Force Android DateUtils.getRelativeDateTimeString() to ignore the device locale?

This is working for me up to Android 7

  void forceLocale(Locale locale) {
    Configuration conf = getBaseContext().getResources().getConfiguration();
    updateConfiguration(conf, locale);
    getBaseContext().getResources().updateConfiguration(conf, getResources().getDisplayMetrics());

    Configuration systemConf = Resources.getSystem().getConfiguration();
    updateConfiguration(systemConf, locale);
    Resources.getSystem().updateConfiguration(conf, getResources().getDisplayMetrics());

    Locale.setDefault(locale);
  }

  void updateConfiguration(Configuration conf, Locale locale) {
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
      conf.setLocale(locale);
    }else {
      //noinspection deprecation
      conf.locale = locale;
    }
  }

According to the source code of the DateUtils class it uses both Resource.getSystem() and Locale.getDefault() method for formatting date and time. You can change the default Locale using Locale.setDefault() method but I don't think it's possible to change the return value of the Resource.getSystem() method. You can try to change the default locale to Locale.US but it seems to me that results will be even worse in this case.
