Adding OpenStreetMap to HelloWorld in 10.2.2

Hello, I want to add an OpenStreetMap tile service layer to the Esri Android HelloWorld app. I'm following the OpenStreetMap documentation here. Find the relevant code below:

public class HelloWorld extends Activity {
  MapView mMapView;

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mMapView = (MapView)findViewById(R.id.map);
    String[] tileServerURL = {"http://b.tile.cloudmade.com/{KEY}/1/256"};
    OpenStreetMapLayer tileLayer = new OpenStreetMapLayer(tileServerURL, 1, 16, "CloudMade", true);
    tileLayer.setKey("myKey"); 
 
    mMapView.addLayer(tileLayer); //when this line is commented out the app runs just fine

LogCat gives an EsriServiceException and the app closes when I include the code above in the app. I'm probably missing something minor? Can someone clue me in?

Thanks! Patty

The reason why the app runs when you comment out the mMapView.addLayer(tileLayer) is that the MapView's basemap is set in XML. Open up the /res/layout/main.xml file and comment out all the mapoptions parameters. Your XML should look like this:

<!-- MapView layout, including basemap layer, initial center point, and zoom level --> 
<com.esri.android.map.MapView 
  android:id="@+id/map" 
  android:layout_width="fill_parent" 
  android:layout_height="fill_parent" />

I can confirm that the url you provide resolves to http://b.tile.cloudmade.com/myKey/1/256 at runtime.

I responded to your GIS Stackexchange question as well.
