Android Jason parsing without Array name

Android Jason parsing without Array Name

A few good sights to learn simple jason parsing before learning this:

1. http://www.androidhive.info/2012/01/android-json-parsing-tutorial/

2.    http://www.vogella.com/articles/AndroidJSON/article.html

Below is an example of json without array name :    

........

  [ { "cnt":1,
    "text":"American",
    "pk":7
  },
  {
    "cnt":2,
    "text":"Celebrities",
    "pk":3
  },
  {
    "cnt":1,
    "text":"Female",
    "pk":2
  },
  {
    "cnt":1,
    "text":"Language",    "pk":8
  },
  {
    "cnt":1,
    "text":"Male",    "pk":1
  },
  {
    "cnt":1,
    "text":"Region",    "pk":9
  }]




You don't need to call json.getJSONArray()like this  

// Getting Array of Contacts 

    contacts = json.getJSONArray("contacts");

 because the JSON you're working with already a Jsan array. So, don't construct an instance of JSONObject; Only you need to call

Hopeflly this example will help you in parsing jason array without  name.
