Я пытаюсь получить текущую дату и время от Google. со следующим кодом
private class LongOperation extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
try {
HttpClient httpclient = new DefaultHttpClient();
//for Android 9
httpclient.getConnectionManager().getSchemeRegistry().register(
new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)
);
HttpResponse response = httpclient.execute(new HttpGet("https://google.com/"));
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
String currentDateTime = response.getFirstHeader("Date").toString().replace("Date: ", "");
SimpleDateFormat formatter = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss zz");
// String temp = "Thu Dec 17 15:37:43 GMT+05:30 2015";
try {
date = formatter.parse(currentDateTime);
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat sd = new SimpleDateFormat("dd/MM/yyyyHH:mm:ss");
GoogleDate = sd.format(date);
System.out.println("Google Date :" + GoogleDate);
} else {
//Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (IOException e) {
Log.d("Response", e.getMessage());
}
return GoogleDate;
}
@Override
protected void onPostExecute(String serverDate) {
Toast.makeText(MainActivity.this, "Time is "+ serverDate, Toast.LENGTH_SHORT).show();
}
}
Он отлично работает в сборке и выпуске отладки, но когда я установил значение minify в файле Gradle, приложение вылетает и показывает следующую ошибку.

Пожалуйста, помогите мне. Кто-нибудь может сказать мне скрипт Proguard, который нужно добавить?
Я также приложил вывод сборки. 
Ваша добрая помощь будет высоко оценена.
