How to set text from YouTube subscriber count JSON file?

Question

I'm developing an app where I want to show total subscribers of a YouTube channel using JSON, AsyncTask, TextView. I don't know how to parse a JSON data. Please help me!

My problem has been solved HERE

The JSON API link HERE

https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCtjgLjaefEi4kcWBl5rpoZg&fields=items/statistics/subscriberCount&key=AIzaSyBU_oWEIULi3-n96vWKETYCMsldYDAlz2M

The JSON file itself

JSON.java class

public class JSON extends AsyncTask<String, String, JSONObject> {

    String link = "https://www.googleapis.com/youtube/v3/channels?part=statistics&id=" +
            "UCtjgLjaefEi4kcWBl5rpoZg&fields=items/statistics/subscriberCount&key=AIzaSyBU_oWEIULi3-n96vWKETYCMsldYDAlz2M";

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

    }

    @Override
    protected JSONObject doInBackground(String... args) {

        return null;
    }

    @Override
    protected void onPostExecute(JSONObject json) {

    }
}

My main activity

TextView tv;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = (TextView) findViewById(R.id.textView);
}

I desperately need some help, please don't avoid this question!
