You can use Map<Object, Object> where value be collection of json Element you want. You can make custom deserilizator with lib like "gson".
You should try: JSONArray arr = new JSONArray(JSON_STRING);

Encoding Special characters in Android Json object

I am sending json object to server, My url having json object.Json object having special characters,how to encoding special characters in android, please help me.Thanks in advance.

Use UrlEncode.encode(yourstring, "UTF-8");

If I understood you, you want to send a json object using the url itself (that is, as a parameter). If security doesn't matter you (it will be visible), you could just encode using [Base64][1].
You should probably play with your json object to convert it to a byte[], called jsonbytes, for instance, then use Base64.encodeToString(jsonbytes, Base64.URL_SAFE) and sending this as a parameter.
Your server then should convert this Base64 encoded string into a json object, which tends to be straightforward if you're using PHP:
$jsonString = base64_decode($_GET['json']);
$json = json_decode($jsonString, TRUE);
This will give you an associative array in PHP. If you just want the json string, skip the last step.

Parsing xml node content in Android

I've managed to parse xml responses from a SOAP web service when I receive it in the following format:

However, I'm now receiving the string in the following format:

I literally have zero idea how to get at the session data, which is the data I would like.
