org.json.JSONArray cannot be converted to JSONObject

Question

I am new to JSON and I am getting the follwoing Exception:

org.json.JSONArray cannot be converted to JSONObject in the first line of try se

Answer 1

This

JSONObject json = new JSONObject(strResponse);
// your strResponse is a json array 

should be

JSONArray jsonarray = new JSONArray(strResponse);

[ represents json array node

{ represents json object node

for(int i=0; i < jsonarray.length(); i++) {
    JSONObject jsonobject = jsonarray.getJSONObject(i);
    String id       = jsonobject.getString("id");
    String title    = jsonobject.getString("title");
    String company  = jsonobject.getString("company");
    String category = jsonobject.getString("category");
}

Answer 2

You should probably initialize json as a JSONArray:

JSONObject json = new JSONObject(strResponse);

Should then be:

JSONArray json = new JSONArray(strResponse);

However, that wouldn't work with the following two operations:

JSONArray name = json.names(); //.names() doesn't exist in JSONArray
JSONArray  internships = json.toJSONArray(name); // Is instead to be seen as

That would be alright if you just alter your loop to get the JSONObject from json instead (thus removing the dependency towards .names():

JSONObject e = json.getJSONObject(i);

Edit: Full code

try {   
    JSONArray internships = new JSONArray(strResponse);

    //Loop the Array
    for(int i=0;i < internships.length();i++) {     
        Log.e("Message","loop");
        HashMap<String, String> map = new HashMap<String, String>();
        JSONObject e = internships.getJSONObject(i);
        map.put("id",  String.valueOf("id"));
        map.put("title", "Title :" + e.getString("title"));
        map.put("company", "Company : " +  e.getString("company"));
        map.put("category", "Category : " +  e.getString("category"));
        mylist.add(map);
    } 
} catch(JSONException e) {
    Log.e("log_tag", "Error parsing data "+e.toString());
}

Answer 3

try this one , Your first block is json array so get first json array

JSONArray jsonarray = new JSONArray(strResponse);

    for(int i=0;i < jsonarray .length();i++) {
    JSONObject jsonobj = new JSONObject(i);
            map.put("id",   jsonobj .getString("id"));
            map.put("title",  jsonobj .getString("title"));
            map.put("company",  jsonobj .getString("company"));
            map.put("category",  jsonobj .getString("category"));
            mylist.add(map);

         }

Answer 4

if that really is the json you are receiving you should replace the entire this:

JSONObject json = new JSONObject(strResponse);

//Get the element that holds the internship ( JSONArray )
JSONArray name = json.names();
JSONArray  internships = json.toJSONArray(name);

with

JSONArray  internships = json.toJSONArray(strResponse);

Answer 5

Issue:

 JSONObject json = new JSONObject(strResponse);

here, strResponse may be in format of JSONArray due to which you are getting this exception while converting it into JSONObject.
