Invalid SpatialReference

Question

Hello, I'm just starting to work with android sdk I do everything by example helloworld XML [HTML] [/HTML] Java [HTML]public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); map = (MapView)findViewById(R.id.map); // Add dynamic layer to MapView basemap = new ArcGISTiledMapServiceLayer("http://myserver:8000/ArcGIS/rest/services/MyServices/MapServer"); map.addLayer(basemap); } [/HTML] Log:10-29 11:15:50.520: E/ArcGIS(700): url =http://myserver:8000/ArcGIS/rest/services/MyServices/MapServer 10-29 11:15:50.520: E/ArcGIS(700): java.lang.RuntimeException: Invalid SpatialReference. 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.core.geometry.SpatialReference.nativeGetWKID(Native Method) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.core.geometry.SpatialReference.create(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.core.geometry.SpatialReference.fromJson(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.core.internal.c.g.a(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.core.internal.a.a.n.b(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.android.map.ags.ArcGISTiledMapServiceLayer.initLayer(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at com.esri.android.map.ags.ArcGISTiledMapServiceLayer$1.run(Unknown Source) 10-29 11:15:50.520: E/ArcGIS(700): at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:442) 10-29 11:15:50.520: E/ArcGIS(700): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) 10-29 11:15:50.520: E/ArcGIS(700): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 10-29 11:15:50.520: E/ArcGIS(700): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) 10-29 11:15:50.520: E/ArcGIS(700): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) 10-29 11:15:50.520: E/ArcGIS(700): at java.lang.Thread.run(Thread.java:856) My service is cached and running where and how to to specify parameter SpatialReference [ATTACH=CONFIG]18795[/ATTACH] Spatial.jpg Display XY Data - ArcMap.PNG screen-shot-types.png

this might be because your data is not in WKID 4326.  It's in a modified Spatial Reference.  That's ok.  You can define that in your code.  
I can't see it all in the screen shot so you'll have to finish it.  Just copy/paste your Spatial Reference from your REST endpoint into your codeblock..SpatialReference wgs84 = SpatialReference.create("GEOGCS['GCS_WGS_1984',DATUM[.........]]);

You'll have to finish the Spatial Reference text.  I can't see it all, and I don't feel like typing it.  You get my point 😉

Hope this helps.

Take out the   initExtent parameter from your layout xml file. You are using you own map service which is in a different spatial reference than the service provided in the HelloWorld sample. If you still want to set the initial extent in your layout xml file, then adjust the coordinates to the spatial reference of your map service.

please can show an sample
//import android.R.string;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;

import com.esri.android.map.MapView;
import com.esri.android.map.ags.ArcGISTiledMapServiceLayer;
import com.esri.core.geometry.Envelope;
import com.esri.core.geometry.SpatialReference;

public class CityActivity extends Activity {
 MapView mv = null;
 SpatialReference wgs84 = SpatialReference.create(4326);
 Context content; 
 @Override
 public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
 Envelope envelope=new Envelope(-25256, -17337, 28560, 13883);
 mv=new MapView(content, wgs84, envelope);
 ArcGISTiledMapServiceLayer Tservice=new ArcGISTiledMapServiceLayer("http://myserver:8000/ArcGIS/rest/services/myservices/MapServer");
 //mv.setExtent(envelope);
 mv.addLayer(Tservice);
 // setContentView(mv);
 
 }
 @Override
does not start((
Thanks
