com.esri.arcgisruntime.ArcGISRuntimeException: Invalid JSON

Question

I am new in the arcgis runtime. I am trying to develop an android application.

Steps that i follwed

• Created an account in arcgis.com .
• Then i created one Feature Layer (hosted) from the shape files zip .
• Then i share this to everyone.
• I copied the url given at the below. url is . Please see the output for the url.
• Then i try to implemet means to show this in the map on my android application And trying to do some feature-layer-query.Refference is in the GITHUB
• I am trying to replace the service_url to my url. I am doing the search operation and getting the result from the online then trying to zoom that extent. But is noe even showing my map too.
• Now i am getting problem. it showing the error in

  05-10 16:31:23.516 20030-20030/com.esri.arcgisruntime.samples.featurelayerquery E/Feature layer query: Feature search failed for: kulathoor. Error=com.esri.arcgisruntime.ArcGISRuntimeException: Invalid JSON

Please see the below image for ref enter image description here

My code try

@Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 // inflate MapView from layout
 mMapView = (MapView) findViewById(R.id.mapView);
 // create a map with the topographic basemap
 final ArcGISMap map = new ArcGISMap(Basemap.createTopographic());
 // set the map to be displayed in the mapview
 mMapView.setMap(map);
 // create feature layer with its service feature table
 // create the service feature table
 //mServiceFeatureTable = new ServiceFeatureTable(getResources().getString(R.string.sample_service_url));
 mServiceFeatureTable = new ServiceFeatureTable("https://services7.arcgis.com/7FyZZrSIYfiWYztL/arcgis/rest/services/MyGisFileLayerTest/MapServer");
 // create the feature layer using the service feature table
 mFeaturelayer = new FeatureLayer(mServiceFeatureTable);
 mFeaturelayer.setOpacity(1.0f);
 //override the renderer
 SimpleLineSymbol lineSymbol= new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, Color.RED, 1);
 SimpleFillSymbol fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, Color.YELLOW, lineSymbol);
 mFeaturelayer.setRenderer(new SimpleRenderer(fillSymbol));
 // add the layer to the map
 map.getOperationalLayers().add(mFeaturelayer);
 // zoom to a view point of the USA
 mMapView.setViewpointCenterAsync(new Point(-11000000, 5000000, SpatialReferences.getWebMercator()), 100000000);
 }

Can you find out where i am doing mistake . Why the may is not shwing in my app. Below is the screen shot of my application.enter image description here

Answer 1

Update your FeatureServer url to the layer id, https://services7.arcgis.com/7FyZZrSIYfiWYztL/ArcGIS/rest/services/MyGisFileTest/FeatureServer/0. Here is some updated code:

 ArcGISMap map = new ArcGISMap(Basemap.Type.STREETS_VECTOR, 8.498151, 76.929790, 10);
 // set the map to be displayed in this view
 mMapView.setMap(map);
 ServiceFeatureTable serviceFeatureTable = new ServiceFeatureTable("https://services7.arcgis.com/7FyZZrSIYfiWYztL/ArcGIS/rest/services/MyGisFileTest/FeatureServer/0");
 FeatureLayer featureLayer = new FeatureLayer(serviceFeatureTable);
 featureLayer.setOpacity(1.0f);
 SimpleLineSymbol lineSymbol= new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, Color.BLACK, 1);
 SimpleFillSymbol fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, Color.YELLOW, lineSymbol);
 featureLayer.setRenderer(new SimpleRenderer(fillSymbol));
 map.getOperationalLayers().add(featureLayer);
