Reading a Json Array in android

Question

I'm trying to read a JSON array. Here is my code.

        JSONArray jArray = new JSONArray(jsonString);          System.out.println("*****JARRAY*****"+jArray.length());         for(int i=0;i<jArray.length();i++){                   JSONObject json_data = jArray.getJSONObject(i);                 Log.i("log_tag","_id"+json_data.getInt("account")+                         ", mall_name"+json_data.getString("name")+                         ", location"+json_data.getString("number")+                         ", telephone"+json_data.getString("url")+                         ",----"+json_data.getString("balance")+                         ",----"+json_data.getString("credit")+                         ",----"+json_data.getString("displayName")                 );          } 

And my sample JSON files syntax is as follows,

{     "list": [         {             "account": 1,             "name": "card",             "number": "xxxxx xxxx xxxx 2002",             "url": "http://www.google.com",             "balance": 1.0,             "credit": 1.0,             "displayName": "hsbc bank"          },         {             "account": 2,             "name": "card2",             "number": "xxxxx xxxx xxxx 3003",             "url": "http://www.google.com",             "balance": 2.0,             "credit": 2.0,             "displayName": "nsb bank"          }      ],     "count": 2 } 

It has a curly brace in front. When i try to execute this code block it gives an error saying

A JSONArray text must start with '[' at character 1 of....

Has anyone encountered a problem like this? Any help would be greatly appreciated. Please show me a sample code block if can. Thanks in advance.

A JSON Object starts with a { and ends with a } while a JSON Array starts with a [ and ends with a ].

In your case, change your code to have a JSONObject instead.

JSONObject json = new JSONObject(jsonString); JSONArray jArray = json.getJSONArray("list");  System.out.println("*****JARRAY*****" + jArray.length());  for(int i=0; i<jArray.length(); i++){     JSONObject json_data = jArray.getJSONObject(i);      Log.i("log_tag", "_id" + json_data.getInt("account") +         ", mall_name" + json_data.getString("name") +         ", location" + json_data.getString("number") +         ", telephone" + json_data.getString("url") +         ",----" + json_data.getString("balance") +         ",----" + json_data.getString("credit") +         ",----" + json_data.getString("displayName")     ); }
