通知图标不会加载可绘制的到期区域设置

Question

我创建了一个简单的Android应用程序（https://github.com/soleimani/android-notification-locale）来通知文本，它有两个按钮，一个加载默认的区域设置文本和图标，另一个加载＆＃34; fa＆＃34;语言环境。图像，通知标题和通知文本都尊重区域设置，但通知图标来自默认区域设置（＆＃34; en＆＃34;）

    Button en = (Button) findViewById(R.id.buttonEN);
    en.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            conf.locale = new Locale("en");
            res.updateConfiguration(conf, dm);
            NotificationCompat.Builder overdueNotification = new NotificationCompat.Builder(getApplicationContext())
                    .setContentText(getText(R.string.notification_service_content_text))
                    .setSmallIcon(R.drawable.ic_stat);
            overdueNotification.setContentTitle(getText(R.string.notification_service_content_title));
            notificationManager.notify(1, overdueNotification.build());
            image.setImageResource(R.drawable.ic_stat);
            image.setImageResource(R.drawable.ic_launcher);

        }
    });

    Button fa = (Button) findViewById(R.id.buttonFA);
    fa.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            conf.locale = new Locale("fa");
            res.updateConfiguration(conf, dm);
            NotificationCompat.Builder overdueNotification = new NotificationCompat.Builder(getApplicationContext())
                    .setContentText(getText(R.string.notification_service_content_text))
                    .setSmallIcon(R.drawable.ic_stat);
            overdueNotification.setContentTitle(getText(R.string.notification_service_content_title));
            notificationManager.notify(2, overdueNotification.build());
            image.setImageResource(R.drawable.ic_stat);
            image.setImageResource(R.drawable.ic_launcher);
        }
    });
