java - Make simply HTTP request and receive the content

Question

I have found a working code for makeing simply HTTP requests here, from How can I make a simple HTTP request in MainActivity.java? (Android Studio) and I am going to post it below (with some changes, if I am not wrong it is now necessery to use try{} catch{}). But I would like to ask how I can receive the content? I work with the code in the following way:

GetUrlContentTask req = new GetUrlContentTask();
req.execute("http://192.168.1.10/?pin=OFF1");
textView3.setText(req.doInBackground("http://192.168.1.10/?pin=OFF1")); 

GetUrlContentTask

private class GetUrlContentTask extends AsyncTask<String, Integer, String> {
    protected String doInBackground(String... urls) {
        // String content1 = "";
        try {
            URL url = new URL(urls[0]);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setDoOutput(true);
            connection.connect();


            BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String content = "", line;
            while ((line = rd.readLine()) != null) {
                content += line + "
";
            }
            // content1 = content;
        }
        catch (Exception e) {
            e.printStackTrace();
        }

        // return content1; - returns "", wrong
        return "aaa";
        //does not work    return content;
    }

    protected void onProgressUpdate(Integer... progress) {
    }

    protected void onPostExecute(String result) {
        // this is executed on the main thread after the process is over
        // update your UI here    
    }
}

Answer 1

Add this to your onPostExecute(String result) call

    protected void onPostExecute(String result) {
        // this is executed on the main thread after the process is over
        // update your UI here    
        setMyData(result);
    }

And then fill your textfield or whatever other data you need to update.

    private void setMyData(String result){
        textView3.setText(result); 
    }
