get a Json value without string key - Java JSONObject

Question

It' easy to get a value from JSON when you have the string key, but what if you have situation like that:

{
  "images":["URL1"]
}

And array and no key inside? I use this code:

JSONArray imagesArr = propertiesjsonObject.getJSONArray("images");
for (int y=0; i<imagesArr.length(); y++)
{
  JSONObject imagesJsonObject = imagesArr.getJSONObject(y);
  String str_image_url = imagesJsonObject.get("HOW TO GET THE VALUES HERE?");
}

Propably it's ultra easy. Sorry to ask but I could not find proper example. PS. I use: import org.json.JSONArray; import org.json.JSONObject;

PS2: For now there is only one element in array, but in future I suppouse there might be more.

Try with this:

ArrayList<String> urls = new ArrayList<String>();
JSONArray imagesArr = propertiesjsonObject.getJSONArray("images");
for (int i = 0; i < imagesArr.length(); i++) {
    String str_image_url = imagesArr.getString(i);
    urls.add(str_image_url);
}

urls is an array with all the url you got

Hope this helps
