you need make jsonarray thumbnails. reference see example

try 

public list<newsobj> constructjson(string jsonin){ arraylist<newsobj> newslist = new arraylist<>(); try{     //add more levels extract json     jsonobject jsonobject1 = new jsonobject(jsonin);     string responsedata = jsonobject1.getstring("responsedata");     log.d("receivejsonobjectlevel1",responsedata);      jsonobject jsonobject2 = new jsonobject(responsedata);     string feed = jsonobject2.getstring("feed");     log.d("receivejsonobjectlevel2",feed);      jsonobject jsonobject3 = new jsonobject(feed);     string entries = jsonobject3.getstring("entries");     log.d("receivejsonobjectlevel3", entries);      jsonarray jsonarray1 = new jsonarray(entries);     for(int i=0; i<jsonarray1.length();i++){         jsonobject mediagroups = jsonarray1.getjsonobject(i);         string mediaitems = mediagroups.getstring("mediagroups");         string title = mediagroups.getstring("title");         string url = mediagroups.getstring("link");         string description = mediagroups.getstring("contentsnippet");         string publisheddate = mediagroups.getstring("publisheddate");        //                main information news article          //for further thumbnail sizes?         jsonarray jsonarray2 = new jsonarray(mediaitems);         for(int j=0;j<jsonarray2.length();j++){             jsonobject contents = jsonarray2.getjsonobject(j);             string contentitems = contents.getstring("contents");             log.d("receivejsonobjectarray2",contentitems);              jsonarray jsonarray3 = new jsonarray(contentitems);             for(int k=0;k<jsonarray3.length();k++){                 jsonobject items = jsonarray3.getjsonobject(k);                 //too specific                 string imgurl = items.getstring("url");                 //log.d("receivejsonobjectarray3",imgurl);                  string thumbnails = items.getstring("thumbnails");                  jsonarray jsonarray4 = new jsonarray(thumbnails);                 for(int l=0;l<jsonarray4.length();l++){                 jsonobject thumbnails1 = jsonarray4.getjsonobject(l);                  string height = items.getstring("height");                 string width = items.getstring("width");                 string thumburl = items.getstring("url");                  }                 newsobj aobj = new newsobj(title, imgurl,url, publisheddate);                 newslist.add(aobj);             }         }     }  }catch (jsonexception e){     e.printstacktrace();     log.d("receivejsonerror",e.tostring()); } return newslist; }
