Hi Guys

I am new bee to ArcGis. I am developing ArcGis map in my Android app. may is displayed using one url in ArcGISTiledMapServiceLayer

this is my code fragment----

setContentView(R.layout.main);

  mMapView
= (MapView) findViewById(R.id.map);

mMapView.addLayer(new ArcGISTiledMapServiceLayer(

  "http://maps.ocparks.com/arcgis/rest/services/Imagery/2013_Imagery/MapServer"));

along with this url I am using some other urls for adding layers on map in ArcGISFeatureLayer. All is working good. now  I want to show current location of device on this Map. after going through several tutorials and documentations I came to know that for displaying location we must use

mMapView.addLayer(new ArcGISTiledMapServiceLayer(

  "

http://services.arcgisonline.com/ArcGIS/rest/services/

  World_Street_Map/MapServer

"));

so guys if there is any possible way to locate device location on ArcGis Imagery map.(not world_Street_map)

Your description of the problem is somewhat vague... do you mean you want to be able to use device GPS to locate yourself on map?

You need to use LocationDisplayManager - here is some code from my app

// In case you need it later, make it class variable

LocationDisplayManager lDisplayManager = null;

// ... inside onCreate(), after your .addlayers

mMapView.setOnStatusChangedListener(new OnStatusChangedListener() {

  
   @Override
   public void onStatusChanged(Object source, STATUS status) {

   if (source == mMapView && status == STATUS.INITIALIZED) {

 


  lDisplayManager = mMapView.getLocationDisplayManager();

   lDisplayManager.setAutoPanMode(LocationDisplayManager.AutoPanMode.LOCATION);

   lDisplayManager.setLocationListener(new LocationListener() {

   boolean locationChanged = false;

   // Zooms to the current location when first GPS fix arrives.
   @Override
   public void onLocationChanged(Location loc) {

   if (!locationChanged) {

   locationChanged = true;

   double locy = loc.getLatitude();

   double locx = loc.getLongitude();

  Point wgspoint = new Point(locx, locy);

  Point mapPoint = (Point) GeometryEngine

  .project(wgspoint,

  SpatialReference.create(4326),

   mMapView.getSpatialReference());

  Unit mapUnit = mMapView.getSpatialReference()

  .getUnit();

   double zoomWidth = Unit.convertUnits(

   5,

  Unit.create(LinearUnit.Code.MILE_US),

  mapUnit);

  Envelope zoomExtent = new Envelope(mapPoint,

  zoomWidth, zoomWidth);

   mMapView.setExtent(zoomExtent);

  }

  }

   @Override
   public void onProviderDisabled(String arg0) {

}

   @Override
   public void onProviderEnabled(String arg0) {

}

   @Override
   public void onStatusChanged(String arg0, int arg1,

  Bundle arg2) {

  }

  });  // Actionlistener

   lDisplayManager.start();

  }

  }

  }

   if (source == mMapView && status == STATUS.LAYER_LOADED) {

  }

  }

  }

});

There might be some extra } or { as I copy pasted it from the code and had to remove some special stuff related to our app.

HTH.

This code fragment only works with World_Street_Map server not with Imagery Map service
