Android : java.lang.String cannot be converted to JSONArray

Question

I am getting json Exception while trying to parse a string to jsonArray. I am using loopj method for json Parsing. This is the error :

java.lang.String cannot be converted to JSONArray

And this is the json I am trying to parse :

[{\"displayName\":\"Thiruvananthapuram\",\"desc\":\"Partly cloudy\",\"cloudCover\":\"5\",\"dateTime\":\"Sunday October 02\",\"humidity\":\"85\",\"visibility\":\"10\",\"tempCelcius\":\"29\",\"iconClass\":\"PartlyCloudy-s\"}]

My code is

    AsyncHttpClient client = new AsyncHttpClient();
   client.get("url", new AsyncHttpResponseHandler() {
    @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

        try {
        String jsonStr = new String(responseBody, "UTF-8");
        Log.e("Tag ", "on Result " + jsonStr);
        JSONArray jsonarray = new JSONArray(jsonStr);
                Log.e("Tag ", "jsonArr length " + jsonarray.length());
        }
        catch (UnsupportedEncodingException e)
        {
          e.printStackTrace();
        }
        catch (Exception e)
        {
          e.printStackTrace();
            }
        }
        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
        }
    })

i tried jsonStr = jsonStr.replaceAll("[]",""); but no user @dariush f — Binil Surendran

you replaced brackets ([]) , do this : jsonStr = jsonStr.replaceAll("\",""); — Dariush Fathi

First you have to get jsonObject using jsonString using line below

JSONObject jsnobject = new JSONObject(jsonStr);

Then you can iterate through the jsonObject to get jsonArray object.

JSONArray jsonArray = jsnobject.getJSONArray("your json array key");

json array key means , there is no key for jsonArray, In the result i have only one array@ascii_walker

for jsonFile like this: { "orgList": [ { "orgInfo": { "id": 1, "orgName": "Organization X" }, {},{}...} Key for jsonArray is : orgList

here the reult is JsonArray not JsonObject [{\"displayName\":\"Thiruvananthapuram\",\"desc\":\"Partly cloudy\",\"cloudCover\":\"5\",\"dateTime\":\"Sunday October 02\",\"humidity\":\"85\",\"visibility\":\"10\",\"tempCelcius\":\"29\",\"iconClass\":\"PartlyCloudy-s\"}] @ascii_walker

You can replace "\" with "" to make it look like normal json then you can parse it by iterating through key value pair of json array

you have to replace the "\" to "" then convert into the JsonArray:-

example:-

 String jsonStr = new String(responseBody, "UTF-8");

jsonStr = jsonStr.replace("\","");

// now convert it into JsonArray
  JSONArray jsonarray = new JSONArray(jsonStr);

hope this help you...
