i folllow question luck: how parse json array inside json array in android

if suggest, m doing wrong appreciate. or let me know, can more information json

update give precious time answering stupid question. answers correct , can accept 1 answer. big all

here:

jsonobject jo = new jsonobject(); jsonarray ja = new jsonarray(); // populate array jo.put("arrayname", jsonobj);

because parsing jsonobj jsonarray no need create new jsonarray , jsonobject extract jsonobj. remove above 3 lines.

banner jsonarray inside jsonobject contained jsonobj jsonarray, as:

   jsonobject jsonobject=jsonobj.optjsonobject(0);     jsonarray subarray = jsonobject.getjsonarray("banner");     // code key `jsonobject`    string strcode=jsonobject.optstring("code");     // images urls `subarray`     for(int index=0;index<subarray.length();index++){       jsonobject imgjsonobject=subarray.optjsonobject(index);       // image urls       string strimgurl=imgjsonobject.optstring("image");       }

also, if jsonobj jsonarray contains multiple jsonobject's use for-loop iterate it.
