Legend

Are there any samples on using a legend with a service that is hosted from my ArcGIS Server.  I keep getting errors when I try to usethe get legend method on the LayerInfos.

According to documentation, to have layer legend info available for your ArcGISDynamicMapServiceLayer you must call retrieveLegendInfo() method on this layer instance. Also it must be called in separate thread. The following seems to be good approach:

mapView.setOnStatusChangedListener(new OnStatusChangedListener() {

                    @Override

                    public void onStatusChanged(Object o, STATUS status) {

                        if (status == STATUS.LAYER_LOADED) {

                            if (o instanceof ArcGISDynamicMapServiceLayer) {

                                //retrieving legend info

                                new AsyncTask<Void, Void, Void>() {

                                    @Override

                                    protected Void doInBackground(Void... voids) {

                                        dynamicLayer.retrieveLegendInfo();

                                        return null;

                                    }

                                }.execute();

                            }

                        }

                    }

                });
