You just need to get the JSONArray and iterate the JSONObject inside the Array using a loop though in your case its only one JSONObject but you may have more   JSONArray mArray          try               mArray   new JSONArray responseString                for  int i   0  i  lt  mArray length    i                          JSONObject mJsonObject   mArray getJSONObject i                       Log d  OutPut   mJsonObject getString  NeededString                                 catch  JSONException e                e printStackTrace
