<pre>24864-24864/com.example.fortuinelife D/TAG: SponcerIDException: org.json.JSONException: Value <?xml of type java.lang.String cannot be converted to JSONObject
2022-01-13 15:03:18.204 24864-24864/com.example.fortuinelife D/TAG: SponcerID_EX_Response: <?xml version="1.0" encoding="utf-8"?>

What I have tried:

<pre>I am trying to set value for sponsorID to the textview but but I'm not able to parse response to line etSponsor_name.setText(strSponsorId);   this is my code

Java

<pre>TextView sponsorName,etSponsor_name;
String strSponsorId = "";
sponsorId.setOnFocusChangeListener(new View.OnFocusChangeListener() {

        @Override
        public void onFocusChange(View view, boolean b) {
            strSponsorId = sponsorId.getText().toString();
            String url = Config.URL + "webapi/fortuneapi.asmx/CheckSponcer?SponcerID=" + strSponsorId;
            Log.d("TAG", url);
            StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                        Log.d("TAG", "SponcerID: " + response);


                        try {

                            JSONObject jsonObject = new JSONObject(response);
                            strSponsorId = jsonObject.optString("SponsorID","");
                            Log.i("TAG", "parseData: " + strSponsorId);
                            etSponsor_name.setText(strSponsorId);


                        } catch (Exception e) {
                            Log.d("TAG", "SponcerIDException: " + e);
                        }
                        Log.d("TAG", "SponcerID_EX_Response: " + response);

                    }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("TAG", "onErrorResponse_of_sponcerID: " + error.getMessage());


                }
            });

The error seems to suggest that the response is XML, not JSON.

you are receiving XML as response instead of JSON that is why following line is giving exception.

JSONObject jsonObject = new JSONObject(response);

You need to change these two lines

JSONObject jsonObject = new JSONObject(response);
strSponsorId = jsonObject.optString("SponsorID","");

To

JSONObject jsonObject = XML.toJSONObject(response);
strSponsorId = jsonObject.optString("string","");

Hopefully this should work
