Android Studio – JSONObject cannot be converted to String

I saw this questions a bunch of times here in Stack, but had no luck. The thing is, I’m using this API for validate my CNPJ field, if I have a connection, the response would be the field "nome" and populate my textview field.

So far so good, the JSON is valid (already passed in jsonformatter) but I can’t the object through JSONArray and when I manage to find it by JSONObject it tells me that can’t be converted to String.

 valide.setOnClickListener(view1 -> {
        //String PJ = cnpj.getText().toString();
        String PJ = "06990590000123";
        String url = "https://www.receitaws.com.br/v1/cnpj/" + PJ;
        jsonParse(url);
    });


private void jsonParse(String url) {
    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

        String json;
        @Override
        public void onResponse(JSONObject response) {
            try {
                json = response.getJSONObject("nome").toString();

                razao.append(json);
                razao.setText(json);

            } catch (JSONException e) {
                e.printStackTrace();
                Toast.makeText(getActivity(), "Invalid ! ", Toast.LENGTH_SHORT).show();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError erro) {
            erro.printStackTrace();
        }
    });

    mQueue.add(request); //Volley.newRequestQueue
}

JSON

{ "atividade_principal": [ { "text": "Portais, provedores de conteúdo e outros serviços de informação na internet", "code": "63.19-4-00" } ],

"data_situacao": "01/09/2004",

at org.json.JSON.typeMismatch(JSON.java:101)

    In your JSON the nome is of type String. So rather than getJSONObject use getString method from JSONObject class. So your code should be like below:

    private void jsonParse(String url) {
    JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

        String json;
        @Override
        public void onResponse(JSONObject response) {
            try {
                json = response.getString("nome"); // Here is the change

                razao.append(json);
                razao.setText(json);

            } catch (JSONException e) {
                e.printStackTrace();
                Toast.makeText(getActivity(), "Invalid ! ", Toast.LENGTH_SHORT).show();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError erro) {
            erro.printStackTrace();
        }
    });

    mQueue.add(request); //Volley.newRequestQueue
}

    Try this:
    First construct JsonObject and then get the string value of the key.

    JSONObject jsonObject = new JSONObject(json);
String valueIWanted = jsonObject.getString("nome"))
