You are looking for AsyncTask. AysncTask has doInBackground() method to do your time consuming task. All other methods run on main thread. Something like this

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

            @Override
            protected void onPreExecute() {
                // before executing background task. Like showing a progress dialog
            }

            @Override
            protected String doInBackground(Void... params) {
                // Do background task here
            }

            @Override
            protected void onPostExecute(String msg) {
               // This will be executed when doInBackground() is finished.
               // "msg" is value returned by doInBackground()
            }
        }.execute(null, null, null);
