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

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) {
        }
    })

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...

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");
