What steps will reproduce the problem?
1. Trying to load previously download maptiles from /sdcard/osmdroid/ folder
2. Trying to use my app offline
What is the expected output? What do you see instead?
The tiles should be loaded offline in the absence of internet connectivity, but
when there is no internet connectivity no map is loading.
What version of the product are you using? On what operating system?
osmdroid-android-4.1.jar
osmbonuspack_v4.4.jar
eclipse android sdk
Please provide any additional information below.
I have create a simple OSM Map application for offline viewing and navigation.
While creating the app, I followed the following tutorials:

The application is working fine when Internet connectivity is working. But,
when there is not internet connection, the app should load tiles from the
/sdcard/osmdroid/ folder which is not happening. No tiles are getting loaded
when I am offline.
My main intention is to allow the users to download tiles of different cities
from the internet and use them later when they do not have internet
connectivity.
The activity which I have created:
public class MainActivity extends Activity {
double myCurrentLatitude;
double myCurrentLongitude;
// The MapView variable:
MapView mapView;
List<Overlay> mapOverlays;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// get current location
GPSTracker tracker = new GPSTracker(this);
if (tracker.canGetLocation() == false) {
tracker.showSettingsAlert();
} else {
myCurrentLatitude = tracker.getLatitude();
myCurrentLongitude = tracker.getLongitude();
}
mapView = (MapView) findViewById(R.id.mapview);
mapView.setClickable(true);
// mapView.setBuiltInZoomControls(true);
// for only pinch zoom
mapView.setMultiTouchControls(true);
mapView.setTileSource(TileSourceFactory.MAPQUESTOSM);
mapView.getController().setZoom(15);
mapView.getController().setCenter(
new GeoPoint(myCurrentLatitude, myCurrentLongitude));
// mapView.getController().setCenter(
// new GeoPoint(18.9750, 72.8258));
mapOverlays = mapView.getOverlays();
showMyCurrentLocation();
showFoodJoint("1",22.5850, 88.3750, "Test food", "Maniktala");
showFoodJoint("2",22.576600900000000000, 88.367032500000050000, "Test food 2", "College Street");
// =====For showing restaurant location on

}
// =====For showing my current location on map======================//
public void showMyCurrentLocation() {
Drawable myLocationDrawable = this.getResources().getDrawable(
R.drawable.pin_for_my_location);
MapItemizedOverlay itemizedoverlayForMyLocation = new MapItemizedOverlay(
myLocationDrawable, this);
itemizedoverlayForMyLocation.setEnabled(true);
itemizedoverlayForMyLocation.setEnabled(true);
// setting pin to my current position on the map
GeoPoint myCurrentPoint = new GeoPoint(myCurrentLatitude,
myCurrentLongitude);
// GeoPoint myCurrentPoint = new GeoPoint(18.9750,
// 72.8258);
OverlayItem overlayitem = new OverlayItem("Id","Hello", "You are here",
myCurrentPoint);
itemizedoverlayForMyLocation.addOverlay(overlayitem);
mapOverlays.add(itemizedoverlayForMyLocation);
mapView.getController().setZoom(15);
mapView.getController().setCenter(myCurrentPoint);
}
// =====For showing my current location on map======================//

public void showFoodJoint(String foodJointId,double foodJointLat, double foodJointLon, String foodJointName, String foodJointDescription)
{

GeoPoint myPoint1 = new GeoPoint(foodJointLat, foodJointLon);
OverlayItem overlayitem2 = new OverlayItem(foodJointId,foodJointName,foodJointDescription, myPoint1);
itemizedoverlayForRestaurant.addOverlay(overlayitem2);
mapOverlays.add(itemizedoverlayForRestaurant);
}
// =====For showing restaurant location======================//
// For routing

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void makeAToast(String str) {
Toast toast = Toast.makeText(this, str, Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
Where am I going wrong?
