I am getting the following String response from a server:

{"fid":"1272","uri":"http://someurl/services/file/1272"}

I need to convert it into a JSONArray. Any help?

By the way, I tried this and it does not work:

String response=getResponseFromServer();
JSONArray array = new JSONArray(response);

I get the error:

org.json.JSONException: Value {"fid":"1272","uri":"http://someurl/services/file/1272"} of type org.json.JSONObject cannot be converted to JSONArray

• jlordo: Have you tried anything? Are you using a JSON Library?
• fge: THis is a JSON OBJECT, not a JSON array
• marlenunez: It is a Java String, not a JSON object yet. He's doing Java, not Javascript.

Answer 1

If you're talking about using the JSON in java library, then since your input string is a JSON object, not a JSON array, you should first load it using JSONObject:

String response=getResponseFromServer();
JSONObject jsonObject = new JSONObject(response);

After that, you can use toJSONArray() to convert a JSONObject to JSONArray given an array of key strings:

String[] names = JSONObject.getNames(jsonObject);
JSONArray jsonArray = jsonObject.toJSONArray(new JSONArray(names));

• Inf Min: Ok. Thanks. JSONObject was new to me.
• keelar: No problem, you're welcome. That's what stackoverflow for :)

Answer 2

If you do a search right here on StackOverflow for Java String to JSONArray, you should get this answer: Converting from JSONArray to String then back again

JSONArray jArray;
String s = jArray.toString(); // basically what you have ;)
JSONArray newJArray = new JSONArray(s);

• Inf Min: The string I have is not in the format that the JSONArray constructor accepts.
• marlenunez: Ok, so see @keelar's answer in that case.
• Alexey Ivanov: The OP does not have JSONArray yet, and the JSON string in the question represents a JSONObject rather than a JSONArray.
