Hello everyone, I am new on Arcgis map. So my question is basic but i get some problem.
I am trying this sample application, this is my code :
-------------------------------------------------------------------------------------------------
package wilmar.helloworldarcgis;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import com.esri.android.map.FeatureLayer;
import com.esri.android.map.MapView;
import com.esri.core.geodatabase.GeodatabaseFeatureServiceTable;
import com.esri.core.geodatabase.GeodatabaseFeatureServiceTable.Status;
import com.esri.core.map.CallbackListener;
import com.esri.core.renderer.ClassBreaksRenderer;
public class MainActivity extends Activity {
MapView mMapView;
GeodatabaseFeatureServiceTable table;
FeatureLayer feature_layer;
ClassBreaksRenderer wind_renderer;
static int LAYER_ID = 0;
View calloutView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMapView = (MapView) findViewById(R.id.map);
mMapView.setEsriLogoVisible(true);
mMapView.enableWrapAround(true);
// Inflate the view for the callouts
calloutView = View.inflate(this, R.xml.callout, null);
String url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapSe...";
// Create the GeodatabaseFeatureServiceTable from service url and layer
// id
table = new GeodatabaseFeatureServiceTable(url, LAYER_ID);
// Initializing the GeodatabaseFeatureServiceTable asynchronously
table.initialize(new CallbackListener<GeodatabaseFeatureServiceTable.Status>() {
@Override
public void onCallback(Status objs) {
if (objs == Status.INITIALIZED) {
// Creating a feature table
feature_layer = new FeatureLayer(table);
// Adding feature layer to the map
mMapView.addLayer(feature_layer);
}
}
@Override
public void onError(Throwable e) {
// Get the error using getInitializationError() method
Toast.makeText(getApplicationContext(), "Feature Layer not available", Toast.LENGTH_LONG).show();
}
});
}
/*
* Called when the activity is destroyed
*/
@Override
protected void onDestroy() {
super.onDestroy();
}
/*
* Called when the activity pauses
*/
@Override
protected void onPause() {
super.onPause();
mMapView.pause();
}
/*
* Called when the activity resumes
*/
@Override
protected void onResume() {
super.onResume();
mMapView.unpause();
}
}

On layout xml i put just some map.
I run this code and i got the result is :
When i using this url : http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapSe...
It just show basic map, without layer on map.
But when i use this url : http://tmservices1.esri.com/arcgis/rest/services/LiveFeeds/NOAA_METAR_current_wind_speed_direction/M...
It show layer on map. (Like arrow pointer)
My question is....
did i wrong on my code..?
if i wrong can you suggest something so the map will show the layer using first url.
and
I relize something, the first url is Geometry Type: esriGeometryPolyline
and the second is Geometry Type: esriGeometryPoint
Is there have different way if i want to implement it on map..?
Thanks For Your help.
