Long task on Broadcastreceiver, error: android.os.Networkonmainthreadexception

Question

When I perform a task (which usually requires a AsyncTask) in the BroadcastReceiver, he accuses me of error:

erro: android.os.NetworkOnMainThreadException

I saw that it is not a good practice a AsyncTask within a BroadcastReceiver.

Then the most appropriate would be a Service ? Or it’s not about the mistake !?

public class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.i("lgg", "onReceive " + new Date());

        StringBuilder content = new StringBuilder();
        try {
            URL url = new URL("site.com");
            URLConnection urlConnection = url.openConnection();
            urlConnection.setConnectTimeout(5000);
            urlConnection.setReadTimeout(5000);

            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                content.append(line + "\n");
            }
            bufferedReader.close();

        } catch (Exception e) {
            e.printStackTrace();
            Log.i("lgg", "erro: " + e);
        }

        Log.i("lgg", "recebido: " + content);
    }
