How can I access to the SharedPreferences inside doInBackground AsyncTask?

Question

I have a problem when I want to access to my SharedPreferences inside doInBackground. How can I do this?

Really thanks!

private class postData extends AsyncTask<String, Void, String> {
  @Override
  protected String doInBackground(String... params) {

    // I need to access here to my SharedPreferences //

  }
}

You can access SharedPreferences in background threads (the same way you do on a main thread) as they are stored persistently. — Edison, Mar 08 '13 at 22:12

The solution was easier than I thought.

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", "");
  }
}

IDK why would this work, the getApplicationContext() is a method of the Context class and the AsyncTask does not extend it – viplezer Nov 22 '13 at 12:12

This answer is not correct, getApplicationContext() does not work here. – Loolooii Feb 26 '14 at 14:47

The context bit is wrong, but you can pull some working bits out of this – justinraczak May 30 '16 at 00:12
