如何访问 ARE（我的包 R）以在服务中使用 Drawable 图像

Question

public class HelloService extends Service {


...
..
NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        Intent resultIntent = new Intent(HelloService.this,MapActivity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification.Builder mBuilder = new Notification.Builder(this);
//        Notification.InboxStyle style = new Notification.InboxStyle(mBuilder);
//
//
//        mBuilder.setStyle(style);
        mBuilder.setTicker("Notification.Builder");
        mBuilder.setWhen(System.currentTimeMillis());
        mBuilder.setNumber(10);
        mBuilder.setSmallIcon(android.support.v4.R.drawable.notification_icon_background);
        mBuilder.setContentTitle(title);
        mBuilder.setContentText(contents);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
        mBuilder.setContentIntent(pendingIntent);
        mBuilder.setAutoCancel(true);

        ***mBuilder.setSmallIcon(R.drawable ....);***

*//这里想用图标来显示。但出于某种原因，我不能使用 R.drawable（com.org.smartapp 这意味着我的包裹）。只有 android.support.v4 等....如何访问可绘制文件以将其用作图标？在扩展 activity 的其他 Java class 文件上，可以像下面那样具有 R.drawable 访问权限。 *
