How to access nested arrays in a JSON object (Android) -


the structure of json is,

"posts":[     //post 1.             {         "images":{             "small":{                 "url": "http://..."                 "width": 64             },             "large":{                 "url": "http://..."                 "width": 128             }         },          "caption":"..."     },      {         //post 2         "images":{             "small":{                 "url": "http://..."                 "width": 64             },             "large":{                 "url": "http://..."                 "width": 128             }         },          "caption":"..."       }  ]

i want get, posts -> images -> large -> url each post in form of string.

here's i've done:

jsonarray jsonarray = jsonobject.getjsonarray("posts");  (int = 0; < jsonarray.length(); i++) {     jsonobject jsonobject = jsonarray.getjsonobject(i);     jsonarray innerarray1 = jsonobject.getjsonarray("images");     jsonarray innerarray2 = innerarray1.getjsonarray(0);    //gets "large"     jsonarray innerarray3 = innerarray2.getjsonarray(1);    //gets "url"     string finalstring = innerarray3.tostring(); }

i expected value of "url" in finalstring, except ends being empty.

what doing wrong?

"images", "small", "large" jsonobjects(notice curly braces), not jsonarrays(square brackets) , need extract them such.

jsonarray jsonarray = jsonobject.getjsonarray("posts");  (int = 0; < jsonarray.length(); i++) {     jsonobject jsonobject = jsonarray.getjsonobject(i);     jsonobject innerobject1 = jsonobject.getjsonobject("images");     jsonobject innerobject2 = innerobject1.getjsonobject("large");    //gets "large"     string finalstring = innerobject2.getstring("url"); }
