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();
}
});
});
}
