android - Route calculation failed and simulating re-routing -

i using skobbler sample android sdk (downloaded here) write navigation application , works perfect if run application android studio when install application using generated apk, fails on route calculation , in logs is:

also, there way simluate re-routing when using navigation in sknavigationtype.simulation mode? tried changing current user location explicitly inside oncurrentpositionupdate(skposition currentposition) method this, isn't working:

@override public void oncurrentpositionupdate(skposition currentposition) {     iteration++;      this.currentposition = currentposition;     if (mapview != null) {          if(iteration >= 5) {             toast.maketext(mapactivity.this, "changed location", toast.length_long).show();             this.currentposition = new skposition();             this.currentposition.setcoordinate(new skcoordinate(101.618133, 3.025863));         }          mapview.reportnewgpsposition(this.currentposition);     } } 

for simulating re-routing, have use blockroad method sknavigationmanager. please check doc here: http://developer.skobbler.ro/docs/android/com/skobbler/ngx/navigation/sknavigationmanager.html#blockroad%28double%29
