Using ArcGIS andorid 100x API I'm trying to determine if points returned onLocationChanged are within a queried feature. When I use the GeometryEngine.within() method I'm getting runtime errors stating that "geometry1 and geometry2 must have equivalent spatial references." Adding a breakpoint to my code I see that my Point (i.e., geometry 1) has spatial reference SR: 4326, but the spatial reference (feature.getGeometry()) associated with the feature returned from my queryFeatureAsync (i.e., geometry 2) is null. Assuming this is the source of the problem, how can I get my feature to have the correct spatial reference?
Code snippet:
// get the MapView's LocationDisplay
this.mLocationDisplay = this.mMapView.getLocationDisplay();
this.mLocationDisplay.addLocationChangedListener(new LocationDisplay.LocationChangedListener() {
@Override
public void onLocationChanged(LocationDisplay.LocationChangedEvent locationChangedEvent) {
final LocationDataSource.Location l = locationChangedEvent.getLocation();
// segments == layer containing geometries of interest
if (MainActivity.this.segments != null) {
final FeatureTable featureTable = MainActivity.this.segments.getFeatureTable();
featureTable.addDoneLoadingListener(new Runnable() {
@Override
public void run() {
featureTable.removeDoneLoadingListener(null);
QueryParameters queryParameters = new QueryParameters();
queryParameters.setWhereClause(String.format("feature_identifier='%1$s'", "myFeature"));
final ListenableFuture<FeatureQueryResult> listenableFuture = featureTable.queryFeaturesAsync(queryParameters);
listenableFuture.addDoneListener(new Runnable() {
@Override
public void run() {
try {
FeatureQueryResult featureQueryResult = listenableFuture.get();
if (featureQueryResult.iterator().hasNext()) {
try {
Iterator<Feature> iterator = featureQueryResult.iterator(); // create an Iterator
Feature feature;
while (iterator.hasNext()) { // cycle through results
feature = iterator.next();
if (l.getPosition() != null) {
//****next line: geometry1 and geometry2 must have equivalent spatial references *****
if (GeometryEngine.within(l.getPosition(), feature.getGeometry())) {
Log.d(TAG, "inside feature");
} else {
Log.d(TAG, "outside feature");
}
}
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
});
}
});
}
}
});
