Answer 1

use this

new Thread(new Runnable() {
  @Override
  public void run() {
    try {
      URL myUrl = new URL(url);
      URLConnection urlConnection = myUrl.openConnection();
      urlConnection.connect();
      int file_size = urlConnection.getContentLength();
      Log.i("sasa", "file_size = " + file_size);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}).start();

That will definitely work for you,

new AsyncTask<Void, Void, Void>() {

            @Override
            protected Void doInBackground(Void... voids) {
                try {
                    URL url = new URL("http://YOUR_URL_HERE");
                    int fileLength = url.openConnection().getContentLength();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return null;
            }         
        }
