Android SDK Identify Sample?

[TylerWaring]

Greetings,

I am just getting started with the Android SDK and am working through some of the samples. I have gotten to the Identify sample and am a little bit confused about what I am working with. I subsequently have a couple of questions that would help me in my mission.

Am I working with the correct version of the Identify sample? I am working with the samples that I downloaded with ArcGIS for Android 2.0.0. The help files for this sample (http://help.arcgis.com/en/arcgismobile/10.0/apis/android/help/#/Identify_task_sample/01190000001w000...) describe a scenario that explores recent earthquakes. However, when I build and run my sample I get a map of the 50 states. Is the earthquake scenario the most up to date and if so where do I get a working copy of the code for the earthquake scenario?

When I run the Identify sample and click on a state, the popup spinner always lists a state that is different than the state I clicked on. For instance, If I click on Texas, I get New Mexico in my popup. When I click on the spinner dropdown, I get a list with Texas and all of the nearby states. Is this the intended result? Is there any way to make the identify point more accurate? I would like to have only one result returned when I click on a state.

Lastly when I swap out the sample map service with a parcel service of my own, I am unable to get any results in the popup. I am swaping out the URLs in the following locaitons:

In onCreate:

  
ArcGISTiledMapServiceLayer layer = new ArcGISTiledMapServiceLaye("http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Average_Household_Size/MapServer");
  
map.addLayer(layer);  

and in onPreExecute:

mIdentifyTask = new IdentifyTask("http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Average_Household_Size/MapServer");

My service supports the Identify as a supported opperation. Is there something I am missing?


Any hints, tips or nudges in the right direction will be greatly appreciated.

Best Regards,
Tyler

I have the same problem, can't seem to figure out the issue. The only differences between the sample and the service I am trying to identify is, my service is dynamic and the table is joined to another table. I was able to return results on a cached webservice. Not sure what would need to be changed in the sample to support a dynamic service.

When you are working with this sample there 3 changes necessary to make in order to make it work when you embed it in your application.
1. Change the URLS =  Which you have already done.

2. you have to set the parameter layers through an Array. You have to specify which layer/layers of the map service you are accessing  so change or alter this line
"params.setLayers(new int[]{0});" in the curly braces change specify the layer/layer the tool has to access. for ed params.setLayers(new int[]{0,1,2,3});

3. after accessing the layer you have to tell the tool on what bases or record it has to pull out. Usually it has to be a primary key like  record_id or a object id so chanege the field name in the following code according to a primary key in your mapservice.
in my case : if(curResult.getAttributes().containsKey("RECORDID")){  
    outputVal = curResult.getAttributes().get("RECORDID").toString();
With these three things done your code and tool should work fine.

do reply as whether this worked.

Hello,

  I m currently using the new ArcSDK 10.2.3. The problem is that I can not change the layer to identify. Whaterver I put, it will do the identify tasks in all the layers. Does the function setLayer function not any more?

Buen dia
Tengo problemas al reproducir el ejemplo del IdentifiTask
al hacer onclick sobre la pantalla no me muestra ninguna propiedad del mapa
la línea
mResult = mIdentifyTask.execute(mParams);

me devuelve mResult = null

pienso que debe ser por las escalas del dibujo, yo genero el archivo shape con ARCMAP pero no consigo que mis propiedades se puedan visualizar

Gracias,

Luis Bienvenido al Forum!
es el "archivo shape" = Esri 'shapefile'?
¿Está utilizando el SDK de Android?
aqui?:

Buen dia
Gracias por contester si yo utilizo el SDK
pero tengo la duda, para poder utilizar mapas propios es necesario de un MapServer?
