" sample code, how does the zoom-in work where when I select a feature, it zooms to it a certain odd way? Is this part of the Envelope? ... View more

I used the "Display device location" sample code but would like to make it so that whenever the Spinner is on "Stop", the map is re-centered on the initial extent. How can I do this? I have tried so far in the switch statement for the "Stop" case this below, however it does not render the layers or basemap when it "zooms back" and I am confused: if (!mLocationDisplay.isStarted())     mLocationDisplay.startAsync(); // create the location point Point centerPoint = new Point(48.6596, -113.7870, spatialReference); // set the map views's viewpoint centered on Waterloo and scaled aMapView.setViewpointCenterAsync(centerPoint, SCALE); aMapView.resume(); break; ...

Since I cannot save a layer file in a gdb, I have created two representations for two feature classes. I don't know what to do after "Convert Symbology to Representation". Now that I have created the representations, am I supposed to save the representations in the gdb along with their respective feature classes? How do I do this? I want to be able to publish the gdb as a hosted service on ArcGIS Online.  ... View more
