Tiles loading errors with OSMDroid 3.0.7

[GoogleCodeExporter]

What steps will reproduce the problem?
When migrating a very simple app from OSMDroid 3.0.5 to OSMDroid 3.0.7,I get 
numerous errors when loading tiles (from TileSourceFactory.MAPNIK). 
Here is a typical stack trace:

Error downloading tile: /12/2027/1424
java.lang.NullPointerException
at 
org.osmdroid.tileprovider.modules.MapTileFilesystemProvider$TileLoader.loadTile(
MapTileFilesystemProvider.java:153)

What version of the product are you using? On what operating system?
OSMDroid 3.0.7 on AVD, Android 2.1.

I have the same problem.

OSMDRoid 3.0.7 (3.0.6 the same problem), Android 2.3.6

Note that these errors don't appear on an AVD with Android 2.3.3. But some 
(few) tiles remain unloaded. 

Here is the whole code: 

public class NavigationActivity extends Activity {

    @Override public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        
        MapView map = (MapView) findViewById(R.id.map);
        map.setTileSource(TileSourceFactory.MAPNIK);
        map.setBuiltInZoomControls(true);
        map.setMultiTouchControls(true);
        MapController mapController = map.getController();
        mapController.setZoom(16);
    int lat = 48131174;
    int lon = -1637256;
    mapController.setCenter(new GeoPoint(lat, lon));
    }
}

and the main.xml layout: 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <org.osmdroid.views.MapView android:id="@+id/map"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:layout_weight="1" />
</LinearLayout>

This error:

Error downloading tile: /12/2027/1424
java.lang.NullPointerException

was likely fixed in issue 325.

Are you getting an actual crash or just an exception being logged into Logcat?

I don't have a crash, I just have: 
- exceptions in Logcat
- and tiles that remain missing (greyed) in spite of all attempts to load them: 
zooming in/out, or moving the map back and forth, or exiting/restarting the 
app. 

When I come back to OSMDroid 3.0.5, all tiles immediately loads without any 
problem (same time, same kind of Internet access, same map provider). 

Note that I use the OSMDroid 3.0.7 jar published, without any patch. 
Maybe something wrong or missing in my code (not very complicated - see above)?

I had this problem too, but I change to 
osmdroid-android-3.0.8-20120208.220818-1.jar
and it seems to work fine both online and offline, but why virsion 8 is not 
listed in this site

I just updated my app from Osmdroid 3.0.5 to osmdroid-android-3.0.8.jar (which 
is now published here). 
Initially, I got the same java.lang.NullPointerException errors. 
I completely cleaned the SD card (containing the cache of tiles), and now 
everything is fine. 

One additional remark: upgrading my app from Osmdroid 3.0.5 to 3.0.8 was a 
simple replacement of the jar: no code change needed. This was not the case to 
upgrade from  3.0.5 to 3.0.7 => good job, guys!

It sounds like this issue has been resolved, so I will close it. Glad it's 
working for you now!
