and sample json response : (sorry json language persian , titles won't shown because of not utf-8) :

{ "dbversion":"4" ,  "groups":[ {     "id"    : 1,     "title" : "کامپیوتر",     "bg"    : "1.png" }, {     "id"    : 2,     "title" : "شیمی",     "bg"    : "2.png" }, {     "id"    : 3,     "title" : "برق Ùˆ الکترونیک",     "bg"    : "3.png" }, {     "id"    : 4,     "title" : "Ùیزیک",     "bg"    : "4.png" }, {     "id"    : 5,     "title" : "ریاضی",     "bg"    : "5.png" }, {     "id"    : 6,     "title" : "مکانیک Ùˆ هواÙضا",     "bg"    : "6.png" }, {     "id"    : 7,     "title" : "زیست",     "bg"    : "7.png" } ] }
