如何在android pre Nougat (< api 24)上获取设备区域设置？

import android.content.Context;
import android.content.res.Configuration;
import android.content.res.Resources;
import java.util.Locale;

public class DeviceUtils {
    public static Locale getDeviceLocale(Context context) {
        Resources resources = context.getResources();
        Configuration config = resources.getConfiguration();
        return config.locale;
    }
}
