How to get a sharedPreferences key value before attachBaseContext called?

Question

My aim is overriding application language before it creates context and i'll use that context for calling other activities. Its possible via colling "recreate()" method on "onCreate" but i dont want to recreate activity to achive that goal. E.g

@Override
protected void attachBaseContext(Context newBase) {

    //null exception here
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

    String langKey = getString(R.string.pref_language_key);
    String langValue = sharedPreferences.getString(langKey, null);

    super.attachBaseContext(ConfigurationUtil.wrapLanguage(newBase, langValue));
}

If this is not possible, any ideas how to set application language that user have choosen from settings?

Answer 1

This worked for me:

SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(newBase);

please use newBase context and not your Activity context
