JSONarray Cannot Be Converted to JSONobject Error

JSONArray cannot be converted to JSONObject error

Change

JSONObject data = jsonObj.getJSONObject("data"); 

to

JSONArray data = jsonObj.getJSONArray("data");

As value of data is JsonArray not JSONObject.

And to Get individual Ids and Field Names, you should loop through this JSONArray, as follows:

for(int i=0; i<data.length(); i++)
{
     JSONObject obj=data.getJSONObject(i);
     String id = obj.getString("Id"); 
        String value = obj.getString("FieldName"); 
        Log.d("Item name: ", value);
}

Type JSONArray cannot be converted to JSONObject

This is the solution that i found, thanks for all guys ♥ ..

    private void jsonParse(){        String url="http://192.168.56.1:8095/rest/workouts/all";        JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET,url,null,                new Response.Listener<JSONArray>() {                    @Override                    public void onResponse(JSONArray jsonArray) {                        try {                                                        for(int i = 0; i < jsonArray.length(); i++) {

                                JSONObject jsonobject = jsonArray.getJSONObject(i);
                                String title = jsonobject.getString("title");                                String goal = jsonobject.getString("goal");
                                txtv.append(title + ", " + goal +"\n\n");                            }                        } catch (JSONException e) {                            e.printStackTrace();                        }                    }                },                new Response.ErrorListener() {                    @Override                    public void onErrorResponse(VolleyError error) {
                    }                });        mQueue.add(jsonArrayRequest);    }

items of type org.json.JSONArray cannot be converted to JSONObject

A JSONArray is an array of JSONObjects. Your items json node is an array, not an object. Replace

JSONObject snippet = jsonObject.getJSONObject("items");

with

JSONArray snippet = jsonObject.getJSONArray("items");

Then from your snippet array you can get the item object you need

JSONObject item = snippet.getJSONObject(0);

And from there

String t = item.getString("rating");

Getting ''org.json.JSONArray cannot be converted to JSONObject''

The prolem here is that your website response body object is a JSONArray

[
    {
        "status": "Success",
        "code": 1313,
        "msg": "Request completed successfully"
    }
]

So you get the exception because in the response handler you want a JSONObject and you can't cast a JSONArray to a JSONObject.

What your server (website) have to return to you is a root JSONObject and then in its node tree it could have JSONArray, but the root must be a JSONObject.

So fix your server side code so that it returns:

    {
        "status": "Success",
        "code": 1313,
        "msg": "Request completed successfully"
    }

org.json.jsonarray cannot be converted to jsonobject error

Relevant code to change - in doInBackground() of MainActivity.java:

JSONObject eventDetails = parent.getJSONObject("event");

to:

JSONArray eventDetails = parent.getJSONArray("event");
