I have a JSON with the below structure:

[
    {
        "timestamp": "2019-07-12 00:29:37",
        "OutletTemperatureCV": "31.5",
        "ChocolateMixingTemperatureCV": "30.399999",
        "WaterCoolingTemperatureCV": "13.899",
        "WaterMixingTemperatureCV": "31.5"
    }
]

The Json file is named as temperer. I am trying to parse this json array to get values values.

JSONArray array1=new JSONArray(temperer);
for (int n = 0; n < array1.length(); n++) {
    JSONObject jsonObject = array1.getJSONObject(n); 
    String time= jsonObject.getString("timestamp");
    String outletTemp= jsonObject.getString("OutletTemperatureCV");
    String outletTemp= jsonObject.getString("ChocolateMixingTemperatureCV");
    String outletTemp= jsonObject.getString("WaterCoolingTemperatureCV");
    String outletTemp= jsonObject.getString("WaterMixingTemperatureCV");
}

But when I try this code, I get the below error..

org.json.JSONException: JSONArray initial value should be a string or collection or array.

I saw another post in SO with a similar prob, but this example uses a named JSON array. (Parsing JSON Array within JSON Object)

How can I get over this error for an unnamed JSON array? Any solutions will be hugely helpful :(

  • What is the datatype of variable temperer? It should be of String type containing the json string. Commented Jul 17, 2019 at 8:26

  • Hi, the temperer json is dynamically obtained from an API call. Structure will be the same as given here, which is an unnamed Json array if I am not wrong? Commented Jul 17, 2019 at 8:43
  • can you add some more code, including temper type @Krishna Commented Jul 17, 2019 at 8:47
  • Turns out my temperer is a String with a named array. I am not sure how to iterate over the named array now. Will post it as a separate question to avoid more confusion. Thanks for trying to help me out Commented Jul 17, 2019 at 11:36
