I use osmdroid for my mapping needs in Android. Until a few days ago, I could see the map, and everything was fine, but now every time the activity of the map starts, I get an empty map and the following trace:

this is what my onCreate code looks like:
super.onCreate(savedInstanceState);
this.me = this;
this.mMapView = new MapView(this, 256);
this.mMapView.setTileSource(TileSourceFactory.MAPNIK);
this.mMapView.setClickable(true);
this.mMapView.setBuiltInZoomControls(true);
this.mMapView.getController().setZoom(10);
this.mMapView.getController().setCenter(new GeoPoint(39.461078, 2.856445));
IntentFilter filter = new IntentFilter();
filter.addAction(UpdateRequester.ACTION);
this.registerReceiver(this.mUpdateReciever, filter);
setContentView(this.mMapView);
}
and the manifest file has the following permissions:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-feature android:name="android.hardware.location.network" />
<uses-feature android:name="android.hardware.location.gps"
android:required="true"/>
<uses-feature android:name="android.hardware.wifi" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
Has anyone come across this, or do you have any idea what the problem is?
The strange thing is that it worked fine, and nothing has changed.
This problem occurs using an emulator.
