解决方案比我想象的要容易。

private class postData extends AsyncTask<String, Void, String> {
  @Override
  protected String doInBackground(String... params) {
    SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext() );    
    String userName = sharedPrefs.getString("auth_username", "");
    String userPass = sharedPrefs.getString("auth_password", "");
  }
}
