java - FileNotFoundException when trying to find nearby Places with Maps API -

i've been following tutorial in order create app shows nearby places using google maps , places apis. specifically, i'm trying view nearby restaurants or takeaways. is, app displays map fragment, no places show markers.

i have tried increasing radius value, , changing type of ones listed here: https://developers.google.com/places/documentation/supported_types, same filenotfoundexception error. can see what's gone wrong?

here's logcat.

thanks, i'd appreciate help.

edit: exception gone, markers still aren't showing on map.

looks url builder broken. have:

stringbuilder sb = new stringbuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?");         sb.append("?types=meal_takeaway");         sb.append("location="+mlatitude+", "+mlongitude);         sb.append("&radius=10000");         sb.append("&sensor=true");         sb.append("&key=[my api key]"); 

this means have two ? between json , types, , no & between types=meal_takeaway , location. fix so:

stringbuilder sb = new stringbuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?");         sb.append("types=meal_takeaway");         sb.append("&location="+mlatitude+","+mlongitude);         sb.append("&radius=10000");         sb.append("&sensor=true");         sb.append("&key=[my api key]"); 

(note: changes in first 2 sb.append() invocations -- removed space)

fwiw, easier in long run use volley or similar json requests, rather downloading url , parsing separately.
