SetLocationAcquiringSymbol problem (10.2.2)

Question

Hello,

I set a special symbol for the option of SetLocationAcquiringSymbol.
I was positive that this symbol will appear when i have no GPS signal and/or when i turn the GPS off. However i see no difference in the symbol from when i got GPS signal or not.

How can i know when i am in the state of acquiring GPS? Isn't it supposed to be everytime i have no signal (The gps icon is blinking)?
OR is there a bug there?

Thanks,
Team Igal

Ilona,

I moved my LocationDisplayManager intialization code to the onStatusChangedListener, as you are doing in your code. I was not able to get my hands on an S3 running 4.1.1, but I tested on a Moto X running 4.4.2, an S3 running 4.3, and a Motorola Razr HD running 4.1.2

On all of these devices, the functionality worked as expected. Sitting in my office with the location set to "device only", I get my custom location acquiring symbol. As I then walk outside, my symbol gets changed to my custom default symbol. I can get many location updates, and it never gets changed back to the pre-packaged blue/white symbols. I cannot seem to reproduce your issue.

Can you try it on another device? I really doubt that the device is the problem, but I just want to eliminate another factor. It seems we have almost identical code, so I can't imagine what else the problem may be.

Best regards,
Michael

EDIT: got ahold of an S3 running 4.1.2, still worked as expected on there as well.

unfortunately i cant provide code samples, but i am using Samsung Galaxy S3 with android version 4.1.1.

I have the same code as you wrote - with one slight difference - i initialized the LocationDisplayManager property in the OnStatusChanged event of the MapView OnStatusChangedListener - so that i will make sure that the mapView is initialized before i set the LocationDisplayManager.

Ilona,

May I ask what device you're using? And could you provide a code snippet where you're setting up the LocationDisplayManager?

I performed my testing on a Moto X running Android 4.4. In case it may provide any assistance, I've pasted below my code snippet for my Activity, where I set up the LocationDisplayManager
public class HelloWorld extends Activity {

MapView mMapView;
        LocationDisplayManager ldm;

/** Called when the activity is first created. */
@Override
 public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            mMapView = new MapView(this);
            mMapView.addLayer(new ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer")); 
            setContentView(mMapView);
  
     try {
         ldm = mMapView.getLocationDisplayManager();
         PictureMarkerSymbol check = new PictureMarkerSymbol(this, getResources().getDrawable(R.drawable.checkmark));
         PictureMarkerSymbol gps2 = new PictureMarkerSymbol(this, getResources().getDrawable(R.drawable.gps2));
         ldm.setLocationAcquiringSymbol(gps2);
         ldm.setDefaultSymbol(check);
         ldm.setCourseSymbol(check);
         ldm.start();
     } catch(Exception e) {
      e.printStackTrace();
     }
 }

@Override
 protected void onPause() {
  super.onPause();
  mMapView.pause();
        }

@Override
 protected void onResume() {
  super.onResume(); 
  mMapView.unpause();
 } 
}

Best regards,
Michael
