Sending and Parsing JSON in Android

EDIT: Finally I found an answer to get array value without key value by using Iterator. I just got an idea from this link

I am just newbie to JSON Parsing, and I have no idea how to parse this kinda JSONArray. Can anyone give me a hint ?

{

 "pages": [
      "image1.jpg",
      "image2.jpg"
  ]
}

Doesn't JSON.parse work in android? that's an array **inside** an object by the way. — Asad Saeeduddin, Oct 13 '12 at 19:13

You have to understand the basic concepts of JSON .

{} talks about an instance (called JSONObject) [] talks about an array of somethings (called JSONArray in Android) "xxx":"yyy" talks about key & value

First, you may let the reply json string become an JSONObject, JSONObject replyJSON = new JSONObject(reply)

Then, get the JSONArray named 'pages' inside the replied JSONObject, JSONArray pagesArray = replyJSON.getJSONArray("pages")

Finally, get the value inside the JSONArray by the method getString, in your example, you may use pagesArray.getString(0) and pagesArray.getString(1)

Check out the documentation for more details: JSONArray

you may get the length of the JSONArray by using `.length()` and iterate though the JSONArray :) – code4j Oct 14 '12 at 06:36

Use new JSONObject(json); where json is the variable that stores your json string.

this isn't part of my answer, it is more of a remark on the quality of the question. – Asad Saeeduddin Oct 13 '12 at 19:29
my problem is that i don't have Key Value in `pages` Array. is there any way to get the whole data from `pages` Array with single line of code ? – myo htet aung Oct 13 '12 at 22:37

Use the JQuery function parseJSON:

var json = jQuery.parseJSON(string);

I believe, the OP is requesting how to parse JSON in Java on Android. Not in a browser and not using jQuery. – petey Oct 13 '12 at 19:17
