-

i have runtime error in logcat:

05-11 06:24:23.672: error/androidruntime(327): java.lang.runtimeexception:      unable create application net.osmand.activities.osmandapplication:     java.lang.illegalargumentexception: inputstream cannot null

...

after debugin found exception comme how??? in methode :

private baseosmandrender loadrenderer(string name, set<string> loadedrenderers) throws ioexception, saxexception {         inputstream = null;         if(externalrenderers.containskey(name)){             = new fileinputstream(externalrenderers.get(name));         } else if(internalrenderers.containskey(name)){             = osmandrenderingrulesparser.class.getresourceasstream(internalrenderers.get(name));         } else {             throw new illegalargumentexception("not found " + name); //$non-nls-1$         }         baseosmandrender b = new baseosmandrender();         b.init(is);         loadedrenderers.add(name);         list<baseosmandrender> dependencies = new arraylist<baseosmandrender>();         (string s : b.getdepends()) {             if (loadedrenderers.contains(s)) {

the "is" varible null

any please

if remember correctly, getresourceasstream returns null if cannot find resource. suspect that's cause of problem.
