Here is some code that works for me:

public class  MainActivity extends AppCompatActivity {
public static String storeLang;

@Override
protected void onCreate(Bundle savedInstanceState) {

    SharedPreferences shp = PreferenceManager.getDefaultSharedPreferences(this);
    storeLang = shp.getString(getString(R.string.key_lang), "");

    // Create a new Locale object
    Locale locale = new Locale(storeLang);

    // Create a new configuration object
    Configuration config = new Configuration();
    // Set the locale of the new configuration
    config.locale = locale;
    // Update the configuration of the Accplication context
    getResources().updateConfiguration(
            config,
            getResources().getDisplayMetrics()
    );

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

}
