Parsing JSON object in Android Studio, Object not updating in try block -


i working on college project , trying parse timetable information api appears this:

"1474239600000" : {     "coursecode" : "case4",         "modulecodes" : [ "careersservice" ],     "moduledescription" : "careers svs. slots in year 4s",         "starttime" : 1474286400000,          "endtime" : 1474290000000,       "locations" : [ "gla.xg21", "gla.q119" ],             "type" : "seminar"        }

i running parsing code in asynctask of android activity. here code have done this:

protected lecture doinbackground(string... urls) {     lecture lec = new lecture();  try{          bufferedreader in = new bufferedreader(         new filereader("json.txt"));           string inputline;               string content = "";      while ((inputline = in.readline()) != null) {             content = content + inputline;             system.out.println(inputline);             //log.d("input:",inputline);         }       jsonobject obj = new jsonobject(content);     string coursecode = obj.getstring("coursecode");      string moduledescription = obj.getstring("moduledescription");          string type = obj.getstring("type");     lec = new lecture(coursecode,"test",moduledescription,type);         }catch(exception e){             log.e("json parser:","catch error");             e.printstacktrace();         }         return lec;     }

when return lecture object lec, not showing values assigned in try block default values set lecture.

i appreciate possible,

thanks, ryan.

your json malformed. change json following structure code should work:

{     "coursecode" : "case4",         "modulecodes" : [ "careersservice" ],     "moduledescription" : "careers svs. slots in year 4s",         "starttime" : 1474286400000,          "endtime" : 1474290000000,       "locations" : [ "gla.xg21", "gla.q119" ],             "type" : "seminar"    }

a json key can't root element of json document, in case "1474239600000". because of receiving exception because jsonobject can't created.
