android - How to retrieve ParseObject from Parse DataBrowser -

i have code: retrieve courses of student loged name in "namecurrentstudent" , stock courses in arraylist

parsequery<parseobject> query = parsequery.getquery("courses");     query = query.whereequalto("student", namecurrentstudent);     query.findinbackground(new findcallback<parseobject>() {          @override         public void done(list<parseobject> courselist, parseexception e)          {             if (e == null)              {                 courses.clear();                 (parseobject course : courselist)                  {                     courses.add(course.getstring("namecourse"));                 }             }              else              {                 log.d("post retrieval", "error: " + e.getmessage());             }         }     }); 

but when use debug skipps query.findinbackground(new findcallback() { know's why ?

parsequery<parseobject> queryp = parsequery.getquery("courses");     queryp.whereequalto("student", namestudent);     queryp.findinbackground(new findcallback<parseobject>() {         @override         public void done(list<parseobject> courseslist, parseexception e)          {             arraylist<string> courses = null;             if (e == null)              {                 courses = new arraylist<string>();                 (parseobject course : courseslist)                  {                     string coursename = course.getstring("coursesnameinparsecolumn");                            courses.add(coursename);                 }             }              else              {                 log.d("post retrieval", "error: " + e.getmessage());             }              populatecourseslist(courses);         }     });
