problem in json parsing in android app

Question

in my app when i hit an url i am getting a return data as an json array. it is as follows

{"Status":[{ "img_path": "http://xxxxxxxxxxxxxx.com/images/thumb140/1316145577.jpg", 
             "img_path": "http://xxxxxxxxxxxxxx.com/images/thumb140/1316146270.jpg", 
             "img_path": "http://xxxxxxxxxxxxxx.com/images/thumb140/1316146473.jpg", 
             "img_path": "http://xxxxxxxxxxxxxx.com/images/thumb140/1316147003.jpg" } ]}

From the above result i am trying to parse out the urls and i am trying to store it in an array list. Following is my code

 try{
        JSONArray get_post_status = json.getJSONArray("Status");
        for (int i = 0; i < get_post_status.length(); i++) {
        JSONObject e = get_post_status.getJSONObject(i);
        if(e.equals("img_path"))
        {
            Get_post_image_array.add(e.getString("img_path"));
        }
        }

But in my arraylist i am getting only the last url from the result. How to get all the urls in the arraylist.

Pls help me.......

Did you know that you can use example.com as an example host name? example.com is a reserved domain name, as specified in RFC 2606. — Magnus Hoff

The returned JSON is invalid.

Shortening the data, looking only at the structure:

{
    "Status":
        [
            {
                "img_path": "a", 
                "img_path": "b", 
                "img_path": "c", 
                "img_path": "d"
            }
        ]
}

We can see that the array (enclosed in []) only contains one element; the object enclosed by {}. This object has several instances of the same key, "img_path". This is not valid. Your parser apparently ends up with keeping only the last instance of it.

The JSON ought to look more like this:

{
    "Status":
        [
            "a", 
            "b", 
            "c", 
            "d"
        ]
}

Your JSON is invalid.

{"Status": [ {"img_path": "blah, blah"}, {"img_path": "blah2, blah3"}]}

is what you want. Essentially, you were setting the same key in an object over and over, not creating a list of objects.
