android - addressList size is 0 Google Maps -

i 'm trying use google maps. have code:

        public void onmapready(googlemap googlemap) {          mmap = googlemap;         mmap.getuisettings().setzoomcontrolsenabled(true);           list <address> addresslist = null;         if (location != null || !location.equals("")){             geocoder geocoder = new geocoder(this);             try {                 addresslist = geocoder.getfromlocationname(location, 1);               }catch (ioexception e){                 e.printstacktrace();             }             address address = addresslist.get(0);             latlng latlng = new latlng(address.getlatitude(), address.getlongitude());             mmap.addmarker(new markeroptions().position(latlng).title(location));             mmap.movecamera(cameraupdatefactory.newlatlngzoom(latlng, 15));         }     } 

but receive this: addresslist size 0. error "java.lang.indexoutofboundsexception: invalid index 0, size 0" location variable works fine. doing wrong? lot.

possibilities of getting 0 result

list getfromlocationname (string locationname, int maxresults) : returns : list of address objects. returns null or empty list if no matches found or there no backend service available.

and before calling method of geocoder address or results, check geocoder service can implemented using geocoder.ispresent()

if(geocoder.ispresent()){     //do stuff }else{    //cann't implement geocoder }
