  protected  integer doinbackground(void... params) {          arraylist = new arraylist<hashmap<string, string>>();          jsonarray = jsonfunctions.getjsonfromurl(murl2);                   if ( internetpresent )                 {                     db = new databasehelper(getapplicationcontext());                     (int = 0; < jsonarray.length(); i++) {                         hashmap<string, string> map = new hashmap<string, string>();                         jsonobject = jsonarray.getjsonobject(i);                         // retrive json objects                         map.put("id", jsonobject.getstring("id"));                         map.put("title", jsonobject.getstring("title"));                         map.put("type1", jsonobject.getstring("type1"));                         map.put("type", jsonobject.getstring("type"));                         map.put("matn", jsonobject.getstring("matn"));                         map.put("date", jsonobject.getstring("date"));                         map.put("address", jsonobject.getstring("address"));                          arraylist.add(map);                         long id = db.insertnewentity(jsonobject.getint("id"),jsonobject.getstring("title"),                                 jsonobject.getstring("type"),jsonobject.getstring("matn"),jsonobject.getstring("date"),hid                                 ,jsonobject.getstring("type1"),jsonobject.getstring("_new"),jsonobject.getstring("address"));                      }

try 1 of libs below.

nostra’s universal image loader – https://github.com/nostra13/android-universal-image-loader

picasso – http://square.github.io/picasso/

both great caching images offline.
